I've talked to a lot of people who often have bugs and worms get into their leafy greens. That is part of the reason that I have avoided trying to grow them myself up to this point. That stinks that they just can't mind their own business and leave your stuff alone!
The biggest problem was the mustard greens had grown quite tall and was a perfect breeding ground for laying eggs. I'll have to reconsider whether I grow them again next year. I do like my greens though 😔
There is something quite special and tasty about greens!
