Here are a couple debris clumps taken in early morning light.  To the right in heavy shade are the 14 caged positions as they were last year, albeit with somewhat different buffer and companion plants.  We’ll get more into that later.  Due to the rain the debris clumps, clumps of old planter matter and mix have maintained their green.  Some have mint and chives growing.  If I see a tree I’ll pull it before the roots try and penetrate the rubber roofing.  For the most part the rest of the plants that grow in these are harmless.  I typically don’t water them nor do I seed them.  When dry they can be kicked around the roof like a hockey puck.
