Just joined the web site this morning. I have a question regarding the benefits or detriment of trees planted around a pond. We just moved to a farm with an existing spring fed pond. Lots of black walnuts on one side. A pond guy told us they all have to go - something about sending roots towards the water and messing up the bank. Is this true? and are there any trees we could pant where this would not be a concern. I believe there are some maples too. anyway - seems a shame to slash and burn it all. Thanks!
