Anthuriums prefer a well-aerated and slightly acidic potting mix. A mix of orchid bark, perlite, and peat moss works well to ensure proper drainage. The soil should retain moisture without becoming waterlogged. Repotting every two to three years can help refresh the soil and provide essential nutrients for continued healthy growth.
4. Fertilizer
During the growing season, typically spring and summer, feed your anthuriums with a balanced liquid fertilizer every six to eight weeks. Dilute the fertilizer to half or quarter strength to prevent over-fertilization. Reduce or cease fertilization in the fall and winter when the plant experiences a period of dormancy.
How To Encourage Anthuriums To Bloom
1. Provide Adequate Light
Ensure anthuriums receive bright, indirect light for at least six hours a day. Adequate light exposure is crucial for stimulating flowering. However, avoid direct sunlight, which can cause leaf burn.
2. Maintain Optimal Temperature
Anthuriums thrive in temperatures between 65°F to 80°F (18°C to 27°C). The key is to maintain consistent warmth to encourage flower production. Avoid exposing them to temperatures below 50°F (10°C) or drafts, as it can hinder blooming.
3. Humidity
Anthuriums prefer higher humidity levels. If you live in a dry climate or during the winter months when indoor heating reduces humidity, consider placing a tray filled with water near the plant or using a humidifier.
4. Appropriate Fertilization
During the growing season, provide anthuriums with a balanced liquid fertilizer. A fertilizer higher in phosphorus (the middle number on the fertilizer label) can promote flower development.
5. Remove Spent Blooms
To encourage the production of new flowers, you should promptly remove faded or spent blooms. This redirects the plant’s energy towards the development of new buds.
6. Prune And Shape
Pruning anthuriums is needed to maintain a desirable shape and encourage new growth. Be mindful not to remove healthy leaves, as they contribute to the overall vigor of the plant continues on the next page.
