Cherry Tree Cutting Techniques and How to Handle Leaf Drop
Cherry trees are still relatively uncommon in China, and only some regions have them, so what about cherry tree cutting techniques? What should you do if the leaves drop?
Cherry tree cutting techniques:
1. Selecting cherry tree cuttings
For cherry trees, choose a young and vigorous mother tree, cut one-year-old sturdy branches from the outer middle-upper part of its crown, keep the top shoot, cut them into cuttings 30-40 cm long, and cut the lower end into a slanted opening. Cuttings taken on the same day must be inserted the same day to prevent the cuttings from losing water, having their cuts damaged, or the tissue necrotizing. Be sure to note that thin and weak cuttings will lower the survival rate, and short cuttings will delay the seedling stage.
2. Making the cherry tree cutting bed
For the cherry tree cutting bed, choose a site that is sheltered from the wind, faces the sun, and has good drainage, and make it into a bed 1 m wide and 30 cm high. Lay a 15 cm thick layer of somewhat fertile sandy loam at the bottom of the bed, then cover the upper layer with 10 cm of yellow-core sandy loam (prepared with 8 parts yellow-core loam and 2 parts yellow sand), and carry out sterilization treatment.
3. Cherry tree cutting time
The best time for cherry tree cuttings is from early to mid-June to early to mid-September, mainly because cherry is a deciduous tree species. Cutting one-year-old large branches should be done before the tree buds sprout, and the cuttings begin to root when the soil temperature reaches above 16°C.
4. Cherry tree cutting techniques
When taking cherry tree cuttings, use a small stick slightly thicker than the cutting, insert it vertically into the cutting medium to a depth of 5-6 cm with a spacing of about 10 cm, then insert the cutting, and press it firm with your hand. After inserting, water thoroughly with a fine-nozzle watering can so that the cutting and soil are tightly combined.
What to do if cherry tree leaves drop:
1. Seasonal changes
[Cause] Generally speaking, cherry trees begin to shed leaves in autumn, and the specific time depends on the local temperature and so on. In some places it is after September, and in others it is November, but overall this is brought about by the change of seasons.
[Solution] It is a normal phenomenon for cherry trees to drop leaves due to seasonal changes, so there is no need to worry; just do the daily care work well.
2. Impact of pests
[Cause] A relatively common cause of cherry leaf drop is pest infestation. The larvae of longhorn beetles can cause the entire branch to shed leaves early under the bark at the base of the trunk, and if the larvae are in the main root, they cause the whole tree to shed leaves early.
[Solution] At this time, attention should be paid to care. If cherry leaves are found to drop early, check whether it is due to pest infestation, and if so, spray pesticides for treatment.
3. Improper watering
[Cause] Improper watering is also one of the reasons for cherry leaf drop. Generally speaking, dry climate, uneven water supply, lack of water, or excessive rainwater accumulation cause poor growth of the cherry tree, blocked nutrient transport, and also early leaf drop.
[Solution] Usually pay attention to watering. Do not water too much, so as not to damage the cherry root system, and do not water too little either, especially during the growing period, when sufficient water must be provided for the cherry to grow.
4. Fertilizer too concentrated
[Cause] Cherry trees do not like heavy fertilizer, so be careful not to apply fertilizer too concentrated. Generally speaking, a nitrogen fertilizer content of 3‰ is relatively suitable. If it is not stirred evenly, the concentration at the bottom becomes higher, which also causes the tree to shed leaves early.
[Solution] Fertilizing cherry trees twice a year is enough, and acidic fertilizer is preferable. One is winter fertilizer, applied in winter or early spring as organic fertilizer such as bean cake, chicken manure, and decomposed fertilizer. The other is after the flowers fall, applying quick-acting fertilizers such as ammonium sulfate, ferrous sulfate, and superphosphate.
Note: Besides the several common causes of cherry leaf drop mentioned above, soil compaction can also cause the cherry root system to exchange with air and thus cause leaves to drop. In fact, there are many reasons for cherry leaf drop, so when you notice it, be sure to check which aspect is the cause and then treat the root cause accordingly, so that you can better care for the cherry.
All right, friends, now you all know how to plant cherry trees, right?
Cherry Tree Management Tips and Pest Control Techniques
As part of the rose family, cherry blossoms bloom in spring, so they are also a symbol of spring. Every spring, cherry trees begin to produce white, light red, and deep red cherry blossoms, and the petals come in single and double forms; the difference is that only single petals can bear fruit. Cherry blossoms are very beautiful. As an ornamental plant, how cherry trees should be managed and protected from pests is very important.

Cherry Tree Management Tips
I. Cherry tree disease prevention and leaf protection
Powdery mildew, brown spot, and sooty mold are the most common diseases of cherry trees. If prevention and control techniques are lacking, they can cause premature leaf drop, so that nutrients cannot accumulate and the quality of the next year's flowering period is affected.The control methods: You can choose 70% thiophanate-methyl 1000x solution and 65% zineb wettable powder 500x solution, spraying once every 15 days. Highly efficient pesticides such as dichlorvos must not be used. Watering should be appropriate, and leaf-surface fertilizer spraying also needs to be increased to ensure the leaves are intact, thick, and dark green.

II. Applying base fertilizer to cherry trees in autumn
Cherry trees usually begin to be given base fertilizer around September 10, after which the fertilizer has enough time to decompose, which lets the cherry tree begin to absorb nutrients during dormancy. The fertilizer types are mainly decomposed farmyard manure, combined with a small amount of chemical fertilizer. For young trees, apply 50 to 75 kg of farmyard manure per plant. Autumn base fertilizer should not be applied too deep; 40 to 50 cm is suitable.

III. Deep digging of the cherry tree root zone
In autumn, cherry trees need to be fertilized. Combined with the application of base fertilizer, turn the soil around the roots once, which can increase root depth, store water and preserve moisture, and raise soil temperature. Clean up dead branches, fallen leaves, weeds, and so on in the root zone, and burn them in a centralized way to eliminate overwintering pest sources and fungal sources.

IV. Autumn pruning of cherry trees
Cherry trees also need pruning. According to the growth condition of the tree, promptly thin out dense branches, crossing branches, and overlapping branches. Diseased and pest-infested branches are also controlled, the ventilation and light penetration of the crown are improved, and tree vigor is increased. Use a sharp knife to smooth and scrape clean the wounds, apply 5-degree lime sulfur solution for disinfection, and then apply protective agents such as tung oil to prevent the wounds from rotting.

Cherry tree pest control techniques:
Cherry trees should be watched for pests at all times. The main pests harming cherry trees are aphids, red spiders, and scale insects. For these pests and diseases, prevention should be the main approach, spraying 3 to 4 times a year: the first time before flowering, the second time after flowering, and the third time in July to August. Try to avoid using dichlorvos to prevent leaf drop. Water appropriately, and increase leaf-surface fertilizer spraying (0.3% to 0.5% urea, 0.3% potassium dihydrogen phosphate) to ensure the leaves are intact, thick, and dark green.

What to Do If Cherry Leaves Turn Yellow and How to Grow Cherry Trees
Cherry blossoms are surely a flower everyone likes very much. Japan's cherry blossoms are the most famous. Right now it is exactly the time when cherry blossoms are in full bloom, and many people have gone to Wuhan to see the cherry blossoms. Cherry blossoms symbolize purity, and the falling flowers are graceful. Cherry blossoms are a kind of flowering ornamental plant, but during the growth process, cherry trees can develop yellow leaves. When we encounter this, we do not know what to do and begin to wonder whether the growing method is wrong. Below, we will explain what to do if cherry leaves turn yellow and how to grow cherry trees, hoping it can help everyone.
What to do if cherry leaves turn yellow
Metabolism
When leaves turn yellow, first look at what kind of leaves are turning yellow, whether they are new leaves or old leaves. If old leaves turn yellow, it is generally normal metabolism, so there is no need to worry; just do the care work well.
Insufficient fertilizer
The most common cause of cherry leaves turning yellow is insufficient fertilizer. The main reason for this situation is that no timely topdressing was done during the cherry's topdressing period, resulting in malnutrition of the cherry.
Solution: Apply acidic fertilizer to the cherry, in an appropriate amount, not too concentrated.
Insufficient light
Cherry trees like warm and sufficient sunlight. If there is insufficient sunlight, it can also cause cherry leaves to turn yellow.
Solution: Choose a sunny place to grow the cherry, but note that the sunlight must not be too intense either, otherwise it is easy to scorch the leaves.
Unclean irrigation
Cherry is a relatively sensitive plant. If the irrigation water source is polluted and unclean, it can easily cause cherry leaves to turn yellow and wither.
Solution: Choose a clean irrigation water source
Overwatering
Cherry trees are relatively drought-tolerant and do not need too much water, so there is no need to water frequently, otherwise it will cause the cherry root system to breathe poorly and make the leaves turn yellow.
Solution: If too much water is accidentally applied, move the cherry to a place with sufficient light and good ventilation to speed up water evaporation. At the same time, appropriate loosening of the soil can be done.
How to grow cherry trees
Applying fertilizer: Cherry trees are fertilized twice a year, and acidic fertilizer is preferable. One is winter fertilizer, applied in winter or early spring as organic fertilizer such as bean cake, chicken manure, and decomposed fertilizer; the other is after the flowers fall, applying quick-acting fertilizers such as ammonium sulfate, ferrous sulfate, and superphosphate.
Watering key points: After cherry trees are planted, the seedlings are prone to drought damage. In addition to sufficient watering at planting, water once every 8-10 days afterward, keeping the soil moist but without standing water. After watering, loosen the soil in time, and it is best to cover the ground surface thinly with grass to reduce water evaporation. Within 2-3 years after planting, to prevent the trunk from drying out, it can be wrapped with straw. But after 2 to 3 years, when the sapling grows new roots and its adaptability to the environment gradually increases, there is no need to wrap it with grass anymore.
Pruning key points: Cherry pruning mainly involves cutting off withered branches, leggy branches, overlapping branches, and diseased and pest-infested branches. In addition, when many branches grow on the trunk of a large cherry tree, several vigorous branches should be retained, and all the rest should be cut off from the base to facilitate ventilation and light penetration. After pruning, disinfect the wounds with medicine in time to prevent pathogens from invading after rain and causing rot. After long exposure to the sun, cherry bark is prone to aging and damage, causing rot, so it should be removed in time and disinfected. After that, wrap the rotted area with leaf mold and charcoal powder to promote the restoration of normal physiological functions.
Repotting the soil: Stop watering the cherry 3 to 4 days before repotting, so that the potting soil is slightly dry. When repotting, hold the flowerpot upside down with the left hand, then pat the flowerpot with the right palm, or push and press the drainage hole of the flowerpot with a wooden stick, and the cherry can come out of the pot together with the soil. For the cherry root system that comes out of the pot, dense white roots are distributed along the edge of the potting soil. Use a bamboo stick to loosen the fine roots, and remove most of the old soil, retaining one third, and transplant it with soil into a new pot.
The above is what we have explained about what to do if cherry leaves turn yellow and how to grow cherry trees. Is everyone clear now? For more home decoration knowledge, please pay attention.
