Full Guide on Growing White Anthuriums With 100% Success

Over the years, I’ve grown a wide variety of plants, but there’s something uniquely elegant about white anthuriums. With their glossy green leaves and pristine white, waxy blooms, they bring a sense of calm and sophistication to any space.

While they may look delicate, these tropical beauties are surprisingly easy to grow if you give them the right care.

Whether you want to keep them indoors as a houseplant or add them to a shaded outdoor garden, I’ll share my firsthand experience on how to successfully grow and maintain white anthuriums.

Understanding White Anthuriums

White anthuriums (Anthurium andreanum or Anthurium scherzerianum) are part of the Araceae family and originate from the rainforests of Central and South America. They are often called “flamingo flowers” due to their striking appearance.

Unlike true flowers, the white part you see is actually a modified leaf known as a spathe, which surrounds the spadix, the actual flower structure.

These plants can bloom year-round under the right conditions, making them a rewarding addition to any home or garden.

Choosing the Right Growing Conditions

White anthuriums thrive in conditions that mimic their tropical origins. They prefer warmth, humidity, and indirect light. I’ve found that the secret to keeping them happy is replicating the gentle, dappled sunlight they’d receive under a rainforest canopy. Placing them in the wrong location, like direct harsh sunlight or a cold, drafty spot, can quickly lead to stress.

• Light: These plants love bright, indirect light. A north- or east-facing window works well indoors, while in outdoor gardens, they should be placed in a shaded spot. Direct sun can scorch their leaves, leaving unsightly brown spots.
• Temperature: The ideal range is between 65–80°F (18–27°C). Avoid sudden temperature drops, as these tropical plants dislike cold weather. If you’re growing them outdoors, make sure to bring them inside before temperatures dip below 55°F (13°C).
• Humidity: White anthuriums thrive in humidity levels above 50%. If you live in a dry climate, a humidity tray or regular misting will help. In my experience, grouping them with other tropical plants or placing a small humidifier nearby keeps them looking lush.

Selecting the Best Soil and Pot

Like many tropical plants, white anthuriums prefer light, well-draining soil that retains some moisture without becoming soggy. A mix of orchid bark, perlite, and peat moss works beautifully.

I like to add a bit of charcoal to the mix, as it helps improve drainage and prevents root rot. If you’re using a store-bought mix, a high-quality aroid or orchid mix will do the job.

When choosing a pot, go for one with drainage holes to prevent water from sitting at the bottom. These plants don’t like “wet feet,” and letting them sit in standing water is a quick way to invite fungal problems. I’ve found that terracotta pots work well because they allow excess moisture to evaporate.

Watering Tips for Healthy Growth

Getting the watering schedule right is key. Too much water, and the roots will rot. Too little, and the plant will wilt. During warmer months, I water my white anthuriums about once a week. In cooler months, I let the top inch of soil dry out before watering again.

If you have hard water, it’s best to use filtered or rainwater. Tap water with high chlorine levels can sometimes cause brown tips on the leaves.

Instead of watering on a set schedule, I always check the soil with my finger. If the top layer is dry, it’s time to water. If it’s still damp, I wait a few more days.

Fertilizing for Bigger and Better Blooms

Anthuriums are moderate feeders and benefit from regular fertilization. I use a balanced liquid fertilizer (like a 20-20-20 mix) diluted to half strength every six to eight weeks during the growing season. A slow-release fertilizer also works well, but be sure not to overdo it—too much fertilizer can cause salt buildup in the soil.

To encourage more blooms, I sometimes switch to a fertilizer with higher phosphorus content (like a bloom booster formula). This helps promote strong flower production while keeping the plant healthy.

Repotting and Propagation

White anthuriums don’t need frequent repotting, but they do appreciate fresh soil every couple of years. I usually repot mine when I see roots growing out of the drainage holes or when the plant becomes root-bound. Spring is the best time to do this, as the plant is actively growing.

When repotting, I also take the opportunity to propagate my anthuriums. The easiest method is by dividing the plant at the roots.

I simply separate a healthy clump with at least a few leaves and its own root system, then plant it in a new pot with fresh soil. Within a few months, the new plant will establish itself and start producing blooms.

Common Problems and How to Fix Them

Despite being relatively low-maintenance, white anthuriums can sometimes develop issues. Here are a few common ones I’ve encountered and how to fix them:

• Brown leaf tips: This is usually a sign of low humidity or over-fertilization. Increasing humidity or flushing the soil with fresh water can help.
• Yellowing leaves: Overwatering is the main culprit. Let the soil dry out a bit between waterings and make sure your pot has good drainage.
• No blooms: If your plant isn’t blooming, it might not be getting enough light. Moving it to a brighter spot (without direct sun) and feeding it with a phosphorus-rich fertilizer can encourage flowers.
