How to prune climbing roses in autumn
As autumn approaches, climbing roses grow vigorously. You can剪 off the weak, very thin, and densely grown branches to promote the growth of new branches, which will become sturdy. There is no need to prune branches that are robust, allowing them to grow freely. Moreover, in the process of cultivating climbing roses, they require at least 6 hours of sunlight every day. Insufficient sunlight can lead to thin stems and leaves.
As autumn arrives, climbing roses grow vigorously. You can剪 off the weak, very thin, and densely grown branches to avoid affecting the ventilation of the plant and the occurrence of diseases and pests. This also effectively promotes the growth of new branches, while robust branches do not need to be pruned and can be left to grow.
In cultivating climbing roses, it is important to choose well-ventilated, slightly acidic soil. The plant has high requirements for sunlight, needing at least 6 hours of sunlight every day. Insufficient sunlight can lead to thin stems and leaves. Additionally, the plant can produce many flowers and has a high demand for fertilizer. Fertilize once during the spring germination and apply additional fertilizer after flowering.
Climbing roses are prone to black spot disease and aphid infestations during growth. Black spot disease can cause leaves to fall, affecting the plant's aesthetics. You can spray Bordeaux mixture weekly for prevention and treatment. Aphids can damage leaves and can be controlled by spraying dimethoate.
Climbing roses thrive in sunlight and warmth, suitable for growing in rich, organic, loose, and fertile slightly acidic soil. The optimal growth temperature for the plant is between 15-26°C. The plant will enter a dormant state when the temperature drops below 5°C in winter and a semi-dormant state when the temperature exceeds 30°C in summer.
