Therefore, bougainvillea is not suitable for planting in the yard in the north, and it can be moved to a warm room before winter, or heat preservation facilities can be built outdoors, and a double-layer heat preservation plastic shed can be built for heat preservation, which can also ensure sufficient light.

Can bougainvillea spend the winter outside?

Bougainvillea belongs to the southern plant, and can overwinter outdoors in the southern region. It is more common in the southern region and can often be seen in some parks or green belts. Moreover, the branches and leaves can remain evergreen and overwinter in the open air, and some even bloom as usual in winter.

How to raise bougainvillea in winter

1, pruning increases resistance

In autumn, bougainvillea can be pruned in time after flowering. Cut short some branches that grow too high and too long, and cut off thinner branches. Then add some multi-element compound fertilizer to make plants grow healthily and increase their resistance.

2. Stop fertilizing

Bougainvillea basically stopped growing in winter. Even if the leaves remain evergreen, they will not sprout new buds and grow new branches. So the demand for nutrients is very small, and there is no need for fertilization.

For those potted bougainvillea whose leaves have completely fallen off, the plants go into dormancy. At this time, it is more difficult to fertilize it, otherwise it will be difficult for plants to absorb it. On the contrary, it is easy to cause fertilizer damage, burn the root system, and finally the root rot phenomenon appears.

3. Keep it bright.

Bougainvillea is a sunny flower, which needs to keep enough light all year round. When bougainvillea is maintained in winter, even if all leaves fall off, it can absorb light through branches and carry out photosynthesis, thus improving the cold resistance of plants.
