Recently, many flower enthusiasts have been consulting about the problem of yellow leaves on roses, and they find that the leaves of the roses they bought turn yellow after a short period of care. Many flower enthusiasts feel helpless and do not know what to do.
Most of the yellow leaves of potted roses are due to the following reasons, and we can accurately respond by distinguishing the causes of yellow leaves.
1. New leaves turn yellow
There are many situations where the leaves of roses turn yellow, and some enthusiasts find that the new leaves turn yellow while the old leaves are normal. The usual causes for new leaves turning yellow are as follows.
Overwatering
Many novice enthusiasts cannot grasp the watering of roses and often overwater them, resulting in waterlogging and showing yellow new leaves.
If your rose turns yellow in new leaves while the old leaves are normal, and the potting soil is often moist, you should consider overwatering. Just pay attention to controlling the watering and water the plant when the soil is dry.
Iron deficiency yellow leaves
Roses prefer slightly acidic to neutral soil, and enthusiasts growing roses in the northern regions need to pay attention to the problem of soil alkalization.
Soil alkalization can affect the absorption of iron by roses, resulting in yellow new leaves.
When soil alkalization causes roses to have yellow leaves, just add a little ferrous sulfate to the roots while watering each time. This can supplement iron and also adjust the soil pH.
2. Old leaves turn yellow
In addition to new leaves turning yellow, old leaves of roses often show yellowing.
