Growth Stages

1

Establishment

First 4-6 weeks after planting

New canes develop with wrinkled rugose foliage; plant focuses on root development

Water regularly to establish roots. Mulch around base. Avoid heavy pruning first year.

2

Vegetative Growth

4-8 weeks in spring

Vigorous upright growth with dense, wrinkled dark green foliage appearing along canes

Apply balanced fertilizer monthly during growing season. Deadhead spent blooms to encourage more flowering. Remove any dead or diseased wood.

3

Blooming

Late spring through fall (repeating bloom cycles)

Abundant semi-double crimson-purple flowers appear in clusters along canes with intense fragrance

Deadhead regularly to promote continuous blooming through summer. Ensure consistent moisture. Apply rose fertilizer formulated for blooming.

4

Hip Development

Late summer through winter

After flowers fade (especially in late summer/fall), large decorative orange-red hips form

Leave some spent flowers to develop hips. Stop deadheading in late summer to allow hip formation. Hips provide fall interest and wildlife food.

5

Dormancy

November through February

Foliage drops and canes harden off for winter; plant enters rest period

Reduce watering. Do not fertilize. Apply winter mulch in zones 3-5 if needed. Prune lightly in early spring (late March to early April).

Harvest Tips
