Anthurium Hearts Afire Care Guide: Keeping Those Velvet Leaves Happy

Some plants catch your attention with flowers. Anthurium Hearts Afire makes its impression with foliage: heart-shaped velvet leaves, delicate creamy veins, and new growth that emerges with bronze-red tones before deepening to green.

Sold as Arching Amour™ Heart’s Afire™, this Anthurium hybrid is one to appreciate up close. Watching a fresh leaf change color is part of the appeal—and a reason to leave room beside it for the next one. (provenwinners.com)

Light: Bright Indirect

Give those leaves good light without harsh sun.

Choose a bright location with filtered daylight. An east-facing window can be a useful starting point, while stronger exposures may need a sheer curtain.

Avoid intense direct sunlight, which can damage foliage. A dark corner isn’t ideal either: insufficient light can slow growth. Aim for a spot where the plant receives consistent daylight rather than choosing its location purely for decoration. (whiteflowerfarm.com)

Water: When the Top 1–2 Inches Dry

Let the surface dry while deeper roots retain some moisture.

Check the mix before reaching for the watering can. For Hearts Afire, a practical starting point is to water once the upper inch or two feels dry, without leaving the entire root ball completely parched.

Bottom watering is an option: set the nursery pot in room-temperature water, allow the mix to absorb moisture, then remove it and drain thoroughly. Never leave the pot standing in water afterward. (provenwinners.com, whiteflowerfarm.com)

Humidity: 60% or Higher Preferred

A humidifier can help in a dry room.

Proven Winners recommends humidity of at least 60% for Anthuriums. A room humidifier can provide additional moisture when household air is dry.

Keep temperatures around 65–85°F and position the plant away from heating vents, air-conditioning blasts, and cold drafts. (provenwinners.com)

Soil: Airy and Free-Draining

Give water a way out.

An orchid-style mix or potting soil amended with coarse ingredients can help prevent a dense, waterlogged root environment. White Flower Farm suggests an orchid mix or an equal-parts blend of potting soil and perlite.

Whatever mix you choose, use a pot with drainage holes and empty collected runoff. (whiteflowerfarm.com)

Fertilizer: Gentle Feeding During Growth

Use a diluted houseplant fertilizer during active growth, following the product’s directions. Proven Winners suggests monthly feeding at half strength during spring and summer.

When growth slows, reduce or pause feeding. (provenwinners.com)

Repotting and Routine Maintenance

Check the roots before deciding to repot. If they have filled the container, move up just one pot size and refresh the mix. Remove dead or damaged leaves with clean tools.

Wear gloves when pruning or dividing: Anthurium sap can irritate skin. Keep the plant out of reach of pets and children who might chew it. (provenwinners.com, whiteflowerfarm.com)

When Something Looks Wrong

Brown edges or discolored leaves aren’t a diagnosis by themselves. Start by checking the soil and drainage; both excessive watering and insufficient watering can contribute to browning.

Before changing several things at once, take a photo and note what you observe. That gives you something concrete to compare with later. (whiteflowerfarm.com)

Caring for Hearts Afire also gives you an excuse to slow down and look closely. Notice the newest leaf, its changing color, and the details in its veins. There’s plenty to enjoy before it becomes a large specimen.
