Orchids deserve to be shown off. I think most would agree they are rather notably impressive plants that really deliver on gorgeousness. I challenge all gardeners to take the opportunity to get them out of pots and green houses and into the spaces where they would occur naturally. It’s obviously best to grow the species the are native/indigenous to your area. There are thousands of species all over the planet, even in the northern hemisphere. They might not be as showy as the ones you can buy in the supermarket but the are still really pretty and can add a very special point of interest in your garden.
I am really fortunate to have a huge clump that was growing in a Bridelia micrantha.
I’ve cut off some chunks and this is what I’ve done to replicate it’s natural habitat:
1. Taken a log and gouged some grooves into to accelerate its rotting process. If you have a log with a rotten core, plant immediately into the hole, ignore cardboard step.
2. Tied some cardboard with a 200mm ‘lip’ to create a ‘bough’ in tree.
3. Filled it up with wood shavings, leaf mold, soil and a bit of compost. Tied some hessian to hide the cardboard.
4. Added the magic mixture of 2:3:2, accelerator made from chicken pooh, and lime
5. Planted the orchid. By the time the cardboard etc. has rotted away the orchid will have attached it’s roots to the log
I’ve also attached a clump to a living tree creating a hammock with a stretchy fabric. I’ve filled the hammock with the same mixture as above and once the roots have taken hold will be able to remove the not very attractive acid green cloth. Probably about 12 months time.
Imagine our cities with birds and butterflies flitting from building to building. Imagine views from tall buildings that include roof tops full of plants, rich with life and colour and the sound of birdsong and insects. This is starting to happening all over the planet. People are seeking alternatives to the alienating and sterile world of concrete, without moving to the countryside. Roof gardens provide all of this and much, much more!
I have dreamed of creating my own green roof for so long it hardly seems real that it is now in. This post is about the benefits of green roofs and quite a detailed ‘How To’ guide for those who wish to do the same. Early inspiration came from the Green Roof Pilot Project (GRPP) at eThekwini which is testing various options that provide healthier urban environments. This project among others has shown that these living roofs (as they are also called) naturally increase biodiversity and are aesthetically beautiful, but there are numerous other good reasons to seriously consider installing one:
They insulate the house, reducing the amount of cooling and heating required
They lower the amount of storm water run-off
Improve air quality through the reduction of air borne pollutants, including harmful carbon monoxide.
They absorb chemicals and heavy metals from rainwater
There are positive climate change impacts via absorption of carbon dioxide and the release of oxygen during photosynthesis.
They help insulate for sound
They reduce maintenance cost of roofs and increase its lifespan by two to three times.
Can assist in the alleviation of food security issues.
Provide fire resistance
Offer electromagnetic insulation.
There are broadly two options for installation. One way to go is planting in trays. I have used the direct method which involves placing the shallow amount of growing medium on top of various protective and drainage layers which I will show step by step.
Before you start though it is imperative to ensure a structural engineer has confirmed that your roof can take the extra load (or if you are building from scratch engineer into the design).
Layer 1: Waterproofing
We began by installing a serious waterproofing product called ExtruBit ® . This stuff looks a bit like wet suit material is flexible and really tough. A company called Bertrade did the installation which involved heat sealing the overlap areas. No mean feat in Durban’s hot and humid February.
The next three layers provide the drainage and help ensure the soil won’t get into the full bores. Pula Water supplied their amazing drainage mats (Flow-Cell ®) which are sandwiched by geotextile. This was a cinch to install, somewhat reminiscent of playing with Lego as you are rewarded with a very satisfying click as each mat slots into the other! In addition to ensuring the water will drain
Layers 2 & 3: Geotextile (white) then Flow Cell mats.
away they are designed to do so slowly so plants have time to drink.
You are now ready for your soil mix. My soil has come out of the ground being dug for the water harvesting tank. Not very nutritious so I have mixed it half/half with pine bark compost from Grovida.
Soil coming up on the conveyer
In addition I have added bags of organic accelerator, agricultural lime and 2:3:2. Over and above general dispersal of the above, each largish plant hole received a handful of the extras to give a nutritional boost.Before we talk the about the most exciting bit which is obviously the plants I have to share with you the less interesting but vitally important info on how to deal with your full bores. This is the area you roof garden will ‘fall’ to (i.e. slope down to) and it is crucial that you have sufficient drainage or your garden will fill up and swim over the edge of it. To help slow down the process in the event of heavy rain this is what you can do:
1. Cut or drill holes/grooves into a section of pipe that is the diameter of your full bore and height of your garden. Thanks Geoff!
2. Position directly over full bore
3. Surround the pipe with aprox. 500mm width of gravel encased by bidum
4. Cover with rocks
5. Plant around as you wish
Choose your plant species carefully. It goes without saying your locally indigenous/native plants must be selected and these should be water wise and heat tolerant. Plants that grow in cracks and crevices are ideal. Bear in mind that the soil is shallow and will dry out quickly. Plants should (in the main) also be low growing and wind resistant. Ideally they should also be self seeding to replace themselves when stressed by heat and water fluctuations.
They beauty of using the correct plants means that after they have been established irrigation is seldom required. Plan to utilize at least one of the many water harvesting options. Gutters and grey water re-cycling are easily installed. (Detailed posts to follow).
Ecstatic me planting at last!
For those of you in Durban South Africa here is a list of plants that will do well:
Aloe van belanii, Crassula, Euphorbia, Venonia capensis
Gorgeous hardy indigenous treasures.
I know this garden will give us much joy in the years to come. I hope you’ve been inspired!

P.S. I know many of you are desperate for the post on the Vertical Garden. The scaffolding is still in front of it and the minute it’s down I’ll be able to show you it in all its early splendor. Here is a little glimpse of what is flowering at the moment.
I have developed quite an emotional attachment to my worms. For good reason, they are truly amazing and greatly underappreciated creatures.
Gardeners Gold. the result of vermiculture is the Rolls Royce of compost
If you haven’t yet discovered the joy of worm farming I urge you to give it a go. For the yet to be initiated:
Vermicompost is the product or process of composting using various worms, usually red wigglers, white worms, and other earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Wikipedia
Earthworms aerate, till and fertilize the soil, breaking down organic waste into plant-available forms, improving the soil structure and nutrient and water-holding qualities of soil. Current farming practices that use chemical fertilizers, pesticides and over-tillage of the soil kills earthworms and other beneficial organisms, leading to poor soil fertility, loss of soil structure and soil erosion. At the same time, rotting organic waste dumped in landfills is polluting our underground water supply and releasing vast amounts of greenhouse gases which contribute to global warming.
Earthworms eat organic waste and give us healthy soil and organic fertilizer in return. The knock on effect is healthy plant growth and food that is significantly more nutritious and delicious. Farming/gardening without man-made chemicals enables us to avoid poisoning our soil, environment and bodies. This perfect partnership is easy and fun to develop on a smaller scale at home.
There are numerous commercial systems available but you really don’t need a hi-tech operation to get started so go with what your budget allows or make your own. My
Worm Farm. Simple design. Effective.
son has designed this ingenious system which enables us to maintain the health of the farm and easily harvest the ‘gardener’s gold’. These simple re-cycled plastic boxes are divided by a section that has holes cut into it. One side of the box is filled with food until full. At this point we begin filling the other side leaving the first side to break down further. As the food disappears the worms will move into the food rich section leaving behind the easy to harvest worm castings which contain up to 100-million microbes per gram – up to 20 times more than ordinary soil! Added to your garden, these microbes continue to break down organic matter into plant-available forms, thereby enabling plant roots to take up nutrients that would otherwise have stayed bound in the soil. These beneficial organisms also suppress the growth of pathogens, which means healthy soil and healthy plants. In addition to harvesting the castings we catch the worm wee (leachate) which drips through a hole in the base. It makes a wonderfully nutritious tea when mixed with water. Tea for plants that is :-).
Rat nibbled aeration patch
My farms, however, we getting a bit to much attention from other wildlife in the garden. I realised that the aeration patches had been gnawed through and at least one rat was feasting on my red wrigglers. I’m all for ‘the cycle of life’ etc. but realised my population was taking to much of a knock. It was time for some maintenance and harvesting anyway so I got stuck in. The old aeration patches
Air vent repaired with rat proof metal mesh
were replaced with wired mesh, the harvestable sides were harvested, the worm filled sides set aside and the whole box was given a good clean. Worms were returned with a note on top to advise other family members to now only feed on the one side (yes it is necessary in my family!). Worms are now safe from predators and I have buckets of gold to mix into my veggies boxes.
repaired and restored
P.S. I know many of you are very anxious to see images of the incredible vertical garden. I ask you to bear with me a little longer. The scaffolding will be coming down soon and then you will get a much better sense of this exciting project. If you can’t wait to get started on your own VG but need some help, get hold of the plant wizard James Halle on james@halle.co.za.
Beautiful organic harvest grown in gardeners gold fed soil
The build seems to have accelerated, or maybe its just because we are starting to get to the best bits. The most exciting installation, so far, is the vertical garden. I’m going to be really mean though, and not show you a single picture yet because it is so magnificent, and the landscape artist James Halle is so talented, it has to have its very own post with lots of elaboration. Watch this space!
Floating staircase
The shuttering has come off the ‘floating’ staircase, and although this is not a green aspect of the build it is so beautiful I just need to show it off!
The interior painting has commenced. There are loads of eco-friendly paints on the market these days. They are much lower in volatile organic compounds (VOC’s) which basically means toxic stuff our bodies don’t like. Confirm this with your paint supplier though because you won’t automatically get a low
Low VOC paint primer
VOC paint as there are still mixed perceptions about its efficacy. Rest assured, they are equally effective and no more expensive than traditional.
Mesh lining veggie box
The veggie garden now has 3/5 veggie boxes installed. We are using a plastic timber product. These recycled planks are now widely available. They are 100% recycled plastic so get great green points. We lined the base with chicken mesh too keep out the moles. Galvanized rods secure the sides from bowing out. This stuff will last forever, looks attractive, is easy to install and cheaper than recycled brick options which we had considered
3/5 Veggies Boxes Installed
Trichocladus crinatus
I was really excited to see my Trichocladus crinitus (Black Witch-hazel) in flower. This small indigenous tree is quite rare and the petal form delicate and unusual.
Insualation Made From Recycled Plastic Bottles
There are lots of eco-friendly options for insulation these days. We’ve gone with a product made from recycled plastic bottles. The recycled newspaper product was a close contender. The team on site report that the green stuff is really great to work with as it doesn’t shed prickly bits like the more traditional pink products.
Off Shutter Concrete
The off-shutter concrete wall has had its first of two buffs and polishes. It looks fabulous. I love the industrial /contemporary aesthetic and the honesty of the material. Its a great ‘hard’ contrast to the green abundance of the garden. Very happy with how its turned out.
Erythrina humeana
The Erythrina humeana (Dwarf Coral Tree) are exquisite at the moment. A really showy splash of red at the bottom of the garden.
The pool has a new rectangular shape and fits snugly into the space of the old. The reed beds are almost complete. It’s going to be great fun planting them up. I’ll be sharing much more information on how to install an eco pool. Suffice to say at this stage that the plants will do all the filtering of the water and no harsh chemicals will be required. The plants and water provide the foundation for the wetland eco-system and we look forward to the
New Rectangular shape to pool
Reed beds constructed
bird, amphibian and insect life we will be attracting.
Next to the veggie garden we have two of the Baunia’s in flower at the same time. Gorgeous!
Bauhinia natalensis
Bauhinia tomentosa
The whirly gigs are on site. Prith and Eamonn are finding them quite amusing. Definitely a first for them as they are usually found in industrial builds. We are putting them in to draw and pull up the cool air that will pass over the pond outside and into the hallway. The best way to reduce the need for air conditioning in this space.
Whirly gig
So overall fantastic progress! And still so many of the best bits to come:
Many think the subject of compost is about as exciting as watching grass grow. I’ve long been teased about my obsession with the stuff but noting the 1,397 books available on Amazon I know there is a community out there that are as passionate about it as I am. For example, this is what Bette Midler has to say:
My whole life has been spent waiting for an epiphany, a manifestation of God’s presence, the kind of transcendent,magical experience that let’s you see your place in the big picture. And that is what I had with my first compost heap.
I’ve struggled with compost ‘heaps’ in awkward spaces, then upgraded to bays in rickety fencing (now collapsing) so I’ve been determined to put in a more user-friendly system at the Gorgeous Green House. On the design wish list:
at least 3 bays for good rotation
sturdy construction
opening/gate front for easy turning over and removal
We have a lot of old paving to re-cycle on site so I asked my builder for a quote to build them with the bricks. Phew, quite a lot more than expected. Plan B was to ask a fencing company for a quote. Also quite a lot more than anticipated. This led us tho thinking ‘how hard could it be to dig in a few poles and fence them in’. We checked out the material costs (a fraction of the fencing company quote) and were further delighted to see the company makes gates that are super easy to install. The result is spectacular. I am thrilled as they will be really easy to use. I’ve had piles of leaves and weeds building up all over the garden so its been wonderful to get them into the correct place awaiting their final home in the veggie garden. Here is our process:
Fencing stapled around the frame
Poles cemented in and the ready made gates attached
Sticks into the bottom (for aeration)
Layers of ‘brown’ and ‘green’.
When presented with the concept of resilience in relation to garden practices words like sustainable, hard-wearing (as in strong) and healthy came to mind. All of these words describe any vibrant eco-system. The opportunity for the gardener is then to take our lessons from nature if we want gardens that will thrive without too much intervention. It is no coincidence that nature just goes about her business (if not interfered with) in a sustainable and resilient way. These are some of the lessons I’ve learned on my gardening journey:
SOIL HEALTH
During autumn nature provides her most important harvest: fallen leaves. This is the perfect cycle of replenishment to the soil and the provision of nourishment for all life in the ecosystem; yet we sweep up this abundant gift into plastic bags and send it off to land fill. Come spring we drive to the garden center and buy compost in more plastic bags. Mulching is vital for soil health and the quality of store-bought compost is not the same as that of its natural counterpart. Worse still is the application of chemical fertilizer. Over time it throws out the natural balance of minerals and nutrients and impacts on microbial and other life. So get mulching and with all your excess leaves, lawn clippings etc. then start composting to improve your soil health. Next investigate the fascinating world of vermiculture (worm farming). These little creatures can take your soil health even further.
PESTICIDES
Applying chemical pesticides is at best a short-term solution. It might kill the insect that you believe is destroying your plant but which has, in fact, been providing an important service. I’ve seen Cussonia spicata and Erythrina lysistemon infested with the most fascinating caterpillars, devouring every available leaf and yet the plant emerges stronger and more beautiful than before. (Don’t forget that a caterpillar is also a moth or a butterfly and who doesn’t want those lovelies in their garden!). Bear in mind that a poisoned insect often poisons other wildlife who feed on it and so on up the food chain. If you are desperate to remove insects, do some research on organic alternatives.
COPY NATURE’S ECO-SYSTEMS
Caterpillars and ants also belong
The most fun I’ve had gardening is copying what occurs naturally. I’ve done this on a largish scale at my conservancy (converting sugar cane into four biospheres) and on a tiny scale in my 1 500sq my town garden. What I have learned is that bio-diversity = healthy. Monoculture requires a lot more maintenance (intervention) and is therefore less resilient. Even surrounded with neighbours paved yards one is able to create, even in the tiniest garden a beautiful haven filled with birds, butterflies, gorgeous colour, cool tranquil spaces, movement, energy, sound and joy. I would recommend developing your garden with these plant groupings in order of priority:
Tranquility under the trees
Woodland section: Trees enhance even very small gardens giving us somewhere cool to escape the heat of summer and our homes are more comfortable without excessive direct light. When researching species, look for trees/shrubs that don’t grow to great heights and give you great ROI. By that I mean look for trees that attract birds and butterflies and have an appearance that you like i.e. great value in one plant! Don’t worry about planting them close together, in the forest they have to compete for light so they will make their own way. Think about which side of the garden you want the shade and plant accordingly. Bear in mind that some trees are deciduous (good for leaves) but you may lose the shade you want on your veranda in winter. Most importantly though, if resilience is what you are after, plant locally indigenous as they will need no attention once they are established. Once you’ve got your trees in think about your understory. These plants will need to change over time as the shade area increases. Once again, take a walk through your closest nature reserve and see what is growing happily. If it is attractive looking there is a very good chance it will be available to buy.
Alternative plants to lawn
Grassland section: Large expanses of lawn are much overrated. The argument for soccer and cricket falls short in most urban gardens as they are generally too small. Lawn requires more water, fertilizer, weed and insect treatment (and labour) than other parts of the garden. Grass is also mono culture and as far as attracting wildlife to your garden it has little to redeem it. Why not create a natural grassland habitat? There are so many gorgeous grasses that attract seed eating birds and an abundance of flowers, aloes, bulbs, small shrubs etc that are a visual delight and will provide hours of entertainment because of the wildlife they attract.
Tiny pond attracts mega wildlife
Wetland Section: Ok, the term Wetland may be pushing it for a small garden, but even the tiniest of gardens can support a small pond. They bring a wonderful element to a garden and require very little work. Even a large plastic tub filled with some water plants (e.g. Cyperus prolifer, Nymphaea nouchali, Nymphoides indica, Zantedeschia aethiopica) works.My pond is about 1.5 X 1 M and attracts multitudes of dragonflies, and birds including Woolly necked storks! If you’ve got plants in the water you don’t need to fuss with pumps and the like, the plants keep the water clean for you. You can even add some fish. My indigenous tilapia have been going for years in my tiny pond.
Veggie garden:On a macro environmental scale, agriculture (monoculture) presents a huge threat to the
Plant some veggies for the planet and your own resilience
environment and therefore the capacity for resilience of all life. If we all carved out a small space (even if it’s just a sunny windowsill) to grow some food we would be making a contribution to the resilience of the planet as a whole!
As the Southern Hemisphere is moving into Winter, Autumn first provides her most important harvest: fallen leaves. Natures perfect cycle of replenishment to the soil and the provision of nourishment for all life in the ecosystem. And what do we do with this abundant gift? We sweep it up into plastic bags and send it off to land fill. Come spring we drive to the garden center and buy compost in more plastic bags.
Where did we get this idea that leaves are unsightly and need to be done away with? When you think about it for a minute it really makes no sense. I appreciate that leaves on hard surfaces are not a good idea so lets sweep them into the flower beds where the mulching provides moisture and nutrition through the harsher winter months.
Exquisite winter colour well nourished by compost
Once you get excited about the difference it makes to your garden (check out my winter colour!) you get quite greedy for the stuff. I frequently stop on verges as I see people raking leaves into bags and ask them if I can have them. I get a few strange looks (and comments) but most people are too flummoxed to say no! hopefully I leave them with some food for thought.
Easy to make wire leaf cage
I am currently just making a big pile with the leaves but if you prefer a slightly neat tidier approach I’ve also made this very simple cage out of wire fencing.
In a few months beautiful quality compost for free!
In South Africa we have a long history of importing trees. Many came to us by accident and I expect many immigrants wanted reminders of home and planted what was familiar in their adopted country. Many very common exotic and alien trees are quite pretty and so prolific that many people are not aware they are not South African.
It could feel unnecessary or even cruel to remove a beautiful large specimen of say, a Jacaranda, Hibiscus or Frangipani so what would justify it?
Because exotic plants fall outside of their natural environment they often have to be pampered with extra water, fertilizer or sadly sometimes pesticides.
Professional Tree Fellers
Plants categorised as aliens go in the opposite direction. They are so comfortable in their new environment they multiply exponentially, crowding out indigenous flora, sucking up water and nutrients from the soil and reducing our biodiversity.
Exotic/alien trees may offer some food to some bird species but they will never fulfill all the requirements for feeding, breeding, resting and nesting that our indigenous species do.
Ficus natalensis provides all the nesting Hadida’s family’s needs in the bottom of our Gorgeous Green House Garden
Most of our other wildlife rely on our indigenous (native) flora for survival. Some are so fussy that only specific species will do. As aliens march onward crowding out indigenous plants all the life in the eco system in reduced.
Indigenous trees once established need no further watering or fertilizing. Perfect for the lazy gardener!
The joy that creating a natural wildlife habitat, rather than a garden planted just for its appearance, is an experience that our whole selves resonate with. It helps us remember that we too are just creatures in this amazingly complex and beautiful world.
Burchellia bubalina, fantastic indigenous tree for birds and moths. As beautiful as any exotic!
Ring barking process
Mushroom growth less than a month after felling.
Perhaps you’ve been thinking about taking the plunge to convert to or add more indigenous but are a bit overwhelmed by the idea of removal and wonder where to start. You could consider ring barking which will kill the tree off slowly and in the process provide a larder full of insects for birds and other wildlife to enjoy (and you to watch!).
Alternatively get in the professionals. They charge more to remove the stump but I think it’s unnecessary. Stumps don’t take long to become covered in fungi and mushrooms and rot away.
Sawdust for the Gorgeous Green House compost heap
One more tip: when choosing your tree feller ask if they will chip your wood and as a bonus you also acquire a mountain of organic matter to add to your compost heap (and prevent it from going to landfill :-)).
Once you’ve cleared space in your garden you now have the fun of selecting the replacements! I’ve got a list of my favourites for a Durban coastal garden. I’ve put them in a table describing size, fruit, flowers, wild life attracting properties, and what butterflies they may be hosts for. I am delighted to share. Just write a comment and I will mail it to you.
My best tip: get yourself a copy of Bring Nature Back To Your Garden by Charles and Julia Botha. If you want to get closer to nature this fantastic handbook, written without pretension and much humour will be a wise investment!
In 2007 NASA identified grass production as the number one agricultural group in the US at a staggering 23 million acres. The second-place cultivated crop was corn at seven million. I couldn’t find any equivalent figures for South Africa but I do know that we love our lawns and I wonder why.
Lawn requires more water, fertilizer and weed and insect treatment (and work) than other parts of the garden. Grass is also mono culture and as far as attracting wildlife to your garden it has little to redeem it. Using chemical fertilizers and pesticides have a horrible environmental impact.
Hibiscus praetuertus
Why not consider converting some of your lawn to a veggie garden or to planting more indigenous (native) bird and other wildlife attracting plants in your garden? Using your lawn as a small rug in the garden and not the carpet will change the way the space looks, feels and impacts on your local ecology. In addition you will save money on your water and fertilizer bill. It will be a safe for children and pets and your will have a reduced dependence on lawn mowers and their maintenance. Think also of the time saved!
At my Gorgeous Green House there isn’t a massive amount of lawn, but more than I want and I immediately need to create beds to propagate plants for the roof and vertical gardens. Digging up lawn is backbreaking work and you never seem to get all the roots out. This is an old permaculture technique that works a treat and really is the easiest and greenest way to lose the lawn.
Well watered cardboard. Thanks Vusani
1. Layer down some cardboard (you can also use newspaper). Water it to soggyness. This layer kills the grass and weeds by blocking sunlight, adds nutrients to the soil as weed matter quickly decays beneath the barrier, and increases the mechanical stability of the growing medium.
2. Add an approximate 10 cm thick layer of compost.
3. Add some further woody and leafy matter, wood chips etc. If you have access to manure, fantastic! These layers are now encouraging favourable soil microbial activity and worms and enhancing soil structure
Additional mulch
4. Continue to keep moist
5. In a few months the layers will have disintegrated and you are now ready for planting.
Rich, grass free soil ready for planting
Your plants will get a fantastic start often leading to improved resistance to pests and diseases and your garden will always be filled with the sounds of nature, bees, birds and butterflies. .
Veggie farming is great fun at the best of times but when you produce something like this what a great laugh. I must confess I’ve probably left them a bit long but they are still really delicious. Not quite as peppery as when small but many people would prefer that. Really delicious lightly sautéed in a little butter and salt.
Comfrey plant
Radishes have to be one of the most rewarding crops; they germinate from seed in 3 days and you harvest within 3 weeks. They are really good fun to grow with kids who can lose interest in a carrot or potato that can take months. My radishes (actually all my veggies) are nurtured with worm wee and organic fertilizers. In this instance Comfrey tea. The easiest thing in the world to grow and make. Just squish the leaves into a container (I use and old 5L product bottle), stick some holes in the lid (if you don’t it may explode) and leave in the sun to ferment. Then dilute into your watering can about 1 – 20.
I’ve had a long-standing love affair with my worms so I won’t short change their PR in this post and will give them one on their own. Suffice to say that their ‘wee’ is really leechate and once you’ve got over the squeamish bit they are fun, really easy to farm and really make a difference to the quality of your harvest.
Oh and look at this beautiful Dietes bicolour. The two beetles match with their yellow spots! It must be very tasty in there as all the flowers in my clump had these beetles on. If anyone knows anything about them please share.
