Apparently this has been going on for several years (judging by the regular oak seedling crops) but until recently it hasn't really been a problem.
There is a squirrel (or more than one?) burying acorns in my planters on the roof!! My husband finally actually caught one doing it a few weeks ago. I know s/he's still at it because I'm finding my plants half-uprooted!
Magellan's sun-window overlooks the roof, but he doesn't guard 24/7. I know some of you have had crazy pest problems on your balconies... does anyone know a squirrel-retardant mulch or something similar?
Thanks in advance.
