My Mulberry tree is about 20 years old. After about 5 years it fruited well. For the last four years, lots of mulberries have formed but most of them fall off, leaving only a very small amount of fruit which form properly. Can you help please?
The most common reason for mulberry trees to prematurely drop fruit is stress, especially if there's been a drought. They need plenty of water to fruit well. You may also want to check the tree for signs of insect pests.
