What to Do When Rose Leaves Turn Yellow and Fall Off Easily to Grow New Buds
Roses, also known as "Monthly Red," are called the queens of flowers, and 52 cities in China have chosen roses as their city flowers. Roses bloom all year round, with flowers usually in red or pink, possessing high ornamental and medicinal value. However, leaf drop can occur during maintenance, which is a problem that troubles many flower enthusiasts.
Rose leaves turning yellow and falling off may be caused by excessive watering, which leads to root rot, or by diseases and pests. It could also be due to improper fertilization and lack of timely pruning. Let's talk in detail about the causes and solutions for rose leaves turning yellow.
Improper Watering
① Cause
When roses show symptoms like leaves turning yellow and falling off easily, it is likely caused by improper watering. This is manifested in yellowing branches and rotting roots. Therefore, when watering roses, follow the principle of "not watering until dry, and watering thoroughly when watering."
② Solution
If this situation occurs, it is necessary to cut off the severely yellowed leaves and severely decayed roots, and disinfect them to prevent further infection. The mildly decayed parts can be cared for by piling soil at the base of the plant.
So, when we feel that the roses we are caring for have been watered too much, we can place the plant in a ventilated area until the soil is completely dry before proceeding with the next step of maintenance.
Disease
① Cause
If roses are infected with fungal leaf spot pathogens or powdery mildew, it will directly cause leaves to turn yellow and fall off, affecting the healthy growth of the rose. In severe cases, the leaves will not expand, and the branches and leaves will die due to the inability to perform photosynthesis.
② Solution
When roses are infected with a disease, they can be treated by spraying specialized medication for fungicide. The pathogen starts to infect from May and July to August is the peak period.
When caring for roses, we can protect them by spraying 0.3-0.5 degree lime sulfur solution once a week for two to three weeks. During the peak period, we can spray a 40% ferbam wettable powder solution (500 times dilution), continuously spraying for three weeks, once a week.
Improper Fertilization
① Cause
Rose leaves turning yellow and falling off, with small flowers and weak flowering branches, may be caused by improper fertilization. It is necessary to supplement new fertilizers for the elements that the rose lacks.
② Solution
Fertilization should follow the principle of applying thin fertilizer frequently. Dilute the fertilizer before application to prevent fertilizer damage. For base fertilizer, it is recommended to choose decomposed fertilizer, and avoid applying undecomposed organic chemical fertilizers, as this may burn the plant's roots.
Improper Pruning
① Cause
Improper pruning of roses can also cause leaves to turn yellow and fall off easily. Pruning can be done during the growing season and in winter. During the growing season, it is necessary to cut off the flower stems and withered branches after flowering, leaving 8 to 12 buds.
② Solution
In winter pruning, to promote better absorption of nutrients, it is necessary to cut off the dead branches and leaves. The principle of pruning is to cut off the diseased and withered branches, and also prune the dense areas to allow the rose to grow in a well-ventilated environment.
Temperature Factors
① Cause
Sudden changes in temperature are a common cause of rose leaves turning yellow and falling off. Abruptly hot and cold weather can put stress on the growth of roses, leading to yellowing of the leaves.
② Solution
We can cover the soil surface with a mulch, such as decomposed wood chips. When growing roses, ensure they receive more than six hours of sunlight daily. Prune the plant in a timely manner to maintain a comfortable growing environment.
