Pam: From my experience, the most critical aspect of growing Tigridia sp. is to ensure that they receive a 6 month dry rest. If they are watered all year round they will almost assuredly rot. On the other hand, during the growing season, water the bulbs almost daily and ensure that the soil never dries out. Another important point is that Tigridia that grow naturally in the wild rarely offset and that they prefer to expend their energy on burrowing deep down into the ground (sometimes over 12 inches deep). In the wild, I often see bulbs sandwiched between two rocks deep underground or sometimes just growing in small pockets of dirt directly in rocks. I would recommend a deep pot with a mixture of sandy soil, pebbles and small stones as a substrate covered with a thin layer of leaf mulch at the surface. These growing conditions would most accurately reflect their natural climatic preferences. If you are undecided about the size of the pots, I'd recommend larger pots because they have the advantage of not warming up as easily as smaller pots provided that you can provide EXCELLENT drainage. What species of Tigridia are you planning to grow? -Dennis Just wondering if any of you could give me a few suggestions for growing Tigridia in pots. I?m doing this so a friend can shoot close up photographs of them. I know the basics including fertilizing. I?ll be using standard clay pots and am mostly wondering if I?ll need to start them in small pots and bump them up into larger ones as they grow. I?m also concerned they?ll get too hot in pots here in Scottsdale, even in my shadehouse that is covered with 50% shade in the summer. Thanks for the help.
