Clematis 'Nelly Moser' problems — and how to fix them
Clematis 'Nelly Moser' (Clematis 'Nelly Moser') 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.
Clematis wilt
Large-flowered clematis can suddenly collapse from a fungal wilt. Plant deep (bury the crown 5-8 cm below soil level) so it can regrow, cut out affected stems to healthy tissue, and keep plants well watered and fed.
Faded flower colour
The carmine bar bleaches to near-white in strong sun. Site in part shade, ideally with morning sun, to preserve the rich two-tone effect.
Bare base, all flowers up high
Group 2 clematis tend to go leggy. A harder reduction of some stems in spring and training shoots low and outward helps clothe the base.
Dry, stressed roots
Hot, dry soil causes poor growth and few flowers. Mulch deeply, shade the root zone, and water regularly through summer.
