Choose a location that gets full or part sun. You may plant most bulbs from September to December. 2. For best effect, plant bulbs in clusters. Don't plant in rows ... they will never bloom perfectly straight. It is better to use staggered or random spacing. Try just tossing them in the bed and planting them where they fall. 3. It is best to dig the entire bed area to the proper depth before planting the bulbs. 4. Work in Cotton Boll Compost and gypsum to condition the soil. Good drainage is essential. 5. Mix Hi-Yield Bone Meal into bottom of hole to provide a slow-release fertilizer. 6. Plant bulbs with the pointed end up. 7. Cover bulbs with soil. Use Dutch Bulb Food fertilizer on the surface. 8. Water in with ferti-lome Root Simulator. If the weather is dry, water bulbs once a month through winter as long as the ground is not frozen. 9. Mulch to keep soil moisture in and ground temperatures even. 10. Plant bulbs using our Dutch Bulb Planting Package.
