Hoya lacunosa ‘Moonlight’ is a popular cultivar known for its appealing appearance and easy care. This plant features distinctive ovate leaves with pointed tips, displaying a pale silvery-green hue and luminous sheen. Its compact, trailing growth habit makes it suitable for hanging baskets or shelves, adding an elegant display to indoor spaces. It also produces fragrant, cinnamon-scented flowers, contributing to its popularity among plant enthusiasts.
Caring for Hoya Lacunosa Moonlight
Light
Hoya lacunosa ‘Moonlight’ thrives in bright, indirect light, mimicking its natural habitat as an epiphyte under a tree canopy. An east or west-facing window is suitable, tolerating some direct morning sun. However, harsh afternoon sunlight can scorch leaves or cause a pinkish blush. Insufficient light limits flowering. For artificial lighting, 12 to 14 hours daily encourages healthy growth and blooming.
Watering
Hoya lacunosa ‘Moonlight’ prefers its soil to dry out between waterings. Allow the top one to two inches of soil to dry before watering again. Its thinner leaves store less water, potentially requiring more frequent watering than other Hoyas. Overwatering causes root rot, so ensure proper drainage. Reduce watering in cooler months as growth slows.
Humidity and Temperature
Hoya lacunosa ‘Moonlight’ benefits from moderate to high humidity, ideally 60% or more, for faster growth and abundant blooms. While it adapts to average indoor humidity (40-50%), higher levels improve vitality. Boost humidity with a humidifier or pebble tray. The plant prefers 65–85°F (18–29°C). Protect from cold drafts and temperatures below 55°F (13°C).
Soil Mix
An airy, well-draining potting mix is suitable for Hoya lacunosa ‘Moonlight’ due to its epiphytic nature. A good blend prevents waterlogging and provides aeration. Common ingredients include orchid bark, perlite, and coco coir. Horticultural charcoal and worm castings can also be added for drainage and nutrients. This mimics natural conditions, promoting healthy root development.
Fertilizing
During its active growing season (spring through early fall), Hoya lacunosa ‘Moonlight’ benefits from regular feeding. Apply a balanced liquid houseplant fertilizer, diluted to half strength, every four to six weeks. A bloom-boosting fertilizer with higher phosphorus can encourage flowering. Reduce or stop fertilizing in winter when growth slows. Apply to slightly moist soil to prevent root burn.
Pruning and Support
Hoya lacunosa ‘Moonlight’ requires minimal pruning due to its compact, trailing habit. Prune to shape, remove leggy vines, or encourage bushier growth. Use clean, sharp scissors for precise cuts. Avoid cutting peduncles (flower nubs), as new blooms emerge from these repeatedly. While naturally trailing, it can be trained to climb.
Repotting
Hoya lacunosa ‘Moonlight’ prefers to be somewhat root-bound, which encourages blooming. Repot every two to three years, or when significantly root-bound (roots circling or growing out of drainage holes). Repot in spring or summer during active growth. Choose a pot only one size larger to avoid over-potting. Gently transfer without excessively disturbing roots.
Propagating Hoya Lacunosa Moonlight
Propagating Hoya lacunosa ‘Moonlight’ is commonly achieved through stem cuttings. This creates new plants from a section of the parent. Select a healthy stem, four to six inches long, with at least two nodes (where leaves emerge). Make a clean cut just below a node using sharp, sterilized tools. Remove leaves from the lowest node to prevent rotting in the rooting medium.
Cuttings can be rooted in water (change water every few days), moist sphagnum moss, or a well-draining soil mix. Keep moss or soil consistently moist, not soggy. Adequate humidity, via a plastic bag or dome, enhances root development. Rooting takes several weeks to months, depending on conditions. Spring and summer are best for propagation during active growth.
Common Problems and Solutions
Yellowing leaves can signal overwatering or underwatering. Consistently wet soil causes root rot, leading to yellow, mushy leaves. Conversely, prolonged dryness causes thinner leaves to yellow and wilt. Adjust watering to allow soil to dry between waterings. Nutrient deficiencies also cause yellowing; a balanced fertilizer during the growing season can help.
A lack of blooms is a frequent concern for Hoya owners. This is often linked to insufficient light, as bright, indirect light is necessary. The plant may also not bloom if not somewhat root-bound, as a snug pot encourages flowering. Adequate phosphorus in fertilizer during the blooming season also stimulates flower development.
Hoya lacunosa ‘Moonlight’ can encounter common houseplant pests such as mealybugs, spider mites, and scale insects. Mealybugs appear as small, white, fuzzy insects. Spider mites are tiny, often creating fine webbing. Scale insects are small, oval-shaped, and adhere to stems and leaves. If pests are detected, isolate the plant to prevent spread. Treat affected areas by wiping them with rubbing alcohol, or applying insecticidal soap or a neem oil solution. Consistent inspection of the plant’s leaves aids in early detection and treatment.
