Philodendron Moonlight guide

An indoor gardener with green thumbs should be thinking most about watering and lighting. Humidity and temperature are important if you wish for huge leaves. The moonlight philodendron is easy-to-grow if leaf size isn’t important. Indoor air is fine for this philodendron. Make sure to give bright light, to encourage the plant to grow.

We will go through all the most important facts and knowledge you NEED to know.

Optimal lighting for Moonlight Philodendron

The moonlight philodendron thrives best in indirect sunlight. Too much sunlight can easily burn the leaves. Excessive sun can also dry out your plant. Sunlight will make water evaporate faster than it can be replaced.

Place the moonlight philodendron in the east or north-facing window. If you have to place it in west or south-facing window, put it a couple of feet from the window.

Too little light will cause the leaves to grow smaller and slower. To be on the safe side, lean towards moderate, instead of excessive sunlight.

Water requirements for Moonlight Philodendron

Moonlight philodendrons prefer to dry out between waterings. Let the top two inches of soil dry out before watering again. Make sure to water the plant throughout. Water enough for excess water to drain out of the pot.

In fall and winter, you need to water less. During spring and summer, water more often. Higher temperatures and sunlight will dry out your plant faster.

It is important to avoid overwatering. Watering too frequently can cause root rot in the moonlight philodendron. A good way to avoid root rot is to have soil with good drainage.

Potting soil / Substrate

The best soil for philodendrons is one with good aeration and water retention. An organic mix with perlite is perfect for philodendron soil.

Make a mix of sphagnum peat moss and coco coir. 

All good potting soil should have perlite. It increases drainage and water retention. A good gardener chooses the right pot for each plant. The pots should not have a saucer/bottom plate. A saucer will make water accumulate under the pot. Too much water near the roots for an extended time WILL cause root rot. If you use a saucer, make sure to clean it and empty water from it.

The pot must have draining holes to drain excess water. Make sure you do not have rocks near the bottom of your soil. Rocks can block water from leaving the soil, making the bottom muddy. A potted houseplant should never be dying from root rot. Correct potting mix is super important for your plants to thrive.

Best Temperature

The moonlight philodendron is sourced from the rainforests of South America. It does not like cold weather at all.  Temperatures of 65° to 79° degrees Fahrenheit are perfect. Keep in mind that the plant does not like big temperature swings. Try to keep temperatures above 55° F.

Keep the plant inside in the winter. You can keep it outside during the summer as long as temperatures and sunlight aren’t excessive.


Normal room humidity is good enough for the moonlight philodendron. But the plant will benefit from high humidity and misting. For optimal growth, keep humidity above 65%. Under this threshold, the leaves will grow smaller.

If you have a greenhouse available, it would be a good option, as long as it does not get much sunlight. A gardener with indoor plants should not worry much about humidity.


Feed the plant fertilizer once a month during spring and summer. Use a regular liquid fertilizer. The solution should be diluted ⅓. During fall and winter, use fertilizer every 3 months.

Coffee ground is a good booster for slow glowing philodendrons. It contains minerals and nutrients mimicking the moonlight’s native soil. You should add coffee ground an inch under the topsoil. Keep it as a rare treat for slow-growing philodendrons.

Pruning and maintenance

Philodendron moonlight is an easy plant to maintain according to most. Pruning is an art form, subject to the beauty of the beholder. Remove bad stems and branches with a cleaned and sterile pruner/cutter. Lazy/leggy stems should be cut, as the plant’s energy should be used in more productive areas.

Make sure never to remove too many leaves, as it will hinder photosynthesis.

Clean the leaves by misting. The water will remove dirt and dust from its leaves.
