Plant Care 101: How to Care for Anthuriums
Introduction
Anthurium is a genus of about 1,000 species of flowering plants, making it the largest genus of the arum family, Araceae. Here at GrowTropicals, Anthuriums are one of our team's favourite plant species. We love growing aroids in our HQ, and the leaves on our bigger Anthuriums especially stand out in our collection for their big velvety leaves with contrasting silver veins.
Anthuriums are becoming more and more popular within the plant world. Whilst they are relatively easy to care for, they require specific conditions for them to thrive.
In this guide, we will go through their preferred lighting, humidity and soil type, as well as identify common Anthurium problems.
💡 Did you know
Did you know that the spathe of an Anthurium is actually a modified leaf? The true flowers are the tiny structures found on the spadix, the spike that protrudes from the spathe. This unique structure helps attract pollinators and adds to the plant’s tropical and rare appeal.
What Lighting Do Anthuriums Prefer?
Anthuriums thrive in bright, indirect light. They are native to tropical rainforests where they grow under the canopy of larger trees, so they are accustomed to dappled sunlight. Direct sunlight can scorch their leaves, while too little light can cause them to grow slowly and produce fewer spathes. Place your Anthurium near a north or east-facing window, or use sheer curtains to diffuse the light if necessary.
💡In the winter months, natural sunlight can be scarce. To ensure your Anthurium gets enough light, we recommend using grow lights to supplement the lack of natural sunlight. Position the grow lights 12-18 inches above the plant and leave them on for 12-14 hours a day to mimic the longer daylight hours of the growing season.
How Often Should I Water My Anthurium?
Anthuriums prefer consistently moist but not waterlogged soil. Water your plant when the top inch of soil feels dry to the touch. Depending on the climate and season, this might be once a week or more frequently in warmer months. Always ensure the pot has drainage holes to prevent water from sitting at the bottom and causing root rot. Overwatering is a common issue, so it's better to underwater slightly than to overdo it.
When Should I Repot My Anthurium?
Repotting Anthuriums should be done every 2-3 years, or when you notice the plant becoming root-bound (roots growing out of the pot's drainage holes). Spring is the best time to repot, as the plant will be entering its growing season and can recover more quickly. Choose a pot that is one size larger than the current one, and ensure it has good drainage.
Choosing the right potting mix is crucial for the health of your Anthurium. Our premium Anthurium Potting Mix is a peat-free blend designed specifically for epiphytic Anthuriums or situations requiring an even chunkier mix than our excellent Jungle Mix.
The specially created substrate is composed of bark, charcoal, coco husk, lava rock, and pumice, providing a long-lasting structure and excellent drainage to prevent overwatering. Additionally, worm castings are included for natural fertilisation and healthy growth.
Common Anthurium Issues
Yellow Leaves:
This can be caused by overwatering, poor drainage, or low humidity. Ensure your Anthurium is in well-draining soil and that you are not overwatering it. Increasing the humidity around the plant can also help.
Brown Tips
Often a sign of low humidity or over-fertilisation. Make sure your Anthurium is kept in a high-humidity location (preferably 60-80%) or is near a humidifier. Be sure to reduce the fertilisation schedule during the winter months.
Lack of inflorescence:
Insufficient light is the most common cause for your Anthurium not to bloom. Ensure your Anthurium is getting bright, indirect light. Repotting in fresh potting mix can also stimulate flowering.
Pests:
Common pests include gnats, mealybugs, and spider mites. With a microfibre cloth, wipe the leaves with a damp cloth regularly and use insecticidal soap if you notice an infestation.
