Well, I grow my Tecophilaeas in the same mix I use for my Cape bulbs (such as Lachenalia). I also grow them on exactly the same schedule and watering as those. They come up a little later in the fall, but otherwise I grow them under the same conditions. I also don't water during the summer. But I do keep the dormant pots in shade all through the summer. So they may still get as warm as ambient temperatures, which are often in the 90's F (upper 30's C) during the day. My mix is based on a standard potting soil made of peat, sand, shredded bark, compost, etc. mixed with generous amounts of gravel, Turface, very small scoria, pumice, and commercial cactus potting soil so that it is very well drained, but still retains plenty of moisture. I will re-note that summers in Chile and California are significantly drier than in the other mediterranean regions of Australia, South Africa, Maui highlands, and the Mediterranean basin.
