Troubleshooting
Clematis viticella problems — and how to fix them
Clematis viticella (Clematis viticella) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Tangled, congested growth
Vigorous stems can knot together if not pruned. Hard prune to 20-30 cm above ground in late winter (Group 3) for a clean, well-spaced framework.
Slow spring start
Like many Group 3 clematis it leafs out late; bare stems in early spring are normal and not a sign of death—wait before assuming loss.
Dry roots in summer
Reduces flowering. Maintain a cool, shaded, mulched root run and water deeply during dry spells.
Aphids and slugs
Aphids on soft new shoots and slugs on emerging spring growth. Inspect early-season shoots and rinse or remove pests by hand.
