Some cabbages form hearts (a dense cluster of leaves in the middle) which tend to be sweeter than the outer leaves
So far we have avoided problems with white cabbage caterpillars but yesterday there was an army of them flying all over the place…we will need to be vigilant from now on! I think leaving the broccoli and kale to seed and flower in April and May before removing them has helped so far
The first wave of butterflies had laid their eggs on those plants and then as I removed them, I managed to disrupt the breeding season by a few weeks, before another wave arrived!
There isn’t enough evidence to say for sure but I’m going to see if the same happens again next year
