My fiancée and I bought our first house last December and the previous owners did a fantastic job with the garden. Beautiful plants, shrubs etc, and a small pond (estimate about 2m x 1m and 2m deep). Up until a few weeks ago the water was fairly clear with a few lilies. I noticed we had frogs (I counted 8) and they produced frog spawn which has since given birth to lots of tadpoles, although I haven't seen them.
The problem now is that we've suddenly hit summer and duckweed has blanketed the pond. I would like to manage the duckweed as I know it's hard to get rid of completely, but I'm not sure if I'll be harming the tadpoles and frogs if I remove it as they might like it?
I have absolutely no idea, its the first time I've had a garden with grass let alone an ecosystem! So any advice would be really appreciated.
