Black plum spots

This tree is 4 to 5 yrs old. We are getting fruit for the first time but the fruit looked to have crystallized stiff sap. After a short time it started turning black. The pics below show it better than I can describe it.

Prevention of Thousand Cankers Disease in black walnut trees

Is there an insecticide or other treatment that I can apply to black walnut trees to prevent their dying from Thousand Cankers Disease (TCD)? We have half a dozen black walnut trees on our lot, and trees are being lost to TCD in the Knoxville, Tennessee area, according to our tree trimming service. Our trees have not been visibly affected yet, although they did appear to leaf out later than normal this year.

Mixed lawn

I live in Knoxville TN and have a residential lawn that is mostly fescue, but has Bermuda grass underneath. I like the mix of the two. But I have lots of clover and other broad leaf weeds. What is best to spray for woody weeds, sedges, and clover while not hurting the fescue and Bermuda?

Can I save a weeping Willow that fell in a wind storm

My weeping Willow tree fell due to high winds. We are thinking about relocating it on the property. If we do this, tips to help it survive... Or would it be better to relocate the root ball after cutting it to a stump. I live in southeast Tennessee. These trees grow well here and this one happens to be too close to the dam of the pond. It's probably 30' tall. I have the equipment to move it but lack the knowledge of keeping it standing and helping it live. Thank you
