How to remedy yellowing leaves?

In the process of potted plant maintenance, the leaves of potted plants at home often turn yellow due to unknown reasons. When faced with this situation, many friends will be at a loss. So how to remedy the yellowing of leaves? Let’s take a look below.

1. Burning yellow

Symptoms: Some leaf tips of plants at home turn yellow or burnt.

Cause: Some plants that prefer a cool environment are placed in direct sunlight, resulting in the plants being exposed to strong sunlight.

Solution: You must fully understand the habits of the plants. For plants that do not like sunlight, such as spider plants and evergreens , they must be placed in a cool, humid place.

2. Albino yellow

Symptoms: The branches and leaves of some plants were found to be turning yellow and white.

Reason: The plants are kept in a dark place all the time. They cannot receive sunlight, resulting in insufficient light. The chlorophyll in the leaves gradually decreases, and the branches and leaves gradually turn yellow and white.

Solution: At this time, the plant should be moved outdoors so that it can receive sufficient sunlight.

3. Alkali yellow

Symptoms: The new leaves turn from green to yellow, but the veins of the leaves are still green. The leaves are yellow and green, and the difference is very obvious. If no timely measures are taken after this happens, the veins of the new leaves will gradually turn yellow, the edges of the leaves will wither and fall off, and even the plant may die.

Reason: For some plants that like acidic soil, such as osmanthus and azalea, the soil in the pot is alkaline or the water used for watering is alkaline.

Solution: Acidic fertilizers or acidic substances can be applied to improve the situation.

4. Damp-heat yellow

Symptoms: Large areas of leaves of some plants turn yellow and wither.

Reason: For some plants that are not tolerant to moisture and heat, there is poor ventilation and no shading or water control.

Solution: The yellowing phenomenon of this plant is easy to solve. Just make sure to keep the indoor ventilation smooth, pay attention to shading and water control when the temperature is too high, and try to keep the soil in the pot dry.

5. Low temperature yellow

Symptoms: Some cold-sensitive plants, such as white orchid and poinsettia , will have yellowing leaves or fall off when the indoor temperature is low or cold.

Cause: In the cold winter, the indoor temperature is too low.

Solution: Be sure to understand the habits of potted plants and make insulation preparations in advance when winter comes.

6. Fat and yellow

Symptoms: The new leaves are relatively thick and shiny, but the surface of the leaves is uneven, and the tips are dry brown. The old leaves gradually turn yellow and fall off, and the tips of the leaves appear burnt yellow and dry.

Reason: Most of the time it is because the plants are fertilized too much or the concentration is too high, especially when nitrogen fertilizer is used too much.

Solution: Stop fertilizing at this time and increase watering appropriately to dilute the fertilizer content in the soil.

7. Hungry Yellow

Symptoms: The roots of the potted plants are clumped together, the stems of the new leaves turn yellow first, and then the whole plant turns yellow or even dies.

Cause: Potted plants at home have only been watered but not fertilized for a long time, or the pots have not been changed for many years, there is insufficient fertilizer, the fertilizer concentration is too low, and the interval between fertilization is too long.

Solution: Be sure to replace the flower pots in time, apply fertilizer frequently, and apply thin fertilizers. And for this kind of fertilizer-deficient plant, remember not to apply too much fertilizer at one time to avoid burning the plant roots.

8. Water yellow

Symptoms: Generally, the old leaves of the plant do not change significantly, the new leaves turn yellow obviously, wither and dull, and the stems become thin and yellow.

Cause: It is mainly due to excessive watering and excessive water volume, which leads to excessive water accumulation in the pot, lack of oxygen in the soil, root rot of potted plants and poor soil water absorption capacity.

Solution: When this happens, you should loosen the soil immediately, control watering significantly, and stop fertilizing. If the situation is serious, you can take the plant out of the pot, put it in a cool place to dry the moisture at the roots of the plant, and then put it back in the pot.

9. Dry yellow

Symptoms: The leaves turn yellow or the edges turn brown, there is no obvious change in the new leaves, the old leaves turn yellow from the bottom to the top, and some old leaves may fall off.

Cause: The plants have not been watered for a long time or have been watered too infrequently.

Solution: Replenish the water of the plants in time, increase the amount of water or increase the watering frequency.

That’s it
