Planting & seasonal timing
Northern Hemisphere planting months: not yet verified in our database.
Northern Hemisphere pruning months: February, March.
For the Southern Hemisphere, these seasonal windows shift approximately six months. Check your local frost forecast, soil temperature, and species requirements; calendar months are not a guarantee of planting safety.
No deadheading needed — old blooms drop cleanly. Prune hard in late winter (cut to 12 inches) for best performance. Extremely disease resistant. Feed generously for maximum rebloom cycle.
Pruning
Cut back hard to 12–18 inches in late winter. Lightly shape after each flush of bloom if desired.
Fertilizer
Rose fertilizer or balanced slow-release
Early spring and monthly through summer
Mulch
3–4 inches organic mulch.
