I was looking up companion plants for the cherry trees and I saw that mint, garlic, and rue will help discourage pests.
It's a little late in New Jersey to plant herbs, though I did put down a whole lot of garlic a few weeks ago.
I have one two year old cherry tree (single trunk, about 3' tall) and a bunch of first year cherry trees (fewer than 10") that seem to have stopped growing. They clearly have a disease (some leaves have brown stain spots, while others have wholes and such). There are no new leaves budding from the tops of the trees, and the trunks are turning a paler brown.
With some research, I found this:
The bacterial canker disease first appears as yellow and green leaves discoloring. These leaves then fall off the cherry tree to reveal weakened limbs. Often the cherry tree leaves drop prematurely, but in some regions the leaves may discolor, then brown and wilt. Eventually these leaves will wither and may even remain attached to the cherry tree throughout the winter if they do not drop from the cherry tree in the fall. The bark of the cherry tree has lesions on it which often ooze an amber to yellow colored gum from their centers. This oozing of bacterial gum is most common in the seasons of spring, fall and winter.
The site suggested that once fall hits the reach, to "spray the cherry tree with a basic copper containing fungicide which will help prevent additional infection and keep your cherry tree healthy."
This may sound like a stupid question, but I am guessing a copper containing fungicide
is not a natural product? Can I save these trees or should I rip them up and start new ones next year?
[In hindsight, I probably should have titled this thread "Issues with Fruit Trees" to open up possible discussions.]
