Watering: Follow the principle of watering if it is not dry and watering thoroughly. Keep the pot soil dry from late autumn to early spring. Cuttings: Choose strong annual branches with a depth of 8-10 cm. Flowering period: The remaining flowers after the flowering period should be cut off, and the leggy branches, diseased branches, and stacked branches should be cut off. Fertilizer: Apply base fertilizer, top-dress fertilizer before new branches sprout, apply less in autumn and no fertilizer in winter.

1. Watering

Crape myrtles potted at home also need to receive sunlight similar to that outdoors. Even in high-temperature environments, they generally do not need shading.

The cultivation location should be as far away from the wall as possible on brick and dirt floors to prevent poor ventilation on the wall from raising the temperature of the small environment, which is detrimental to the growth of crape myrtle.

Watering in all seasons should follow the principle of "don't water dry, water thoroughly". The specific amount of watering should be based on the actual moisture content of the pot soil. If there is water leakage in the pot soil , the soil should be replenished in time to increase the density of the pot soil.

Fertilizer and water should be applied during the spring budding period, summer budding period and flowering period. From late autumn to early spring of next year, the amount of water should be controlled and the pot soil should be kept as dry as possible.

2. Cuttings

are specifically divided into two types: twig cuttings and hard twig cuttings. Generally, young branches are cut during the rainy season, and hard branches are cut in spring. The survival rates are both good.

Cuttings should be taken from annual thick and strong branches on the vigorously growing mother plant, and pruned to branches about 10-15 cm long. The depth of the cuttings is preferably about 8-10 cm.

It usually takes about 20 days to take root. Proper shading and moderate watering are required. The branches have a high survival rate and can grow to about 60-80 cm that year.

3. Flowering period

Lagerstroemia itself has a strong branching ability and a large number of long shoots, so it is necessary to cut off the remaining flowers after the flowering period to promote new growth of the plant and make the next round of flowering branches grow as soon as possible, thereby extending the flowering period.

At the same time, leggy branches, diseased branches, stacked branches and intersecting branches should be cut off in time to prevent excessive consumption of nutrients.

4. Fertilization

Basal fertilizer should be applied to potted crape myrtle. Top-dressing fertilizer can be applied before new branches germinate or between May and June. Apply less in autumn and not in winter.

In addition, it is not suitable to fertilize in hot weather and rainy weather in summer. Fertilization at other times should follow the principle of "fertilize thinly and apply frequently".

Excessive fertilizer can easily cause leggy branches and leaves, while too little fertilizer can easily cause weak branches and yellow leaves. In severe cases, the growth of the whole plant will be weakened and there will be few or no flowers.

5. Replace the soil

For potted crape myrtles, it is best to replace the 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). The base fertilizer can be organic fertilizer (bone meal, bean cake meal, etc.).

Be careful to avoid direct contact between the roots and the fertilizer, otherwise it will burn the roots and harm the normal growth of the plants.
