About Pilea peperomioides 'Mojito'

Pilea peperomioides 'Mojito' · also called Mojito Chinese money plant, variegated UFO plant · houseplant

Pilea peperomioides 'Mojito' is a variegated sport of the popular Chinese money plant, its round, coin-like leaves splashed and speckled with creamy-yellow flecks on long petioles. It keeps the easy, upright UFO-plant charm but with painterly variegation. It wants bright indirect light, a free-draining mix and water only when the topsoil dries. It is pet-safe.

Mature size: Reaches about 20-30 cm tall and wide indoors, with the trunk thickening and lengthening over time.

Watch for — Yellowing lower leaves: Usually overwatering. Let the soil dry further between waterings and confirm the pot drains freely.

How to tell pilea peperomioides 'mojito' needs repotting

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

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for pilea peperomioides 'mojito') flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

How often to repot pilea peperomioides 'mojito'

Only every 2–4 years, when genuinely crowded. Pilea peperomioides 'Mojito' is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. An upright, single-stemmed grower that produces a rosette of long-stalked round leaves and readily sends up baby plantlets (pups) from the base and roots..

What size pot to step pilea peperomioides 'mojito' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Pilea peperomioides 'Mojito' positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping pilea peperomioides 'mojito' into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

The best time of year to repot pilea peperomioides 'mojito'

Early spring, just as new growth restarts, is the ideal window for pilea peperomioides 'mojito'. 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 pilea peperomioides 'mojito'

Confirm it actually needs it. Slide pilea peperomioides 'mojito' out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip pilea peperomioides 'mojito' out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh well-draining, peat-free houseplant mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

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 pilea peperomioides 'mojito' 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 pilea peperomioides 'mojito'

Pilea peperomioides 'Mojito' wants well-draining, peat-free houseplant mix. An airy blend of peat-free compost with perlite and a little bark gives the sharp drainage this species needs. A neutral to slightly acidic pH suits it. Always use a pot with drainage holes; soggy mix is the quickest way to lose a Pilea. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting pilea peperomioides 'mojito' — frequently asked questions

How often should you repot pilea peperomioides 'mojito'?

Only every 2–4 years, when genuinely crowded for pilea peperomioides 'mojito'. Only repot pilea peperomioides 'mojito' every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using well-draining, peat-free houseplant mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does pilea peperomioides 'mojito' need?

When is the best time of year to repot pilea peperomioides 'mojito'?

Does pilea peperomioides 'mojito' like to be root-bound?

Yes — pilea peperomioides 'mojito' genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise pilea peperomioides 'mojito' after repotting?

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