Anthurium Black Sweet × Goliath Care Guide :

Light Requirements

Provide bright, indirect light for optimal growth. An east- or north-facing window is ideal, or place the plant a few meters away from a bright south-facing window with sheer curtains. Direct sunlight can scorch the leaves, causing pale patches or burns, while very low light may slow growth and reduce leaf size and color intensity. Consistent indirect light encourages healthy, large foliage and strong veins.

Watering

Water the Anthurium Black Sweet × Goliath when the top 2–3 cm of the growing medium feels slightly dry. Use room-temperature, filtered, or rainwater whenever possible, as Anthuriums are sensitive to salts and chemicals found in hard water. Overwatering can lead to root rot, while underwatering may cause leaf drooping and dry edges. Ensure excess water drains freely and never allow the plant to sit in standing water.

Humidity

This hybrid thrives in high humidity levels of 65–85%. In drier indoor environments, especially during summer or when using air conditioning, increase humidity by using a humidifier or placing the plant on a pebble tray with water. Grouping plants together can also help maintain a humid microclimate. Adequate humidity promotes larger leaves, richer coloration, and smoother leaf texture.

Temperature

Maintain temperatures between 18°C and 30°C, which suits most Indian homes well. Protect the plant from sudden temperature drops, cold drafts, or exposure below 15°C, as this can slow growth and stress the plant. Avoid placing it near air conditioners, heaters, or open windows during cool nights.

Growing Medium

A well-draining, airy mix is essential. Use a chunky Anthurium or aroid mix consisting of coco chips, orchid bark, perlite, charcoal, and a small amount of coco peat or sphagnum moss. This mimics the plant’s natural epiphytic environment, allowing roots to breathe while retaining sufficient moisture. Poorly draining soil is the most common cause of root problems.

Fertilizing

Feed the plant every 3–4 weeks during the active growing season (spring and summer) using a balanced liquid fertilizer diluted to half strength. Organic options like seaweed extract or vermicompost tea are also beneficial. Avoid over-fertilizing, as excess nutrients can cause salt buildup and leaf damage. Reduce feeding during cooler months when growth slows.

Repotting

Repot every 12–18 months or when roots start emerging from the drainage holes. Choose a pot only slightly larger than the previous one to prevent excess moisture retention. Repotting refreshes the growing medium and provides space for healthy root expansion.

Pruning and Maintenance

Remove yellowing or damaged leaves using clean, sterilized scissors. Wipe leaves gently with a damp cloth to remove dust and help the plant photosynthesize efficiently. Healthy leaves with a natural sheen indicate good care and proper humidity.

Pests and Diseases

Watch for common pests such as spider mites, mealybugs, and thrips. Inspect the underside of leaves regularly. Treat infestations early using neem oil or mild insecticidal soap. Most fungal issues arise from overwatering or poor airflow, so maintain proper watering habits and ventilation.

Final Thoughts

With the right balance of light, humidity, and moisture, Anthurium Black Sweet × Goliath will reward you with dramatic foliage and strong, steady growth. Its bold appearance makes it a true statement plant, perfect for collectors seeking a rare and luxurious Anthurium hybrid.
