Q.Fruitless mulberry tree
I have a one year old Fruitless mulberry tree. It is almost June and there is no foliage yet in the tree. Is it still early, when will they develop leaves, or is there a problem with my tree?
You can bend the branches of the young tree. If they bend without breaking they are still alive. If they snap off, they have died.
You can also scratch the bark. If you see green underneath, the tree is still alive.
Even late leafing trees should be showing signs of life by now. Your tree may not have survived the winter.
Most garden centers guarantee a new tree for the first year, so you may want to contact the grower for a replacement.
Here are some articles with more information.
