[Daily flower care tips to share] Bougainvillea care, do this, 100% flowering
1. Soil: Use slightly acidic soil with good drainage in terms of soil. It is better to use sandy soils rich in humus, loose, fertile and permeable, and to avoid clay. The pots need to be changed once a year.
2. Water and fertilizer: it can tolerate drought, can not accumulate water, if too much watering, it will lead to the rot of the root system of the plant, affecting the growth rate. Bougainvillea should control the water before flowering, and in the summer, the amount of water can be increased in moderation, and in the winter, the bougainvillea enters the dormant period, and there is no need to water or reduce the amount of watering. Potassium dihydrogen phosphate is used once for 20 days during the period of vigorous growth to maintain adequate nutrients.
3. Light: growing in a well-lit environment, the flowers of the bougainvillea will be brightly colored, in addition to the summer need to be placed in the semi-shaded place for maintenance, other times, you can maintain the sunshine all day, the sunshine can not be less than 8 hours, when necessary, you need to fill the light, keep the light sufficient.
4. Pruning: When pruning, you should master the principle of "short, heavy, thin", after each flower, cut off some of the flowers, dead branches, and long branches that have withered, saving nutrients so that the bougainvillea can better send out side branches.
5. Disease and pest control: the main pests are leaf beetles and aphids, and the common diseases are mainly blight. Usually, it is necessary to strengthen the loose soil and weeding, remove dead branches and diseased leaves in time, and pay attention to ventilation to reduce the spread of the source of disease. Medication if necessary.
Propagation points:
(1) Cuttings propagation: leaf flower propagation to cuttings mainly, summer cuttings into the survival rate is high, cuttings should choose an annual semi-woody branch, cut into 10 ~ 15cm segments, inserted in the sand bed, at a temperature of 20 ~ 25 ° C, 20 ~ 25 days can take root, 40 days after potting, the next year into winter can flower. If the cuttings are treated with hormones before cuttings, they can promote rooting and improve the survival rate.
(2) High-pressure propagation: the pressing strip can be used by the ordinary pressing strip method, mostly in the spring and autumn, the pressing part can be carved first, and then buried in the soil, maintaining a temperature above 20 ° C, and can be rooted in about 20 days.
Colonization of pots: Triangular plum cuttings are planted into pots after they are alive, and the seedlings that are alive for 40 days are refined for a week under strong sunlight and watered with thin fertilizer. Plant pots in 50 to 60 days, put the cuttings in pots, float the substrate from the roots, or directly pour out the roots and separate them and bring part of the matrix into the culture soil.
