About Pelargonium odoratissimum

Pelargonium odoratissimum · also called Apple geranium, Apple-scented pelargonium · herb

Pelargonium odoratissimum is a low, sprawling scented pelargonium prized for soft, velvety apple-scented leaves released when brushed. A tender South African perennial, it forms a spreading mound with small white flowers and is grown for fragrance, potpourri and herbal flavouring rather than showy bloom. It thrives in bright light and gritty, free-draining compost.

Mature size: Around 30-45 cm tall and 45-60 cm wide; trailing stems can spread further if unpruned.

Watch for — Stem and root rot: Overwatering or dense compost rots the soft, fleshy stems from the base. Use gritty mix, water only when the surface is dry, and never leave it standing in water.

How to tell pelargonium odoratissimum needs repotting

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

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot pelargonium odoratissimum

Every 2–3 years, into bone-dry mix. Pelargonium odoratissimum's growth habit — low, spreading and mound-forming with trailing stems and soft, rounded, velvety leaves; tends to sprawl rather than climb. — sets the pace. Pelargonium odoratissimum is a low, sprawling scented pelargonium prized for soft, velvety apple-scented leaves released when brushed. A tender South African perennial, it forms a spreading mound with small white flowers and is grown for fragrance, potpourri and herbal flavouring rather than showy bloom. It thrives in bright light and gritty, free-draining compost.

What size pot to step pelargonium odoratissimum up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Pelargonium odoratissimum stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot pelargonium odoratissimum

Spring or summer, while pelargonium odoratissimum is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting pelargonium odoratissimum

Repot dry. Do not water pelargonium odoratissimum for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining, gritty compost ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set pelargonium odoratissimum at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep pelargonium odoratissimum completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for pelargonium odoratissimum

Pelargonium odoratissimum wants free-draining, gritty compost. Use a multipurpose or loam-based compost cut with 25-30% horticultural grit or perlite. Sharp drainage is essential; heavy, water-retentive mixes cause root and stem 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 odoratissimum — frequently asked questions

How often should you repot pelargonium odoratissimum?

Every 2–3 years, into bone-dry mix for pelargonium odoratissimum. Repot pelargonium odoratissimum every 2–3 years into a snug pot of free-draining, gritty compost, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does pelargonium odoratissimum need?

When is the best time of year to repot pelargonium odoratissimum?

Should you water pelargonium odoratissimum after repotting?

No — not straight away. Repot pelargonium odoratissimum into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise pelargonium odoratissimum after repotting?

Not immediately. Wait about 3 weeks after repotting pelargonium odoratissimum. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
