Is bougainvillea hardy?

Bougainvillea is not cold-tolerant, and the suitable growth temperature is between 20℃ and 30℃. In winter, bougainvillea usually needs to be put indoors for the winter, which requires sufficient illumination, no fertilization, and only a little water is poured every month to keep the soil from drying and cracking; If bougainvillea cannot be maintained indoors, it is generally necessary to build a transparent shed to protect it.

Bougainvillea is not hardy.

Bougainvillea is a cold-tolerant plant, which is suitable for growing in a warmer environment. The suitable growth temperature is between 20-30℃. If the ambient temperature is lower than 5℃, the life activities of bougainvillea will almost completely stop, and freezing injury or even death will occur if it is kept in this environment for a long time.

Bougainvillea is not cold-tolerant, so wintering is an important problem. In winter, bougainvillea generally needs to be placed indoors for the winter, and sufficient light should be paid attention to during indoor maintenance, otherwise it is prone to dead leaves, and long-term rainy weather can be filled with fill light lamps.

Indoor maintenance, the temperature is generally not too high, do not need fertilization, just pour a little water every month to keep the soil from drying and cracking. If the indoor environment is very good, and there is little difference between it and its normal growth environment, you can apply a thin foliar fertilizer once every half month.

If it is impossible to maintain bougainvillea indoors due to conditions, it is generally necessary to build a shed, cover it with transparent plastic film, or place transparent plastic bags on the spot. If you put on a plastic bag, you need to take it off at warm noon to prevent bougainvillea from being suffocated by air.
