Troubleshooting
Clematis recta problems — and how to fix them
Clematis recta (Clematis recta) 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.
Flopping stems
The lax, non-clinging stems collapse without support. Insert grow-through ring stakes or twiggy supports early in spring before the clump bulks up.
Powdery mildew
Dense leafy growth can develop mildew in dry, crowded conditions late in the season. Improve airflow, avoid drought stress, and cut back after flowering if needed.
Drying out
Dislikes dry soil and may wilt or flower poorly. Keep the root zone moist with mulch and regular deep watering.
Aphids
Soft new growth attracts aphids in spring. Rinse off or treat early to prevent distorted shoots.
