What if the magnolia doesn't grow leaves?

Cymbidium is not only a very common plant in our daily life, but also the city flower of Changchun, China, which has high ornamental value, so there are many people who plant it. But in the process of planting magnolia, some people will encounter the situation that magnolia does not grow leaves, how is this going on? Next, the pro-agricultural network will introduce to you what to do if the magnolia does not grow leaves.

First, the reason why the magnolia does not grow leaves

If we want to know what to do if the orchid does not grow leaves, first of all, we have to find out why the orchid does not grow leaves. Here, the pro-agriculture network summarizes three reasons, including rotten roots, inappropriate soil, and the effects of diseases and insect pests. Let's take a look at it in detail.

1. Rotten root

One of the reasons why Cymbidium does not grow new leaves is that there may be rotten roots, which, as the name implies, is rotten, which will lead to insufficient supply of nutrients and can not provide the necessary nutrients for the growth of Cymbidium. So the new leaves can't grow.

two。 The soil is not suitable

If the magnolia just brought home to change the pot has not grown new leaves for a period of time, it may be that the newly changed soil is not suitable for the growth of magnolia, such as excessive alkalinity, which will inhibit the growth of the root, so that the root can not absorb nutrients, and the leaves will not grow new.

3. Diseases and insect pests

The invasion of diseases and insect pests is inevitable in the process of breeding, especially the emergence of insect pests, pests will eat the budding parts of the orchid or the young leaves that have just grown, so that the new leaves will not grow out.

Second, what if the magnolia doesn't have leaves?

1. Treatment after rotten roots

If the rotten roots have already occurred, we need to remove the pots, cut off the rotten roots and change the soil for cultivation. After cutting the rotten roots, the magnolia can be soaked in the rooting powder to let the roots grow as soon as possible.

two。 Soil acidification

Cymbidium is more suitable to grow in acidic soil. If the soil is too alkaline, you can pour some ferrous sulfate solution into the soil or dilute the alkalinity of the new soil with diluted edible vinegar solution, and new leaves will grow again after a few days.

3. Spray medicament

As the new leaves are eaten by insects, we can only get rid of the insects first and then wait for the new leaves to grow. The easiest way to get rid of the insects is to spray them with corresponding insecticides, and it is best to prune the branches with diseases and insect pests.
