If the previously lush green leaves on a clematis gradually turn yellow, this damage indicates a deficiency. If the leaf veins are still clearly visible, there is an urgent need for action. Find out here what to do now.
Yellowing of the leaves indicates a lack of nutrients
In order for a majestic clematis to develop its massive biomass, it needs a balanced supply of nutrients. If there are deficiencies here, she first reacts with yellow leaves. These will eventually turn brown and fall off. Therefore, pay attention to this care:
- Fertilize clematis in the garden every 6-8 weeks with a potassium-rich preparation
- Fertilize clematis in tubs every 4 weeks from March to September with 20 grams of special fertilizer
- Alternatively, fertilize the plant organically every 1-2 weeks with compost, horn shavings (€32.93) and comfrey manure
- If the pH is below 5, add algae or vital lime
However, if brown spots with a yellow forecourt appear on the leaves, the dreaded clematis wilt has struck. Immediately remove any infected leaves and treat the clematis with a fungus-free fungicide.
