TREES IN FLOWER FOR THE SECOND TIME A YEAR
At the beginning of autumn, such an anomaly as the repeated flowering of fruit trees often occurs. True, it is not as plentiful as in spring - only single inflorescences bloom. Nevertheless, trees blooming in September cause gardeners to be wary. Various factors can provoke secondary flowering.
Let's name 5 reasons for this phenomenon.
1. Weather conditions
Sudden changes in temperature, cold or drought lead to a “hormonal failure” in trees. If the blooming flowers died during spring frosts, then dormant buds can bloom much later.
Dry summers can also cause trees to bloom again. If a drought occurs at the beginning of the season, development is delayed. Due to the lack of water in the soil, only a part of the flowers form ovaries.
Abnormally cold summers and warm autumns are also a kind of stress for plants, to which they can respond with the flowering of late buds (while the fruits will already ripen on the branches).
2. Diseases and pests
Due to the defeat of diseases and pests, the plant often sheds leaves early. There is a failure of the biological cycle, and the tree begins to bloom as if in spring.
3. Excess fertilizer
One of the reasons for autumn flowering is an excess of moisture and nitrogen fertilizers in the soil at the end of summer. Shoots do not ripen, the plant continues to grow and gives color. That is why experts annually remind amateur gardeners that nitrogen fertilizers cannot be applied from mid-July. During this period, only potassium-phosphorus (for example, ash) is allowed so that the tree has time to prepare for winter.
4. Mechanical damage
Factors such as strong or improper pruning, crown damage by wind, and breaks cannot pass without a trace for the tree. All this can cause thickening of the crown, late fruiting, protracted growth. The plant ripens incorrectly and, it happens, blooms out of season.
5. Wood aging
A weakened old plant rushes to finish its life cycle, throws out color to bear fruit for the last time
CARE RULES THAT WILL HELP YOU AVOID AUTUMN FLOWERING
In the spring during flowering, if there is a drought, water the plants. And vice versa: if it is cool in the second half of summer, exclude additional watering.
Timely carry out preventive treatments against diseases and pests.
Do not apply nitrogen fertilizers in the second half of summer.
Trim trees properly and in a timely manner. Remember: pruning promotes good development and timely fruiting, the plant can better withstand the load from the crop.
THE HAZARD OF RE-FLOWERING
Obviously, autumn flowering does not have the best effect on preparing plants for wintering. Trees do not store nutrients for winter, but begin to form ovaries. After abundant flowering in the fall next year, the plant may die altogether.
WHAT TO DO IF FLOWERS ARE ON THE WOOD
It is better to cut off the flowers in advance before they are fully blooming, so that the tree does not consume resources that are intended for next spring.
FACT: OBSERVATIONS SHOW THAT IN A WARM, BUT CLOUDY AUTUMN, FRUIT CROPS PRACTICALLY DO NOT HAVE RE-FLOWERING.
