How bad is the damage? It is big enough to do a partial harvest? If so do it, that will let in more light and air to the bed and discourage the critters. You can also do some succession planting so you will get a harvest. You can plant into fall with spinach and many of those type of crops. It like broccoli, cauliflower and carrots do better with a nip of frost and will grow for you most of the winter without the bugs...:)
The damage is so sever that I had one seedling left yesterday. Today I went out and that seedling was gone. I did do a succesive planting about a week or two ago so they should start coming up. I thought Spinach would bolt if it gets to warm. I got my Cabbage started in a flat and will be putting it out come March. Carrots are in the ground and doing fine. Only two problems with the Carrots their overcrowed and occasional bermuda grass comining up in the patch. I'll try this fall for some other stuff.
Hmm, that doesn't sound like pill bugs...maybe bunnies. They will take it all. Buy yourself the cheapest bottle of Cayenne pepper you can find and sprinkle it heavily all over those things. That will discourage any bunnies. They don't like hot stuff! Yes, spinach will bolt if it gets too warm. That's why I suggest inter planting it under other plants that grow taller and can offer it some shade.
Hmm, this is a puzzlement. Let me think on it a bit. Do you see any tracks around your bed at all? Unless you do have slugs, they'll gulp it down, but pill bugs couldn't do that kind of damage that fast. I'm still leaning to bunnies even though you may have not seen them,.
Yes, I've seen tracks in my beds, but I assumed they were cats. Why is it nothing else gets chewed down? I have also noticed a couple of pea seedlings bit down. Their stem was remaning. Their planted in the same bed. In that bed I had at liberal amounts of Coffee grounds. I don't know if that makes a difference.
