Most apple varieties can self-pollinate, but the seed setting rate is relatively low. In order to promote better and more fruits, it is best to artificially pollinate apple trees at flowering stage. Choose a soft brush or a small brush, first stick the pollen on the stamens, and then coat it on the pistil, so that the yield of apple trees will be higher.
The optimum temperature for apple planting is about 25 degrees, which is not suitable for planting apples in high temperature areas. Secondly, it is rainy in the south and the sunshine is seriously insufficient. In this respect, the south is no more suitable for growing apples than the north for growing oranges.
In a word, apple trees only blossom but do not bear fruit, which is related to pollination, climate and environment, long-term non-pruning and non-application of pesticides. In order to achieve results, we need to start from these aspects.
