Hi Kate, You might like to try spraying Dipel - its a bacteria mixed with water that kills the caterpillars but is safe for humans, pets etc. or another remedy that I heard from Penny Woodward on 3CR Garden show last Sunday morning (an excellent radio gardening show on from 7.30am to 9.15am on 855am in Melbourne) was 2 Tablespoon of Molasses dissolved in 1 L of warm water and spray that on. We tried it with Carob Molasses this week and the new leaves on one of the broccoli have less holes than the old leaves. I also try to remove the caterpillars from the leaves or brush off any eggs you can see.

Any tips on what broccoli types produce multiple heads? What I've looked into so far at Bunnings have been single head broccoli plants.

Broccoli De Cicco. Diggers Club sells them in Dromana or online. Bunnings now stocks alot of Diggers products. I grew some last year from seed and couldn't keep up with the growth.

My broccoli plants are getting consumed by those white moths at the moment. Any ideas on how to stop this attack? I have pets so don't want something that may harm them. Thanks.

Kate I use Yates vegetable dust to control insects, as well as pyrethrum in my vegetable garden Pyrethrum is also good for control of pests in cycads, roses and other ordimental plants

I use a solution of garlic & chilli peppers and spray on the plants. cut 5 cloves up in small pieces add heaps of chillies to a two litre container of water. Let it sit for four or five days. Strain and pour into a spray bottle. Spray all over the plant and roots I sometimes reuse the mix two or three times until the mixture is impotent. I always have at least 2 bottles ready to go. Careful NOT to get any solution on you. It reeks!
