What to Do About Herbicide Damage on Roses? Teach You the Correct Remedies

Roses are a common flower in everyday life, with high ornamental value, and their appearance is very attractive, similar to that of roses. They are mostly planted in gardens, parks and other places. However, during the cultivation of roses, applying chemicals can cause herbicide damage. So what should be done about herbicide damage on roses?

1. What to do about herbicide damage on roses?

After herbicide damage occurs on roses, promptly move the plant to a cool, indirectly lit, well-ventilated place and spray the leaves with a large amount of clean water. Alternatively, spray the leaves with brassinolide to alleviate the herbicide damage. It is worth noting that you must not cut off all the leaves just because herbicide damage has occurred, because the remaining leaves can still carry out photosynthesis.

2. How to care for roses?

1. Pot and soil selection: There is no need to choose a fancy flower pot; an ordinary clay pot that drains and breathes well will do. Before using a new clay pot, soak it thoroughly with water first, then use it. For newly rooted cuttings, choose a small flower pot about 15 cm; for 1-2 year old rose seedlings, choose a flower pot 18-20 cm, gradually increasing the size according to the size of the plant. Roses like slightly moist soil and are very afraid of drought or waterlogging, so the soil must be loose, drain well, and also have a certain ability to retain water and nutrients.

2. Temperature requirements: The most suitable growing temperature for roses is 18-20°C, so in April-May and September-October each year, the flowers are larger and the colors are brilliant. As the temperature rises and stabilizes at around 30°C, the flowers become smaller in color, lighter in fragrance, and lower in ornamental value, and are susceptible to damage from pests and diseases. Under high or low temperature conditions, rose plants enter a dormant state and may show leaf drop, which is nothing to worry about.

3. Light requirements: Roses are sun-loving plants and need plenty of sunlight for growth. The daily light duration must not be less than 5-6 hours, otherwise the branches and leaves will be weak and leggy shoots will appear. Generally, for the care of potted roses, place them in a spot with plenty of sunlight, and in summer simply shade them and cool them down.

4. Cultivation precautions:

(1) Roses have strong cold resistance and can withstand low temperatures of -10°C. Generally speaking, in the south they can be placed directly under a south-facing eaves to overwinter, while in the north potted roses should be moved indoors to a ventilated place when the temperature drops below 10°C.

(2) After the flowers fade in October, do not prune; apply one application of decomposed phosphorus fertilizer to promote sturdy, well-filled branches and enhance cold resistance. In addition, when the temperature is very low in winter, water appropriately when it is slightly warmer to avoid the plant dying from dry freezing.
