Hi hanzrobo, I have an east facing and a huge south facing window. I was a little concerned that if they slow down in the heat of summer, seedlings may have a tough time right now. We are already 100+ and the room they will be in is warm! It's an add on to the house, but no cooling attached. I'm thinking of ordering seeds from Mesa Garden , unless someone has a better suggestion. :-)

so many questions, so little time...briefly: transplanting is pretty safe any time of year except when it is hot, just make sure the new soil is dry and the plants shaded for about a 7-10 day recovery period before you resume normal conditions during the winter is when they need as much light as you can find, either direct sun in a greenhouse or strong artificial light as a supplement. if conditions are cool enough you can get away with less than ideal light intensities since the plants will have slowed down. i can't speak to your clay vs plastic struggles without more details. what is your soil mix? x

Sorry, having trouble typing comments on here) & the lithops ripped completely in half. :0( I just set it back on top of soil. What happens now?/will it possibly reroot, or will a new plant grow from old roots, which I left in soil? I'm so p/o'ed this happened! I had had these for over a year & was so happy to feel like I had accomplished finally learning how to grow them. Learned mmy lesson, I suppose. From now on, I'll just leave the outer leaves alone.

I HAVE to share my cilantro growing experience from last year. Last year was the first time I grew cilantro and I planted seedlings in June when it was getting pretty warm. I broke almost all the rules, mostly unknowingly, and it still worked very well. 1) Split each seed into two halves and sowed four halves 1/4 inch deep, equidistant from each other in 2.5 oz cups, about 2 inches across and 2 inches deep. 2) germinated on heat mat. Took almost two weeks to germinate even on heat mat. Most germinated. 3)As soon as I saw any germination in a cup, removed it from heat mat and placed in enclosed porch where they got morning sun. 4)when all the seedlings had at least one set of true leaves planted outside, about mid June. 5) The site was pretty shady, only 3 or 4 hours of sun. The soil was rich, soft and fluffy. Inverted the ball of soil out of the cup, nudged into the soft soil, mulched and watered. ALL the little seedlings grew into big stocky plants! I crammed what turned out to be 24 to 30 plants in a 2 feet by 3 feet rectangle, or smaller. In spite of the little sunlight and so many plants in such a small space the cilantro grew upright, vigorously and had fantastic flavor. And here is the kicker. I harvested leaves by holding a bunch and cutting straight across about 1 or 2 inches from the ground. For most part I did not cut all the leaves off a single plant but a bunch here and there from my dense clump. By the next morning I could see new growth at the cut surface. I cannot emphasize just how much cilantro I cut and harvested from this clump for myself and my friends. And I was harvesting till a little before Christmas until iit suddenly got too cold and I did not want to trek outside anymore. The plants were still growing back in Nov. Not a single plant bolted till mid November and then only a total of three plants flowered. The flavor changed late in the season. Dont know if this was because of the season changing or the plants getting spent. Still pretty full of flavor. I did water well and fed them with fish emulsion + kelp extract a couple of times. So, I germinated inside on a heat mat, transplanted outside in hottish weather, grew in mostly shade, harvested over and over and got cilantro into December from a planting from June and almost no bolting. I attribute all the good things to the variety I grew, Calypso. I bought three varieties, Calypso, Santo and Cruiser, just picked them out of a hat. I could not get a single seed to germinate from Santo or Cruiser so Calypso grew by default. That was one of the luckiest breaks. I am reading the description of Calypso carefully now and it does say very slow to bolt, can be cut again and again and makes big plants. The Calypso was from Park Seed. This year I will plant out earlier. @floral_uk z.8/9 SW UK my last frost date being April 25, I will try beginning of April? @kitasei2: Please give Calypso a try. I think it will work for you. You will get big bunches of cilantro. Same as you, last year the flat leaf parsley I tried germinated in a few days, a blink of an eye. I soaked the seeds overnight and germinated on a heat mat too. I planted them out so late they did not get very big though. Maybe they wont come back this year.
