Introduction
Forcing bulbs indoors brings spring flowers to your windowsill in the depths of winter. Amaryllis, paperwhites, and hyacinths are the easiest to force.
Choosing the Right Bulbs
Select firm, plump bulbs that feel heavy for their size. Avoid any with soft spots, mold, or visible damage.
Consider bloom time, height, and color when planning your bulb garden. Layer early, mid, and late bloomers for continuous color.
Planting Guide
Plant bulbs at a depth roughly three times their diameter. Pointed end goes up, flat end down.
Chill spring bulbs in the refrigerator for 12-16 weeks before potting to simulate winter conditions.
- Dig individual holes or trench the entire bed for mass plantings
- Space bulbs according to package directions for best visual impact
- Add bone meal to the planting hole for strong root development
- Water well after planting to settle soil and initiate root growth
Care and Maintenance
Water regularly during active growth periods but reduce watering after foliage dies back.
Allow foliage to yellow and die naturally — this feeds the bulb for next year’s bloom.
Pro Tip: Don’t braid or tie dying foliage. Let it flop naturally or interplant with perennials that will hide it.
Seasonal Considerations
Spring bulbs go in the ground in fall, 6-8 weeks before the ground freezes. Summer bulbs are planted in spring after the last frost.
Key Takeaway: The secret to amazing bulb displays is planting generously. A drift of 25 tulips looks far better than a row of 5.
