Is there such a thing? The little bridge over my pond is made of cedar and

Is there anything I can use that won't poison the fish and kill the plants?

How often do your fish use this bridge?

The preservatives that use Copper Naphthenate are the safest for plants.
One popular one is Cuprinol. It can be found as Sherwin-Williams
Company Cuprinol Wood Preservative, Green No. 10
