The only way to grow Brussels Sprouts is under fine mesh netting. This keeps off all the bugs and is true for all brassicas. Just drape the mesh over the crops and anchor the sides with stones or pegs. You will be amazed at how good your crops are. Mulch heavily so you don't need to remove the mesh to weed. You can buy this mesh at Mitre 10, it's called "quarantine mesh"

Hi fellow gardeners. I'm not having much luck with any normal seeds. I think I am going to source Heritage seeds. Perhaps I'll have better luck. Happy New Year & Happy Gardening. Tina

I'm in northern Tasmania and planted my Brussel sprouts in May as well. The whole lot went to seed after producing a few very loose sprouts. I though a pout using the leaves in soups etc as I hate waste, but I read that they are quite bitter so I guess the lot go into compost. Any comments welcome

If you still have some going to seed, let them, and then collect the ripe seed for sowing later.

I had the same experience, Kay, but I did harvest the plant on the weekend and made a delicious soup with the leaves. I put the hard stems in the compost. The base stock for the recipe was one diced onion and six cloves of garlic chopped and softened in olive oil, 2 litres of chicken stock, 1 cup of white wine, 1 cup of water, salt and white pepper. Add the leaves and 250g of mushrooms and simmer away for an hour or so then blitz with a hand blender. I also added half a cup of cream at the end. It was really delicious and the left overs went into the freezer!

Hi! When it says "S" it means start seeds inside, when it says "T" it means to transplant those seedlings outside in the garden. When it says "P" for plant outside does that mean you plant the seeds outside? I'm unsure because, take Brussels Sprouts for example - It says "S" in March and "P" in May and June; what is the "P" referring to? I'm just confused because some vegetables have an "S" and a "T". Thanks for any help you can give me!!! "Plant in garden" means to sow seed directly into the garden where you want the plant to grow.

Something has eaten all the leaves on our Brussel sprout plants. Will they still grow?

The guide here says plants seeds in March and plant out in May. Most veggies need plenty of sun.
