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

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?

Please tell me whereI can purchase dwarf Brussels Sprout plants in Idaho. If not available, where can I purchase seeds. Thank you, Jaci wilkins

The cabbage like top of the Brussel Sprout is the best part. If you get a good frost on them the sprouts will be nice and tight so don't shelter or protect them from the frost.

Hi I am from melbourne. I put the seeds in the mid of March and they are 1 meter tall now but no sprouts yet. Tiny balls appear between the nodes and with few days they flower up. Its been 8 months now. Please suggest what to be done

planting time for Brussels sprouts depends on the variety and can be as early as Oct-Nov and as late as Feb. Good seed providers should state what month they should be planted. Look up an old book - Vegetable gardening in Australia by Norman de vaus. He has good advice and a good understanding of how to grow brussels sprouts. Finally some of the seed you are buying may not be well selected and may never give good spouts no matter what you do. Hybrid seed is one option if you are sick of failing at Brussels sprouts.

Trying to understand when to plant my brussels sprout seeds in Zona 10a. It says about P = sow seeds in Oct. Is that meaning to sow seeds directly in my garden? Because after that is says to start seeds in trays and plant out 4 - 6 weeks. Should I start them in seed trays and if so do I plant now so they can be transplanted in my garden in Oct or do I wait until Oct and just plant the seeds directly in my garden? Sorry the info is confusing.
