Influence of different bulb size and planting time on growth, morphology, and flower quality of Narcissus tazetta under greenhouse conditions.
PubMed · 2026-05-22
Researchers found that daffodil bulb size and planting date both matter for getting quality flowers in a greenhouse. Larger bulbs (12 cm+ circumference) are needed for commercial cut flower production, while planting in late September or mid-October produces better blooms than planting earlier.
1
Bulbs with a circumference of 10 cm or less produced no flowers at any planting date, only vegetative growth.
2
Bulbs 12–14 cm and larger were suitable for commercial cut flower production, while 10–12 cm bulbs were only useful for growing new bulbs.
3
Planting on September 30 or October 15 (vs. September 15) improved flower quality and extended the overall harvest period.
