We took advantage of the natural rock face at the front of our lot and added a small pond garden. We've thoroughly enjoyed it this summer: water lily bloom, water primula and the fish went forth and multiplied. A medium sized koi and many smaller ones who became so tame it was part of our day to walk past here and be greeted by them. Then, last weekend: the whole thing trashed. Bullrushes broken, bent and smashed. Plants all over the place. 3/4 fish gone. I did some internet searching and we implemented two things that seem to be working: a length of drainpipe in the bottom of the pond (refuge for the remaining fish who are so traumatized we rarely see them now) and two 150 watt motion-sensor spotlights. So far so good but I'm thinking the wildlife that did this might get used to the lights. Anyone experienced this? What worked/didn't? Rather than put net and chickenwire I would fill it in and plant a garden (yikes, unthinkable). All comments welcome! and thank you. p.s. does anyone know if a deer fence keeps the raccoons away? We're putting one up this week and plan to cover it with climbing roses.
