Plant Brassicas in June & July


Brassicas are just perfect for being planted in mid June and July. Most will be ready to harvest in late autumn/early winter and many will over-winter too for harvesting in late winter/early spring. It’s always nice to have that slightly later crop available, and it’s nice to be able to plant out a little later in the summer while you’re waiting to harvest other veggies.

Essentially there are two seasons for planting brassicas – in early spring for harvest in autumn, or in mid-summer for harvesting in winter and early spring the following year. Many gardeners will plant their brassicas out in August (and you can plant kales and a couple of others in autumn too) but by getting them in the ground in mid-June/July you’ll give them a really good head start before autumn arrives (which, given the year so far, could be at any time – you just never know these days!) and growth slows down.

If you are planting brassicas in the next few weeks we have a few words of wisdom for you:

  1. Protect them from pigeons who are notorious for nibbling at brassica leaves when nobody’s looking! A net or light horticultural fleece will do the job.
  2. Protect them from cabbage white butterflies who will jump at the chance to lay their eggs on your brassica plants. Again, light horticultural fleece will do the trick.
  3. Put a brassica collar around the base of the stem to protect from cabbage root fly. Simply cut a 10cm disc out of cardboard, cut a slit into the middle (and a couple of extra small 1cm slits at the centre to give the stem a bit of space) and place it around the stem. This will stop the larvae of the cabbage root fly from burying into the roots of your brassicas.

Happy growing!
