What to do if the leaves of Rhododendron turn yellow

1. Long-term lack of light

Rhododendron hairy is relatively more fond of light. Many people do not pay much attention when growing flowers at home and place the flowers in places where there is not enough light. We know that green plants achieve energy conversion by absorbing sunlight. If they are not exposed to enough sunlight for too long, it will lead to the lack of certain substances in the leaves of the plants, causing the leaves to turn yellow.

Solution: Place the potted azalea in a location with good sunlight.

2. Unreasonable temperature

This point should be paid special attention to in winter. The growth of any plant has a temperature limit. Therefore, when caring for it, the growth temperature of Rhododendron hairyense should be strictly controlled to prevent the spread of frost damage, so as to prevent the symptoms of yellowing leaves!

Solution: Pay attention to maintaining the room temperature, which should be above 10 degrees Celsius. In autumn and winter, when the outdoor temperature is low, bring the flowers indoors in time.

3. Improper watering

It likes a well-drained substrate, and too much water will also cause yellow leaves. This is because when there is too much water, it will hinder the physiological respiration of the flower roots, causing damage to the plant roots. When there is a problem with the roots, nutrients cannot be transported normally to the stems and leaves of the plant, resulting in yellow leaves. In addition, untimely water replenishment will also cause the plant to lack water, causing the leaves to turn yellow and dry.

Solution: Water scientifically and reasonably, it is best to water when the soil is dry and then water when it is wet.

4. Too much or insufficient fertilizer

Fertilizer is also a vital part of the growth of this flower. Too concentrated fertilizer is likely to burn the roots of the plant, causing damage to the flower roots, which will manifest as yellowing on the leaves. The lack of nutrients can also cause yellow leaves.

Solution: Measure the amount of fertilizer according to the size of the plant. It is best to dilute the fertilizer before applying.

5. The air is too dry

Sometimes, especially in the north in winter, the indoor environment is relatively dry, and yellow leaves will appear at this time, so it is also important to maintain appropriate indoor humidity.

Solution: Spray some water around the potted plants, or place a basin of water around the flowerpots to adjust the air humidity nearby!
