About Homalomena Sp. Selby

Homalomena sp. 'Selby' · also called Selby homalomena, dark-leaf queen of hearts · tropical

Homalomena sp. 'Selby' is a clumping tropical aroid grown for its deep green to near-black, glossy, heart-shaped leaves on upright petioles. A robust understorey plant, it is more forgiving than many fussy aroids while still rewarding warmth, humidity and bright shade. Its dense, low mound of dark foliage makes an easy, architectural houseplant.

Mature size: 45-75 cm (18-30 in) tall with a similar spread.

Watch for — Yellowing leaves: Commonly overwatering or poor drainage; let the surface dry between waterings and ensure the pot drains freely.

How to tell homalomena sp. selby needs repotting

Repotting on a calendar is less reliable than reading the plant. For homalomena sp. selby, 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 homalomena sp. selby) 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 homalomena sp. selby

Only every 2–4 years, when genuinely crowded. Homalomena Sp. Selby 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. Clump-forming, rhizomatous evergreen aroid producing a dense mound of upright, long-stalked heart-shaped leaves from the base..

What size pot to step homalomena sp. selby up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Homalomena Sp. Selby 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 homalomena sp. selby 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.

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 homalomena sp. selby

Early spring, just as new growth restarts, is the ideal window for homalomena sp. selby. 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 homalomena sp. selby

Confirm it actually needs it. Slide homalomena sp. selby 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 homalomena sp. selby 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 rich, free-draining aroid 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 homalomena sp. selby 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 homalomena sp. selby

Homalomena Sp. Selby wants rich, free-draining aroid mix. A loose, airy blend of potting compost with bark, perlite and coir holds moisture while draining freely. Slightly acidic pH suits it; good drainage prevents root 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 homalomena sp. selby — frequently asked questions

How often should you repot homalomena sp. selby?

Only every 2–4 years, when genuinely crowded for homalomena sp. selby. Only repot homalomena sp. selby 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 rich, free-draining aroid mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does homalomena sp. selby need?

When is the best time of year to repot homalomena sp. selby?

Does homalomena sp. selby like to be root-bound?

Yes — homalomena sp. selby 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 homalomena sp. selby after repotting?

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