Can bougainvillea spend the winter outdoors in northern winter?

Bougainvillea can't spend the winter outdoors in the north, not only in the north, but also in some areas with low temperature in the south. Bougainvillea will be frostbitten at minus five degrees. To take good heat preservation measures, you can build a double-layer heat preservation plastic shed to ensure sufficient light.

Bougainvillea is the new favorite of flowers and is deeply loved by people. Many friends also like to make bougainvillea into beautiful bonsai. It is really a beautiful enjoyment to look at the lush foliage and gorgeous colors. There are also many varieties of bougainvillea, with bright double petals and delicate green leaves, which are very pleasing to the eye.

In the south, especially in Hainan and Guangzhou, bougainvillea is endowed with unique conditions and mild climate. There is no need to worry about freezing injury, and even a little fertilization. It can bloom all year round and even form a sea of flowers, but bougainvillea in the north will become a problem if it overwinters. This guy can't stand the cold after all. Now briefly talk about the wintering problem of bougainvillea in the north!

1. What is the low temperature that bougainvillea can tolerate in the north?

As we all know, bougainvillea can't stand low temperature. What flower friends want to know is, what is the low temperature limit that bougainvillea can endure? Speaking of which, we should talk about sunshine. It can be said that the sunshine in winter is of great significance to improve the cold tolerance of bougainvillea. I tried it myself. If bougainvillea is placed in the sun in winter, even if the temperature is below five degrees, there is still no problem, but if you can't see the light, it will also cause different degrees of freezing damage at six or seven degrees. Therefore, the low temperature that bougainvillea can endure has a lot to do with light.

According to this principle, generally speaking, sufficient sunshine can enhance the photosynthesis of bougainvillea, make it produce more energy and nutrients, and its natural ability to resist low temperature will become stronger. To sum up, sufficient light is a necessary condition for bougainvillea to overwinter.

Second, in order to make bougainvillea safe for the winter, in addition to light, proper fertilization is needed.

If bougainvillea wants to spend the winter safely, it should also pay attention to fertilizing before it overwinters, and so should autumn. If bougainvillea wants to improve its cold-proof ability, it can use some decomposed organic fertilizer in autumn. This kind of organic fertilizer has balanced nutrition, which is beneficial to the absorption of bougainvillea and can improve the soil. Bougainvillea bougainvillea retains these nutrients, and its cold-proof ability is naturally enhanced.

Of course, bougainvillea can also use some compound fertilizers in autumn, in which phosphorus and potassium elements are also of great significance for bougainvillea to overwinter. At this time, it is recommended that you never apply nitrogen fertilizer at this time, otherwise bougainvillea may flourish in autumn, and too delicate leaves will be frostbitten in winter.

Third, bougainvillea can survive the winter safely, and the supercooled areas can be wrapped in large plastic bags.

Bougainvillea is colorful and widely planted in the north and even the northeast, but without heating, Bougainvillea in these areas can't survive the severe winter. What should I do? At this time, you can build a small arch shed for the flowerpot, and put a big plastic bag on the small arch shed to let the bougainvillea spend the winter beautifully. Practice has proved that if bougainvillea bougainvillea wrapped in a large plastic bag is placed in the sun, the internal temperature will even be more than ten degrees higher than that outside, and it can be covered with a broken cotton coat at night, so that bougainvillea bougainvillea basically does not have to worry about freezing injury.

If possible, you can naturally put bougainvillea in the heating room, and the temperature should be above 20 degrees. If bougainvillea blooms frequently, it can continue to blossom, but remind me that bougainvillea in the heating room should also see more sunshine, more water and use more compound fertilizer. After all, the temperature has risen!

Fourth, summary.

Bougainvillea, if the temperature is low in winter, we should also pay attention to water control and keep the plant material slightly dry to avoid freezing injury. If you water it, wait for the surface of the plant material to dry for one or two centimeters, and then pour it thoroughly to avoid half water. If it is not a greenhouse, don't fertilize it, because the root system is dormant at this time.

In order to increase the playability of bougainvillea, I suggest you do some grafting, and by the way, do some of the same bougainvillea, which is leafy and colorful. Do you find it attractive? The aesthetic feeling obtained by proper tossing is different from others and worth it. In my spare time, there is no end to slow operation.
