I have used, for the first time, garden domes from the ware house. At last I don't have to spray for white butterfly. The domes let nothing in due to the mesh size. Bees can get in but find it hard to get out. So I now have four of these domes. Snails, birds, you name it. Nothing can get in.

Are there recommendations for sowing cabbage seeds that are tolerant of hot days (17 to 21 deg C and cooler nights 6 to 10 deg C as experienced in the central N.I. I do OK with shop bought punnets in early spring and mid to late autumn, but have no luck with sucessional planting in late spring through summer and early autumn.

Cabbage are a cool weather crop not a hot weather crop.

If planted 1st DEC then they are about 12 weeks old. It says 11-15 weeks. It would depend what kind of cabbage you planted. A small kind or large variety. I grew red cabbage that are suppose to grow to 2-3kg but only grew to the size of small rock melon. You need some nitrogen fertiliser. N is for leaf growth, P for root development and K is for flowering and fruit growth. You should apply these before you plant generally. Too much N and you will have too much leaf. A handful of general fertiliser will cover about 1 square meter. Or place about 2 tablespoons of general fertiliser in 9 l of water and let it sit for a few hours, give a good stir and apply to the plants. It may be a bit late to do too much with your cabbage. Give it a go though.
