Growing Larger Daffodils: Planting, Feeding, and Division

Secrets to Big, Bold Daffodil Blooms

A gardener asks how to make daffodils larger – what to add to planting holes.

Planting Time & Conditions

• When: Late summer/early fall (soil ≤60°F).
• Root establishment: Fall/winter – critical for spring bloom size.
• Soil: Well-drained, sandy-loam, pH 6.5–7.0. Test first.
• Depth: 6" (3× bulb height).
• Spacing: Clumps of 3–6 bulbs, 4–6" apart.

Planting Hole Amendments

1. Dig area deeper than planting depth.
2. Add 2–3" layer well-rotted manure or compost – easy root growth, nutrients.
3. Plant bulbs, add 1 tsp bone meal per bulb mixed into covering soil – boosts K for bulb development.

Ongoing Care

• Annual feed: Early spring, 5-10-5 organic fertilizer worked into top 2–3".
• Mulch: 2–3" bark, chips, or compost – stable temps, moisture retention.
• Foliage: Leave until yellow (6 wks post-bloom) – feeds bulb.
• Division: Every 3–5 years in fall – separate crowded clumps, replant largest bulbs.

Site Selection for Longer Bloom

Afternoon shade extends flowering – avoids heat stress.

Bottom Line

Plant in fall at 6" depth in clumps with compost + bone meal. Feed annually, mulch, don't cut foliage early, divide periodically. Afternoon shade = longer blooms.
