Hi!I've growing T. pavonia in Z5a with a contionental climate. 1/3 sand 2/3 coir pith with Osmocote Plus (15-15-15). In a 22 cm (8,7") diam plastic pot (height is also 22 cm). The bulbs are planted 2-4 cm deep under soil level. I had one bulb with 3 offsets. They were on a semishaded spot, but with about 3-4 hours direct sunlight. Thips are like to suck on their leaves, this is bigger problem here than any else. In that nearly 5 liter pot I gave about 5 ml osmocote.They were very well, but as I was so busy this summer the pot dried out many times, so only 3 bloomed. But bulb growth was as nearly good as in the Netherlands. In our sodium-alkaline clay they did not feel too good. After a year i discarded them, sometimes the bulbs were infected with root sucking aphids, which were between the bulbs cales, but in this mix they were quite well, better than ever!So if your summmer is hot (~35°C =95°F, daily) but nights are getting soon cold (some frosts may occure in the middle of october) this should be good. Bulbs stored totally dry!Bye,Jani, Z5a, Hungary-- Eredeti üzenet --Feladó: Dennis Szeszko <dszeszko@gmail.com>Címzett: pbs@lists.ibiblio.orgMásolat: Elküldve: 2007.02.18  23:33Téma: [pbs] TigridiaPam:  >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. _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://www.pacificbulbsociety.org/list.php
