Rhododendrons and camellias bloom very beautifully, but in maintenance, the most prone to leaf loss, so that many new flower farmers are helpless, so what causes rhododendrons and camellias to lose their leaves? And how to solve it? The following is to share years of maintenance experience for the reference of flower lovers.
<h1 class="pgc-h-arrow-right" data-track="2" >1, improper use of potting soil</h1>
Rhododendron and camellia root system are relatively short, the growth period needs to be loose and breathable micro-acidic humus soil, generally the earth, vegetable garden, road edge, viscous, alkaline and other soils are not suitable for their growth, the root system is prone to problems, the root system is a problem, the leaves will wither and fall.
Solution: Replace with breathable slightly acidic humus or special soil, and drop two drops of vinegar into the water every month when watering, so that the water becomes slightly acidic, which helps to regulate the soil and can also play a role in sterilization and disinfection.
<h1 class="pgc-h-arrow-right" data-track="5" >2, ambient humidity is not applicable</h1>
Rhododendron and camellia like humid air environment, especially in the arid areas of the north, if the breeding environment is too dry, it will be greatly damaged to the leaves, easy to cause dry and shedding. On the contrary, if the ambient humidity is too large, it is also easy to cause leaf drops, and it is also easy to cause rotten roots and diseases and insects
Solution: Dry weather, pay attention to the surrounding water often sprayed to humidify, increase the environmental humidity, rainy weather should pay attention not to too much rain, and to keep the soil can not be too wet.
<h1 class="pgc-h-arrow-right" data-track="8" >3, soil is too dry or too wet</h1>
Excessive watering of the soil or forgetting to water, resulting in too much humidity or too much dryness, will cause the leaves to fall off, and in severe cases, it may also cause large leaves to fall off or rot roots, preferably leading to wilting or drying.
Solution: Watering should be based on the soil and weather to determine the frequency of watering, and do not randomly water, in accordance with the watering law of not dry and no watering, to prevent excessive soil moisture and lead to root rot.
<h1 class="pgc-h-arrow-right" data-track="11" >4, the environment is too hidden</h1>
Rhododendron and camellia like semi-shaded environment, especially indoor maintenance, due to weak light, can not meet the photosynthesis of the leaves, resulting in leaves can not produce the nutrients needed for growth, at this time the petiole will be separated from the plant, resulting in a large number of leaves, especially in the case of soil moisture, insufficient light, the phenomenon of leaf fall is very serious.
Solution: Indoor farming to move it to a place with sufficient light, especially in the spring and winter, must maintain sufficient light.
