Growing Broccoli in Southern MD
I tried to grow broccoli last year for the first time by direct sowing some seeds. They didn't grow very well and I finally ended up pulling them out. This year I bought transplants and I have some that are starting to form heads (yay!!!) My question is how do I tell when the heads are ready to cut? And how long do I let them form side shoots, assuming they don't bolt? When do people in SoMD finally call it quits with their broccoli? I'm also asking so I can plan for growing veggies in their place.
They're Packman broccoli from Lowes, in a raised bed (different from last year) that gets about 6-7 hours of sun. The soil is from a nursery, but I don't think it had any compost/fertilizer in it. I only gave it some 10-10-10 fertilizer about 2 weeks ago. I've been watering everyday because its been so hot and I feel like the bed is draining too quickly/much.
