Dormancy/Early Spring
4-6 weeksPlant appears bare or with minimal growth; woody canes visible. In late winter/early spring, buds begin to swell along canes.
Prune to remove dead wood and shape plant; apply dormant oil spray if needed. Do not fertilize yet.
Vegetative Growth
4-6 weeksNew leaves emerge along canes, initially reddish or bronze-tinted, turning glossy green. Plant grows vigorously with increasing stem length and branching.
Begin regular watering and feeding with balanced rose fertilizer every 2-3 weeks. Remove any dead canes. Monitor for early pests.
Flowering (First Flush)
6-8 weeksSmall, bright red flowers appear in dense clusters at branch tips. Buds develop continuously as earlier flowers fade. Plant is heavily covered with blooms.
Deadhead spent flowers to encourage continuous blooming. Maintain consistent watering and fertilizing schedule. Apply fungicide preventatively in humid conditions.
Mid-Season Repeat Flowering
8-12 weeks (multiple cycles)Brief reduction in flowering followed by second and subsequent flushes of blooms. Plant may appear slightly less dense between flushes.
Reduce nitrogen fertilizer in late summer to avoid tender new growth. Continue deadheading. Maintain water schedule.
Fall/Dormancy
6-8 weeksFlowering slows as days shorten and temperatures cool. Foliage may show fall colors. Plant prepares for winter rest.
Cease fertilizing 6 weeks before first frost. Reduce watering gradually. Leave some hips (fruit) if desired for winter interest; remove weak canes. Apply winter protection in cold zones.

Harvest Tips
Blitz Rose is an ornamental flower; harvest blooms for cut flowers in early morning after dew dries, cutting stems at 45-degree angle just above a 5-leaflet leaf. Use sharp pruners to remove flower clusters at any time for deadheading and shaping. Stems last 5-7 days in water with flower food.
