Cultivation methods of crape myrtle

Crape myrtle colorful beautiful, long flowering, long life, has been widely cultivated as garden ornamental trees, planted in front of buildings, courtyards, poolside, riverside, lawn and park trails on both sides are very suitable, sometimes also for bonsai, is an excellent flowering tree, has a very good ornamental value, let's take a look at the cultivation method of crape myrtle flower.

Lagerstroemia flower cultivation method

(i) Planting

1. Ground planting: planting from November after defoliation to March of the following year. When planting, leave the trunk 100~120 cm high and cut off the upper part. After waiting for new spring shoot to grow, select 3~4 main branches with appropriate angle and let them bloom.

2, potted plants: potted plants with live seedlings of the old branches are a good way to quickly cultivate bonsai. Due to the soft branches of crape myrtle, potted crape myrtle can be properly climbed. Generally, when the growth of spring shoots stops and the branches tend to be semi-lignified, they are coiled and shaped, and they are pulled by thin palm ropes to make bonsai in various postures.

(ii) Cultivation management

Cultivate crape myrtle should choose deep soil, fertile soil, good drainage leeward. Big seedlings transplant to take the ball, and appropriate pruning branches, otherwise the survival rate is low. Composted organic fertilizer is applied as base fertilizer in planting holes, and water is poured thoroughly after cutting, and then water is poured once after 3 days. Crape myrtle sprouts late, normally in mid-April to the end of April before the leaves, new plants due to root injury, germination will be delayed. So don't mistake it for something that doesn't work and give up management.

After survival of the plant management is more extensive, Lagerstroemia strong, easy to cultivate, the soil requirements are not strict, but planted in deep fertile sandy loam growth best. Sexual love light, should be planted in the lee or the south wall of the courtyard, insufficient light not only flowers less or no flowering plants, and even weak growth, small branches and leaves. Crape myrtle is cold-resistant, but seedlings should do a good job of cold insulation, more than three years old adult plants do not need insulation. Lagerstroemia crape is drought-tolerant and afraid of waterlogging. It can be watered once a year before germination in spring and after defoliation in autumn. If it is not too dry at ordinary times, it is not necessary to water it. Generally, it is watered 1 ~3 times in spring drought. In rainy season, drainage work should be done to prevent water from rotting roots. Autumn is not suitable for watering. Can be applied every year after winter defoliation and before spring germination, such as the application of human feces or sesame paste residue is better, can make the plant grow vigorously in the coming year, flowers big color Yan.

In order to make Lagerstroemia flower flourish, it should be pruned in dormancy period. Because crape myrtle inflorescences are born at the top of new branches in that year, it is necessary to cut back the annual branches again during pruning to concentrate nutrients and make the branches strong. It is necessary to cut off the excessive long branches, dry branches, drooping branches, diseased branches, slender branches and endogenous branches. In the young tree period, the lateral branches at the lower part of the trunk should be cut off in time to make the upper part of the trunk get sufficient nutrients and form a good crown.

Crape myrtle cultivation management extensive, but to cut off dead branches, pests and diseases in a timely manner, and burned. In order to prolong the flowering period, the branches that have bloomed should be cut off in time to make them sprout again and grow the next round of flowering flowers. In order to thicken the trunk, a large number of flowering branches can be cut off, and the trunk can be cultured in concentrated nutrition. Practice has proved that proper management, Lagerstroemia praeparata can make it bloom many times a year, up to 100/120 days.

(iii) Trimming

Lagerstroemia flowers are growing in the spring of germination at the top of the shoot, germination force, crown is not neat, so the need for pruning.

1. Winter pruning: In order to ensure normal flowering and form large inflorescences, winter pruning is very important. The ground planting should cut off the branches of the year at the height of the main branch (fist), so that the strong branches will bloom in the following year; the potted plants should first cut off all the sprouting branches, dead branches and overlapping branches. In order to beautify the modeling, the top of the full terminal buds of other branches should be truncated at 1 cm, and generally only about 5 cm should be reserved.

2. Post-flowering pruning: After flowering in summer, some residual flowers should be cut off to prevent them from bearing seeds, so as to reduce nutrient loss and promote germination and flowering of new branches. Growth pruning should not be on the spring germination of new branches for pruning or short, otherwise easy to cause only long branches do not bloom.
