Why don't cherry trees blossom and bear fruit?

Question 1: Why don't cherry trees blossom and bear fruit? What are the reasons and how to prevent them? There are many reasons for not hanging fruit, as follows: 1, probably because the climate is not suitable. 2. Improper cultivation management leads to excessive growth of trees, unformed flower buds and no fruit. 3. Serious pests and diseases or poor fertilizer and water conditions, insufficient nutrients stored in the tree, resulting in poor flower bud development and serious flower and fruit drop at flowering stage; Or because of continuous rainy weather or sudden low temperature in flowering period, pollination and fertilization are poor. The control measures are as follows: 1. It depends on whether the local area is suitable for growing cherries. Cherry can be divided into China cherry and European sweet cherry. Cherry in China has wide adaptability, while sweet cherry in Europe has relatively narrow adaptability, which requires strict climatic conditions, such as sufficient sunshine, less precipitation, large temperature difference between day and night, and sufficient low temperature in winter, otherwise it is difficult to form flowers, or flower buds are poorly differentiated and developed. 2, reasonable summer pruning. Young cherry trees are often difficult to bloom, so it is necessary to take reasonable pruning in summer. For example, from late May to early June, cut off the back branches or leave a pruning tip of 30 cm, and seal the incision with calluses anticorrosive film after pruning. Branches are pulled in July and August, the main branches are pulled to about 80 degrees, and the auxiliary branches and fruiting branches are pulled to more than 90 degrees, so as to control vegetative growth, promote flower bud differentiation and the formation of short fruit branches in flower clusters, and bear fruit early. 4. Keep flowers and fruits during flowering. Spraying Guaguozhuangdiling 1-2 times at the initial and full flowering stages, or 0.3% urea +0.3% borax +0.3% potassium dihydrogen phosphate 1-2 times; Or artificial pollination is carried out at the initial flowering stage and the full flowering stage respectively; Or, you can change the trunk of the tree and paint it with 1 to make the fruit trees blossom and bear fruit every year. Irrigation before flowering in low-temperature areas in early spring can delay flowering for 3-5 days and stagger low-temperature weather; Or spraying water during flowering can also reduce the influence of low temperature on flowering and fruit setting. 5. Strengthen pest control and fertilizer and water management. .

Question 2: Is this tree a cherry tree? Or what? It never blooms and bears fruit. 10 This tree is an ordinary cherry tree (China cherry).

An ungrafted cherry tree usually takes 4-5 years to begin to bear fruit.

Judging from the picture, if comprehensive management is strengthened this year (ensuring normal defoliation in autumn), it is expected to begin to bear fruit next year.

Question 3: Why don't cherry trees blossom and bear fruit? Maybe the time is not up to the temperature, the nutrition is not well managed, and all the branches and leaves have gone.

Question 4: Ask for help. What is the reason why cherry trees don't blossom and bear fruit? It is likely that this tree is not old enough.

Under normal circumstances, cherry trees can not begin to blossom and bear fruit until about 4 years after planting. If the tree does not bear fruit for more than 5 years, it is caused by improper management (pests and diseases are not prevented in time in summer and autumn, leaves fall off in advance or are eaten up by pests, the tree body is insufficient in storage nutrition, and the flower buds are poorly differentiated or undifferentiated, so it will not blossom and bear fruit).

Question 5: I have been planting cherry trees for the fourth year. Why don't I blossom? No results? This may not be a cherry, it may be a cherry blossom, or a late cherry blossom in Japan. Need to see what teeth and flowers are on the tip of the knife?

Question 6: How long does it take for cherry trees to blossom and bear fruit? Seedling raising method:

After the cherry is harvested, the peel and pulp are cut to take out the stone, and the pulp attached to the stone is washed away with clear water, and then the cherry is dried in the shade for 1 ~ 2 days before sowing. When sowing, the seeds are directly sown in shallow pots, and germinate about 10 ~ 30 days after sowing. When the seedlings grow to 5 ~ 250 px, transplant them into plastic soft pots. Cherry seeds are easy to germinate, but the germination is irregular. Some plants often lack viable embryos, and the germination rate is often lower than 30%. The fruit-bearing age of seedling-raising method is late, and it takes almost eight years to blossom and bear fruit.

Grafting method:

Grafting seedlings only takes two to three years.

Cherry habit:

Born on the sunny side of a hillside or beside a ditch, it is often cultivated, with an altitude of 300-600 meters. Cherry is a fruit tree that likes light, temperature, humidity and fat. It is suitable to grow under the climatic conditions of annual average temperature 10 ~ 12℃, annual precipitation of 600 ~ 700 mm, and annual sunshine hours of more than 2,600 ~ 2,800 hours ... The time when the daily average temperature is higher than 10℃ is150 ~ 200 d. If there is freezing damage in the local area, cherry orchard can choose the northwest slope where the temperature rises slowly and the air circulates in spring. Considering that the cherry root system is shallow and easy to be blown down by the wind, the garden should be in an area free from wind damage, and the soil is sandy loam with loose soil and deep soil layer.

Question 7: Cherry trees don't blossom or bear fruit! Big cherry should use grafted seedlings. The tillers sprouting from the roots of big trees are mostly rootstock seedlings, which have no cultivation value.

Four-year-old trees can change their heads by grafting, select more than three varieties of scions, and harvest them the next year.

Question 8: What's wrong with cherry trees that have been planted for three years without flowering and fruiting? Three-year-old cherry trees do not blossom or bear fruit, which is basically normal. Generally speaking, the ungrafted cherry trees begin to blossom and bear fruit after about four years. Even if there is no result this year, management can't relax. In particular, it is necessary to do a good job in pest control and ensure the normal defoliation in autumn (after the first frost), and hope to bear fruit next year.

Question 9: Cherry trees that don't bloom for two years don't bear fruit. What happened? Cherry trees cannot be pruned casually. The flowering branches are all at the end and will be cut short. Prune until they grow bigger, and branches that are too dense will be cut short. If it is for the sake of good plant shape, we must wait for the fruit to delay, the main branch to top, and the small side branches to bloom.

Question 10: Why don't cherry trees bloom? That depends on what cherry tree it is. If it is China cherry, the tree is short, and it can generally bear fruit by itself. Most unfruitful cherries are big cherries, that is, sweet cherries, which are imported from abroad. The fruit is large, about the size of Kyoho grape, and the self-flowering rate is very low. Many of them are not self-flowering at all, and need to be matched with pollinated varieties to pay attention to normal results. Moreover, it is generally late to enter the fruiting period, which takes about 3-4 years.
