I've had a mulberry tree in front of the house for several years, it was growing along with hibiscus and never did much other than get cut back frequently. This fall, I removed all the hibiscus, didn't cut the mulberry back. I figured I had a sterile tree, so I bought a seedling of another type of Mulberry and put it about 3 feet away.
Well, the tree fruited, like crazy! And they are delicious, I haven't had fresh mulberry in years, since I was in SE Asia. Wondering why we never see the fresh fruit in stores? I imagine it has a pretty short shelf life and is pretty delicate. They are a great little treat, going to get the ladder out tomorrow to harvest the stuff up high.
