Growth Stages

1

Establishment

4-6 weeks

New bare-root or container roses are planted; canes are woody with few leaves

Water thoroughly after planting. Prune to 12-18 inches height. Keep soil consistently moist for 4-6 weeks. Mulch to protect roots and retain moisture.

2

Vegetative Growth

4-8 weeks

Plant leafs out rapidly with vigorous cane growth and dark green foliage along stems

Apply balanced fertilizer every 2-3 weeks. Remove any dead or diseased wood. Ensure good air circulation. Continue regular watering.

3

Budding & Flowering

4-6 weeks per bloom cycle

Large hybrid tea buds form at stem tips; blooms open into full, quartered golden-yellow flowers with excellent fragrance

Deadhead spent blooms to encourage reblooming. Apply rose-specific fertilizer or bloom-boosting formula. Protect from pests and diseases.

4

Full Production

4-6 months or longer

Mature established rose produces continuous blooms throughout growing season with thick, healthy canes and dense foliage

Maintain regular fertilizing schedule. Prune to shape in late winter/early spring. Monitor for pests and diseases. Water consistently.

5

Winter Dormancy

2-4 months

Plant slows growth, foliage may drop, and canes become dormant in preparation for winter rest

Stop fertilizing in fall. Prune back in late winter before growth resumes. In cold zones, apply winter mulch around base. Reduce watering.
