I have grown and had some wonderful broccoli with lovely heads of about 6". So deliciously sweet and tender. Have had lots of compliments on it from other growers who have had no success. The variety is F1 Green Magic.
Prior to planting the little plants out at the beginning of April, as usual I raked in some growmore about a fortnight before. I picked the first successful heads as above last weekend and the plants now have lots of little side spears which I would like to encourage to grow larger. My question is, do I need to add some more GMore now or at some point or some other fertiliser to get them to mature nicely? Would this encourage them to grow ok? I don't want to be disappointed with them boulting and/or becoming loose and seedy headed.
What do people think?
