Anubias barteri Care

This slow-growing aquatic plant prefers gentle, indirect light rather than direct, intense sun.

• Provide 8–10 hours of low to moderate light daily, such as filtered daylight or subdued aquarium lighting, avoiding strong midday sun that can scorch leaves and promote algae.
• Allow partial shade in tanks or ponds; position Anubias barteri under taller plants, driftwood, or rock overhangs so light reaches it indirectly.
• In summer, shield from harsh afternoon sun with shading material; in darker winter months, extend artificial light duration by 1–2 hours to maintain steady growth.

This rhizomatous aquatic plant prefers stable moisture around the roots and rhizome without prolonged stagnation in debris-filled water.

• When grown submerged, maintain clean, well-filtered water with gentle flow and perform partial water changes weekly to prevent waste buildup that can stress leaves and roots.
• In emersed setups, keep the substrate consistently moist but not waterlogged; allow only the top 0.5–1 cm to begin drying before misting or rewetting around, not over, the rhizome.
• Watch for yellowing, mushy leaves or rhizome as signs of overwatering or poor water quality, and brown, crispy edges as signs of drying or insufficient humidity around the plant.

This tropical aquatic species prefers stable, warm conditions and reacts poorly to rapid temperature swings.

• Aim for 72–82°F (22–28°C) for steady growth, which suits most heated aquariums and warm indoor or greenhouse setups.
• Avoid letting water or air temperatures drop below 68°F (20°C) for long periods; brief dips to 64°F (18°C) may be tolerated but slow growth and increase disease risk.
• Protect from frost and strong heat above 86°F (30°C); in hot weather, increase aeration and shade, and in cooler seasons use a reliable heater to keep conditions stable.

This species stays healthy across a wide humidity range but prefers moderately moist air.

• Target 40–70% humidity, which matches most indoor rooms and typical aquarium surrounds.
• Dry air rarely harms leaves but may slow growth; persistent leaf edge browning can indicate low humidity or airflow issues.
• Increase humidity locally with an open-top water dish nearby or by positioning the plant close to, but not directly above, an aquarium housing Anubias barteri.

In aquariums, this plant attaches to hardscape rather than rooting in conventional soil or substrate.

• Use inert, stable materials like rock, driftwood, or coarse gravel; avoid burying the rhizome, which must sit fully above the substrate to prevent rot.
• If using nutrient substrate, only the fine roots may enter it lightly while the thick rhizome rests on top, allowing water flow and oxygen around the plant base.
• Maintain gentle water movement so detritus does not pack densely around the rhizome, which would reduce aeration and encourage decay.
• For emersed setups, place the rhizome on moist, loose media such as fine bark and sand mix, never pressed into compact, anaerobic sludge.

This species is very suitable for container culture in both aquariums and emersed setups.

• Choose a stable, relatively heavy container so attached rocks or driftwood do not tip when the plant mass increases on one side.
• Ensure the planting base or basket has wide openings so water circulates freely around the rhizome while still holding stones or media in place.
• In emersed trays or shallow tubs, keep only the roots and lower rhizome in shallow water while the leaves remain above, which reduces rot from constant submersion at the crown.

This slow-growing aquatic species needs only light, occasional nutrition to maintain healthy foliage.

• Use a balanced liquid NPK fertilizer made for aquariums at 1/4 strength to avoid algae issues.
• Dose every 3–4 weeks during the main growth period, adjusting based on leaf color and vigor.
• Skip or greatly reduce dosing in winter or when tank growth is very slow.
• Rely mainly on clean water and stable conditions; heavy feeding is unnecessary for Anubias barteri.

Pruning is mainly used to keep Anubias barteri compact and to remove declining foliage under water.

• Trim yellow, melted, or damaged leaves at the base of the petiole using sharp aquascaping scissors.
• Remove a few crowded leaves to improve light penetration to lower parts of the plant.
• Cut older leaves first to encourage new, compact growth from the rhizome.
• Inspect during routine tank maintenance and combine pruning with water changes to reduce stress.

This rhizomatous aquarium plant is usually attached to hardscape rather than potted, so repotting is infrequent.

• Consider moving the plant when the rhizome overgrows its rock or wood, or when growth stalls in an established tank.
• Transplant during stable conditions, ideally in the main growing period, not right after major tank changes.
• Gently detach the rhizome, preserving as many roots as possible, and re-tie it loosely to new decor.
• Avoid burying the rhizome in substrate; keep it exposed to water flow to reduce rot and transplant stress.

Anubias barteri is commonly propagated by division of the rhizome rather than by seed in home aquariums.

• Best time for division is during active growth when the plant has a thick, multi-eyed rhizome.
• Use a clean, sharp blade to cut the rhizome into sections, each with 3–5 healthy leaves and roots.
• Attach divisions to rocks or wood and keep them in moderate light with stable temperature and clean water.
• Maintain gentle water flow around new pieces to discourage rot and support root development.

As a tropical aquarium plant kept indoors, Anubias barteri usually needs minimal winter-specific care.

• Maintain stable water temperature around 72–80°F using a reliable heater in cooler months.
• Avoid placing tanks near drafty windows where sudden temperature drops can stress the plant.
• Keep lighting duration consistent, about 8–10 hours, even in shorter winter days to prevent decline.
