Yellowed leaves of indoor plants. All the reasons for their appearance
There are many reasons and factors that can affect the health and appearance of a plant. But in order to determine what the problem is, we need to take the time to solve it. Even after you fix the problem, the yellow leaves may fall out in the meantime. If the plant stops hurting, it is possible that new leaves will grow during the next growing season.
6 reasons for yellow leaves:
1. Moisture - stress
Over-watering or insufficient watering is a fairly consistent cause of yellow leaves in a plant. For plants that are in a pot, watering should be selected individually for each species. If you notice that yellow leaves have appeared in a houseplant, then check the condition of the soil in the pot - is it dry? Or wet? When a plant does not get enough water, leaves fall out, thus it prevents evaporation (the way plants sweat) to conserve water. However, the leaves usually turn yellow before falling out. If at that moment the soil is dry, then you need to make a regular watering schedule for the plants.
And too much water is also not safe for the leaves, and the soil becomes too wet and the root system can literally drown, without the supply of oxygen, the roots begin to die off.
2. Normal aging
In many plants, as they age, the lower leaves turn yellow and begin to fall out, so this is the normal phase for their growth. In this case, the plant visually becomes too long-legged, it is then that you should think about cutting the main stem in order to stimulate new growth and bushiness.
3. Not enough light
The appearance of yellow leaves is also a lack of sunlight, that is, they receive too little of it. A yellow color already appears on the lower leaves, even before they fall out. There is an answer to this question:
Due to the lack of light, the plant usually turns yellow on the far side of the light source. For example, the leaves by the window receive all the light and cover the opposite side. A great way to fix this is to not turn the pot over once a week so that natural light can be accessed from all directions.
In this case, you need to move the plant to more sunlight and monitor its condition. And if the house does not have enough window light, especially in winter, then you need to think about installing an artificial one.
4. Cold draft
Cold drafts can lead to loss and yellowing of leaves, especially in the form of tropical indoor plants, and even short-term severe cold can affect this, then the health of the leaves will deteriorate: the color will darken and pale transparent spots appear between the veins.
5. Nutrient deficiency
Yellow leaves can also be caused by a lack of essential nutrients for the plant. This can be caused by too much calcium in the water if hard water is used, or a nitrogen deficiency.
6. Viral infection
Spotted yellow spots on leaves in plants are a sign of a viral infection, this can be accompanied by deformation of leaves and stems, as well as discoloration of flowers. This disease is curable and incurable, it spreads the infection to plants that are nearby. The plant urgently needs to be quarantined, away from others. Check nearby plants to make sure spread is limited. You can take steps to save the plant, but you must first try to identify the virus. Some remedies may include fungicides, while others may require the removal of healthy parts and propagation.
While it can be painful, if you are a favorite, you may have to give up favorite plants that you cannot bring back to health. Wash and sterilize all pruning tools or pots before using on other plants.
