I am trying to determine if I need to dig this tree out or give it time. From what I can find, I think it has verticillium wilt. The tree is a Basswood/Linden planted 3 years ago by the builder. Trunk looks normal and I do not see any bugs. Leaves did not have anything on them that I could see just turned yellow, brown and fell off. Started on one side and mostly gone in a week. The first picture was a week ago. Tree was full of green leaves. A couple days later is the picture with yellow leaves and a few days later the first picture. The twigs do not seem brittle or snap off so it is still alive. The bottom had a large circle of dirt with some mulch with an open area around the trunk. I have removed all the mulch now. I have irrigation that waters every other day. Please let me know your thoughts.

What are mulch options ..mainly for moisture retention purpose,,,,?

What is happening to my three pepper plants? See pictures of brown spots & leaves are dying. They are three different types. This seemed to start as soon as it got hot... Do I throw these away and plant new ones??

We are new to South Dakota from northwest Minnesota. We live on the outskirts of Wall. The land around our house was once a horse pasture, clay. How can we make this soil better for vegetable and flower gardening?

I have been growing various lilis for year with no issues, but this year I have one with two stocks and all the flower buds died early on. Any ideas about what may have caused this. Thanks
