When you cut the head of broccoli will it shoot again and give another head? I have done this and now have tiny heads shooting Will they come to anything?

Ok I am in Canberra and first time broccoli grower...well even first time vegetable grower. I planted these seedlings around Anzac day. I am just now seeing a head forming in the middle. Some questions: Is there anything I shld be doing now to ensure this growth i.e regular fertiliser, covering plant to protect etc. There doesn't seem to be any problems with pests at the moment so fingers crossed. Just using snail bate at the moment. Any help would be appreciated. I really want to be successful at this.

broccoli leaves can be blanched 1.5 to 2 min. then can be used for stuffed cabbge rolls, their excellent

Trish, your broccoli plants need their leaves to grow good size heads. So keep trimming to a minimum. Certainly, you can eat the leaves but you might find them a bit tough.

started 2 metre square gardens about 6 weeks ago. I have marigolds next to the broccoli and the broccoli is growing GREAT but is growing so fast it is putting my bush peas in shadow. is it ok to cut off a few of the broccoli leaves and if so can you use them in stir fry, or is it straight to the compost? thanks

Kate - Vegetables prefer deep pots, they need room to develop a good root system Wine barrels cut in half are great, large terra cotta pots will absorb water whereas large plastic pots are good. Only plant miniature broccoli. Plant the broccolis one plant per pot so they don't crowd. Because they are slow growing, pop in some quick growing lettuces in between as a filler. Vegies that do well in pots are tomatoes green leafy vegetables such as lettuce, salad greens, rocket and parsley herbs such as thyme, oregano and sage snow peas (remember to use a climbing frame) potatoes beans, eggplants,spinach, silver beet and chillies

I was so excited to use the egg shells and get rid of the green catapillar. Now, welcome the grey aphid! After much research I have found that native Aust. ladybirds and lacewings do the trick. After even MORE research I've found where to buy them: (I cannot post a web link) bugs for bugs (dot com, dot au)
