How to plant
Plant firm, unblemished bulbs in fall, pointy end up. In zones 9–10, pre-chill bulbs in the fridge 12–16 weeks first. Water once at planting, then leave alone until spring. Allow foliage to yellow before cutting for next year's flower.
Grower's tip
Treat as annuals in mild climates — most modern hybrids only bloom well the first spring. Species tulips naturalize better. Deer love the buds; try daffodils nearby as a deterrent.
Soil preferences
Loose, well-drained soil — bulbs rot in wet feet.
6.0–7.0
Compost + bone meal or rock phosphate worked into the planting hole.
Watering
Water in at planting, then only during active growth. Let bulbs go dry during dormancy.
Deep watering at the base. Avoid overhead watering after leaves die back.
Overwatered: soft, mushy bulbs at harvest; basal plate rot. Underwatered: small bulbs, thin necks.
Either works — Top-water in-ground bulbs (garlic, onion, shallot, tulip, daffodil) at the soil surface — keep the crown mostly dry. Bottom-water forced bulbs and potted amaryllis. Stop watering entirely once foliage yellows and dies back.
Temperature tolerance
60–75°F (15–24°C) during growth
40–60°F (4–15°C)
Hardneck garlic, shallots, and daffodils need a cold winter to bulb properly. Tender bulbs (dahlia, gladiolus) must be lifted in cold zones.
Container growing
Yes — great in containers
8+ in deep, wide enough to space bulbs 2–3× their diameter
Deep pot for tulips and daffodils; shallow bowls for crocus.
Detailed harvesting
Nothing here is harvested for the kitchen. Wear gloves for any cutting or deadheading, keep the sap off your skin and eyes, and wash your hands and tools afterwards.
Post-harvest storage & preservation
Do not dry, store or preserve any part of this plant near food. Bag prunings for the bin — never compost them where animals browse, and never burn them.
Culinary, medicinal & other uses
Ornamental only — this plant is poisonous and has no food, tea or home-remedy use. Grow it for looks, wear gloves, and keep it away from children, pets and livestock.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Propagate by offset bulblets, not seed — bulbs mature much faster from a clove/bulb than from seed.
Not applicable when replanting clones. Cross-pollinated seed rarely comes true.
Save the biggest, firmest bulbs each year and replant. Over generations you build a locally-adapted strain.
