The Moonlit Cypress (Cupressus macrocarpa 'Goldcrest') is a stunning evergreen houseplant that’s adored for its elegant, feathery foliage in soft golden-green hues. Its subtle citrus scent adds an extra layer of charm, making it a favorite for indoor gardening enthusiasts.
Commonly referred to as the Lemon Cypress, the Moonlit Cypress brings year-round beauty to any space, whether it’s used as a decorative focal point or a festive holiday accent. Though low-maintenance, this plant thrives when given proper care and attention. Here’s your ultimate guide to growing and maintaining a healthy Moonlit Cypress indoors.
The Moonlit Cypress loves bright light and thrives in a sunny spot. Place it near a south- or west-facing window where it can receive 4–6 hours of bright, indirect sunlight daily. While it can tolerate some direct sunlight, too much harsh light can cause its delicate foliage to dry out or scorch.
If you don’t have a bright enough location, supplement the light with a grow light to keep your Moonlit Cypress vibrant and healthy.
Tip: Rotate the plant every few weeks to ensure even growth and prevent it from leaning toward the light source.
The Moonlit Cypress prefers moderately moist soil, so it’s important to strike a balance between underwatering and overwatering. Check the top inch of soil regularly, and water when it feels dry to the touch. Avoid letting the soil completely dry out, but also ensure that the roots don’t sit in water, as this can lead to root rot. When watering into a pot without drainage holes, be sure to discard any excess watering sitting at the bottom of your pot to prevent root rot or pests.
In warmer months, you may need to water more frequently.
During the plant’s dormant period in winter, reduce watering slightly, allowing the soil to dry out a bit more between waterings.
Tip: Use a pot with drainage holes to prevent waterlogging, and empty the saucer after watering to avoid stagnant water.
This plant thrives in cool, moderate temperatures, ideally between 50°F and 70°F (10°C to 21°C). It doesn’t tolerate extreme heat or cold, so keep it away from drafty windows, heaters, or air conditioning vents.
Humidity is also crucial for the Moonlit Cypress. While it can adapt to average indoor humidity, it prefers a slightly humid environment. If your home tends to be dry, especially in winter, consider misting the plant occasionally or placing a small humidifier nearby.
The Moonlit Cypress grows best in well-draining soil. Use a standard potting mix combined with sand or perlite to enhance drainage.
Feed your Moonlit Cypress with a balanced, water-soluble fertilizer every 4–6 weeks during the growing season (spring through early fall). Reduce or stop fertilizing during the winter months when the plant is less active.
Tip: Dilute the fertilizer to half-strength to avoid overfeeding, which can damage the plant’s roots.
The Moonlit Cypress has a naturally compact, conical shape that requires minimal pruning. However, light pruning can help maintain its shape and encourage fuller growth. Trim any dead, damaged, or overgrown branches using clean, sharp scissors or pruning shears.
If you’re using the plant as a decorative feature during the holidays, you can give it a gentle trim to fit your desired look, but avoid cutting back into old wood, as this can slow regrowth.
Repot your Moonlit Cypress every 2–3 years or when it outgrows its container. Look for signs like roots circling the bottom of the pot or growth slowing significantly. Choose a pot that’s 1–2 inches larger in diameter, and ensure it has drainage holes.
Spring is the best time for repotting, as the plant is entering its active growth phase.
Propagating the Moonlit Cypress can be a rewarding process, though it requires patience. The most effective method is through semi-hardwood cuttings, taken in late spring or early summer. To propagate, select a healthy branch and cut a 4–6 inch segment just below a node. Remove the lower leaves from the cutting, leaving a few at the top, and dip the cut end into rooting hormone to encourage faster root development.
Plant the cutting in a small pot filled with a well-draining mix of sand and peat moss, keeping the soil moist but not soggy. Cover the cutting with a plastic bag or dome to maintain humidity, and place the pot in a warm, bright location out of direct sunlight. Roots typically develop within 6–8 weeks.
Once the cutting has rooted, it can be transplanted into a larger pot with regular soil. While propagation success rates may vary, proper care and patience can yield a healthy new Moonlit Cypress plant.
Drying or Browning Tips: This can occur due to low humidity or underwatering. Increase the humidity around the plant and check your watering routine.
Yellowing Foliage: Overwatering is a common culprit. Ensure the soil isn’t waterlogged and adjust your watering schedule.
Pests: Although relatively pest-resistant, spider mites or scale insects can occasionally appear. Treat any infestations with insecticidal soap or neem oil, and isolate the plant if necessary.
Unfortunately, the Moonlit Cypress is not safe for pets. If ingested, it can cause gastrointestinal upset in cats and dogs. To keep your furry friends safe, place the plant in a location that’s out of their reach, or consider pet-safe alternatives for your indoor greenery.
The Moonlit Cypress’s soft, golden-green foliage makes it a standout decorative piece in any home. It’s especially popular during the holiday season when it can be adorned with tiny ornaments, string lights, or a small star on top as a tabletop Christmas tree. Outside of the holidays, its lush, vibrant appearance makes it a perfect accent for minimalist or rustic interiors.
