1. Maintenance method
Raising bougainvillea needs to provide it with sufficient light conditions. It is best to keep the daily light time at 8-10 hours, so that bougainvillea will grow better. In addition, temperature is also very important for the growth of bougainvillea. The winter in the north is cold. , To raise bougainvillea indoors, the temperature should not be lower than 8 ℃. Bougainvillea likes a humid environment, water 2-3 times a week during the growing season, and water every day during the high temperature period in summer to ensure growth, and pay attention to shade in summer. Appropriate fertilization during the growth period, the fertilizer can be used nitrogen, phosphorus and potassium compound fertilizer, so that the nutrition is more comprehensive, pay attention to the application of phosphorus and potassium fertilizer during the flowering period.
2. Matters needing attention
Every year in the spring and autumn, the bougainvillea should be repotted, because the bougainvillea in flowerpots has very limited growth space, and the root system of the bougainvillea must be replaced in the flowerpot, otherwise it will affect the growth. When changing pots, remove some old soil, remove some old roots, and prune the roots properly, which can promote the renewal of the roots. The replacement flower pot should be one size larger, and then prepare some loose and breathable flower soil. Be careful not to damage the root system when potting, and slow the seedlings after potting.
The above is the introduction of bougainvillea flowers several times a year and the cultivation methods and precautions of bougainvillea in flower pots. The flowering period of bougainvillea is relatively long. As long as the maintenance methods are in place, its flowers can bloom for a long time.
