Keep bougainvillea at home, and remember to do four things for it after winter to effectively improve the cold resistance.

Now just entering the light snow solar term, the weather is getting colder and colder, and people have put on warm and thick clothes.

Bougainvillea has poor cold tolerance. As the temperature continues to drop, we should be more careful in maintenance. If the maintenance method is not correct, it will easily lead to "wintering death".

Flower friends who have bougainvillea at home should remember to do four things for it after winter, which can effectively improve the cold resistance of plants and avoid freezing injury.

1, simple pruning

Bougainvillea is a plant that is afraid of cold. Except for a few hot areas such as Guangxi, Guangdong and Hainan, which can spend the winter in the open air, most other areas must move back indoors in time after the temperature drops in winter.

Bougainvillea will have large yellow leaves at low temperature, and its branches will be frozen for a long time. If we continue to let it go, the roots will be frostbitten, and finally the whole plant will freeze to death.

If the bougainvillea at home has not yet entered the room, please move it home quickly.

After a year's growth, bougainvillea branches tend to be messy, which not only takes up a lot of space, but also tends to get sick. You need a simple trim before entering the room in winter.

As long as it is simple pruning, if it is cut too hard, plants will germinate and sprout again after the indoor temperature rises, consuming a lot of nutrients.

This is not conducive to bougainvillea in winter, and there may be a problem of "wintering death".

Before pruning bougainvillea, put the scissors on the fire for baking and disinfection.

Clean up residual flowers and dead leaves, cut off weak branches, cross branches, diseased branches and over-dense branches, and then cut off long branches to ensure that the whole plant is well ventilated, clean and tidy.

2. Keep the environment warm

Bougainvillea is a tropical plant, native to Brazil. It likes warm environment and has poor cold tolerance. Even if it is put indoors in winter, there is a problem of paying attention to the indoor environment.

It is best to keep the indoor temperature above 15 degrees. As long as it is above 15 degrees, bougainvillea can continue to grow normally.

If it is impossible, at least keep the temperature above 10 degrees.

When you open the window in winter, you can't let the cold wind blow the bougainvillea directly to avoid frostbite of the branches.

3. Apply some antifreeze fertilizer

Families that raise bougainvillea always have high phosphorus and potassium fertilizers such as potassium dihydrogen phosphate and Huaduoduo No.2. ..

Flower friends generally use high phosphorus and potassium fertilizer as flower-promoting fertilizer, which is of course true, but in fact, high phosphorus and potassium fertilizer can also enhance the cold resistance of plants.

Even if bougainvillea doesn't bloom in winter, proper use can help it resist the cold and prevent the buds and roots from being frostbitten.

Taking potassium dihydrogen phosphate as an example (as are other high-phosphorus potash fertilizers), according to the ratio of 1: 1 0,000, the fertilizer powder is added into clean water and fully stirred to make a solution.

The root of bougainvillea bougainvillea was watered with this solution, and it was used every 7~ 10 days/time, and it had antifreeze effect after 2~3 times.

Step 4 control watering

Although bougainvillea doesn't grow as fast in winter as in other seasons, it still needs water to maintain its life activities.

In addition, it is dry indoors in winter. If it is not properly watered, the roots and branches of bougainvillea will dry up easily, which will affect the growth and flower quantity in the coming year.

Of course, you can't water it too much. If the roots absorb too much water, they will freeze or rot easily.

Watch carefully before watering bougainvillea.

When you find that the soil surface is white and dry, don't worry about watering it first, and then look at the leaves carefully.

Only when you see the leaves of bougainvillea are soft and wilting, and some droop slightly, it means that this plant is short of water, and then water it.

If the leaves are still standing and not wilting, even if the soil is dry, there is no need to water them.
