Frau Dagmar Hartopp Rose (Rosa 'Frau Dagmar Hartopp') 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.
Self-sown seedlings
Generous hips can drop seed and produce volunteers nearby. Deadhead or collect hips if you wish to prevent self-seeding around the plant.
Lime chlorosis
Yellow leaves with green veins indicate alkaline stress. Use neutral-to-acid, free-draining soil, avoid lime, and mulch with acidic organic matter.
Light suckering
On its own roots it suckers modestly. Remove stray suckers to maintain its compact shape or allow them for a low informal hedge.
Spring aphids
Soft new growth attracts aphids. Natural predators usually manage them on this robust shrub; hose off heavier infestations with water.
