Last Meeting:
Ann Duckworth, from Pietermaritzburg gave an informative talk on growing specimen plants
accompanied by slides of award winning specimen plants that will serve as inspiration to us all to
attempt to grow at least one outstanding specimen plant. Remember, not all specimen plants are large
and heavy; there are species that form small and compact specimen plants like Masdevallia tovarensis.

Plant Table:
We had a small plant table consisting of 4 species and 21 hybrids which was ably handled by Ann
Duckworth and Dan O’Connor.

The winners for the evening were:

Best Species           Oncidium maculatum                                  Maqrgaret Rumsey

Next meeting :
One of our favourite guest speakers, Hendrik Venter, will be joining us to tell us more about the Durban
Botanic gardens and its extensive orchid house, of which he is in charge. Hendrik is a very
knowledgeable and entertaining speaker so please don’t miss out on this opportunity!

Culture corner : How to control red spider mite
Although they are extremely small, red spider mites can rapidly build up to great numbers in the right
conditions, making them one of the most destructive pests in the garden. Hot, dry, dusty conditions lead
to spider mite problems - they are often worst in greenhouses and conservatories. These conditions
encourage the mites to feed often, causing damage to the plants every time they feed. Cool, moist
conditions can help to reduce spider mite populations by restricting their breeding.
How do you identify them? Spider mites are tiny wingless insects with eight legs and a one-piece
body. Red spider mites (Tetranychus urticae) are also known as two-spotted spider mites or greenhouse
spider mites. Adult red spider mites are 0,5 – 1mm long – olive green in colour with two dark grey spots
on their backs. The first signs of red spider mites are either small spider webs often high up on the plant
or white speckling on the upper surfaces of the leaves.
What is their life cycle? Miniscule 0,1mm round translucent white eggs hatch into white six-legged
larvae. The females lay 4-6 eggs a day, starting when they are 36 hours old. The whole life cycle can
take as little as three days in hot conditions – though in cooler weather it can extend to a month. By early
autumn the shorter days and slower plant growth slow down and then stop their reproduction. The
remaining females turn red and find sites to over winter – in the soil, on tree bark, on greenhouse walls
and on pots. The first adults seen in spring are bright red.
What do they do? Red spider mites damage the plants by sucking the sap – feeding under the leaves
and causing white speckling on the upper surface of the leaves. As mite numbers increase the speckling
will spread, the leaves will turn yellow and fall off. In hot dry conditions areas of high infestation will often
have small spider webs. Red spider mites can ruin foliage and even kill plants.
How do you control them? When bringing new plants home, always make sure that they are clean of
mites and other nasties by checking the tops and bottoms of leaves. If you are not sure, keep the plants
quarantined for a few days and check again. Spray plants with Vertimec and a wetting agent like
Bladbuff, which is very effective against red spider mite. Spray 3 times - 7 days apart, saturating the
undersides of the leaves. (Supplied by Des Gillespie)
