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

Roots emerging from the drainage holes (slow on this plant, so this is a strong signal).
The plant has become top-heavy and tips its pot over.
Genuinely stalled growth across a full season despite adequate light — not just the naturally slow pace this plant always has.

What size pot to step pelargonium graveolens 'lady plymouth' up to

Step up just one pot size, and only when the roots are genuinely packed. Because pelargonium graveolens 'lady plymouth' grows so slowly, a big pot of damp soil will simply sit wet for months around a small root system and invite rot.

The best time of year to repot pelargonium graveolens 'lady plymouth'

Early spring, just as new growth restarts, is the ideal window for pelargonium graveolens 'lady plymouth'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting pelargonium graveolens 'lady plymouth'

Time it for spring. Repot pelargonium graveolens 'lady plymouth' in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip pelargonium graveolens 'lady plymouth' out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh free-draining loam or potting mix with added grit or perlite in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water pelargonium graveolens 'lady plymouth' again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for pelargonium graveolens 'lady plymouth'

Pelargonium graveolens 'Lady Plymouth' wants free-draining loam or potting mix with added grit or perlite. A peat-free multipurpose compost opened up with grit or perlite. Excellent drainage is non-negotiable; it prefers neutral to slightly alkaline conditions. 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 graveolens 'lady plymouth' — frequently asked questions

How often should you repot pelargonium graveolens 'lady plymouth'?

Every 2–4 years — it is in no hurry for pelargonium graveolens 'lady plymouth'. Repot pelargonium graveolens 'lady plymouth' only every 2–4 years — it builds roots slowly and a yearly repot is wasted effort. Move up just one pot size in spring with fresh free-draining loam or potting mix with added grit or perlite. The main error is repotting too often and into too large a pot, which leaves cold wet soil around the roots.

What size pot does pelargonium graveolens 'lady plymouth' need?

When is the best time of year to repot pelargonium graveolens 'lady plymouth'?

Can you put pelargonium graveolens 'lady plymouth' straight into a much bigger pot?

No. Even a fast-growing pelargonium graveolens 'lady plymouth' 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 graveolens 'lady plymouth' after repotting?

Not immediately. Wait about 4 weeks after repotting pelargonium graveolens 'lady plymouth'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
