Growth Stages

1

Establishment

3-4 weeks

New canes emerge with small leaves; plant focuses on root development

Keep soil consistently moist but not waterlogged. Apply mulch to conserve moisture. Pinch off early flower buds to encourage stronger growth.

2

Vegetative Growth

4-8 weeks

Strong canes develop with healthy foliage; multiple shoots emerge from base

Provide balanced fertilizer every 4-6 weeks. Remove any diseased or weak growth. Ensure good air circulation.

3

Budding

2-3 weeks

Flower buds form at stem tips; buds swell and develop color

Fertilize with bloom-promoting formula (higher phosphorus). Maintain consistent watering. Remove lower foliage to improve air flow.

4

Flowering

7-14 days per bloom; continuous with proper care

Large, full red flowers open; petals unfurl in classic hybrid tea form

Deadhead spent blooms above the first 5-leaflet leaf to encourage reblooming. Continue fertilizing every 4 weeks. Monitor for pests and diseases.

5

Dormancy (Winter)

3-4 months depending on climate

Growth slows or stops; plant may lose foliage in cold climates

Reduce watering and fertilizing. Apply winter mulch in zones 5-6. Prune in early spring before new growth emerges.
