【Solutions for Root Rot in Roses】

Firstly, the rose plant needs to be dug out from the potting soil and soaked in water to clean off the dirt. After disinfecting the scissors, you can cut off the decayed roots of the rose plant. If the rot is severe, you can spray the roots with carbendazim or thiophanate-methyl to effectively prevent continuous root rot.

If you still want to use the original pot after pruning, you should remove all the original potting soil and disinfect the pot, then replace it with new, loose, and breathable soil. Plant the plant, which has been soaked in carbendazim, into the new soil and place it in a shady and well-ventilated area. Water thoroughly after two days.

When the rose plant is severely lacking in water for a long time, its roots will gradually rot. Therefore, when rot is detected, water promptly and cut off the roots. However, watering should be done "when dry and wet," and it should not be done blindly.

Over-fertilizing the rose plant can easily cause fertilizer damage and lead to root rot. When fertilizing, if there is too much fertilizer, dilute the potting soil to let the excess fertilizer flow away with the water. Use nitrogen and potassium fertilizers as the main fertilizers, with decomposed cake fertilizer being the best choice.

When the air and soil temperatures are high, the nutrient function of the tip of the fleshy roots is damaged and rots, preventing water and nutrients from reaching the leaf tips, which can cause leaf tip necrosis. The optimal growth temperature for roses is 12-28 degrees Celsius, with a minimum tolerance of -20 degrees. Moving the rose plant to a suitable environment will gradually lead to improved growth and recovery.

If the potting soil has not been changed for a long time, it is necessary to repot and also prune the branches and leaves intensively. Sometimes, to ensure survival, 80% to 90% of the branches and leaves need to be cut. During the plant's recovery process, keep the potting soil moist, regularly spray water on the dry branches, avoid fertilizing, and prevent the potting soil from getting rain to avoid further root rot.
<Conclusion>
When a rose plant has rot, there is no need to panic. In fact, the plant can be saved with reasonable methods. Therefore, it is important to identify the cause promptly and solve the problem to make the rose plant recover its vitality and grow more vigorously.
