I think thinning them to their own pots did get them growing bigger faster...now to transplant them to the garden.
I also started some cabbage and kohlrabi a few weeks ago. These are the survivors...most of them got a little too hot, when I had the heat lamp in the greenhouse.
On Mother's Day, we got started on building the raised beds...

since our topsoil is about an inch deep, with clay and rocks below it,I'm hoping this method will be successful. He has lots of information about this method on his website. One of the key elements of this approach is what you fill the beds with...1/3 vermiculite, 1/3 peat moss and 1/3 compost (from a variety of sources). I ordered my vermiculite through Horsefly Hardware...excellent service, by the way...she can order just about anything you can imagine a hardware store to carry and it arrives a week later, no need to drive to town! Hoping to have all of the components ready to go this week-end.
