Growing Tips
Below are my “tips” allowing anyone to build up a good flowering collection of cacti and other succulents that will give you and friends many many hours of enjoyment. Download these Growing Tips to print them and have them readily avaialble.
Cacti and Succulents
Although Cacti and other Succulents can be grown indoors the best situation is in the greenhouse/conservatory therefore my treatment recommendations are based on that in the UK.
Summer
After the winter period gradually introduce water from mid March until you again reduce the watering to nothing in mid October. During the height of the summer you should be watering every 5 days, with the occasional light spraying during the odd evening when the sun is not shining into the greenhouse.
Pests
Mealy bug or red spider are the two main pests that can surface with a collection of cacti, but early treatment with most sprays available from your garden centre will help eradicate these.
Winter
From mid October until mid March no water must be given to the Cacti, to enable them to hibernate, but also the temperature must not go below 5 degrees Celsius.
Compost
There are many “ready mixed” Cacti composts available, however the mix I find best is:-
- 1 part “John Innes” No. 2
- 1 part Pumice (if not available Perlite)
- 1 part COIR Compost
This gives enough retaining qualities in the mix for water but also allows root ventilation and drainage of the final mix.
Watering Instructions
After the winter dormancy period gradually introduce water from early May when the old plant bodies have virtually shrivelled away and the goodness has been taken in by the new emerging plants. From August I reduce the amount of water given by 50% until it is stopped in late September for the Winter period. Younger plants may require 1 teaspoon of water every 6-8 weeks over the Winter, just to keep them ticking over !
Although Lithops like the heat in a greenhouse they must also have “fresh air” circulating as they do in habitat. This is very important so that plants do not become scorched and damaged.
