Pond Boss Forums INTRO Questions & Observations Black Walnut Trees near a pond

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.

Tim W,

Since no one with experience has answered, here is an answer from someone with limited experience with Walnuts.

In Missouri, where I grew up, we would never have a garden anywhere near a walnut tree...because of the reasons you mentioned. It stands to reason to me, that the same logic would apply to ponds.

Having said that, I wish I could grow them in Texas...I love the trees....but not around a pond.

Further, you do not want any trees in your pond's dam....none. They cause structural damage over time and leaks and big problems.
