About Ficus Black
Black, also known as the ‘Black Knight’ rubber plant, is a stunning cultivar of the Ficus Elastica species. This houseplant has prominent, glossy dark green leaves that appear almost black, giving it its distinctive name. The contrast between the dark green foliage and the vibrant red growth tips creates a striking visual appeal that rivals any flower.
Watch out for common problems like leaf drop, which can be caused by sudden environmental changes, flooding, or low humidity. Pests such as spider mites, mealybugs and scale insects may also affect this plant.
How often should I water my Ficus Black?
This plant needs evenly moist but well-drained soil. When the topsoil is dry, water it thoroughly and allow the excess soil to drain. Avoid overwatering or drying the soil completely. A well-drained potting mix with perlite, peat moss is ideal.
Light requirements of Ficus Black
Ficus Black grows in bright and indirect light. While it can tolerate less light conditions, it prefers a place near a sunny window, but direct sunlight can damage the plant in the long run and burn its leaves.

How much will it grow?
Feed ficus black with a balanced liquid fertilizer every 4 to 6 weeks during the growing season (spring and summer). Prune stems to maintain desired shape and enhance shine.
Temperature and humidity
Black ficus grows in a warm environment with bright, indirect sunlight or partial shade. It prefers temperatures between 65°F and 80°F (18–27°C) and requires humidity above 40%.
Troubleshooting common problems with Ficus Black
- Changing the pot: When the plant gets bigger and the current pot does not have enough room to grow, move it to a bigger pot. This allows the roots to grow properly and the plant to grow better.
- Cleaning the leaves: As the new leaves are growing, remove the old and dry leaves from the plant to make it a more beautiful specimen and also to prevent the occurrence of diseases and pests.
- Moving: Do not move the plant frequently, as this may cause shock and drop the leaves.
- Pests and diseases: Be careful that pests such as spider mites, aphids and weevils do not attack the plant. If you see pests, wash the leaves with mild soapy water or use appropriate insecticides.
- Sudden environmental changes: avoid sudden changes in temperature and light, because the plant may be sensitive to these changes and get stressed.
