About Anoectochilus roxburghii

Anoectochilus roxburghii · also called Roxburgh's Jewel Orchid, King of Jewel Orchids · houseplant

Anoectochilus roxburghii is a prized terrestrial jewel orchid grown for its dark velvety leaves laced with an intricate gold or coppery vein network. Native to Asian forest floors, it is more demanding than Ludisia, needing constant warmth, high humidity and an airy, moisture-retentive medium. Small white-and-yellow flowers appear on short spikes, but the foliage is the main draw.

Mature size: 8-15 cm tall, spreading 15-25 cm wide; flower spikes reach 10-20 cm.

How to tell anoectochilus roxburghii needs repotting

Repotting on a calendar is less reliable than reading the plant. For anoectochilus roxburghii, 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 anoectochilus roxburghii) 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.

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 anoectochilus roxburghii

Only every 2–4 years, when genuinely crowded. Anoectochilus roxburghii 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. Low creeping terrestrial orchid with a fleshy, prostrate rhizome that roots along its length, sending up short upright stems crowned with a rosette of patterned leaves..

What size pot to step anoectochilus roxburghii up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Anoectochilus roxburghii 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 anoectochilus roxburghii 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 anoectochilus roxburghii

Early spring, just as new growth restarts, is the ideal window for anoectochilus roxburghii. 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 anoectochilus roxburghii

Confirm it actually needs it. Slide anoectochilus roxburghii 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 anoectochilus roxburghii 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 live or fine sphagnum moss, or a humus-rich terrestrial orchid 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 anoectochilus roxburghii 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 anoectochilus roxburghii

Anoectochilus roxburghii wants live or fine sphagnum moss, or a humus-rich terrestrial orchid mix. Many growers use pure live sphagnum or a blend of fine bark, perlite and chopped moss that stays evenly moist while remaining airy around the delicate roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting anoectochilus roxburghii — frequently asked questions

How often should you repot anoectochilus roxburghii?

Only every 2–4 years, when genuinely crowded for anoectochilus roxburghii. Only repot anoectochilus roxburghii 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 live or fine sphagnum moss, or a humus-rich terrestrial orchid mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does anoectochilus roxburghii need?

When is the best time of year to repot anoectochilus roxburghii?

Does anoectochilus roxburghii like to be root-bound?

Yes — anoectochilus roxburghii 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 anoectochilus roxburghii after repotting?

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