How to Treat Clematis Leaf Wilt
Clematis leaf wilt, also known as Clematis leaf and stem spot, is a fungal infection that affects the Clematis vining plant. The infection attacks the plant low in the stem, preventing the plant from transmitting water and nutrients through the vine. The vine and leaves droop, brown and eventually fall off. Even after leaf wilt has destroyed all visible parts of a Clematis plant, treatment may still save the roots, allowing the vine to recover and bloom again in the next growing season.
things you’ll need:
- Pruning shears
- Clean cloth
- Rubbing alcohol
- Trash bag
- Systematic fungicide
- Remove affected leaves or stems with pruning shears. Between cuts, dampen a clean cloth with rubbing alcohol and wipe down the blades so you do not spread the infection to healthy parts of the plant. Cut affected vines all the way back to the ground if necessary.
- Pick up fallen leaves—along with the portions pruned from the vine—place them in a plastic bag and discard it with your trash.
- Water the soil around the Clematis vine deeply, so the soil is moist to the touch at least 2 inches below the soil surface.
- Apply a systematic fungicide to the soil around the plant and to the base of the plant that remains, according to the package directions.
- Repeat the application of the fungicide in spring, before the plant produces new shoots. Apply the fungicide monthly in summer, and then one final time in fall after the leaves drop.
