There is a linden tree in the yard that has been dropping leaves early. The leaves look like they have some black marks on them. Does this look like gall mite? Not really sure what is going on with the tree.

Transplanting sedum #885340

Asked September 15, 2024, 6:58 PM EDT

Hi I have a whole lot of sedum that I need to divide and share. My question is if I cut it back and then divide it and replant the Roots/base only will it be successful? In the past I've always just split it in the fall when the entire plant is blooming and left it that way. Occurs to me it would be easier to work with/transport if I cut it back first.

Wet soil #885338

Asked September 15, 2024, 6:40 PM EDT

I recently had some landscaping done, removing weeds with heavy machinery. They added top soil which is absorbing a lot of water. In fact, my feet are sinking a few inches into the soil. What amendments would I add to make it more suitable for planting? How would these amendments impact the soil ph? Thank you.

Lilac browning #885330

Asked September 15, 2024, 5:34 PM EDT

Hi there, my lilac bush has been browning over the past couple of weeks. The stems are still green on the inside, despite the leaves turning brown. Seems to be working its way up the bush. This seems very early for my lilac to be losing its leaves although this is the first fall I’ve experienced with it as we recently moved. The lilac bush next to it seems mostly unaffected.
