Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Growing and Maintenance Tips for Tulipa Single Late 'Sky High Scarlet'

Planting: Plant in fall when soil temperatures drop below 55°F. Set bulbs 6–8 inches deep with the pointed end up. Choose a sunny, sheltered site to protect their tall stems and graceful blooms from wind.
Spacing: Space bulbs 4–6 inches apart. For a dramatic effect, plant in groups of 10 or more—ideal for borders, cutting gardens, or formal displays.
Light: Full sun encourages strong stems and rich color. While light shade is tolerated, consistent sun enhances bloom longevity and form.
Soil: Use well-drained, neutral to slightly acidic soil (pH 6–7). Avoid poorly drained areas—French tulips are sensitive to bulb rot in wet spring conditions.
Watering: Water after planting to settle the soil. In spring, water only during prolonged dry spells to maintain bloom integrity without over-saturating the roots.
Temperature & Dormancy: Requires 12–16 weeks of cold (below 50°F) for root development and bud initiation.
Fertilization: Apply a balanced bulb fertilizer when planting and again in early spring as shoots emerge to support stem strength and bloom quality.
Pests: Squirrels may disturb bulbs—use mesh or mulch to deter them. Deer will eat buds and foliage, especially early in spring, so use fencing or repellents in high-pressure areas.
Disease: To prevent Botrytis (Tulip Fire), plant only healthy, firm bulbs in sunny, well-ventilated areas. Avoid overhead watering and remove any infected material—never compost. Rotate planting zones annually and avoid replanting in affected sites for at least three years.
