Ficus Lyrata – Complete Growing Guide with LED Lighting

Lighting conditions

The fiddle-leaf fig needs plenty of light, but indirect light: its leaves will burn in direct sunlight. Experts recommend 12 to 14 hours of intense indirect light per day. A location near an east- or west-facing window is ideal, as it benefits from the soft morning or afternoon light without direct sunlight. In winter or in dimly lit interiors, supplement with horticultural LED lighting to maintain a consistent light level.

Models TerraLED recommended

• Lamp TerraLEDTM PRO (30 cm, 60 cm, 90 cm or 120 cm): These LED bars provide balanced horticultural light, perfect for replicating the indirect light of tropical rainforests. Select the length according to the height and spread of your ficus.

• SpectraBULB X20 Horticultural Bulb: ideal for supplementing natural light in a less exposed corner or for targeting a medium-sized ficus.

Lamp-to-plant distance and seasonal settings

• Place the LED lamp At 25–35 cm above the top of the ficus. For a very tall specimen, you may want to install a second side lamp to illuminate the lower part of the foliage.

• Use a timer to ensure 12 to 2 p.m. increase lighting in autumn-winter and slightly reduce the duration in spring when natural light increases.

• Turn the plant a quarter turn during watering so that all sides receive the same amount of light and growth remains balanced.

Watering

A lyre ficus prefers a substrate constantly damp but never soaked. Water generously until water drains from the drainage holes, then empty the saucer. Wait until the The top 2-3 cm of the substrate should be dry. before watering again – usually every 7 to 10 days Use water at room temperature during the growth phase and slightly less in winter. Ideally, water that has been left to stand so that the chlorine evaporates.

Signs of underwatering include drooping leaves, dry edges, and premature leaf drop. Conversely, overwatering causes yellowing leaves, brown spots, and wilting despite moist soil. Adjust watering frequency according to the season and indoor conditions.

Humidity and temperature

This fig tree appreciates a relative humidity of 50–60%. Maintain this rate by:

• placing a humidifier nearby or a tray of damp pebbles under the pot;

• grouping several plants to create a humid microclimate;

• lightly spraying the foliage with the Water Master 2L Electric Sprayer of TerraLED, but not excessively to avoid fungal diseases.

The fiddle-leaf fig thrives in 15°C – 24°C. Avoid drafts, sudden temperature changes, and rooms that are too cold (< 10°C). In summer, keep it away from air conditioners; in winter, protect it from cold windows.

Substrate and repotting

The roots of the Ficus lyrata are susceptible to overwatering. Use a well-draining substrate like the mixture TerraLED Premium Tropical Soil (link below), composed of peat, fibers, and perlite, which ensures both drainage and moisture retention. This plant likes to be slightly root-bound: repot every 1 to 2 years, Only when the roots are growing out of the drainage holes or the plant is becoming unstable. Choose a pot only 2 to 3 cm wider and always ensure it has drainage holes. Water the day before repotting, carefully remove the plant from its pot, trim any dead roots, place it at the same depth in the new pot, fill with fresh potting mix, and water thoroughly. Wait one month before resuming fertilization.

Fertilizers and nutrition

The fiddlehead (Ficus lyrea) is a heavy feeder during its growing season (spring and summer). Use the Hydropassion Pack Organic Vegan Fertilizer Master Grower To provide a balanced fertilizer, dilute to half the recommended dose and fertilize. every 2 to 4 weeks. Excess fertilizer causes burnt edges and stunted growth; insufficient fertilizer results in smaller leaves and overall slowed growth. During autumn and winter, significantly reduce or even stop fertilization to respect dormancy.

Care and sizing

• Cleaning the leaves: Large leaves collect dust, which reduces photosynthesis. Wipe them regularly with a damp cloth and support the leaf to prevent breakage. Avoid using polishing products.

• Size : Remove dead leaves regularly. In spring, prune to balance the shape: cut back overly long stems above a node to encourage branching. This also helps prevent etiolation (stems growing too long towards the light).

• Stable temperature: Keep the plant away from drafts, radiators and air conditioners to prevent leaf drop.

• Regular rotation: Rotate the pot each time you water to ensure symmetrical growth.

Common problems and solutions

Expert advice TerraLED

• Use stable supports To allow the Ficus lyrata to grow taller without wobbling, a discreet stake can support the young plants.

• Clean your LED lamp regularly to maintain its optimal light output. The bars TerraLEDTM PRO are designed to be easily wiped clean.

• Monitor the humidity thanks to a hygrometer; adjust as needed with accessories such as the pebble tray or humidifier.

• Adapt the lighting to the season: Extend the lighting period in winter and adjust the lamp-plant distance if the leaves turn white or curl downwards.

• Use the Water Master 2L sprayer for misting, applying treatments or cleaning leaves easily.
