Laburnum detritus in pond

Have just bought a Laburnum and thought it would look nice next to my pond. I later discovered that most parts of it are toxic and am now worried the seeds, dead leaves and flowers may infect my pond. Should I be concerned or am I worrying about nothing?

 

Yes I think you probably should be concerned, but I don't know that for sure. I think the seeds are the worst offenders - and certainly when we move our chicken coup about we keep it away form the Laburnum tree.

 

Trees can shed their leaves, pollen and berries into pond from a great distance especially if a pond is downwind from them. Laburnum and Yew have to be at the top of the danger list since every part of these trees including the pollen is poisonous. Alder Buckthorn too has poisonous leaves, bark and berries. Any tree that sheds any amount of leafage or berries into the pond is liable overload the biological filter system, but the leaves of willow contain salycilic acid – the basic ingredient of asprin, which is highly poisonous to fish. Oak leaves contain tannin, which in large volume can also be poisonous.
