Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Adjust the timing for the light at the plant, the pot’s size and material, and the humidity indoors. Terracotta dries faster than glazed ceramic.

Light and placement
Bright, indirect light
Arrowhead plant thrives in bright, indirect light. Direct midday sun can scorch the leaves. Place it 1–2 meters back from an east or west window, or behind a sheer curtain on a south window.
Feeding
Feed your arrowhead plant every 30 days while it’s actively growing. Use a balanced liquid houseplant fertilizer at half the strength on the label, and only on soil that’s already damp. Feeding dry roots can scorch them.
When growth pauses, skip the fertilizer and let it rest.
Temperature & humidity
Humidity40–70%
Chilling is possible below about 13 °C (55 °F). Keep the plant at 15 °C (59 °F) or warmer in winter.
It does best at 40–70% humidity. It doesn’t need misting.
Common problems
Yellowing, drooping, and dry edges often point to watering or drainage. Compare the signs before changing the routine.

Is arrowhead plant safe for cats and dogs?
The plant contains insoluble calcium oxalate crystals. Chewing it can cause oral irritation, drooling, and vomiting. Keep arrowhead plant out of reach of pets, or pick a non-toxic alternative like Fuchsia, mistletoe cactus, zebra haworthia, or false aralia.
Why is my arrowhead plant turning yellow or drooping?
Yellowing, drooping and brown tips can have several causes. Check the potting mix before adding water and follow this plant’s watering and rest instructions. If the mix is still wet, do not add more water. Check drainage and roots, then light, humidity, water quality and pests. Faded color or webbing alone does not show that the roots need water.
