When the bougainvillea is potted, enough base fertilizer should be added to the soil, usually using bone meal, chicken manure or eggshells. When topdressing, do not apply fertilizer to the roots of the plants. You can dilute the fertilizer and apply it along the edge of the pot. Fertilizer is applied once every 7-10 days during the growing season, and fertilizer control is required in autumn and winter. During the growth period, apply nitrogen fertilizer, and before the flowering period, apply mainly phosphorus and potassium fertilizers. Do not apply fertilizer when there is strong sunlight.

1. Fertilization method

1. Base fertilizer: Whether it is potted bougainvillea cultivation or ground cultivation, enough base fertilizer should be added to the soil during planting. Under normal circumstances, bone meal, chicken manure or egg shells can be used. Do not use chemical fertilizers, which can easily burn the roots.

2. Top dressing: When applying fertilizer, do not apply fertilizer to the root system. You can dilute it with water and apply it along the edge of the flower pot. If you get it too close to its roots, it will burn its root system.

2. Fertilization time

Its growth period requires regular top dressing, usually once every 7-10 days. In spring and early summer, fertilization should be done well. In autumn, fertilization usually needs to be controlled slightly, and fertilization can be done about once every half month. It will grow very slowly in winter. Appropriate application of compound fertilizer can help it survive the winter. Fertilization should be done when the pot soil is dry. Fertilization cannot be done when the temperature is too high, especially when the sun is strong at noon. This should be avoided as much as possible.

3. What is the best fertilizer to apply

Nitrogen fertilizer is mainly applied during the growth period, and phosphorus and potassium fertilizer is mainly applied before the flowering period, which will help it bloom more. It is better to use natural fertilizers for normal maintenance, such as decomposed peel fertilizer, beer water, rice water, or organic fertilizer. If you want to apply chemical fertilizers, you should pay attention to the fertilizer application method and do not apply it close to the plant roots.
