How to care for Arrowhead Plant

sunlight

In tropical forests, Arrowhead Plant climbs through filtered canopy light. At home, give it bright, indirect light for fuller growth and stronger leaf color.

Bright indirect light

Place it near an east or north window, or a few feet back from a brighter window behind a sheer curtain. Variegated forms need this brighter placement to hold their pattern.

Medium light - tolerated

Green forms can manage a brighter room away from the window, but growth will slow and stems may stretch. Move it closer if new leaves are smaller or widely spaced.

Keep it out of hot, direct afternoon sun, which can bleach or scorch the leaves.

watering

Water thoroughly when the top 1-2 inches of soil feel dry, then let excess drain away. Arrowhead Plant likes lightly, consistently moist soil, but its roots should not sit wet.

Spring to early autumn

In bright, warm conditions, this is often about every 5-8 days. Check the soil rather than following the calendar: water once the upper layer is dry but the root ball still feels slightly moist.

Winter or low light

Growth slows, so watering may drop to roughly every 10-14 days. Let a little more of the mix dry before watering, especially in a cool room.

Lift the pot after watering and again before the next drink - a much lighter pot is a reliable sign it is drying out.

It will dry faster in brighter light, warmth, small terracotta pots, and airy soil. Larger pots, dense mixes, low light, and high humidity keep it moist longer.

Persistent soggy soil can cause root rot. Empty any saucer after watering and use a pot with drainage.

humidity

Relative humidity

50-70%

Arrowhead Plant comes from humid tropical forest understories, so it grows best with moderately humid air. Most homes are fine at 40-60%, but prolonged air below about 40% can slow growth.

Dry brown leaf edges, curling leaves, or new leaves that stick while unfurling usually mean the air is too dry, especially near heating or air conditioning.

Keep it away from radiators and group it with other plants to create a gentler, more humid pocket of air.

Run a humidifier nearby during dry winter weeks.
Use a pebble tray with water beneath the pot, keeping the pot above the waterline.
Give climbing plants a moss pole and keep the pole lightly moist if you want larger, more mature leaves.

temperature

Preferred range

18-27°C (65-80°F)

Winter minimum

15°C (59°F)

Native to warm, humid tropical forests, Arrowhead Plant grows best in steady indoor warmth. Cooler conditions slow growth and keep the potting mix wet for longer, while prolonged heat can cause dry leaf edges.

Keep it away from chilly windows, exterior doors, and heating or air-conditioning vents, especially overnight.

Cold drafts and temperatures below 15°C (59°F) can cause yellowing, limp leaves, and lasting damage.

nutrition

March - August

Feed about once a month with a balanced liquid houseplant fertilizer at half the label strength. Apply it to moist soil while the plant is making new leaves; stop feeding in winter or when growth has slowed.

Nitrogen

Nitrogen supports the lush leaf growth Arrowhead Plants are grown for. A balanced fertilizer supplies enough without pushing soft, weak growth.

Magnesium

Magnesium helps leaves stay green and supports photosynthesis. It is usually included in a complete houseplant fertilizer, so extra supplements are rarely needed.

Never fertilize a dry or stressed plant. Water first, and flush the pot with plain water if you see a white crust on the soil or pot.

soil

Airy, moisture-retentive soil

Arrowhead Plant likes roots that stay lightly moist but still get plenty of air. Use a loose houseplant mix with coco coir or peat, plus perlite and orchid bark to prevent compaction and let excess water drain freely.

pH 5,5 - 6,5

This is slightly acidic soil, which suits this aroid well. Most quality indoor plant mixes fall close to this range, so there is usually no need to adjust pH unless you use very alkaline water or garden soil.
