About Pelargonium 'Fair Ellen'

Pelargonium 'Fair Ellen' · also called Fair Ellen pelargonium, Oak-leaved geranium · herb

'Fair Ellen' is a robust oak-leaved scented pelargonium with dark-zoned, deeply lobed leaves and a balsam-pine fragrance. It produces clusters of pink flowers veined deeper rose and forms a tidy, weather-tolerant mound. Like its relatives it favours bright light, free-draining soil, warmth and protection from frost over winter.

Mature size: Around 30-45 cm tall and 30-45 cm wide in a container.

Watch for — Sparse flowering: Too little light or nitrogen-heavy feeding reduces blooms; move to full sun and switch to a high-potash feed.

How to tell pelargonium 'fair ellen' needs repotting

Repotting on a calendar is less reliable than reading the plant. For pelargonium 'fair ellen', 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 'fair ellen' 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 'fair ellen'

Pot on seedlings as they grow; not a perennial repot. Pelargonium 'Fair Ellen'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Bushy, mounding oak-leaved type that is sturdier and more weather-resistant than many scented pelargoniums; pinch tips to maintain density..

What size pot to step pelargonium 'fair ellen' up to

Pot pelargonium 'fair ellen' 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 'fair ellen'

Pot pelargonium 'fair ellen' 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 'fair ellen'

Pot on before it is root-bound. Check pelargonium 'fair ellen' 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 peat-free 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 'fair ellen' 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 'fair ellen'

Pelargonium 'Fair Ellen' wants free-draining loam-based or peat-free compost with added grit. Lighten the mix with perlite or grit for fast drainage. Always use a pot with drainage holes; soggy compost causes base rot. 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 'fair ellen' — frequently asked questions

How often should you repot pelargonium 'fair ellen'?

Pot on seedlings as they grow; not a perennial repot for pelargonium 'fair ellen'. Pelargonium 'Fair Ellen' 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 peat-free 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 'fair ellen' need?

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

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

No. Even a fast-growing pelargonium 'fair ellen' 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 'fair ellen' after repotting?

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