Analysis of the Latest Symptoms of Over-Fertilizing Roses

When roses are over-fertilized, it causes the branches and leaves to turn yellow and dry up. If the fertilizer damage is relatively severe, it leads to a large number of leaves dropping, the root system being burned, and ultimately death. In cases of severe fertilizer damage, we must promptly repot them, replace the soil with fresh growing medium, and place them in a cool spot so they can recover as quickly as possible.

Over-fertilizing roses causes yellow leaves and burned roots

When roses are over-fertilized, it causes the branches and leaves to turn yellow and dry up. If the fertilizer damage is relatively severe, it leads to a large number of leaves dropping, the root system being burned, and finally the plant dying. So if too much fertilizer has been applied, it must be dealt with promptly to avoid the situation of the roses dying.

1. Solutions

When the over-fertilization of roses is not too serious, you can dilute the fertilizer by watering, letting it flow out from the bottom of the pot. If the over-fertilization is relatively serious, you can repot the plant, taking the original plant out of its pot, replacing it with fresh growing medium, and following the principle of applying thin fertilizer frequently.

2. Fertilizing Methods

1. During the growing period, roses need to be fertilized regularly. Apply decomposed organic fertilizer once every half month; in addition, when repotting in spring, you can bury 100 grams of decomposed cake fertilizer in the flower pot, so as to meet the requirements for growth and flowering the following year. Before the flower buds appear, you can apply a supplementary phosphorus and potassium fertilizer, and add a 0.003% potassium dihydrogen phosphate foliar fertilizer once a month.

2. Before the Start of Winter, you can apply a relatively concentrated decomposed cake fertilizer water once; during the winter dormant period, do not apply any fertilizer. Each fertilizing can be done when the weather is clear, first loosening the soil a little, and waiting until the soil is slightly dry in the evening to do it, which helps the roses absorb the fertilizer.
