What Disease Causes the Yellowing of Rose Leaf Veins

When caring for roses, we may encounter the issue of yellowing leaf veins. What could be the reason? Let's find out below.

What Causes the Yellowing of Rose Leaf Veins

The mesophyll of rose leaves is green, but the veins are yellow. This is generally caused by root problems, and there is also a uniform yellowing of the leaves, which is physiological yellowing. If the veins are yellow but the mesophyll is slightly green, it should also be related to root problems. Yellowing in new leaves indicates severe issues with the capillary roots, while yellowing in old leaves suggests problems with the entire rose root system.

Methods to Treat Yellowing Rose Leaf Veins

Implement proper watering measures.

When rose leaf veins turn yellow, proper watering is essential. Water the plants only when the soil is completely dry, and when watering, make sure to water thoroughly. During the growing period, water frequently but avoid waterlogging. In cold weather, water less to keep the soil in the pot slightly moist, which can help the veins recover活力 and turn green.

Fertilize promptly.

During the rose growing period, fertilization should be carried out regularly. Insufficient nutrients can cause the veins to turn yellow. For example, during the growing season, ripe organic fertilizer can be applied every half month, and cake fertilizer water can be applied once a month before winter. After entering winter, no fertilizer should be applied.

Keep warm.

When the temperature is above 35℃ or below 5℃, the veins of rose leaves will turn yellow. Therefore, it is essential to maintain a warm environment when caring for roses. In summer, move the roses to a cool and well-ventilated place, and in winter, place them in a sunny spot or a heated area to avoid frostbite.
