How to Grow Snowdrops

How to Grow Snowdrops (and How to Split Them “In the Green”)

There is something so hopeful about snowdrops. Just when the garden feels grey and tired, these brave little white flowers push through the cold ground and quietly announce that spring is on its way.

In this post, I’ll share how to grow snowdrops successfully, and how to split and replant them “in the green” in February — the simplest and most reliable way to multiply your display year after year.

If you’d like to see the full step-by-step demonstration, you can also watch my accompanying video where I show exactly how I do it in my own garden.

Meet the Snowdrop: Galanthus nivalis

The common snowdrop, Galanthus nivalis, is the variety most of us grow in UK gardens. It flowers from January to early March, depending on the weather, and thrives in cool conditions.

Snowdrops are woodland bulbs by nature. In the wild, they grow in dappled shade beneath deciduous trees, flowering before the canopy fills out in spring.

How to Grow Snowdrops Successfully

1. Choose the Right Spot

Snowdrops prefer:

• Partial shade (especially under trees or shrubs)

• Moist but well-drained soil

• Humus-rich ground (leaf mould is perfect)

• A position that isn’t baked dry in summer

They are ideal for:

• Under deciduous trees

• The front of borders

• Naturalised drifts in grass

• Along paths where you can enjoy them up close

2. Planting Snowdrop Bulbs (Dormant)

You can buy dry bulbs in autumn, but they can be very unreliable if they’ve dried out too much before planting.

If planting dormant bulbs:

• Plant in autumn (September–November)

• Set them around 5–8cm deep

• Plant in informal clumps rather than straight lines

• Water well if the soil is dry

However, the most successful way to establish snowdrops is to plant them “in the green.”

What does “In the Green” mean?

“In the green” simply means planting or dividing snowdrops while they still have their leaves attached — just after flowering, usually in February or March.

This is how snowdrops naturally spread in woodland settings, and it dramatically improves your success rate.

Why Split Snowdrops?

Snowdrops multiply underground, forming clumps over time. After a few years, those clumps can become congested, which may reduce flowering.

Splitting them:

• Encourages stronger flowering

• Prevents overcrowding

• Helps you create larger drifts

• Allows you to fill gaps elsewhere in the garden

• Gives you free plants 🌿

February — just after flowering — is the perfect time.

How to Split Snowdrops “In the Green”

Here’s the simple method I use every year:

Step 1: Lift the Clump

Using a hand fork or spade:

• Gently loosen the soil around the clump

• Lift the entire cluster carefully

• Keep as much soil around the roots as possible

Don’t worry — they are tougher than they look.

Step 2: Divide the Clump

You can:

• Gently tease apart small groups by hand

• Or slice larger clumps into sections with a spade

Aim for small groups of 3–10 bulbs per section rather than single bulbs. They establish faster this way.

Step 3: Replant Immediately

This is key.

• Replant straight away

• Keep them at the same depth they were growing

• Firm the soil gently

• Water well

Don’t allow the roots to dry out.

Where to Replant

When replanting divided snowdrops:

• Plant in drifts for a natural look

• Tuck them under trees or hedges

• Dot them through borders

• Fill bare winter patches

Think of how they grow in nature — informal and slightly scattered.

What Results Can You Expect?

By dividing snowdrops in the green:

• You’ll often see little to no setback the following year

• Clumps will establish quickly

• Flowering becomes more generous over time

• Within a few seasons, you can double or triple your display

It’s one of the most satisfying (and economical) garden jobs you can do in late winter.

Ongoing Care for Snowdrops

Once planted:

• Allow the foliage to die back naturally

• Don’t tie leaves in knots (they need to photosynthesise)

• Avoid cutting grass over them too early

• Top dress with compost or leaf mould annually

After flowering, the leaves are feeding the bulb for next year’s display — so patience pays off.

What If You Don’t Have Any Snowdrops Yet?

If you don’t currently have snowdrops in your garden, don’t worry — they are very easy to introduce.

The best way to start is by buying snowdrops “in the green” in late winter (February–March). These are small growing clumps lifted and sold while still in leaf, and they establish far more reliably than dry autumn bulbs.

You can find them at:

• Local garden centres in late winter

• Specialist bulb nurseries

• Open gardens that sell divisions

• Gardening friends (snowdrops are often generously shared!)

Look for healthy plants with:

• Green, upright leaves

• Firm bulbs

• Moist roots (not dried out)

Plant them as soon as possible after purchase. Keep them at the same depth they were growing in the pot or bag, water them in well, and allow the foliage to die back naturally.

Starting Small Is Fine

You don’t need hundreds to begin.

Even one or two small clumps planted in the right place will slowly increase. Within a few years, you’ll have enough to begin dividing and spreading them around your garden.

Where to Plant New Snowdrops

If you’re introducing snowdrops for the first time, choose a spot that mimics their natural woodland setting:

• Under deciduous trees

• Along a hedge line

• In dappled shade

• In moist but well-drained soil

Avoid very dry, sunny borders or waterlogged ground.

A Long-Term Investment

Snowdrops aren’t instant-impact plants — they’re a slow and steady joy. But once established, they will return faithfully every year and gradually naturalise.

And once you have your first clump thriving, you can begin dividing them “in the green” each February — and that’s when the real magic begins 🌿

A Gentle February and March Garden Job

Dividing snowdrops in February feels like a hopeful act — a quiet investment in next year’s spring.

There’s something very special about increasing your snowdrops year after year and watching those white flowers gently spread across the garden.

Frequently asked questions about growing snowdrops

1) Do snowdrops self seed? 

Yes — snowdrops can self-seed, but it’s not their main way of spreading.

Most common snowdrops, including Galanthus nivalis, spread far more reliably by forming underground bulb offsets (which is why dividing them “in the green” works so well).

How snowdrops self-seed

After flowering, snowdrops produce a small seed pod at the base of the fading bloom. When ripe:

• The pod splits open

• Seeds fall to the ground

• Ants often carry them away (they’re attracted to a fatty coating on the seed called an elaiosome)

This natural partnership helps distribute seeds around the garden.

Why you don’t see lots of snowdrop seedlings? 

Although they do self-seed:

• Not all varieties of snowdrops self-seed. In our experience, it depends on the type of flower. As a general rule it depoends on whether insects are able to polinate the snowdrop flowers. The double varities in our garden do not self seed as the pollen is inaccessible. They need to be propagated by division. 

• Germination can be slow

• It may take 3–5 years for a seed-grown plant to flower

• Not all seeds survive or establish

• Some cultivated varieties produce little viable seed

So while self-seeding does happen — especially in woodland-style gardens — it’s a gradual process.

Dividing established clumps in February “in the green” is much faster and more reliable than waiting for seedlings to mature.

Seedlings are a lovely bonus surprise. Division is the dependable method.
