i live in hanmer springs, i have grown broccoli under greenhouse to protect from harsh frosts we get here. they have grown all through winter and i harvested the heads few weeks ago, and have been eating the side shoots ever since. june july they stopped growing hibernated, but last month has seen warmish temps so evrything has shot away. greenhouses are great.

First time of growing broccoli we had brought from nursery and planted they have just not long got a head and have notice that there is little ones on the plant also from what I have been reading through that doesn't usually happen til after the main head has been cut but for some reason it is just wondering if this has happened to anybody else

My broccoli last year/this year were like that. My plants were way too big (too much Nitrogen) - all leaf and very little heads. Try planting after a crop that has used the N and if you have to, add a bit of fertiliser when the plants are half grown. A small amount.

Thanks for that I do put seasol on them every couple weeks as I have a few different things growing in the same area so it all gets done

If you prepare your ground before hand and have added compost/manure/fertiliser then the plants won't need any more feed while growing.

I'm growing broccolini, they are shooting but they're changing into yellow flowers. what should I do? this is my first time ever that I'm trying growing them. Thanks

You should have picked them before they flowered.
