Kale and cabbage problems
Earlier this year we started to grow various types of kale and cabbages but when we started to harvest them, they are covered in the insects as shown above. We noticed over the weeks that many of our green vegetables have been eaten so we used organic slug pellets regularly and we have a net frame over them for protection from butterflies etc. Can anyone please advise what these insects are and what we can do to eradicate them in future. We assume it’s too late to do anything with our current batch - we can only use a few leaves that have fortunately not been attacked - and this is a very disappointing attempt to grow our own veg but are still keen to grow them again.
