I planted in late May and now (early spring) the stems are 1-2 foot tall and small sprouts are forming but the tops are starting to flower. Should I leave them, pinch out the flowers or just pull out the whole plants?

If flowering the plant is coming to its end. Not enough fertiliser or the growing season is ending. It is a winter crop and for cool cold climates.

Hi what is the best fertiliser for my brussel sprouts in pots some say Tui Vegetable food but I am reading to avoid too much nitrogen as they are 30cm tall now. some say Tui Novatec premimum or blood and bone???? so confusing thanks very much kind regards Sarah

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"

Mo, Brussel tops are the leaves from the top of the B Sprout plants. In some places, the whole stem is cut and sold with sprouts and top. A google search shows recipes for using the tops. Spring greens are cabbages which are started just before winter and still small but usable in spring. You might have difficulty growing Brussel sprouts in a sub-tropical area as they prefer cold weather.

Hi Jo, the answers will appear in the same area. But sometimes it takes a while before they happen.
