A popular plant that adorns the interior is geranium. She is undemanding in leaving and even possesses curative properties. A century and a half has passed since geraniums made room. This plant pampers us with flowers almost all year round and, according to beliefs, protects the house from evil spirits. Why do geranium leaves turn yellow? Let's figure it out.
Why do the leaves of a room geranium turn yellow?
Despite the fact that geranium has more than one hundred varieties, the rules for caring for them basically do not differ:
- A room with room geraniums should be well ventilated and light enough.
- The mixture of soil should be well drained, loosened, neutral acidity. The soil for planting is purchased in the trade network or prepared by mixing black soil with sand and turf. Geranium is best grown in small pots - so you can enjoy its flowering longer.
- In the summer, the soil in the pot should be fertilized. It is necessary to make mineral substances weekly.
- When flowering need more frequent watering, but avoid excess moisture. The plant does not need to spray the leaves, this procedure is necessary only for diseases. In winter, soil moisture should not be abundant.
Why do geraniums turn yellow and dry leaves? This condition of the flower may indicate its disease, which is usually associated with violation of the rules of care:
- The lack of light causes not only the drying of leaves and new shoots, but also slower growth, as well as the absence of flowering.
- Excess moisture or poor drainage:
- leaves fade;
- brown spots appear on their tips;
- in the end, they turn yellow and fall off;
- growth is slow;
- roots rot.
- Too narrow pot:
- new leaves are very small;
- old ones turn yellow and fall off;
- the plant quickly fades;
- roots stick out of drainage holes or grow near the soil surface.
- Lack of fresh air, poor ventilation.
- Lack of moisture, the soil is hard and dry:
- leaf wilting;
- the flower grows slowly;
- brown spots develop on the periphery of old leaves and, eventually, turn yellow and fall off.
- Air temperature too high:
- the stems lengthen and become thinner, despite proper lighting;
- older leaves wither, even if they have enough moisture and eventually turn yellow-brown before they fall.
- Excessive drop in air temperature. The plant tolerates a temperature drop of no lower than + 8 ° C. That is why geranium leaves turn yellow in winter and fall off a few hours after it undergoes a sudden change in temperature.
- Excessive accumulation of salts in the pot soil due to alkaline water:
- leaves turn yellow-brown, like in autumn, and fall off;
- a white crust forms on the soil surface.
The culprits of yellow leaves and wilting geraniums can be viruses, which are usually brought from other plants or infected soil mixture. To eliminate this risk, it is necessary to sterilize the soil during transplanting the geranium. The greatest danger is represented by plant nematodes. When this disease is introduced into the soil, it cannot be used for other plants.
How to save geranium from withering?
The above signs of wilting geranium, yellow and dry leaves on it, you can use to diagnose and find out the specific cause of these troubles. In accordance with the established reason, the necessary measures are taken to save the beloved plant.
Geranium tolerates a drier soil than excess moisture. That is why the pots must be well drained and retain a small amount of moisture. Geraniums are often found in filled and swampy saucers. Water the flower always on top of the soil, and then drain all the excess from the dish. If this condition is not met, the geranium leaves will begin to fall off. With a lack of moisture, increase the amount of watering the plant.
Geraniums love the sun, but its influence should not be too intense. When placed in places where the light is very bright, geranium leaves become yellow-red, and the old ones are affected first. Place indoor plants in areas where they will be provided with shade in the afternoon, when sunlight is most intense.
In case of a lack of light, increase the natural or artificial light at the first sign of fading. Reduce the temperature in the room by 3 ° C. Reduce watering and stop feeding.
The fast-growing geraniums have small root systems that are vulnerable to phosphorus and trace element deficiencies. Therefore, it is necessary to feed the plant with liquid fertilizer with a high phosphorus content every two weeks during the growing season. For example, a tablespoon of soluble fertilizer must be diluted in 3 liters of water to compensate for nutrient deficiencies and stimulate proliferation.
And a few more important tips:
- When the room is too hot, avoid direct sunlight on the plant in the summer or remove it from heat sources in the winter.
- Remove damaged leaves to prevent disease outbreaks.
- To avoid salt crust on the soil, let the water stand for 24 hours before watering.
With proper care, geranium will delight you with its flowering almost all year round. Good luck to you!
