Does anybody know what effect black walnut trees would have on a small pond?
I know the leaves of the black walnut tree have a plant-growth inhibiting chemical in them. I've been told to never put them in my compost pile because the un-composted leaves will kill some plants (like tomatoes).
Would the Walnut leaves from a pond-side tree planting have a similair growth-inhibiting effect on water plant growth (both the desireable and undesireable growth)?
I'd love to know what expereince anyone else has had with "semi-toxic" plants growing near their pond actually influencing the pond itself.
