tiny Valkyrie asked: I just planted a hybrid elm tree (dutch elm disease resistant) in my yard, and I noticed some of the leaves have brown splotches and are turning yellow.
I also have some bug munching the leaves, but the brown spots concern me more.
What could this be, and what can I use to clear it up?
I do organic gardening and would prefer a non-chemical solution for this, but whatever works will be fine right now.
