The planters are open at the bottom. I once grew a parsnip in one and the root went down past the planter bottom! I've refilled one of them twice now, putting cardboard at the bottom, but I keep getting couch grass coming through, which is frustrating. It's very persistent as that's a lot of soil to get through!

The apricot is fully enclosed in one of the chicken runs. I used to net it before they were built, but some of the birds would still sneak in! Last year rats got them all. There's always something, isn't there!
