Common Name Deutzia
Genus  Deutzia
Species Various hybrids; e.g., D. gracilis, D. scabra
Family Hydrangeaceae
Life Cycle  Hardy Deciduous Shrub
Format 4″ pots
Plug Care Plant young shrubs promptly upon arrival. Plants should be dormant and can withstand cold temperatures - if the plants have broken dormancy and below freezing temperatures are forecasted, protect tender new growth. Keep soil evenly moist but well-drained until established; water regularly while new roots are developing and during periods with no rain. 
Netting / Staking Not required; stems are generally strong and upright with a natural arch/cascade. 
Hardiness Most cultivars are hardy from USDA Zones 5 to 8 (varies by cultivar). Prefers moderate growing temperatures during active growth - generally dislikes extremes. 
Spacing Space plants 3 to 5 feet apart depending on mature habit; for cut-flower production allow room for air circulation to avoid foliar fungus/disease issues. 
Soil Preference Prefers fertile, moist, well-drained soils; tolerates a range of soils and becomes drought-tolerant once established.
Sun Requirement Best flowering occurs in full sun to part shade (full sun produces the absolute best bloom display). 
Pruning Heavy pruning is not necessary; light shaping after first flush can tidy plants but remember Deutzia blooms on last year’s wood so avoid heavy pruning late in the season.
When to Plant Plant in spring swiftly upon arrival. If the plant is still dormant it can withstand below freezing temperatures. If it has broken dormancy, tender new growth needs protection from frost cloth. 
Harvesting Harvest in spring when flower clusters are well developed but before all florets are fully open - many deutzias give best vase performance when cut as buds/opening clusters. Cut stems early in the morning when plant are fully hydrated.
Post Harvest Care Re-cut stems that have been out of water for any period of time and immediately place into cool, clean water (with a floral preservative for best results) - be sure to remove all foliage that will sit below the waterline. Keep harvested stems cool (ideally 35–45°F) until arranging; recut stems and refresh water every 2–3 days to extend vase life.
Diseases / Insects Generally low-maintenance; watch for scale or aphids and treat as needed. Good air circulation helps prevent foliar issues.
Bailey's Notes

Deutzia ‘Raspberry Sunday’

Deutzia are traditionally large, rambunctious, wild looking shrubs that require more maintenance than you might be prepared to give them. This newer cultivar is touted as a ‘dwarf’ variety, but don’t let that label fool you into thinking it’s too small for cutting – this shrub will max out at approximately 3’ by 3’, making it perfectly suitable for cut stems. The beautiful soft pink flowers will appear from mid spring into early summer, and the gracefully arching branches will be absolutely loaded in them. By cutting the stems for floral work, you are also pruning back the plant – after the flowering period is over the shrub will send out lots of new growth which will be your flowering stems for next season. This is a very tidy shrub which not only looks great in the vase but also in the field or garden. This variety should be hardy in USDA zones 5-9 (some sources report zones 6-9, so those in zones 5 and colder should be aware that they might experience some winter kill).
