Bulb Gardening Guide: Planting, Naturalizing, and Container Growing for Year-Round Blooms

Bulb Types

True bulbs (tulips, hyacinths, daffodils), corms (crocus, gladiolus), rhizomes (iris, canna), tubers (dahlia, begonia), tuberous roots (amaryllis). All store food for dormant periods.

General Requirements

• Moist, rich, well-drained soil.
• Sunny position (most).
• Planting depth: 2–3 times bulb height.

Regional Timing

• Temperate zones: Chill tulips 4–8 weeks in fridge; plant at coldest time.
• Cold areas: Plant late autumn.
• Daffodils naturalize in lawns; delay mowing 6 weeks post-bloom.
• Woodland bulbs (bluebells, snowdrops): dappled shade under deciduous trees.

Container Growing

• Minimum 4" soil below bulb, 2–4" above.
• Bury pot in garden to protect from hoeing/rodents.
• Wire cages deter rodents.
