Giving up on Brassicas!
I've been more than 3 years at this and still not much success. In late January I planted a variety of brassicas: kohlrabi, cabbage, cauliflower and broccoli. Since my plants didn't do we'll indoors last year, I decided to wintersow some while starting the rest inside. I don't know what Im doing wrong. My seedlings are so small and fragile. It's been 6 weeks and they are not 2 inches high. They are bearing the first set of true leaves and one variety of wintersown cabbage is looking pretty good with 2 sets of leaves, but all the rest are lagging. All seeds were started in miracle grow potting mix.
About two weeks ago, i began fertilizing with very diluted miracle grow, then switched to diluted fish emulsion. The plants are looking better, but seem to be growing very, very slowly. They are under lights ( my usual setup which has always worked well for tomatoes and peppers). Its nothing fancy, but it works.
Each year, I have started them a little earlier than the year before, with the goal being to have strong seedlings in the ground by March 1. It seems I always end up late in the season and my plants are devoured by pests. Starting plants too soon indoors has always resulted in white flies, so I really don't think I want to start in December. For fall planting, Ive failed because of poor germination and when i did get things to germinate, plants remained small or died out because of the heat. Its just too hot to start plants outdoors in July and August. Guess I'll be starting them indoors this year. When do you start brassicas, namely broccoli, collards, kale and cauliflower?
Let me know what you do and how it works for you. How do you achieve a good size with your transplants? Is there something obvious that I'm doing or not doing? Thanks for your help
