Amaryllis Bulb Growing Guide: Containers, Gardens, and Year-Round Care

Amaryllis (Amaryllis belladonna) produces magnificent 10+ cm bell-shaped flowers on 50-60 cm stems with strap-like leaves. Properly maintained bulbs can flower for 75 years, making them exceptional garden investments.

Container Culture

Plant in October (or post-dormancy) in 5-inch pots with equal parts loam, sand, organic matter (pH 6.0-6.8). Add ½ inch gravel for drainage. Cover half the bulb with soil. Select premium bulbs without emergent leaves.

Garden Planting

Late September in elevated beds enriched with compost. Any well-drained soil works. Space bulbs 12 inches apart, cover halfway. Mulch to conserve moisture and suppress weeds.

Bloom and Post-Bloom Care

• During flowering: Maximum sun, ample water. At 6-inch stalk height, apply low-nitrogen fertilizer for larger, brighter blooms. Remove faded flowers to prevent seed formation.
• After blooming: Continue water/fertilizer for leaf/bulb growth. Large bulbs produce 3 stalks.
• Summer: Semi-shade, regular water.
• Dormancy (September): Leaves dry completely. Stop watering. Store bulbs cool/dry until regrowth signs appear. Repot or leave in place.

With this cycle, amaryllis delivers reliable, spectacular displays year after year.
