I always collect my broccoli seeds for replanting. The pods needs to be very dry or they will have black mould. Hold a bowl under the branches with the pods, crunch them in your hand and collect the seeds. I plant my boccoli a few inches apart, let them compete with each other, and pick the "broccolini" as they appear. The plants can continue to produce for five months. Even if the broccolini is trying to flower it can be picked and cooked. Put a nob of butter in a saucepan, fill with broccolini, cook slowly with the lid on, stirring occasionally so they don't stick. They will be dark green with strong flavour. My favourite vegetable.

Some broccolini I purchased has gone to seed and I was wondering if it would grow if I planted it? Could you please advise the method? Thankyou.

Stan: Broccoli is very forgiving and grows very quickly when given plenty of high nitrogen food such as sheep manure. I always sprinkle a tiny amount of trace elements each time I add a new layer or 'stuff' to my raised beds (say once a year). To hurry them along, especially if your weather has turned cold or your planted late as I did, liquid fertalize every 3 weeks with Harvest or other organic liquid fert.

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.
