The crape myrtle is graceful and graceful, and the summer and fall and autumn seasons are chlorophyll red and beautiful. The flowering period can be over 100 days. To make potted crape myrtle more, flower Yan, multiple flowering, in addition to the selection of dwarfed varieties, we must strengthen the plastic pruning, fertilizer and water management and other measures to control the flowering period. Choose an annual pot of seedlings, or use seeds to seed it in spring. Potted crape myrtle requires plant type dwarfing, and pruning is the key to promoting multiple flowering and multiple flowering. After the seedlings are planted on the pots, the heads are set at 15 to 20 centimeters from the ground and the seedlings are sowed at a height of about 15 centimeters. After the main buds sprouted on the new shoots, three strong branches in different directions were selected as the main branches, and the rest of the shoots or all were trimmed off. The main branch grows to 8 to 10 centimeters topping, inhibits prolonged growth, promotes division of lateral branches, and has a compact, low, naturally happy-to-shape canopy. Lagerstroemia sprouts strong, extremely resistant to pruning, generally divided into the growing period of buds and winter dormant pruning. The main purpose of pruning is to adjust the tree structure, promote more branches, more flowering, multiple flowering, old tree renewal, prolong the flowering period, reach the main trunk is short, branches are low and even and compact, grow neatly, the crown is happy, airy and transparent. Lagerstroemia flower buds are formed at a fast rate. Therefore, rotating pruning can promote multiple shoots and shoots many times. Autumn and winter flowers after a strong pruning, sparsely cut through the dense branches, overlapping branches, leggy branches, dead branches, pests and branches. Heavy shearing of main lateral branches, extension of branches, compression of old branches, so that the spring buds more branches, early flowering. When spring shoots grow 10 to 15 centimeters in length, 8 to 10 centimeters long toss is retained, nutrients are concentrated, branching is promoted, and flowering branches are increased. From the end of May to mid-June, after the first flower cut, the upper part of the flowering branches was cut, leaving strong buds to germinate the lower axillary buds and regenerating the buds of the new shoots. The second flowering occurs from late July to early August. After flowers and flowers are cut off, the residual flowers are cut off in a timely manner to accumulate nutrients and promote flower bud differentiation of new shoots. The third flowering occurs from late August to early September. In this way, repeated rounds of pruning, corresponding to increase fertilization material. During the growing season, thin spatula fertilizer is applied once or twice a month, and the amount of fertilizer is increased after flowering. The liquid fertilizer is applied every 7 to 10 days during the flowering period from July to September, and 0.2% potassium dihydrogen phosphate is sprayed every 10 to 15 days. Every time after the flowers are thanked to cut off the residual flowers, to prevent the results and reduce food consumption.
