About Pelargonium 'Snowflake'

Pelargonium 'Snowflake' · also called Snowflake scented geranium, Peppermint snowflake pelargonium · herb

'Snowflake' is a peppermint-scented pelargonium with soft, velvety green leaves splashed cream-white, releasing a cool mint fragrance when brushed. A vigorous, sprawling tender perennial grown for foliage rather than its small mauve-pink flowers, it thrives in bright light, free-draining soil and dislikes wet roots or winter cold below freezing.

Mature size: Around 30-45 cm tall and 30-45 cm wide in a pot; larger if planted out for a season.

Watch for — Leggy, washed-out growth: Too little light stretches the stems and dulls the cream variegation; move to a brighter spot and pinch back to rebuild density.

How to tell pelargonium 'snowflake' needs repotting

Repotting on a calendar is less reliable than reading the plant. For pelargonium 'snowflake', watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot pelargonium 'snowflake' on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot pelargonium 'snowflake'

Pot on seedlings as they grow; not a perennial repot. Pelargonium 'Snowflake'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Vigorous, spreading and somewhat lax scented-leaf type, sending out trailing-to-mounding soft stems; pinch tips regularly to keep it bushy..

What size pot to step pelargonium 'snowflake' up to

Pot pelargonium 'snowflake' on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot pelargonium 'snowflake'

Pot pelargonium 'snowflake' on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting pelargonium 'snowflake'

Pot on before it is root-bound. Check pelargonium 'snowflake' regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh free-draining loam-based or multipurpose compost with added grit at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water pelargonium 'snowflake' in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for pelargonium 'snowflake'

Pelargonium 'Snowflake' wants free-draining loam-based or multipurpose compost with added grit. Use a peat-free mix lightened with perlite or horticultural grit (about one part in four). Always pot into a container with drainage holes — standing water rots the fleshy stems. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting pelargonium 'snowflake' — frequently asked questions

How often should you repot pelargonium 'snowflake'?

Pot on seedlings as they grow; not a perennial repot for pelargonium 'snowflake'. Pelargonium 'Snowflake' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into free-draining loam-based or multipurpose compost with added grit so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does pelargonium 'snowflake' need?

When is the best time of year to repot pelargonium 'snowflake'?

Can you put pelargonium 'snowflake' straight into a much bigger pot?

No. Even a fast-growing pelargonium 'snowflake' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise pelargonium 'snowflake' after repotting?

Not immediately. Wait about 1 week after repotting pelargonium 'snowflake'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
