Hello there. I just bought a Corylus avellana contorta and I have planted it.. however I have noticed that it has a very straight shoot coming from the ground next to main stem/ trunk .. it has the same leaves but is very straight.. do I need to cut it off ? Many thanks Joana
Yes, those are suckers form the root and they will take over your tree, eventually. You will want to cut them off.
Here is an article for more information:
I have a walking stick that I planted a little more than a year ago (2 ft high). It has been doing well, but suddenly several leaves have started turning brown at the edges. I live in MD and the last two weeks have seen hot and humid weather with lots of rain. Would appreciate any advice
While they do appreciate regular watering, this sudden deluge is probably to blame. You may want to treat it with a fungicide although they work better as a preventative than as treatment.
I would remove some of the affected leaves and discard in the trash. Check the stems for signs of canker as mentioned below.
