The phenomenon can be observed more and more frequently: while the fruits of the apple tree are just ripening, new flowers are already opening. But what causes this and does it harm the tree if it flowers twice a year?
Why does the apple tree bloom in September?
Due to anatural cause, theinhibition of the buds from sproutingis eliminated. The key stimulus can be, for example, warm, humid weather after a dry summer or a large loss of leaves. As a rule, however, the second blossom does not damage the tree.
How do flowers bloom in September?
Ifdue to an environmental influencetheinhibition of budsof the budswill open,they will open already in September.
The reasons for this can be:
- A strong pruning in the summer months.
- Hail that damaged most of the leaves.
- Continued drought, which is replaced by warm, humid weather.
- Extensive watering after a long dry period.
Is it harmful to the tree if it has a second M
As a ruleit doesn't harm the apple tree ifit blooms a second time in late summer or even winter. So just enjoy the flowers.
Cut off the small fruits if the size of the apple tree allows it. This will prevent the tree from putting a lot of energy into producing fruit that will no longer ripen anyway.
What explanation is there for the second bloom in September?
The apple treelays the budsfor flower formationin the previous year. By the end of the growing season, the tree produces inhibitors that… Prevent sprouting.
This inhibition of sprouting is reduced by the winter cold. The buds begin to swell in spring and the tree blooms. However, if this mechanism is disrupted by the environmental conditions described, some of the buds that have already been laid will open in the same year.
Tip
Cutting apple tree branches for St. Barbara's Day
Since apple trees have a rather low need for cold to open their flowers, they are well suited as Barbara branches. To do this, cut a few branches with noticeably thick, swelling buds that you would have had to remove anyway the next time you cut back the fruit tree.
