Research an organic spray for white fly. Or a chemical one.

Hi My Brussel sprouts were growing really well and now with the buds forming they are all loose and floppy. Is there something that I can do to stop that? Thanks in advance.

Would`nt even bother to grow these Again .. grew in trays .. Put some in pots ( Big fail, due to the very large root system) some in the garden very healthy.. takes up a lot of room, takes way to long to grow in a small garden.. all it did was keep the slugs happy , shaded out, every other growing vegetables.. Lost my patience.. and ripped them all out..6 months from seed to harvest is too long. cheaper just to buy in the store in season

A couple of points. Plant tall plants in the southern end of your garden (then they don't shade other plants). The sun crosses approx over head E to W in the summer and in the north in winter NE to NW.

Can I plant Brussels sprouts in September

It says Jan - March. The reason, most vegetables are seasonal, so you need to plant in the right season.

Grew brussel sprouts for the first time in Blenheim. Was impressed with the size of the plants. But, when I took the sprouts off they were full of a white powdery substance. When I shook the plants, white fly came off them. Is there any hope for my sprouts? Some of them are still developing .
