What are the reasons for the yellowing of flower leaves?
Today's sharing: reasons for the yellowing of flower leaves and the related knowledge of plant yellow leaf treatment, next, the editor of this site will introduce to everyone.
There are many reasons for the yellowing of plant flower leaves, for example, common indoor environments that are too dark, long-term water deficiency, or excessive frequent watering can all cause leaves to turn yellow. Let's analyze several situations of yellowing plant leaves and how to deal with them?
1. Yellowing at the tip of the leaves
This situation is very common. The leaves look green overall, but the tip of the leaves turns yellow and withers, and the tip will turn brown or yellow. This is usually because the humidity of the air around the plant is insufficient or there is a layer of dust accumulated on the leaves, which needs to be cleaned.
Timely clean the leaves. If the leaves have fine hairs, you also need to use some soft brushes for cleaning. Also, pay attention to timely supplementing the plant with some organic fertilizer water, the concentration should not be too high, just a little thin fertilizer is fine.
2. Lack of nutrient elements
When growing potted plants at home, if you water the plants frequently and always use tap water, it can easily lead to yellowing of the plant leaves, which is caused by soil alkalinity.
There are also some cases where the yellowing is due to a lack of nutrient elements, for example, common flowers like gardenia, camellia, and jasmine all prefer acidic soil. If the soil lacks iron or zinc elements, it will cause the newly grown leaves to turn yellow, not because they are young and tender but due to a lack of nutrients.
You can directly supplement the plant with some acidic fertilizer and trace elements, or common ferrous sulfate solution.
3. Yellowing leaves due to excessive shading
For potted plants cared for indoors, there is another situation that is particularly prone to causing yellowing of leaves, which is keeping them in a dark place for a long time. Many plants are very shade-tolerant, such as common aspidistra, money tree, and tigereye. They can be kept in a cool place, but this does not mean they can be kept in the dark for a long time.
If you find that the leaves of the plant start to turn yellow and wither after being kept in the dark for one or two weeks, you should cut off all these yellow and withered leaves and only need to restore light to them. Be careful not to expose them to direct sunlight all at once; you should slowly add light, otherwise, the leaves may be sunburned.
4. Yellowing of old leaves
When growing potted plants, if you find that the bottom of the plant stem keeps producing yellow leaves and only a few old leaves are yellow, this is also very normal and depends on different conditions. If it is a potted plant that has been grown for a long, and there is a small amount of old leaves at the base of the stem turning yellow, it is a normal metabolism and does not require much attention. Just clean up the yellow and withered leaves in time, and there won't be any problems.
If a large number of old leaves show yellowing, it is necessary to supplement the plant with nutrients in time. You can add some fertilizers with a higher nitrogen content or balanced fertilizers, and make sure there is no fertilizer residue on the leaves.
5. Lack of magnesium element
