Hi, I was wondering whether anyone could tell me if it is normal for my Mop Top Robinia's leaves to turn yellow and fall off as I thought they were evergreen trees. I planted 2 Robinias about 6 weeks ago. One is OK so far, while the other is losing its leaves quite a lot. They have had plenty of rain water. I don't know why there are turning yellow Treena.
Suckers are little plants which grow from the main plant.
Robinias are very susceptable to suckering. There was another thread on the subject a little while back. Here is the link. I have a robinia but not a mop top. Its leaves turn yellow prior to falling in autumn.
