Wilting in Clematis
Clematis are versatile climbing plants producing flowers in an enormous range of colours and sizes from spring through autumn depending on variety
Clematis care requirements
These care conditions are most relevant to wilting in Clematis. Check each one as a potential cause.
Symptoms to look for in Clematis
Sudden collapse and blackening of one or more stems, often starting at a leaf node, while the rest of the plant may still look healthy.
Common causes in Clematis
Sudden, severe wilting affecting individual stems rather than the whole plant evenly is the classic sign of clematis wilt, a specific fungal disease of this plant, rather than simple drought stress.
How to diagnose wilting in Clematis
Check soil: bone dry = underwatering. Wet + mushy roots = overwatering/root rot. Check temperature and pot size.
How to treat wilting in Clematis
Cut affected stems back to healthy tissue, ideally to ground level, and destroy the removed material. The plant will often regrow from the roots if planted at the correct depth.
Preventing wilting in Clematis
Plant Clematis 5–8cm deeper than the nursery pot so it can regrow from below soil level if wilt strikes, and avoid damaging stems near the base when weeding.
