Give an arrowhead plant a moss pole and it can transform from a small trailing plant with cute heart-shaped leaves into a much bigger, more dramatic climber with deeply lobed leaves, far larger than the originals. It’s genuinely one of the more shape-shifting houseplants out there, and that adaptability is part of what makes it fun to grow.
Light
Bright, indirect light keeps growth full and, for variegated varieties, keeps the pink, cream, or white patterning vibrant. Direct sun can scorch the leaves, while low light is tolerated but leads to slower growth and fading color in variegated types.
Watering
Water when the top inch or two of soil has dried out, then water thoroughly until it drains from the bottom of the pot. Arrowhead plant is fairly forgiving of both slightly under and overwatering, but consistently wet soil over a long stretch is still the bigger risk.
Soil and potting
A well-draining potting mix with some added perlite works well. Repot every year or two as the plant grows, or when it becomes noticeably rootbound, moving up only one pot size at a time.
Humidity and temperature
Above-average humidity supports lusher growth but typical indoor conditions are tolerated reasonably well. It prefers average to warm room temperatures and should be kept away from cold drafts near doors and windows.
Fertilizing
A balanced liquid fertilizer diluted to about half strength, applied monthly during spring and summer, supports steady growth. Skip fertilizing in fall and winter when growth naturally slows.
Propagation
Arrowhead plant is one of the easier houseplants to propagate, stem cuttings with at least one node root readily in water or moist soil, usually within a couple of weeks. This makes it easy to keep an older, leggy plant looking full by regularly propagating and repotting cuttings back into the same container.
Climbing versus trailing
This is the defining choice with arrowhead plant, and it genuinely changes how the plant looks. Given a moss pole, trellis, or other support to climb, the plant matures faster and produces progressively larger, more deeply lobed leaves — NC State Extension confirms that if allowed to climb as it does in nature, the leaves eventually become pedate with 5 to 11 leaflets — eventually looking quite different from its young, arrow-shaped form. Left to trail or kept pruned back, it stays more compact with the simpler juvenile leaf shape most people associate with the plant. Neither approach is more correct, it comes down to which look you’re after, and you can switch a climbing plant back toward a bushier look with a hard prune if you change your mind.

Common problems
Drooping is usually tied to underwatering or overwatering, our full guide on why arrowhead plant is drooping walks through how to tell these apart, along with the normal leaf-shape changes that come with maturity. If the base feels soft or mushy, root rot is worth checking for directly.
A few things people ask
Is arrowhead plant toxic to pets? Yes, the ASPCA lists arrow-head vine as toxic to cats and dogs due to insoluble calcium oxalates and can cause mouth irritation if chewed, keep it out of reach of curious pets.
Why did my plant’s leaves change shape and color after I moved it? A change in light is the most likely explanation, brighter light tends to produce more vibrant variegation and can accelerate the shift toward more mature, lobed leaves, while a dimmer spot slows both.
How fast does it grow? Growth is moderate to fast in good conditions, especially once it’s climbing, a plant given a pole and consistent care can noticeably increase in size within a single growing season.
Can I keep multiple cuttings in the same pot for a fuller look? Yes, planting several rooted cuttings together is a common way to get a fuller-looking plant faster than waiting for a single stem to bush out on its own.
