We have a plum tree in our front your. It gets plenty of sunshine along with water. We have lived here for about 2 years, and it seems to be getting worse. The tree is probably 6 years old and only 5 feet tall. Its leaves continually curl upward. Many of the branches only have new growth on the ends. It seems as though only one limb is actually doing well. We live in Nebraska, so we experience many different temps. I know very little about trees, so any suggestion would be helpful. I have found nothing online. I don't seem to have any insects or aphids, and the bark on the trunk also seems to be peeling. I'm considering pulling it up and starting with something new. It looks terrible. jchikos
