About Hoya Blashernaezii

Hoya blashernaezii · also called Blasher-Naez' hoya · houseplant

Hoya blashernaezii is a Philippine epiphytic vine with slender stems and narrow, semi-succulent green leaves. It blooms readily and prolifically, producing clusters of small, fragrant yellow flowers with a paler corona and a scent often likened to butterscotch. An easygoing, fast-flowering hoya that thrives in bright indirect light and a fast-draining mix.

Preferred mix: Light, free-draining epiphytic mix

Watch for — Root rot from overwatering: The semi-succulent leaves mean it stores water and dislikes constant moisture. Let the mix dry partway between waterings and use an airy, free-draining medium to keep roots healthy.

Why hoya blashernaezii needs this mix

Hoya Blashernaezii drinks mostly through its central cup, not its roots — so it wants a light, open, fast-draining bark mix and only a shallow pot.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons hoya blashernaezii struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Potting hoya blashernaezii deep in ordinary compost as if the roots do the feeding. Use a shallow pot of open bark mix and keep the soil only barely moist.

pH — does it matter for hoya blashernaezii?

Hoya Blashernaezii likes a slightly acidic mix (around pH 5.0-6.0), which a bark-based blend gives naturally. Cup-water quality matters more than soil pH — use rain or filtered water.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

A bagged epiphytic or orchid mix works well for hoya blashernaezii with a little extra perlite. The DIY ratio above is easy and cheap if you already keep orchids.

Drainage and the pot

A shallow, well-drained pot is ideal — the rootball should never sit in water. Keep the central cup topped up instead; that is how the plant actually drinks.

Hoya Blashernaezii rarely needs repotting — it flowers once then produces pups. Move pups to fresh bark mix; bark breakdown is slow enough that the parent rarely needs it. When the time comes, our repotting guide for hoya blashernaezii covers the timing and technique step by step.
