Too bad you have to go through all that, Hive account@simplymike. I understand you perfectly, I also suffer when I see my plants attacked by worms and vermin. It must be a ground problem, try to have pots, but don't say goodbye to the garden. I share with you that it is an oasis that calms and gives peace.
These days I discovered a worm that ended up with a fern that was green and healthy. It practically ruined it, today I was just taking away the dry leaves and the sticks that it left peeled. It is frustrating when you love plants, you take care of them daily and in an instant they disappear due to factors of any kind. A hug for you.
