Dear Indigenous Enthusiast

We have all survived 2012 and the end of the world and now look forward to 2013.  I wish you all the best and may all your dreams come true and you live a peaceful and happy life.



When visiting Random Harvest look out for the Peltophorum africanum (Weeping Wattle) and the Bauhinia galpinii (Pride of de Kaap) on the left as you drive down the road.  They are putting on a wonderful show with yellow and terracotta flowers.


The veld is also looking really great with all the grasses coming into seed.  Walking in a grassland is really beautiful and interesting, with things to make you wonder at the beauty of this planet with each step you take.

The grasslands are such an incredibly rich habitat with their diversity of plants and wildlife that it could take you hours to cover 10m.

To recreate this wonderland and increase biodiversity in your own garden we have cultivated a variety of grasses, wildflowers and bulbs to help along the way.

I know early in the season the variety of grasses in stock was limited but we have remedied that and now have a good selection.


The Bauhinia tomentosa are coming into bloom and look lovely.  This is an underutilised plant in gardens which is a shame as it is a beautiful shrub that can grow quite untidily but if you take the time to prune it into shape twice a year it is a really rewarding, long flowering shrub for the garden. 

It can be used as a backdrop or even as a more formal hedge. 

The added bonus is that it is a host plant to butterflies and moths making it as useful as it is beautiful in a biodiversity garden.

We have stock of 4 Litre and 20 Litre plants.

I must say all the Bauhinias are looking good. 

One of my all time favourites is Bauhinia natalensis

I just love their pure white flowers with maroon nectar guides to encourage insects to pollinate them. 

Another good addition to a wildlife garden. 

This plant makes a wonderful delicate hedge.


At last I have managed to grow some Kirkia wilmsii (Mountain Syringa).  This magnificent tree is definitely only for bigger gardens as it has quite aggressive roots and can grow big.  But, if it is autumn colour you are looking for this tree is hard to beat. 

If you are ever driving near Strydom Tunnel on the way to the bushveld in autumn look at the hills around you and you will see the beautiful red and pink colours of the Mountain Syringa adorning the hillsides.

The silvery-leaved Gazania uniflora Pink are also looking lovely.  Remove the dead flowers regularly and you will be rewarded with flowers all year round.

Another long flowering perennial is Scabiosa columbaria (Purple Scabiosa).  The plants in the nursery are a dance floor for the butterflies.  There are so many of these winged beauties that their fluttering amongst the flowers which sway gently in the breeze makes for an incredibly beautiful duet.

Amaryllis worms


Amaryllis worms (or Lily Borer) are enjoying our wet summer and have come out in force.

These disgusting black and yellow caterpillars that cause so much damage are the larvae of a very insignificant dark moth which is indigenous.  The population has exploded because we have changed the environment so much.  Gardens are moist and densely planted, which creates a perfect habitat for these unwelcome creatures.

The moth lays a cluster of about 50 eggs on the underside of the leaves of bulbous plants. On hatching, they bore into the leaf and eat their way down towards the bulb. If they are not ready to pupate by the time they reach the bulb they will even eat their way through that, and down to the basal disc which totally destroys the plant.

If you have just a few plants of the Crinum (which they will eat but not kill) Clivia, Agapanthus, Nerine etc then it may be possible to remove eggs just by rubbing them off.  You will find the clusters of off-white eggs under the broadest leaves. 

If you have too many plants to do this, we suggest using an organic pesticide such as Biogrow "Pyrol" with this you actually have to spray the pest to kill it as it has no residual effect on the plants.  One of the best solutions is Margaret Roberts "Biological Caterpillar Insecticide" mixed with Ludwig's "Spray Stay". 

This is a bacteria that when eaten prohibits digestion of food, resulting in the starvation and death of the Amaryllis worm.  It is important to use the "Spray Stay" to stick the insecticide to the leaves.  Do this every 2 weeks and you should be in reasonable control.

Another thing you can do is use Crinum moorei, which is the favourite food of the larvae, as bait and then spray the worms.  The plant will look ugly but it makes control a whole lot easier.

Good Luck - this and Citrus psylla are the pests I battle with most in the nursery.

Tea Garden

Frans and Yolam have made the most delicious savoury cheesecake you have ever tasted! With a fruity side salad, this is a sublime light lunch-time treat. It will be available at the tea garden from Saturday the 5th of January.

New Year's Resolutions

I thought of some new year's resolutions that will help you connect to nature and enjoy your garden even more.

" Plant only indigenous plants
" Spend more time in the garden, observing and contemplating
" Think about creating habitat and inviting creatures to share your wildlife garden.
" Start a visitor's book for your garden - make a list of all the creatures you see in your garden, where and when you saw them and what they were doing. Embrace your garden with all your senses
" Walk barefoot on your lawn - experience the earth from your toes up.
" Plant and use fresh herbs from your garden

Christmas 2012 activities at Random Harvest


From the 8th to the 19th of December we had wonderful fun at the nursery.

Thanks to all those who attended our Christmas activities… we hope you had as good a time as we did. 

It was great to get the positive feedback, as we always value your input to make things even better next time.Here are a few pictures of what we got up to.

A fascinating morning with Geoff Lockwood, looking at how to identify birds.


Decorating Christmas gift wrap and cards.

Creating Christmas decorations from mostly natural and recycled items.

Garden Safaris - all proved very popular.

It is amazing what one can discover when you take a closer look at the garden.

As you can see from the pictures the children were totally fascinated.

     The toddlers love looking under rocks but especially loved the mud which was part of the sensory walk we made for them.

Mixed media frames for adults and mosaicking for children.

 From the 10th of January we will have some information on how to make some of the lovely decorations, cards and gift-wrap that we created at our workshops.

Please remember to check our website from time to time - 2013 will see a number of events that are sure to enhance the exciting year ahead of us.

The bird walk with Andre Marx was, once again, an amazing morning - sighting 60 bird species in just 2 hours. 

Aren't I lucky to live here?


On the farm


The grassland on the way to the dam is looking marvellous. Chironia purpurescens and Walenbergia caledonica which first appeared 2 years ago are now growing in patches all over the place


The dam was full of Azolla filiculoides that tiny little alien water fern that turns red.

I hate this invader especially as it sucks the life out of the dam.

My solution was, on the hot days, to have Mongezi wading into the water to remove it. 

This does seem to be a bit fruitless as it grows so quickly.

The Plant Protection Research Institute in Pretoria released a bug which kills it. 

They no longer have any of these bugs as they were so successful.

I tried to be patient and not remove the Azolla in case there were some bugs on it but the dam was so covered I just had to remove it.


This is the best picture we have been able to get of the baby Moorhens (not very good) but I am just happy they survived. 


The Egyptian Geese have left with their babies so the birds are slowly coming back to the dam. Including the poor Black-headed Heron which we chased to save the Moorhen and Egyptian Goose babies.

The farm geese have had so many babies that we are overrun. This picture is just a portion of the flock.

If you know anyone who would like some geese let them give me a call and they can happily have some.

  What a great addition to a biodiversity garden is this Combretum padoides (Thicket Bushwillow).  As you can see from the pictures there is a stinkbug and a bee on just a few flowers.  The plant was literally humming with life which just adds to the beauty.

We must be doing something right.  How beautiful is this little Red-lipped Herald?  He was in amongst the seed trays doing his duty keeping the seedlings pest free.  I just love it!


Thank you for reading my newsletters each month.  I really do appreciate it and feel humbled sharing my wonderful life on the farm with you.
