Spacing & depth
How to plant
Push bulblets root-side-down, tip just at soil level. They produce hollow onion greens spring through fall, then form clusters of tiny bulblets on top of the stalk. The top-heavy stalks bend to the ground and 'walk' — bulblets root where they land, giving you a new patch each year.
Grower's tip
Truly perennial — plant once, harvest forever. Use greens like scallions, small underground bulbs like shallots, topsets pickled or replanted. Let a few walk to expand the patch; pull the rest to keep it in bounds.
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.
Prefers top-watering — Top-water at the soil surface — keep the necks and crowns as dry as possible to prevent basal rot.
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
For garlic and onion: dig when the bottom 3 leaves brown and top leaves still stand. Loosen with a fork, don't yank. Cure whole plants 2–3 weeks in a warm, airy, shaded spot.
Post-harvest storage & preservation
After curing, trim tops and roots. Store hardneck garlic 4–6 months, softneck 8+ months in a cool (50–60°F), dry, dark spot with airflow. Never in the fridge.
Culinary, medicinal & other uses
Culinary staple (allium bulbs), cut flowers (tulip, daffodil, lily), forced blooms indoors, or perennial garden color.
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.

From your kitchen — grow egyptian walking onion from what you already have
You don't save seed — you plant the topset bulblets that form on top of the stalks.
- 1In late summer, cut off the top clusters of tiny bulblets once they start to firm up.
- 2Separate individual bulblets — pea-size and up all grow.
- 3Plant point-up, 1 in deep, 6 in apart, in late summer or fall.
- 4First green shoots appear in a few weeks; they overwinter and take off again in spring.
Storage: Truly perennial — plant once and split clumps every 3–4 years.
