Aeschynanthus radicans grows best in a loose, organic-rich mix that balances moisture retention with air flow for healthy roots.
Soil Texture
Loamy, Peaty, Organic-rich
Soil pH
Acidic (5.5–6.5), Slightly acidic (6.5–7.0)
Soil Drainage
Moist but well-drained
Native to tropical Southeast Asia, Aeschynanthus radicans grows in warm, humid forests where roots stay lightly moist but still get good airflow. That background explains why it prefers a loose, organic-rich substrate rather than anything dense or heavy.
The best soil for Lipstick plant holds some moisture yet drains freely, with a soft loamy to peaty texture that keeps oxygen around the roots. Its root system benefits from steady moisture and air at the same time, so the substrate should feel open, lightly acidic, and never compacted.
A simple homemade mix gives Aeschynanthus radicans the balance of moisture retention and air space its roots handle well in containers.
The finished mix should feel springy, light, and slightly crumbly, with water moving through evenly instead of pooling.
A slightly acidic to mildly acidic range of about 5.5–6.8 suits Lipstick plant well. In that range, key nutrients stay more available to the roots and are easier for the plant to take up.
If the mix drifts far above or below that range, nutrient uptake can become less efficient even when the soil otherwise looks suitable. Aeschynanthus radicans can handle small variation, but it performs best near the middle of that range.
This species can react poorly when the root zone stays stressed for long periods. Soil conditions are one possible factor to check when growth seems off.
Compaction: if the surface hardens and water stops soaking in evenly, gently loosen only the top layer and plan to refresh the mix soon.
Soggy root zone: if the container stays heavy for too long and the mix feels swampy, improve drainage and remove any trapped excess water.
Fast collapse of mix: older organic material can break down into a dense mass, so replace tired soil that no longer feels airy.
Salt buildup: a crust on the soil surface may point to mineral accumulation, so flush the potting mix thoroughly and monitor future residue.

Find the right soil mix for your plant and support healthier root growth
Botan helps match this plant to a more suitable soil setup based on its growth habit, container use, and care conditions.
Yes. Drainage holes help excess water leave the container, which keeps the root zone from staying saturated too long and supports a healthier Lipstick plant soil environment overall.
Botan can help assess visible issues and show whether soil conditions may be part of the problem through photo-based plant checks.
