What symptoms appear when a rose is over-fertilized?

When a rose is over-fertilized, it causes the branches and leaves to turn yellow and dry up. If the fertilizer burn is relatively severe, it leads to a large number of leaves dropping, the root system being burned, and eventually death. In cases of severe fertilizer burn, you should promptly repot it, replace it with fresh potting soil, and place it in a cool spot so it can recover as quickly as possible.

Over-fertilizing roses causes yellow leaves and burned roots

When a rose is over-fertilized, it causes the branches and leaves to turn yellow and dry up. If the fertilizer burn 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 is applied, it must be dealt with promptly to avoid the death of the rose.

I. Solutions

When the over-fertilization of a rose is not too severe, you can dilute the fertilizer by watering so it flows out from the bottom of the pot. If the over-fertilization is relatively severe, you can deal with it by repotting: take the original plant out of its pot, replace it with fresh potting soil, and follow the principle of applying light fertilizer frequently.

II. Fertilization methods

1. During the growing period, roses need regular fertilization. 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 to meet the requirements for growth and flowering the following year. Before flower buds appear, you can apply a top dressing of 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 once a relatively concentrated decomposed cake fertilizer water. During the winter dormant period, do not apply fertilizer. Each fertilization can be done in clear weather: first loosen the soil a little, and wait until the soil is slightly dry in the evening to do it, which helps the rose absorb the fertilizer.
