if you look at the planting 'timetable' it indicates sowing seed in Feb and PLANTING out seedlings 4-6 weeks later. So, yes I'd be getting seeds into trays now ready to plant out when your tommys finish =)

I have fabulous success with broccoli year after year. I have a couple of tips that help prevent/delay bolting and a question. Tips: Keep broccoli moist. Never let it dry, especially during warmer weather. To retain moisture and drastically reduce weeds, use a heavy mulch. I use hay and I add a layer as soon as the bottom layer starts to break down. One bale of hay will mulch about 100' sq and costs about five bucks. I grow my broccoli with collards, cauliflower, cabbage, carrots and onions during the cooler weather and with whatever survives, pops up or I get around to planting (cause we have 5 growing seasons here). Now the question: Although I can grow broccoli that's so green it's blue, is 4' tall and 6' around and produces side shoots for three months...my husband HATES the variety! I'm aware of the difference in the flavor of this particular variety (Waltham 29). It has an extremely dense taste, similar to asparagus, which I love, but Eddie refuses to eat it so it's pointless to grow it! Any suggestions on a heading variety (heat tolerant) that's more like the market variety? I collect my seed, so I try to find heirlooms, open pollenated.
