Growth Stages

1

Establishment

4-6 weeks

Newly planted rose is establishing roots; limited growth above ground with sparse foliage

Water regularly to keep soil moist but not waterlogged. Apply 2-3 inches of mulch around base, keeping it 3 inches away from canes. Avoid fertilizing for first month.

2

Vegetative Growth

8-12 weeks

Plant develops strong canes and bushy foliage; leaves emerge as reddish new growth maturing to deep green

Begin light fertilizing with balanced rose fertilizer every 4-6 weeks. Remove any dead or crossing canes. Monitor for pests and diseases. Maintain consistent moisture.

3

Flowering

6-8 weeks per flush, repeats throughout season

Flower buds form at branch tips; blooms open into deeply cupped, quartered crimson flowers with strong fragrance

Deadhead spent blooms to encourage continuous flowering. Increase fertilizer frequency to every 3-4 weeks with phosphorus-rich formula. Maintain steady watering. Enjoy the fragrance!

4

Repeat Blooming

Ongoing from early summer through fall frost

Plant enters multiple bloom cycles throughout growing season, with brief rest periods between flushes

Continue regular deadheading, watering, and feeding. Watch for mid-season pests. Reduce watering slightly if temperatures cool between flushes. Mulch well in summer.

5

Winter Dormancy

3-4 months

Plant slows growth; foliage yellows and drops; rose enters dormant phase

Stop fertilizing 6 weeks before first frost. Reduce watering but keep soil from completely drying. In zones 5-6, mound soil 10-12 inches over base for protection. Remove fallen leaves. Prune in early spring.

Harvest Tips
