In order to improve the resistance of roses and reduce pests and diseases, be sure to supplement roses with nutrient solution, which is rich in nitrogen, phosphorus and potassium and has been enriched with various organic matter, minerals and amino acids to promote the growth and flowering of roses and improve their resistance.

Soil preparation and repotting

If Bougainvillea is to grow well, you must not be careless when it comes to soil. Choosing suitable soil according to its habits and repotting at the right time can absolutely make Bougainvillea bloom more smoothly. Generally speaking, Bougainvillea likes loose, fertile, slightly acidic soil that is also breathable. If growing it as a potted plant, you can consider mixing leaf mold, peat soil, garden soil and coarse sand in a ratio of 1:1:1:1. After mixing the soil, it is best to add a little decomposed cake residue at the bottom of the flower pot as base fertilizer. Bougainvillea grows relatively fast, so it is generally best to repot once every spring to let the roots spread out more, which is beneficial to plant growth.

Watering has its rules

Bougainvillea is a southern flower. Although it can also survive in the north, there are naturally some differences in care. Especially when it comes to watering, you must distinguish between different seasons. Generally speaking, winters in the north are relatively cold, so when watering you should control the amount as much as possible and only need to keep the potting soil moist. In summer, because temperatures everywhere are generally higher than the normal temperature for Bougainvillea growth, you can increase the water supply. In southern regions you can water once in the morning and once in the evening, while in the north, although it does not need to be that frequent, three times every two days is still necessary. As for spring and autumn, watering once a day is enough.

Fertilizing is key

People often use Bougainvillea to decorate flower walls, which actually relies on its characteristic of blooming abundantly. But if you want abundant blooming, you actually need to continuously supplement various trace elements. Fertilizing is a problem we need to pay attention to, especially before the summer flowering season arrives, when Bougainvillea may need a larger intake of nutrients. So before the flowering season, you can use a flower-promoting organic nutrient solution once every 10 days to promptly supplement nutrients for Bougainvillea, letting Bougainvillea bloom all over the tree, and in this way it is also less likely to drop buds. If you want the flowering to last long, you can also continue fertilizing during the flowering season, so that you can enjoy the flowers longer.

Do not neglect light and temperature

The suitable growth temperature for Bougainvillea is 15-30 degrees Celsius, among which May to September is 19-30 degrees Celsius, and October to April of the following year is 13-16 degrees Celsius. In summer it can withstand high temperatures of 35 degrees Celsius, and in winter the ambient temperature should be maintained at no lower than 5 degrees Celsius, otherwise it is prone to frost damage and leaf drop. Therefore, we need to adopt different temperature control strategies in different seasons. As for sunlight, well, all I can say is that Bougainvillea loves it the most. Apart from appropriate shading in the summer afternoon, at other times you can give it a beautiful sunbath, ensuring the flowers bloom especially vividly.
