Re: Gardening Thread
Our pond hasn't got a pump, they're not necessary if its just for wildlife. If you're keeping fish then its another matter, as a build up of gases under prolonged icing over can lead to fish losses.
I dug ours out in 2014. Within a day or two a frog had appeared, we now have a healthy population of them. If you build some open compost heaps, basically just chuck your garden clippings in a quiet corner and let it decay. That's all frogs (and toads/newts too) need to overwinter. Some will do that at the bottom of the pond, usually males.
I opted for no fish as they can decimate young tadpoles. But you get rewarded with tiny baby frogs emerging come late summer. Dragonfly nymphs too. The design I used has shallow outer ledges, only 4 or 5 inches deep. I stand bog plants on this like marsh marigold and devil's-bit scabious. We have a lily in the deepest part which is about 2ft. Yellow flag irises are very pretty but will take over the pond if not careful. The solid mass of roots is hard work to pull out.
