Establishment
4-8 weeksNewly planted rose sends out basal breaks and initial root system development. Canes are tender and foliage may be sparse.
Water consistently, provide protection from harsh winds, avoid heavy pruning. Apply mulch around base. Monitor for transplant shock.
Vegetative Growth
6-12 weeksVigorous cane development with climbing/pillar growth habit. Foliage becomes fuller and more robust, reaching 6-8+ feet tall depending on training.
Train canes horizontally or fan them for more blooms. Remove weak or crossing canes. Begin light feeding with rose fertilizer.
First Flowering
4-6 weeksLarge, quartered double blooms appear in apricot-orange with salmon and yellow tones. Flowers are highly fragrant and up to 4-5 inches across.
Deadhead spent flowers to encourage repeat blooming. Provide support structure if needed. Continue regular watering and feeding.
Summer to Fall Blooming
8-16 weeksSuccessive flushes of flowers throughout the growing season, with cooler autumn temps intensifying color depth. Plant reaches mature size and character.
Maintain consistent watering and fertilizing schedule. Watch for pests and diseases. Prune out any dead wood promptly.
Dormancy & Winter Preparation
8-12 weeksGrowth slows in fall as temperatures drop. Foliage may decline; canes harden off. Plant prepares for winter rest.
Reduce fertilizing in late summer. Stop deadheading in fall to allow hips to form, signaling dormancy. Apply winter mulch in zone 6-7. Prune in early spring.

Harvest Tips
Cut blooms in early morning when petals are fully hydrated but before the heat of the day. Use sharp pruning shears and cut at a 45-degree angle above an outward-facing leaf node. Remove lower foliage from stems before arranging. Blooms last 7-14 days in a vase with fresh water changed every 2-3 days. For longest cane life and branching, deadhead faded flowers by cutting just above the first 5-leaflet leaf.
