'Black spot' or not...
This is a really beginner question; I hope you'll forgive my ignorance. We just bought a new house and when I was looking over the grounds I noticed that 3 of the bushes in 2 different areas have black spots on their leaves, and some of the limbs seem not to be very healthy (wrong color, fewer leaves, occasionally just a bare branch).
My question is, is it possible these are just varieties of bushes that have speckled leaves and the unhealthy parts are just nature and age? Or are spots always a sign of trouble.
And then, what to do? I would really like to not put chemicals in my yard if possible, and money is tight for the moment, so something I could put together at home would be perfect.
Thanks in advance,
