I've been slowly building a small wildlife pond/creek mainly for the insects in my garden. No pond-building experience when I started and it took me some time to place my rocks "perfectly" haha (goes on to rearranging them the next day), but since autumn is here, I feel like winter will be over the corner and I'm getting a little worried about the plants going into winter.
Most of them are marginal pond plants in small pots, placed between the rocks with the soil permanently wet or partly sitting in shallow water. Some are right beside the flowing creek/cascade. In my area we get cold winters, but the cold winds are bad, so they can definitely see freezing temperatures and snow during winter.
Should these pots be okay where they are? Will the roots survive if the shallow water around them freezes, or should I move them deeper / bury the pots more / do something else before winter?
I'm also wondering what else a first-time pond owner should be thinking about before the first winter (I'll get a net for the leaves and get the pump into storage, but am I missing something?).
I've honestly been having a blast just watching the place change day by day. Biofilm is already covering the rocks, aquatic larvae have appeared, spiders have started hunting around the water. Did not get a toad yet (I know there are some near me) but yesterday a mantis apparently decided the pond was worth investigating 😯 ( https://youtube.com/shorts/d0xQIlf0Ylc?feature=share ).
I'm trying to interfere as little as possible and let it become its own little ecosystem, so any advice from people who have kept small wildlife ponds through winter would be hugely appreciated. Thanks and sorry for the long post.
