Protecting Monarchs from predators.
I was admiring the beautiful rearing cages on another thread, and wondering whether it would work to put one of those cages over a milkweed plant that is already growing in the ground. Would spiders crawl under the edge and cause havoc? I should probably try a sleeve that can be tied around the bottom. I remember how much time it takes to open and clean cages indoors. And the milkweed leaves don't stay as fresh as they would on the growing plant. It always seems like a waste to throw out leaves only half eaten.
I tried to sprout seedlings in pots that would fit into a cage, but I had dismal germination. Maybe I can scout around the outdoor plants for some volunteer seedlings. Except I was hoping those would attract the females to lay eggs. Oh, it's so complicated!! LOL.
