Hi There,
We have three 40 foot Sycamore Trees behind our house and they have covered our garden in leaves this year and everyone has very bad black spot / tar on them. My question is will this harm my exisiting plants? I have tried to get as many up as possible but some of my garden is a bit forest like so it's impossible to get them all. The garden mostly contains holly, yew, acers, conifers and low level ground cover evergreen plants.
Many thanks
