I'm also in Victoria and found that cabbage moths were laying their eggs all over my cauliflower and broccoli. I found a great product called Dipel (Yates) which is basically a natural bacteria that rots the insides of the moth larvae yet is completely harmless to all other creatures. It's free of pesticides and can still be used by certified organic farmers as it contains no chemicals. I found it to be very effective

Hi to all, a remedy for snails/slugs, sprinkle some sawdust around your garden ( if rain-repeat ) You can eradacate ( caterpillars & other pests ) using PYRETHRUM ( read directions thoroughly ) kills pests in minutes and has a WHP ( with holding period ) of 1 day. Yates SUCCESS is similar & controls a lot of pests. Can be harmfull to BEES ( don't spray flowers EG zucc/squash etc ) Has WHP of 3 days & up to 14 on some fruits. Contains SPINOSAD as in tomatoe dust.

Do possums eat broccoli. Because something has eaten the vegetable in the early stages of growth and can I do about this & not touch the leaves.

Possums will eat anything that humans eat. In other words, possums have a very healthy diet.

I have Baby Broccoli and B Cauli, and Broccoli in situ presently, all doing well. I planted them about 8 - 10 weeks ago. There is no sign of them "heading up" yet, but they have become very leafy, depriving other veges of light/heat. Is one able to prune this leafy foliage without it affecting their progress, or should they simply be left alone?

Planted broccolini seedlings 6 weeks ago. There now have yellow flowers, so has the lot gone to seed before even producing any crop?

It sounds like it. Did they get a bit dry or hot at any time? that would push them into flowering.

I had the same problem with the winter broccoli this year and I was giving it to the chooks - only to discover when I read on the seed packet that with this type of broccoli you eat the head complete with flowers, and the stem. Sorry I can't remember which broccoli it was
