Can dead elm leaves live?

Ulmus pumila can withstand low temperature, but some experts say it can accept the low temperature of minus five or six degrees, and it is not easy to be frozen by frostbite when it is placed outdoors. Actually, that's what I mean, but if you want it to grow better, don't try it like this. In the south, only warm cities can follow this method. In the northern region, if the outdoor temperature is below zero, it will definitely be frostbitten or even frozen to death.

At this time, we will put it indoors. When the temperature is lower than 15 degrees, the leaves will definitely turn yellow, so don't worry. To solve the problem, raise the indoor temperature and keep it at a temperature suitable for its growth. If you want it to continue to grow in winter, you can put it in a heating room at this time. When the temperature is above 20 degrees, will there be fallen leaves? The growth is quite strong.

Second, the problem of fertilizer and water.

When I first moved indoors, when the temperature was 15 degrees, there were yellow leaves. At this time, it is necessary to check the fat water. The temperature above 15 degrees is not much different from that in early spring. It is necessary to control the fertilizer and water according to its growth habits. Don't water it too much. Water it about once every three days. Secondly, avoid water accumulation, otherwise there will be rotten roots and yellow leaves falling off. In fact, as long as the soil is in a state of maintenance, it can not only ensure good growth, but also avoid yellowing and withering of leaves.

When the temperature exceeds 15 degrees, some fertilizers can be used at this time, but the concentration is thinner than usual, because although it can continue to grow at this time, its absorption capacity will be poor. If the concentration is too strong, it will definitely produce yellow leaves. Generally, he fertilizes once every 20 days and just adds some water.

Third, the lighting problem.

The growth environment of warm sunshine conforms to the habit of Ulmus pumila, which needs sufficient light to effectively carry out photosynthesis, transform energy in the body and stimulate more chlorophyll, so that the longer the leaves are, the greener they are. Generally, when moving indoors, at least four hours of light should be guaranteed every day. If the sunshine time is not enough, it is easy to have yellow leaves and dead leaves. It's rather dry today. After being exposed to sunlight, water will evaporate quickly. At this time, it is necessary to spray some water to ensure the humidity of the surrounding environment, so that the lobular elm can grow beautifully.
