Food and water is key now to ensure a bumper harvest
How are your brassica plants coming along? It's likely you've planted them out by now and are keeping an eye on them, particularly for signs of pest and disease. If you haven't planted them out, it's a little late but you can get away with it for a later crop. Once planted, water them especially well because they're thirsty plants and August can be a dry month.
If you're growing broccoli, manuring the ground before planting can mean it grows with all mouth and no trousers - that is, leaves galore but fewer spears! A little nitrogen-rich feed, such as liquid seaweed or Growmore, through summer can help as they grow, and every month after that give them a small boost to help them along. This goes for cauliflowers, cabbages and other leafy brassicas.
It's a waiting game for brassicas, though, as it'll be a good few months until any harvesting potential appears, but it's worth the effort for tasty, home-grown greens!
