Plant snowdrops as dry bulbs in fall after the soil cools, or move clumps in the green just after flowering. Pointed tip up, about 3 inches deep and 3 inches apart.
When to plant — dry bulbs or in the green
| Factor | Recommended | Avoid |
|---|---|---|
| Dry bulbs | Fall, once night temperatures sit near 40–50°F; plant the week they arrive | Shrivelled, light, papery bulbs left on a shelf |
| In the green | Just after bloom, leaves still green, roots intact | Letting lifted plants dry out before they go back in |
| Depth | About 3 inches deep, 3 inches apart, pointed tip up | A shallow set that heaves in frost |
| Site | Winter sun, summer dappled shade, moist draining soil | A bed you will till or mow in April |
Plant dry bulbs in fall after the soil cools. Move established clumps in the green — after flowering, while the foliage is still green. [1]
When should you plant snowdrop bulbs?
Dry bulbs in fall after the soil cools. Established clumps just after bloom, while the leaves are still green.
Can you plant snowdrops in the green?
Yes. Lift after flowering with leaves attached, keep the roots moist, and replant at once at the old soil line.
How to plant snowdrops
- Choose a spot with winter sun under a deciduous tree or at the front of a border you will not mow in April.
- Work leaf mold or compost into loose soil that drains.
- Set dry bulbs about 3 inches deep and 3 inches apart, pointed tip up. [2]
- For plants in the green, separate the bundle and set each bulb at the old soil line — the white stem underground.
- Firm gently and water in once. Mark the patch before summer rest hides it.
Pointed tip up, flat end down. [3] In the US, dry fall bulbs are the usual shop stock. Plant them the week they arrive so they do not dry out. In-the-green bundles are uncommon in US catalogs; a neighbour's extra clump after bloom is the usual source. [4]
greater snowdrop can take a little more space than common snowdrop. G. reginae-olgae runs on a fall-bloom calendar: dry bulbs in late summer, not the generic spring-snowdrop week.
How deep do I plant snowdrop bulbs?
About 3 inches deep and 3 inches apart, pointed tip up. In-the-green plants go at the same depth they were growing.
What fails at planting
- Shrivelled dry bulbs — reject them, or expect a weak first year.
- Planting too shallow — frost heave and exposed bulbs.
- Digging the patch in July to “check” — leave it unmarked and you will spear dormant bulbs.
- Mowing a lawn planting while leaves are still green.

FAQ
Should I fertilize at planting?
No. Water in thoroughly. Save a light bulb fertilizer for when shoots appear, or after bloom, on an established clump.
What if nothing shows the first spring?
Common with dry-bulb plantings. Wait a second season before you assume failure. Do not dig to inspect.
Can I start rare clones in a pot?
A shallow pan is fine as a holding step. Move the plant into the ground in the green after its first bloom.
