How and when to plant Lagerstroemia speciosa How to plant Lagerstroemia speciosa?

Lagerstroemia indica has a long flowering period from June to September, with flowers and fruits coexisting and orderly fruits. From September to165438+1October, when the capsule turns from green to brown and some individuals start to crack slightly, the fruit sequence is picked, and the mature fruit at the base of the fruit sequence is collected, and the peel is removed. The seeds are stored in containers after drying, and the storage place should be ventilated and dry.

2. Soil preparation before bed

Lagerstroemia indica has strong adaptability to the environment, is drought-resistant and cold-resistant, and has no strict requirements on soil, but it grows best when planted in deep, fertile, loose, slightly acidic and acidic sandy soil. First, the seedbed soil is hoed loose, and the sowing ditch is treated according to the specifications of 20~25cm wide and 2~3cm deep.

3. Seed germination accelerating treatment

In order to make seeds germinate orderly and quickly, seeds should be germinated before sowing. First, the seeds should be disinfected. The common method is to soak in 0.2% potassium permanganate for 1-2 days, and then rinse with clear water for several times to remove the residual potassium permanganate. After cleaning, soak the seeds in warm water at about 45-50℃ for 2-3 days, then take out the seeds and dry them slightly.

water

Ziwei likes wet but is afraid of waterlogging, so water it properly. Too much watering will cause water accumulation, which will lead to the decay and death of Lagerstroemia indica. However, if water is not replenished in time, it will stop growing or die because of lack of water, especially during flowering. When the temperature is high in summer, the water of potted plants evaporates quickly, so it is advisable to water them in the evening. If it is shallow, it can be watered once in the morning and once in the evening to meet the needs of daytime growth. Water every other day in spring and autumn. In winter, Lagerstroemia indica should keep the basin soil moist, water it every few days, and water it at noon when the temperature is high. Wei Zi bonsai is fond of light and usually grows in sunny and well-ventilated environment.

5, fertilization

Lagerstroemia indica should be applied with a slightly thicker layer of organic fertilizer as base fertilizer after autumn, but in general, heavy fertilizer should not be applied to Lagerstroemia indica piles to prevent the branches from growing white. Lagerstroemia indica should pay attention to the coordinated application of nitrogen and phosphorus fertilizers. Apply decomposed fertilizer every half a month during the growing period. Nitrogen fertilizer should be applied once after each pruning, and 0.3% urea solution can be added to the fertilizer solution to promote the growth of sprouting new buds and new branches, and then phosphorus-based fertilizer should be applied to provide nutrients needed for flowering in time. Fertilization should be carried out at night and watered once the next morning. Fertilization is not suitable in rainy days and when the basin soil is wet.

Step 6 turn the washbasin over

Turn the pot and change the soil once every 2 ~ 3 years. In order to blossom every year or four times a year, it is required to turn over the pots and change the soil once a year, preferably before germination in spring. After the pile head comes out of the basin, remove the surrounding soil and some rotten roots, thick roots, long roots and over-dense roots, plant the plants in the basin, add culture soil to tamp them, and pour enough water. The cultivated soil must be rich in organic matter, well drained and breathable, and have sufficient fertility to ensure that it is full of flowers.
