About Fishtail Parlour Palm

Chamaedorea ernesti-augusti · also called Fishtail Parlour Palm, Ernest August's Palm · houseplant

A distinctive, slow-growing understorey palm from the tropical forests of Mexico, Belize, and Guatemala, notable for its unusual simple, undivided leaves (rather than feathery fronds) that are deeply notched at the tip, giving them a two-lobed fishtail shape. It is highly shade-tolerant and compact, making it well-suited to low-light indoor rooms and conservatories. Temperature must stay above 10°C at all times — sudden cold draughts cause irreversible frond damage. Chamaedorea ernesti-augusti is considered non-toxic to cats and dogs.

Mature size: Typically 60–120 cm tall and 45–75 cm wide as a container plant; rarely exceeds 1.5 m indoors.

How to tell fishtail parlour palm needs repotting

Repotting on a calendar is less reliable than reading the plant. For fishtail parlour palm, watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and fishtail parlour palm wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

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 fishtail parlour palm

Every 2–3 years; top-dress in the in-between years. Fishtail Parlour Palm's growth habit — solitary-stemmed or sparsely clustering palm with distinctive simple, bifid (two-lobed) leaves; very slow-growing, making it an excellent long-term indoor specimen. — sets the pace.

What size pot to step fishtail parlour palm up to

Move up exactly one pot size. A heavy fishtail parlour palm dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

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 fishtail parlour palm

Early spring, just as new growth restarts, is the ideal window for fishtail parlour palm. 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 fishtail parlour palm

Consider top-dressing first. If fishtail parlour palm is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh well-drained, peat-free compost with perlite beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave fishtail parlour palm in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave fishtail parlour palm in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for fishtail parlour palm

Fishtail Parlour Palm wants well-drained, peat-free compost with perlite. A mix of peat-free multipurpose compost and 30–40% perlite works well; adequate drainage is critical as the roots are sensitive to anaerobic conditions in heavy, compacted compost. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting fishtail parlour palm — frequently asked questions

How often should you repot fishtail parlour palm?

Every 2–3 years; top-dress in the in-between years for fishtail parlour palm. Fully repot fishtail parlour palm only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with well-drained, peat-free compost with perlite. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does fishtail parlour palm need?

When is the best time of year to repot fishtail parlour palm?

Should you top-dress or fully repot fishtail parlour palm?

For a big, heavy fishtail parlour palm, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise fishtail parlour palm after repotting?

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