|I have a non-flowering Weeping Mulberry tree in my backyard. I prune it to look like an umbrella and I love the look of that but I have a problem with black spots on the leaves every July and by August the leaves start turning yellow and fall off. I have sprayed it with a fungicide but this does not seem to help much. Do you have any other suggestions before I give up and remove the tree? Thanks|
|Mulberry leaf spot is caused by a type of fungi that attacks the leaves of the tree. Fruitless mulberry trees are particularly susceptible to it. Mulberry leaf spot can be identified by the leaves growing somewhat malformed, yellowed and having black spots. Fungicide sprays are your best defense against the spots so perhaps you did not treat your tree early enough in the season (fungicides protect leaves if applied as soon as the leaves unfurl - repeat sprays may be required so be sure to follow directions on the package).
It's important to remember that you will need to clean up and dispose of all the fallen leaves in the fall or winter. The mulberry leaf spot fungi over winter on the fallen leaves and in the spring, the rain will splash the fungi back onto the tree, which re-infects it for the next year. Removing and destroying the fallen leaves will help prevent this.
Hope this information helps!
