Rhododendron is one of the top ten famous flowers in China. It has luxuriant branches and bright flowers. It can be made into a variety of shapes and has high ornamental value. Rhododendron farmers all know that it is easy to blacken the leaves in summer, but they all fall off in the end, but I don't know why, so let's introduce the reasons and its solutions.

Moisture content

The summer weather is relatively hot, the rate of evaporation must be faster than before, if it has not been watered for a long time, it will make the leaves black and fall. Then we have to trim the leaves off and water them slowly, but not too much until it returns to normal.

Although azaleas like humid environments, too much watering will also cause stagnant water, root system will rot, resulting in leaves blackening and falling. Then we have to take it out of the basin, trim off the rotten roots, then put it back on the basin, raise it in a cool and well-ventilated environment, and wait for normal maintenance after taking the basin.

Ventilation

The summer weather itself is relatively hot, if coupled with no ventilation, it will make the edge of the leaves dry, and finally slowly fall. So if you cultivate azaleas in summer, you need to raise them in a well-ventilated environment, then take off the charred leaves and spray clean water around them.

Light

Rhododendron peanuts like plenty of light, but the summer light is relatively strong, if it is irradiated by strong light for a long time, it will burn the leaves and cause black spots to wither. So when the light is strong in summer, it can be raised in a cool and well-ventilated place.

Fertilizer

Cuckoo peanuts are fond of fertilizer, but if the concentration of fertilizer is too high in summer, the roots will burn out, the leaves will turn black and curl, and die directly in the end. Then we should immediately water the azaleas thoroughly and a few more times, so that the fertilizer will follow the water, then prune most of the branches and put them in a cool and well-ventilated place.
