Why does our plants only produce really small main heads of broccoli, the plants appear to be really healthy.

It may be a small headed variety. Many of the large headed varieties are only available from commercial seed growers Contact Egmont Seeds (NZ) they have larger headed varieties.

I bought seedlings that said they were Kale from Spar here in Centurion. So now its 31st Jan and they are as big as small bushes about 1.5 metres and certainly not Kale but obviously Broccoli. No heads yet although 5 months growing. Should i wait for cooler weather for them to head or is it better to pull em out because there will be no cool nights until end Feb.

Why should broccoli not be planted in the same bed as capsicum? Too late for me this time, although both seem to be doing well.

We just bought broccoli seedlings from our local hardware's nursery, but your info says plant in spring or autumn. Should we return them or is there somewhere they might grow, under the back patio in a pot with winter sun on them perhaps? Please help.

Broccoli need cold to grow. Put them in the coldest spot in the garden. My broccoli is already going to flower but as flowers are edible i dont mind. You may find that you get very little from them this late in the season. Try approx 4 hrs of sunlight per day then the coldest part of garden for the rest of the day. Broccolini might be a better choice this time of year as you pick much earlier.

Javed, in Australia Broccoli grows best during the cooler months, it can be grown over summer here but tends to bolt and go to seed quicker in summer, I plant it in early to mid Autumn, it just depends on the climate where you live
