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 Tulipa Double Late 'Canyon'
Planting: Plant in fall after soil temperatures fall below 55°F. Set bulbs 6–8 inches deep, pointed end up. Choose a location with some shelter to help support the heavier, fully double blooms that emerge late in the season.
Spacing: Space bulbs 4–6 inches apart. For a bold effect, plant in groups of 10 or more—this amplifies the fullness of their densely petaled flowers.
Light: Full sun ensures the best floral display. They will handle light shade, but expect fewer blooms with less than 6 hours of sun.
Soil: Prefers well-drained, neutral to slightly acidic soils (pH 6–7). Avoid heavy or poorly drained spots to prevent bulb rot—especially important given their longer growth cycle.
Watering: Water after planting to settle the soil. In spring, water during prolonged dry spells, ensuring the soil doesn’t stay soggy as these large blooms are more prone to damage from excess moisture.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) to develop strong roots and initiate flower buds.
Fertilization: Apply a balanced bulb fertilizer at planting and again in spring as shoots appear to support robust stems and large flowers.
Pests: Typically low-maintenance. Mulch or mesh can help deter squirrels. Provide good drainage to avoid rot. Deer will eat the flower buds or emerging foliage, especially in early spring. Protect with fencing or repellents in high-pressure areas.
Disease: To help prevent Botrytis (Tulip Fire), plant only healthy bulbs in sunny, airy locations with good drainage. Avoid overhead watering, and remove any suspect foliage immediately—do not compost. Rotate plantings regularly; if Botrytis has occurred, avoid the site for at least three years.
