We need a visual screen for our neighbors, but I don't want to cause trouble with there pool. They have a nice pretty suburban house, whilst ours is rather more rustic, with firewood logs getting cut up, tractors, etc.
Their pool is about 9m (60') from the fenceline where I'll plant new trees. Prevailing winds will mostly miss there pool with whatever the trees drop, but no doubt some stuff will wind up in there pool sometimes. So I'd like to choose trees that are not known for causing trouble with pool chemistry, as our neighbors are relative neophytes and rely heavily on (go ahead and groan) a pool store guy who smokes and throws his butts.
I'm thinking conifers so no leaves will leave. We live in France near Germany. So if anybody has a recommendation from your similar climate, please fire away! The last thread on this topic that I found in search is a year old, and did not address the use of conifers in my climate.
