How to grow gardenias in winter so they survive the cold safely
The gardenia is an ornamental flowering plant of high value, and it is grown on a fairly large area in China. Gardenias also have certain medicinal value and are welcomed by many people. So there are still quite a lot of people growing gardenias today, and when growing them, management must be strengthened once winter arrives to ensure they survive the winter safely. So how should gardenias get through winter? Let's take a look together below!
1. Temperature control
If you want gardenias to survive winter safely, then temperature control is certainly the first thing to get right. Although gardenias have a certain degree of cold tolerance, the temperature must not drop below zero degrees at the lowest. In the winter in the south, because winter temperatures are not very low, they can mostly be planted in the ground outdoors. But if you are in the north, then you must be sure to do a good job of cold protection and insulation, and the temperature should be kept above 5 degrees. This ensures that gardenias can safely overwinter and grow normally in winter, avoiding cold damage that lowers their survival rate.
2. Light control
Light is very important for the growth of gardenias. Gardenias need a large amount of light during their growth process, and winter is naturally no exception. And because the natural light hours decrease in winter, we must pay even more attention. While keeping gardenias warm in winter, you should also pay attention to maintaining suitable light; the plants can be given direct sunlight, and the daily light duration should be kept at at least six hours or more. Moreover, letting gardenias receive sufficient sunlight in winter not only meets their light needs but also raises the temperature.
3. Reduce watering
During the growing season of gardenias, water is naturally an indispensable substance. Gardenias also like to grow in a humid environment, but after entering winter, because gardenias gradually enter dormancy, their growth rate slowly declines. Therefore, watering should be appropriately reduced; if watered too much, the gardenia roots cannot absorb it, which leads to root rot, lowers soil temperature and so on, and instead affects the gardenia's overwintering. So in winter, watering should only be done after the soil has dried out, and in the relatively dry winter environment, you can appropriately spray a little water on the leaves.
4. Reasonable fertilizing
When growing gardenias, fertilizing is also indispensable. Reasonable fertilizing can meet the growth nutrients gardenias need and increase the flowering rate and flower quantity of gardenias. But this is only done during the growing season of gardenias; in winter, because the growth rate of gardenias is extremely slow, the demand for fertilizer is very low, and basically no fertilizing is needed. If you fertilize blindly, the gardenia cannot absorb it, which not only wastes fertilizer but may also cause fertilizer damage to the plant, seriously affecting the growth of the gardenia.
The above is a brief introduction to how gardenias get through winter. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
