How to Grow and Care for Philodendron Moonlight, Straight From an Expert

Philodendron moonlight is a tropical hybrid plant known for its glossy, color-changing leaves, which begin vivid neon yellow before darkening to a bright green.

The stems and unopened leaves of this Central and South American forest plant may be a shade of pink. This self-heading philodendron has an upright growth habit, unfurling from a thick central stem rather than on climbing or trailing vines.

As a houseplant, philodendron moonlight prefers evenly moist soil, indirect light, and a warm, humid climate.

Philodendron Moonlight Care

• Give philodendron moonlight bright, indirect light.
• Plant this philodendron in a moist, well-drained potting mix.
• Water philodendron moonlight so that the soil stays evenly moist but not soggy.
• Feed this plant with a balanced liquid houseplant fertilizer during the growing season.

Light

Philodendron moonlight grows best with bright, indirect light, such as in an east-facing window or several feet from a west-facing or south-facing window.

Direct sunlight can burn the leaves and affect plant growth.

Soil

Plant your philodendron moonlight in a loose, rich potting mix that includes peat moss or coconut coir and good drainage.

Add a few handfuls of perlite or pumice to basic houseplant potting mix to increase drainage or purchase pre-made mixes for aroids like philodendrons.

Water

Like other philodendrons, philodendron moonlight prefers relatively moist soil. It's best to check moisture regularly by sticking your finger in the soil rather than watering on a set schedule.

During the growing season, water your plant when the top inch or so of soil has dried out. When growth has slowed down for winter, you can allow the soil to dry out more fully between waterings.

Always check drip trays to keep the plant from sitting in water, which can lead to root rot.

Temperature and Humidity

This jungle plant enjoys humidity, around 60 to 70 percent, but it can handle lower-humidity environments pretty well.

If desired, run a humidifier near your plant to boost moisture in the air, or group it together with other tropical plants to create a more humid microclimate.

Philodendron moonlight prefers temperatures around 65 degrees at night and 80 degrees during the day.

Note that philodendrons can't withstand temperatures of 50 degrees and below without sustaining damage to their foliage.

Fertilizer

Use a balanced liquid houseplant fertilizer diluted to half strength to feed your philodendron moonlight.

Start fertilizing when you see the first new growth in early spring, then fertilize every month until the weather cools and the days shorten in fall. Stop watering until the following spring.

Pruning

It's unnecessary to prune philodendron moonlight, although it's a good idea to cut away dead or damaged leaves as they appear to keep the plant looking healthy.

As self-heading philodendrons can grow relatively wide, you may want to cut back a few leaves here and there to keep the plant more compact.

Propagating Philodendron Moonlight

Philodendron moonlight is relatively easy to propagate by removing offsets, or baby plants, from a mature plant. Propagation tends to be most successful during the spring and summer growing season.

Before you begin, gather small plant pots, potting mix, sterilized pruning shears, and gardening gloves (optional). Here's how to propagate philodendron moonlight.

1. Gently tip the mother plant with offsets attached out of its pot. Examine the base of the plant and identify any offsets you'd like to remove.
2. Use your fingers to loosen the root ball. Gently pull the offset away from the mother plant, making sure that any baby plants have both leaves and roots attached. If necessary, you can cut through any attached roots with your pruners.
3. Fill a small plant pot with fresh potting mix and water well to moisten it.
4. Plant the offset in the pot, patting the soil down around the base of the plant to hold it in place.
5. Repot the mother plant and water it well to reduce transplant shock.
6. Put the baby plant in a warm place with bright, indirect light and keep the soil evenly moist.

Potting and Repotting Philodendron Moonlight

You'll know it's time to repot your philodendron moonlight when you see roots growing out of the bottom of the pot or covering the top of the soil.

The plant may show stunted growth or a dull appearance when severely rootbound. Remove the pot, loosen the root ball, and repot with fresh soil in a container that's one to two inches larger in diameter than the original pot.

Avoid terracotta pots, which can wick away moisture too quickly for philodendrons. Always use a container with drainage holes in the bottom.

Common Pests & Plant Diseases

Philodendron moonlight can be affected by common houseplant pests like scale, aphids, mealybugs, and spider mites.

It can also suffer from diseases such as bacterial leaf spot, which presents as reddish-brown spots with yellow edges or large, tan splotches.

Common Problems With Philodendron Moonlight

Leaves Turning Yellow

Yellowing leaves are a common sign that your plant is getting too much water. Check the soil, and if it feels soggy, cut back on watering. Resume watering when the soil has completely dried out.

Curling Leaves

Leaf tips that curl down and turn brown can indicate that your philodendron is getting too much fertilizer.

Flush the soil with water to leach out excess nutrients and fertilize less often going forward. If using liquid fertilizer, make sure it's diluted to half-strength or quarter-strength before application.

If you use slow-release fertilizer granules, avoid leaching the soil and repot the plant instead.

New Leaves Are Dark Green

If your philodendron moonlight's leaves aren't unfurling with that signature bright, neon green color, there's a good chance your plant isn't getting enough light. Move your plant closer to a light source, ensuring it's not getting direct sunlight.
