What should be done if the grafted rose tree is always malnourished and has a yellow and thin appearance?
Here are some small knowledge about flower cultivation to answer netizens' questions on how to deal with the malnutrition and yellowing of grafted rose trees. Let's learn about it together.
What should be done if the grafted rose tree is always malnourished and has a yellow and thin appearance?
The rose tree has been malnourished. For grafted rose trees, how should they take root and apply fertilizer.
In this pot of grafted rose seedlings, the growth of the grafted seedlings mainly depends on whether the root system is developed. If the root system is poor, the growth will also be poor. Generally, if the root system of the grafted rose is not good, the degradation speed is very fast, branching, buds, and good growth will start, but later the root system spreads. Water and mineral elements decrease, and the root system degenerates more and more seriously, which is also a normal phenomenon. The rootstock used by netizens is grafted seedlings. This kind of grafted rose seedlings is very common, but the root system is poor, which is related to the mountainToad Lily. The original grafted seedlings have a poor root system.
Let's take a look at the pictures provided by the netizens:
From this photo, we can see:
When you look at the broken bark of the trunk, you will find that it is a mountainToad Lily, which is a typical grafted seedling of mountainToad Lily.
There are many branches in these two circles. We can see that the early growth was very good, but now it seems that the top is heavy and the bottom is light, without sensation. This is a clear ratio of roots that branches cannot reach. How wide the crown is, the roots are how wide. The obvious area of the crown is larger than the roots. This is a common disease of potted plants, and it is better to plant them in the field.
The position of the third circle seems to have weak leaves, obvious black spots, and yellowing, which are caused by insufficient nutrition and poor resistance.
Let's look at the second photo:
From this photo, we can see:
The top bud withers in a circle, the leaves are small and thin, which is typical malnutrition caused by.
There are small and weak branches at the position of the two circles, the leaves are small and smooth, the top of the leaves is yellow, there are black spots, which is typical malnutrition.
There are many branches in these three circles. The typical situation is that the root system is not developed, and there is insufficient water and minerals (G-Y).
Through analysis, we conclude that there are few and weak roots, early branching, rapid growth, leading to heavy head and light feet, resulting in insufficient nutrition, insufficient water sources, malnutrition, small and thin leaves, and yellowing.
How to maintain Chinese roses grafted with rose trees? Fertilization is not the purpose of rooting. It is recommended that netizens do the following:
1. Change pots
Now it is autumn, then we can change pots. It is not a good suggestion to have a pot with the same area as the rose tree crown. It is better to build a flower bed on the balcony than to plant the flower bed in the pot.
2. Control branches and trees to prevent overload
You know, the root system of the rose tree is poor. In order to prevent the top from being heavy and the bottom light, it is recommended to control the number of branches, prune weak branches, thin branches, and dense branches, maintain the vitality of the tree, and make the root system proportional to the crown.
3. Fertilize after the roots are established
The current potted rose grows so poorly that too much fertilizer is useless. Only after the roots are established, fertilizer can be applied, but not for a long time. After irrigation, compound fertilizer can be dissolved, pay attention to watering after watering, now mainly using nitrogen fertilizer to improve tree vitality.
The detailed explanation shared above on what to do if the grafted rose tree is always malnourished and has a yellow and thin appearance, hoping this article can bring you some help in green plant management!
