Troubleshooting
New Dawn Rose problems — and how to fix them
New Dawn Rose (Rosa 'New Dawn') 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.
Sparse flowering on old wood
Left unpruned, it builds bare leggy bases with bloom only at the top. Tie canes horizontally and prune side shoots back in late winter to spread flowering down the plant.
Dry feet against a wall
Planted in the rain shadow at a wall base, roots stay parched and flowering suffers. Plant 30-45 cm out from the wall and water and mulch generously during establishment.
Aphids
Greenfly cluster on soft tips and buds in spring. Hose off, squash, or let predators control them; tall growth can make spraying impractical anyway.
Blackspot in wet years
Though notably disease-resistant, it can still spot in prolonged wet weather. Clear fallen leaves, prune for airflow, and avoid overhead watering.
