When I bought this sapling, I thought it was a cherry sapling. The merchant sent me a plum tree instead of a real one. I didn't know it was a plum tree when I first planted it. I didn't know it was a cherry tree until it produced four fruits at the beginning of the year. Just think that it's ok as long as it produces fruits, no matter what kind of tree it is.
Two fruits fell off when the fruits were almost ripe. My mother said that they were very fresh but very sour, probably because they were not fully ripe. I picked one yesterday, washed it and ate it. It was very sweet, like black plums, with dark red skin and yellow flesh. The skin was still a little sour, but you had to peel the skin and eat the flesh inside, which was very sweet. The taste was no different from the delicious ones bought outside.
I decided to keep this plum tree after seeing one fruit. It produced 4 fruits this year, and there will definitely be more next year.
