About Swedish Ivy

Plectranthus verticillatus · also called Swedish ivy, Swedish begonia · houseplant

Swedish ivy is a fast-growing, trailing member of the mint family (not a true ivy), prized as an easy, pet-safe houseplant for hanging baskets and shelves. Its one defining need is bright, indirect light with evenly moist but never soggy compost; direct sun scorches its glossy, scalloped leaves and waterlogging rots its shallow roots.

Mature size: Trailing stems reaching around 0.5-1 m long, with a low mounded height of about 10-30 cm; reaches full size within 1-2 years.

Watch for — Root rot / wilting: Caused by overwatering or soggy compost; the plant wilts and stems blacken. Often easier to take healthy stem-tip cuttings and start afresh than to save a badly rotted parent.

How to tell swedish ivy needs repotting

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

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new swedish ivy leaves are noticeably smaller than older ones despite good light.

How often to repot swedish ivy

Every 12–18 months — sooner if roots show fast. Swedish Ivy's growth habit — a vigorous, mounding-then-trailing evergreen perennial with square mint-family stems and rounded, scalloped, glossy green leaves that release a faint scent when brushed. indoors it spills attractively from hanging baskets and shelves, spreading roughly 0.5-1 m, and produces small tubular white or pale-purple flowers intermittently. — sets the pace. Swedish ivy is a fast-growing, trailing member of the mint family (not a true ivy), prized as an easy, pet-safe houseplant for hanging baskets and shelves. Its one defining need is bright, indirect light with evenly moist but never soggy compost; direct sun scorches its glossy, scalloped leaves and waterlogging rots its shallow roots.

What size pot to step swedish ivy up to

Step up one pot size — about 2–3 cm (an inch) wider. Swedish Ivy grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

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 swedish ivy

Early spring, just as new growth restarts, is the ideal window for swedish ivy. 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 swedish ivy

Time it for spring. Repot swedish ivy 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 swedish ivy 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-based potting compost 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

Water swedish ivy once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for swedish ivy

Swedish Ivy wants free-draining, loam-based potting compost. Use any good-quality, well-drained potting mix; a peat-free, loam-based compost (such as John Innes No.2) lightened with extra perlite or grit suits it well. It tolerates acid, neutral or alkaline pH. Repot annually in spring to refresh the mix and extend the plant's life. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting swedish ivy — frequently asked questions

How often should you repot swedish ivy?

Every 12–18 months — sooner if roots show fast for swedish ivy. Repot swedish ivy roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh free-draining, loam-based potting compost. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does swedish ivy need?

When is the best time of year to repot swedish ivy?

Can you put swedish ivy straight into a much bigger pot?

No. Even a fast-growing swedish ivy 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 swedish ivy after repotting?

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