Have grown broccoli before with great success in the backyard vegie patch,just a bit concerned with my crop at the moment with lots of long healthy leaves but does'nt seem to be any sign of the main flowerhead yet. It's been awhile since I grew the last crop and I can't remember when the flowerhead appeared or will they just grow through the long leaves,there's no sign of seeding yet either?

Yes you can eat the flowers and buds , the Chinese do! Taste lovely in salads and the flowers can be deep fried in batter

Dogs are great like that. I love my dog but she does get in the way of my gardening. I put a strip of gaffa tape over the top of the jar that I embed in the soil, that way my dog can't stick her snout in. I only fill the jar up half way too. I've always been very anti-poison, but because of Tassie's bumper winter rainfall and summer heat the slugs are terrible this year, so I stuck some bait in a takeaway container with a hole cut out in the side. That way the dog can't get to it and the soil isn't contaminated either. Mind you the slugs still exist, it just slows them down a little...

I experimented with lemon or orange peelings last year and it helped with the snail and slug problem. I put the peelings inside a container near the veggie bed in the afternoon. Early next morning, many snail and slug in the container. Easy method to dispose them.

For slugs & snails a small jar buried to its top in the ground half filled with lite beer works best.You can then use the reamins as fertilzer for the bed. If you can't be bothered grinding up soap you can buy Lux Flakes that everyone used to wash their baby clothes in which you can then mix up with boiling water and dilute with cold water. Throw in some garlic, lemon and chilli, marinate over night, strain and water. You can't go wrong (hopefully).

Only problem is the dog drinking/eating the beer/slug/snail mix. Clearly too tasty!

I use eco oil, it works fine.

Here is a really simple safe and terrific solution for those nasty caterpillars that eat broccoli. Just grate some ordinary toilet soap into a saucepan, about 1 tablespoon into a litre of water, heat it and stir until its dissolved and spray it thoroughly onto the broccoli. It may have to be sprayed again after rain. It works incredibly well in my garden and I never have a problem.

Why does our plants only produce really small main heads of broccoli, the plants appear to be really healthy.
