When I read Jon Evans report for the Summer Show South it was interesting to see Cacti in the prizes. Elaine and I have had an interest in Cacti, particularly Rebutia, for quite a number of years.If I may, I would like to share a few images of our small collection.

We use the same compost for our Cacti as that for the Saxifrages. Water from below when dry and feed occasionally with a liquid tomato fertiliser. Stop all watering and feeding from mid September until the middle of March, beware the Ides of March is a good aide memoire. We keep our plants in the cold greenhouse all year round with our alpine collection and apart from losing a couple of Mammallaria they have survived this last winter even though temperatures were dropping to -10c and below for days on end and only the glass to protect them from the elements.
