My cherry tree is almost ready for picking! Does anyone have any ideas for keeping the birds away? The cherries are a bright red colour right now They will be ready when they turn a deeper colour of red, slightly purple They are sour to the taste when they are not ripe enough This is when the birds like to raid the tree, they cause a lot of destruction as well as eating them. This is my cherry tree! It is about 40 years old. It is approximately Fifty feet high and 25 feet wide. It's a backyard tree, not like the orchards where they are much smaller.
