Leaves dropping off cherry tree prematurely
Last year I planted a cherry tree in June. The leaves developed brown spots and shriveled and died. This happened in early September. This year it has buds. Is there something I should do to prevent a recurrence? Sorry. I can’t find the photos I took.

Yes, cleaning up around the tree is important. Pick up fallen leaves and keep the area clean as the fungus can overwinter in the leaf debris. Fertilize, best time being right after flowering, and make sure the tree stays properly hydrated throughout the season. Keeping the tree healthy to begin with allows increased energy for it to help defend itself against a host of pests and diseases.
Not always enough however and a preventive fungicide spray routine may be needed when infected with a fungus, one of which is cherry leaf spot. Timing is important, to happen at budbreak and again two weeks later, but too late for that now.
