Terrestrial Culture – October

Les Nesbitt’s Culture Notes from the October 2019 Journal

The days get gradually longer, hotter and drier this month. In a dry year there may be no useful rain in October. Keep up the watering while leaves remain green. Aphids can infest flower spikes so be on guard. Break off the tops of old flower spikes to discourage these pests. Microtis species flower this month.

Complete tuber removal by the middle of the month. These pots will have to be kept watered as long as the leaves stay green, hopefully well into November, to give time for additional tubers to form. Group these pots together to make watering easier. Diuris punctata plants may not die down until December.

Some seed pods will be ready to harvest usually on a warm day. Pick them as the ribs start to change colour from green to biscuit and before they split open and release the seed. Place the pods in paper envelopes & store inside in a dry place until sowing time next autumn. The cauline autumn flowering greenhoods will go dormant so once the leaves go yellow let these pots gradually dry out completely.

Sort out which pots to repot in summer. Stand small pots in a larger pot to denote those to make a show pot for next year. This applies to colony forming species which are expected to multiply.
