I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Growing and Maintenance Tips for Narcissi Long-lasting 'Rotterdam Mixture'

Planting: Plant bulbs in fall, 6 inches deep and 4 to 6 inches apart, with the pointed end up. For a natural look, scatter and plant where they land.
Location: Full sun to partial shade. Mixed daffodils thrive under deciduous trees or in open beds.
Soil: Well-drained, moderately fertile soil with a pH of 6.0–7.0. Enrich with compost or leaf mold.
Watering: Water after planting and during active spring growth. Once foliage yellows, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 3–9. Requires a winter chill to bloom reliably.
Fertilization: Apply compost or a low-nitrogen fertilizer in fall and again in early spring.
Pruning: Allow foliage to die back naturally to recharge the bulb. Remove spent flower stalks for tidiness.
Propagation: Naturalizes by offsets. Divide clumps every 4 to 5 years in summer when dormant.
Pest & Disease: Deer- and rodent-resistant. Good drainage prevents bulb rot.
