POSITION
Still wet, cold, windy and dark but beneath the gloom sap is rising and potting is hectic. Finish potting deciduous trees this month and add acacias to the list.
WATERING
Little watering required but be wary of consecutive dry days. Check drainage holes in pots and if trees are not draining properly lift them up and place coarse gravel under them.
FERTILISING
It is still very early to apply feeds but growth stimulants may be used. Once growth commences fertilisers may be used.
DISEASE CONTROL
Pests are waking up and whilst humans are still reluctant to go outdoors pests may be damaging little trees. Take the necessary precautions.
PRUNING
Pruning may now be carried out freely, stimulating growth by pruning on both deciduous and evergreens are useful.
POTTING
Deciduous trees may still be potted but take care with evergreens it is still too cold for them. Only pot when the onset of growth is obvious.
REMARKS
August days are longer but temperatures are still lower than in June. This area is still in winter, so take care not to do things best left to spring.

SUISEKI AND PENJING
The weather is conducive to collecting rocks as SUISEKI or for creating PENJING. It is also very healthy both physically and mentally to get outdoors and to enjoy a special closeness with nature.

POSITION
The shortest day has passed and days are getting longer but only marginally. The same remarks apply as for June.
WATERING
The water table is high and frequent rains and dull days often mean wet condi­tions but, take care! A few dry days and bonsai could suffer. The winds are strong and frequent, shelter delicate trees and pots! Ensure that pots drain correctly. 
FERTILISING
No point in fertilising this month - temperatures are too low.
DISEASE CONTROL
Snails and slugs are busy, use appropriate bait. Fungus spores may be active during wet humid conditions. It is never cold enough in our area to kill spores of fungus effectively.  Spray with fungicides if necessary.
PRUNING
Winter prune and design prune deciduous trees.
POTTING
This is a really busy potting month for most deciduous trees such as Celtis, Ulmus, Acer, Taxodium, Betula, Carpinus, Wisteria and Malus. Visit a nursery for soil and pot supplies. It is always preferable to take a tree for which a pot is to be chosen to the pot supplier for direct selection.
REMARKS
A month when enthusiasm is sometimes at a low ebb but soon sap will be rising. Enjoy exchanging views with like minded people and reading books and maybe even surfing the web on Bonsai and related topics.

Bonsai Things to do in Cape Town - June 2020

What to do in June 2020 

June is the start of a very busy period for bonsai, with many time sensitive activities:

·      Clean and disinfect your benches.

·      Remove dead leaves from pots and under benches as they encourage re-infestation of Summer’s pests, put down bait for slugs and snails.

·      Check that drainage holes are clear and that your pot is draining properly if not angle it on a wooden block making sure it is secure, and then correct the problem in Spring.

·      Spray Lime Sulphur twice, at weekly intervals, 35ml per 1litre, cover unglazed pots I don’t spray my evergreens as some people do, because I don’t like the awful colouring the lime sulphur tends to leave on the trees. I prefer to use Rosecare, Seizer + Eco Oil, Koinor or Plant Care.

·      If you develop Black Algae on your soil surface Copper Oxychloride WP works well without killing the moss.

·      Don’t let moss get anywhere near acacia, pine or cork bark elm trunks.

·      Time to shoot select and needle pluck multi flush pines and embark on a feeding program to build them up before candle pruning in December. Adelgids and mites seem very prevalent. I use the chemicals mentioned above in point 4.

·      Time to reassess the design of your deciduous bonsai, transition your branches from thick too thin to give you better taper, remove unnecessary growth, wire carefully.

·      Dead head azaleas (once the flowers have died remove them).

·      Check watering, Bonsai are extremely sensitive to drought and cold.

·      Potting time is soon here so gather all you may need and prepare your soil mixture.

POSITION
Some showers and cooler weather are on the way. Some bonsai may have to be moved into sunnier spots or shade cloth may have to be removed.
WATERING
As usual watering needs to be watched, especially if the weather is cool and overcast but no rain has actually fallen.
FERTILISING
This is the last opportunity for feeding as with lower temperatures and shorter days plants do not take up much in the way of nutrients.
DISEASE CONTROL
Many pests are going into hibernation but snails and slugs are active.
PRUNING
Do not prune deciduous plants as stimulating growth is undesirable in winter, plants need a rest period.
POTTING
Too late for autumn potting and too early for deciduous trees.
REMARKS
A balmy month as a rule and the last chance to mix soil in reasonably dry conditions. Mosses are starting to appear remember to leave small pieces when collecting so that regeneration takes place.
