Some of the leaves on my 2-year-old Thompson Seedless grapes have started to curl at harvest.

We planted what we thought was a lime tree around 10 years ago. Now we have a 20-foot-tall, nicely shaped tree bearing an unknown fruit.

Recently, one of my walls of star jasmine has been struggling with dry and dull green leaves.

They were in bloom when we planted them five or six years ago, and they bloomed the following year as well. But they have not bloomed again.
