When is the best time to plant crape myrtle? When is the best time to plant crape myrtle trees?

Crape myrtle tree. The planting time is usually in March or April every year.

Crape myrtle tree planting.

1. Land selection and land preparation.

Crape myrtle likes to grow in sunny and arid places, has strong cold and drought tolerance, and has strong growth adaptability. It can grow normally in most soils, but if we want to grow on a large scale, we still need to choose slightly acidic soils with sufficient fertility, thick and soft, and drainage and irrigation. Suitable soil can prolong the flowering period of crape myrtle and improve the ornamental value of crape myrtle.

After selecting the land, it is necessary to do a good job of land preparation, and turn it deep and raked about 26 cm to improve the permeability of the soil. Then apply enough farm fertilizer and an appropriate amount of superphosphate, control the amount of fertilizer according to the planting area, and finally level the furrow to prepare for planting.

2. Sow seeds at the right time.

The flowering period of crape myrtle is about 3 months, and the time is long, and the flowers and fruits grow together. Around October, the seeds are removed from the fruit, dried and stored in containers. Before sowing, germination and disinfection should be done, and the seeds should be put in potassium permanganate.

After soaking in the solution for about 2 days, clean it. Then soak it in warm water at about 48 degrees Celsius for about 3 days, and then dry it after soaking. Then, according to the planting area, weather, etc., the seeds are sown, covered with fine soil after sowing, and watered enough, and the seedlings can appear after about two weeks.

3. Water and fertilizer management.

In winter and spring, it is necessary to keep the soil moist, and water twice a day after the temperature rises in summer, and when there is a shortage of water, the watering frequency can be appropriately increased every day to prevent crape myrtle from dying due to lack of water. Crape myrtle has a large nutrient requirement in the growth, but the fertilizer tolerance is not high, and excessive fertilization can easily lead to the growth of crape myrtle trees, reduce permeability, and affect the growth of crape myrtle.

However, the amount of fertilizer should not be too small, otherwise it is easy to lead to insufficient nutrition of crape myrtle, weak branches, yellow leaf color, reduce growth, decrease the flowering rate, or even fail to flower, and seriously reduce the ornamental value. Therefore, we should apply water-soluble fertilizer to fertile leaves reasonably, apply more in spring and summer and other peak growing seasons, and control fertilizer application in the remaining two seasons.

4. Field management.

Crape myrtle has a relatively strong growth ability, so it is relatively simple to manage, but we should pay attention to pruning old dead branches, pest and disease branches and other weak branches that are not conducive to growth, and burn them intensively. In order to prolong the flowering period of crape myrtle, it is necessary to cut off the branches that have already bloomed to promote the growth of re-budding and branching. If you want to focus on cultivating the trunk, you should cut off most of the branches and concentrate the nutrients on the trunk.

In addition, the growth of crape myrtle has a greater demand for light, and doing a good job of pruning can also improve the ability of light transmission. We also need to pay attention to providing sufficient light for crape myrtle to promote the growth of crape myrtle.

The best time to plant crape myrtle trees is in March, spring.

Crape myrtle tree cultivation needs to use alkaline soil, can add some potassium trim acid to the soil to adjust the pH value of the soil, generally sowing in March to April every year, potting needs to water the soil thoroughly, and then sowing, crape myrtle daily growth does not need too much water, you can increase the amount of watering during the growth period, crape myrtle flowers like sunlight, need to be placed in a sunny place, 3-9 months can be fertilized, winter into the dormant period can stop fertilization.

The transplanting time of crape myrtle flowers is from March to early April, with the Qingming Festival being the best, followed by autumn. When transplanting, the plant should be transplanted with soil, leaving the main trunk 100 to 120 cm, cutting the upper part, and waiting for the new shoots to grow, leaving 3 to 4 main branches at the most suitable angle for it to flower.

1.Transplanting is carried out after autumn defoliation and before bud germination in spring. Small seedlings can be transplanted with bare roots, and large seedlings need to be transplanted with soil balls.

When planting, apply compost, irrigate twice in a row, and irrigate, loosen the soil, and weed in a timely manner. Crape myrtle planting is carried out in the spring, and bare roots can be planted. When planting seedlings, keep the root system intact.

2.Planting locationThe planting site should be sunny, moist and fertile, and well-drained loam.

3.Water and fertilizer management: Apply sufficient basal fertilizer before planting, and the fertilizer can be used with well-rotted human manure, circle fertilizer, manure and compost. In the first three years after planting, 10 to 15 kg of fertilizer should be applied in the root cavity before germination in winter or spring every year (mainly organic fertilizers such as compost and cake fertilizer), and a certain amount of compound fertilizer can also be applied as appropriate.

After surviving, crape myrtle should be watered once a year in spring, 3 to 4 times thereafter, and 1 to 2 times during the flowering period. In North China, pour frozen water once before freezing, and pay attention to drainage after rain.

4.Plastic pruning and pruning of crape myrtles planted should be pruned. When planting larger crape myrtles, they should be re-cut before planting, and the trunk of a uniform height can be determined according to the needs of cultivation, and the upper crown can be cut off, so that the new crown grows vigorously and neatly and beautifully.

During the growth period of crape myrtle seedlings, the side buds at the lower part of the stem should be removed at any time, so that the terminal buds and upper branches can get more nutrients and grow strongly, and form a complete crown as soon as possible. In the growing season, the residual flowers and branches should be pruned in time, and new branches should be promoted to prolong the flowering period, and the crape myrtle inflorescence should bloom at the top of the new branches. After the leaves fall, it is necessary to thin and prune long branches, weak branches, diseased branches and wilted branches.

Pest and disease control.

There are mainly aphids, crape myrtle scales, large moths and coal pollution diseases induced by insect pests, which should be prevented and controlled in time.

For aphids, you can spray 800 to 1000 times of bitter tobacco emulsifiable concentrate, or 50 anti-aphid 3000 times, or 2500 to 3000 times of enemy killing, or 6 imidacloprid 3000 to 4000 times of liquid and other one of the foliar spray, pay attention to safety when spraying.

For crape myrtle velvet scale, within 7 days after the peak hatching period of nymphs, when wax has not formed or just begun to form a waxy layer, spray 1500 to 2000 times of 40 speed scale emulsifiable concentrate, 2000 times of 6 imidacloprid soluble solution, and 2500 times of pyrethroid pesticides. The above three agents are used alternately, sprayed every 7 to 10 days, and sprayed 2 to 3 times in a row, which can achieve good results. The key to spraying is to seize the timing (nymph stage), once the scale is formed, it is difficult to spray effectively.

For the large moth, the pouch of the tree moth can be seen after the tree leaves fall in winter, and it is manually removed; Trap and kill adult insects with frequency-vibration insecticidal lamps; Demoiselle moth larvae are more sensitive to trichlorfon agents, and good results can be achieved by using 1000 to 1500 times of 90 trichlorfon crystals. You can also use 3500 to 4000 times of deltamethrin EC, or 1000 to 1500 times of 50 octathion EC, 1000 to 1500 times of 20 chrysanthemum EC, etc., and strive to be uniform and thoughtful.

Coal stain disease is mainly caused by the secretion of stinging and sucking pests such as aphids and scale insects, and it is key to control them.

Crape myrtle trees can be transplanted after the leaves have fallen and before germination.

It is advisable to plant after the leaves have fallen in November to March of the following year.

Seedlings are sown in November and emerge the following year. It is best planted in early spring before germination!

It's better to be in the spring, what kind of specifications do you want?

Crape myrtle trees can also be planted in June.

Nowadays, people's aesthetics are getting higher and higher, and they don't pay attention to the advantages of landscape trees themselves, and the more beautiful they are, the more people like them, regardless of whether they can survive the winter or not. Here I would like to introduce you to a tree that will never be eliminated and which is increasingly favored by landscaping varieties. Crape myrtle is an excellent seedling for garden landscape ornamentation, and is also one of the good stump bonsai species, crape myrtle has strong adaptability to environmental conditions, cold and drought resistance.

The soil requirements are not strict, but the planting is in the fertile, deep, loose and slightly acidic, acidic soil to grow robustly, and the flowering period can reach more than 100 days. Crape myrtle is a precious environmental protection plant in China. Crape myrtle tree cultivation technology, propagation method, crape myrtle can be sexually propagated or vegetatively reproduced.

Seed propagation can be harvested in mid-November, threshed in the sun, dried and stored, sown in early March of the following year, and shaded with shade nets after sowing. Flowers can be seen in autumn when the seedlings are cultivated, but the flower color of crape myrtle propagated by seeds is prone to change. Crape myrtle trees can also be propagated by cuttings, and most of them are propagated by cuttings in order to maintain the variety and propagate seedlings quickly.

Cuttings can be divided into old branch cuttings and young branch cuttings. Old branch cuttings are carried out in February in spring, and the 15 cm long branches are selected as cuttings, and soaked in water before cutting. Environmental requirements for crape myrtle tree cultivation Crape myrtle is a sun-loving plant, so it should be planted in a sunny place.

If you plant it individually, it is recommended to plant crape myrtle on the south side of the yard, and if you are planting it in the wild, it is recommended to plant it in a leeward and sunny place. If planted in a shady place, crape myrtle will not be able to get enough sunlight, which will affect its life and health and the number of flowers.

Crape myrtle tree cultivation requires water crape myrtle is cold and drought tolerant, and it does not need to be cared for too much for adult trees or crape myrtle trees that are more than three years old, but when the saplings are small or just planted, they are not firmly rooted and their self-resistance is not strong.

Crape myrtle is not afraid of drought, but it is afraid of waterlogging, so according to the growth characteristics of crape myrtle, crape myrtle should be planted on higher ground to prevent crape myrtle trees from drowning during floods. If it's not too dry, you don't have to water crape myrtle. Before the flood season, it is necessary to prepare for waterlogging to prevent crape myrtle trees from drowning in heavy water.

Crape myrtle tree cultivation requires fertilizer, and crape myrtle trees, like all other tree species, need to be fertilized and pruned. Studies have shown that the best time to fertilize crape myrtle trees is after the leaves fall in winter and before germination in spring, when crape myrtle trees should be applied with human and animal manure or fertile leaf water-soluble fertilizer, which can provide nutrients for crape myrtle trees to grow better.

Repairing branches and leaves is also essential. In autumn, when crape myrtles have fallen their leaves, all branches are clearly visible, and it is easier to prune them at this time. When pruning, you can cut off long, dead, and diseased branches, and cut out a beautiful crown for crape myrtle according to your own ideas.

It can be planted in June, crape myrtle trees are not very picky about the growth environment, it is a deciduous shrub plant with very strong adaptability, generally speaking, it is best to plant crape myrtle trees in areas with sufficient sun and rich soil, and in the choice of environment, crape myrtle trees can be planted all year round.

Crape myrtle flowers love sunlight and should be kept in good sunlight during the growing period. Water in time, keep the soil moist, and increase the frequency of watering in summer. Crape myrtle flowers are more fertilizing, and it is necessary to apply Bika water-soluble fertilizer reasonably in the spring and summer growth seasons, reduce fertilization in autumn, and stop fertilization during the dormant period in winter.

To ensure good soil factors, it is required to be loose, fertile and well-drained, and the potting soil needs to be replaced every two to three years. Pay attention to pruning at ordinary times, and remove the residual flowers in time after flowering.

Under normal circumstances, it is not easy to plant plants in June, and the survival rate after planting is very low, especially the crape myrtle trees planted outdoors are not easy to survive when planted in this season, because the temperature is high and it is easy to cause dehydration and dry up and die after planting. It is usually better to plant in winter or spring.

Crape myrtle is very tolerant of heat, and the temperature should be adjusted to 15-40 during the cultivation period, which is the most suitable range for its growth.

Precautions for the maintenance of crape myrtle flowers.

1. Watering. Crape myrtles that are potted at home also need to be exposed to similar sunlight as outdoors, and they generally do not need shade even in hot environments.

The cultivation location should be selected as far as possible on the brick floor and mud ground away from the wall, so as to prevent the poor ventilation of the wall and raise the temperature of the small environment, which is not conducive to the growth of crape myrtle.

Watering in all seasons should follow the principle of "not dry and not watering, watering is watered thoroughly", the specific amount of watering should be determined according to the actual wetness of the potting soil, if there is a leakage of potting soil, it is necessary to timely replenish the soil to increase the density of the potting soil.

Fertilization should be applied at the budding stage in spring, budding and flowering in summer, and the amount of water should be controlled from late autumn to early spring of the following year, and the potting soil should be kept dry as much as possible.

2. Cuttings. Specifically, it is divided into two types: young branch cuttings and hard branch cuttings. Generally, young branch cuttings are carried out in the rainy season, and hard branch cuttings are carried out in spring, and the survival rate is good.

Cuttings should be selected on the vigorous mother plant to take the annual thick and robust branches, pruned to about 10-15 cm long branches, the depth of the cuttings is about 8-10 cm as well.

It usually takes about 20 days to take root, and with proper shade and proper watering, the survival rate of the shoots is high, and it can grow to about 60-80 cm in the same year.

3. Flowering period. Crape myrtle itself has a strong ability to grow branches and a large number of long shoots, so it is necessary to cut off the residual flowers after the flowering period, promote the new growth of the plant, and make the next round of flower branches grow as soon as possible, so as to prolong the flowering period.

At the same time, it is also necessary to cut off long branches, diseased branches, stacked branches and interspersed branches in time to prevent excessive nutrient consumption.

4. Fertilization. Basal fertilizer should be applied to crape myrtle pots, top dressing can be carried out before new branch germination or between May and June, less in autumn and no in winter.

In addition, hot weather and rainy weather in summer are also not suitable for fertilization, and fertilization at other times should follow the guidelines of "thin fertilizer and diligent application".

Excessive fertilizer is easy to make the branches and leaves grow, too little fertilizer is easy to make the branches weak, the leaves are yellow, and the growth of the whole plant is weakened in a serious way, and there are few flowers or no flowers.

5. Soil exchange. Potted crape myrtles are best to change the potting soil every 2-3 years.

The cultivation soil can be mixed according to the ratio of loose mountain soil: pastoral soil: fine river sand (5:3:2), and organic fertilizer (Trim microbial agent, bone meal, soybean cake powder, etc.) can be used for base fertilizer.

Pay attention to avoid direct contact between the root system and the fertilizer, otherwise it will burn the roots and hurt the roots, endangering the normal growth of the plant.
