|About 95% of all fruits on my plumb tree became rotten while still green and on the tree. As the result, all fell to the ground and there will be nothing to eat. What could have caused this and how this is going to affect future crops?

|Sounds like the disease called brown rot. It's a fungus and in order to keep it from developing you need to spray your plum tree with a fungicide in the spring time. For now about all you can do is rake and remove the fallen fruit to get rid of the fungal spores. Be sure to rake the fallen leaves, too. Early next spring put your plum tree on a spray program to protect the leaves and fruit. Use Daconil or lime/sulfur and follow the directions on the label. You'll need to spray several times at specific intervals to protect your tree from developing the disease next summer.
