What is the Reason for the Yellowing of Rose Leaves and What Are the Treatment Measures
Why Do Rose Leaves Turn Yellow
Roses come in a variety of colors and shapes and are now commonly seen in road greening, rural fields, and garden landscaping. Roses prefer to grow in environments with plenty of sunlight, warmth, and ventilation. During our daily maintenance, it is common to see leaves turn yellow, which is often caused by improper water and fertilizer management.
1. Roses are highly sensitive to water, intolerant of waterlogging, and cannot be in a dry environment for long. Excessive moisture in the soil will turn the tender leaves yellow, while the changes in old leaves are not obvious, and new shoots will become atrophied. Long-term water shortage will cause the leaf edges to dry out, and old leaves to turn yellow.
2. Roses prefer to grow in loose, breathable, and fertile slightly acidic soil. If the soil pH is not suitable or the soil is compacted, it will cause the leaves to turn yellow, even if the soil pH is appropriate, and the concentration of applied fertilizer is high, or fertilizer is close to the roots, it will burn the roots and cause the leaves to turn yellow.
What to Do When Rose Leaves Turn Yellow
1. Watering during the rose growing period should be moderate, with slightly moist soil being best. If excessive watering leads to waterlogging, it should be moved to a well-ventilated area immediately, frequently loosening the soil to evaporate the water, or directly removing the pot, drying the soil clump, and replenishing water when the soil is too dry.
2. Attention should be paid to the management of rose fertilizer, applying it frequently in small amounts. If excessive fertilizer is applied at one time, it should be diluted with clear water and the pot should be raised to drain the fertilizer solution.
The above is a comprehensive introduction to why rose leaves turn yellow and what the treatment measures are, hoping to bring some green plant knowledge to green plant enthusiasts.
