Reviews from gardeners about the Black Diamond apple tree
Good afternoon.
We are very sorry. Unfortunately, in recent years, unscrupulous sellers are no longer uncommon. Therefore, we always recommend (and write about this in articles) that you buy seedlings only from trusted sellers. And even better - in nurseries.
We can assume that, most likely, Black Diamond cuttings were grafted onto wild animals. Or is it just some kind of decorative variety, very similar in appearance to Diamond.Or the variety is not zoned. There can be many reasons. The important thing is that, alas, it is no longer possible to change the size of apples.
Seedlings are not a product that can be valued in a short time. In the best case, they begin to bear fruit 4-5 years after planting, and, alas, there is no one to express dissatisfaction at this time. And scammers actively take advantage of this.
There are serious discrepancies in your case. According to the description of the Black Diamond apple tree, fruiting of this variety begins at 8-10 years. And you write that your apple trees began to bear fruit in the 4th year.
Hello, please tell me. I planted this tree about four years ago. Yes, it’s very beautiful, the leaves and flowers are all just classy, but the apples on it are the size of a thumbnail. I don’t understand why. I live in Crimea and he gets enough sun, the apples are really purple. But they are tiny. I’m already cursing myself and the sellers for deceiving me about the size of the apple. It’s just that if they said that it was decorative, I would still buy it. But I would have planted it somewhere else. And of course the tree is very beautiful. I just want big apples 🙁
