Greasy Spot on Lemon Tree

Anonymous added on March 14, 2014 | Answered

My lemon tree has "Greasy Spot" fungus. It's not very bad yet. It's full of blooms and small fruit. Some sources say to spray with liquid copper in June. Why June? Shouldn't I spray now before it gets too bad?

Yes, June to late July are the recommended times to spray, though you can also begin treatment as early as mid-May. Here is more information: https://www.gardeningknowhow.com/edible/fruits/citrus/greasy-spot-fungus.htm
