Philodendron Moonlight: Complete Lime Philodendrons Care Guide

Philodendron Moonlight will light up dim corners of your home and garden with an almost magical lime hue. This easy-to-care-for philodendron features bright leaves, which gradually become darker in color as they mature. The unusual color makes them ideally suited to contrast with other plants in the garden or to offset any dark backdrop or feature wall in your home. The Moonlight is a cheerful addition to any setting and may quickly become your favorite houseplant.

Philodendron Moonlight is an easy to care for hybrid variety philodendron. The plant has distinctive yellow-lime colored leaves that offer a dash of brightness to any surroundings. This tropical plant is low-growing and occasionally produces fleshy white flowers that have a deep pink center.

Although Moonlight is one of the most forgiving members of the Philodendron family in terms of care, there are still some considerations to keep in mind.  Knowing how to care for this bright-leaved wonder keep it looking its best for many years to come.

In favorable conditions, Moonlight can become quite large and be an impressive feature. These plants are usually shrub-like and low growing, but large specimens can spread their glorious, almost florescent leaves as high as 24 inches and equally wide. To reach this size, they need basic care and will reward you with bright, healthy growth.

Like all philodendrons, the leaves of Moonlight are toxic to humans and pets, which is something to keep in mind when you are selecting plants for your home. However, this family of plants is also well-known as effective air cleaning plants which filter airborne toxins, and Moonlight is no exception. The large bright plant is very popular and readily available at most nurseries and plant supply stores.

Philodendron Moonlight is well known as an easy to care for plant. To keep your Moonlight in peak condition, there are a few elements that you should keep in mind:

  • Lighting
  • Watering
  • Soil
  • Temperature
  • Humidity
  • Fertilizing
  • Pests

Each of these is important and will affect the overall health of your plant.

Philodendron Moonlight Light Requirements

Philodendron Moonlight loves sunlight, so long as it isn’t too harsh and direct. The plant thrives in bright areas where the sun’s rays are filtered or very gentle, such as early morning.  A good position for this plant is near east-facing windows. If you would like to keep your Moonlight in a sunny place, be sure to screen the plant from the intense midday sun.

Like all philodendrons, the large leaves can burn or become an unhealthy shade of yellow if they receive too much direct sunlight. On the other hand, if the Moonlight environment is not light enough, the stems tend to become leggy, with smaller leaves.

Display your lime-green philodendron in a spot where it will receive moderate lighting. A few hours of bright indirect sunlight will recharge the luminescent color of your plants’ leaves and keep them bright and healthy-looking.

Watering Your Philodendron Moonlight

It’s often difficult to know how often to water your house plants. We want them to thrive, so overwatering often results because we don’t want our plants to dry out. However, philodendron plants are far more likely to suffer as a result of overwatering than the opposite.

The soil of the Moonlight should be kept moist but never soaked. Excess water should immediately drain through the soil and out of the pot away from the roots.  Before you water, check that the top inch of the soil is completely dry. You can do this by sticking the tip of your index finger into the ground. If you feel moisture just below the surface, hold off with the watering for a few days.

Allow the top 2 inches of the soil to dry out completely before you water the Moonlight. Overwatering your plant may result in root rot which is almost always fatal. Incorrect watering can cause the leaves of the plant to become droopy. Fortunately, the Moonlight is hardy, and if you quickly correct the watering schedule, it should recover.

Philodendron Moonlight Soil Requirements

The Moonlight requires a fast-draining potting medium that provides enough nutrients and adequate aeration. This may seem like a really tall order, but it can easily be achieved by adding perlite, peat moss, or vermiculite to regular potting soil. These plants do best in soil that is high in organic matter.

While a well-aerated, fast-draining potting soil works well, Moonlight can also be grown in soilless mediums such as peat-perlite.  Sphagnum peat moss is an excellent option for Philodendron Moonlight because it is loaded with organic nutrients while offering good aeration.

The soil must never become soggy, and drainage holes at the bottom of the pot must allow excess water to run through without building up around the roots.

Philodendron Moonlight Temperature Requirements

Philodendrons are tropical plants and are therefore not tolerant of frost or cold. They must never be exposed to temperatures below 55F. This needs to be considered if you are thinking about keeping the Moonlight outside. 

The inside temperature range of most homes is suitable for Moonlight to thrive. The optimal range is between 65F and 80F, but slight variations above this are tolerated.

Philodendron Moonlight Humidity

Tropical plants are sensitive to both temperature and humidity. Although Philodendron Moonlight prefers an environment where the humidity is around 70%, it can tolerate average room humidity.

Keeping the pot on a pebble tray is an attractive way of increasing the overall humidity around the plant without causing overwatering or soaking the roots.  Try to place them in areas of the house where they will not be exposed to direct heat sources like vents which can dry out the leaves.

If the environment where you keep your Moonlight is extremely dry, the plant will benefit from a humidifier. You can also occasionally mist the plant, but be sure not to use cold water, which will shock the leaves and cause discoloration.

Fertilizing Your Philodendron Moonlight

Philodendrons often don’t require a lot of fertilizing, but it can help to give them a bit of a boost during the growing season. Signs like small leaf size, pale new leaves, and slow growth are indicators that the Moonlight will benefit from adding some extra nutrients.

An organic houseplant liquid fertilizer for foliage plants can be given monthly during the spring and summer months. Just be careful to follow the dilution instructions on the fertilizer label carefully to avoid fertilizer burn. During the cooler months, you can fertilize less frequently.

Philodendron Moonlight Diseases and Pests

Besides their attractive appearance, one of the reasons that Philodendrons are popular houseplants is because they are not prone to plant insects. Pests like mealybugs, aphids, thrips, and spider mites can easily be treated with neem oil or plant insecticide.

The biggest threat to the health of your beautiful Moonlight is root rot from overwatering or the soil not draining adequately. If your soil is light and free draining and the drainage holes on your pot are open, this should not occur. Be sure to check that the water-catching saucer under the pot has not filled with water which might cause moisture to build up around the plant’s roots.

If root rot does set it to your Philodendron Moonlight, immediately repot the plant. Remove as much of the soggy damaged roots as possible and repot in clean, free-draining soil. There is no guarantee of recovery once the plant is affected, but providing a clean, fresh potting medium is the only way that you may be able to save the plant.

Propagation Of Philodendron Moonlight

Philodendron Moonlight is easily propagated, so once you have a healthy established plant, you can start multiplying from it. The two most common methods used are stem cuttings and bulb division, but the latter method is quite invasive and should only be undertaken when moving the plant to a bigger pot.

Stem cuttings can be taken from the Moonlight many times over the lifetime of the plant. The best time to grow new plants from stems is during spring and summer.  

Slice a healthy stem off cleanly where it meets the plant’s stalk and place it in a vase of water. You will have to be patient because growth may only be observed after a few weeks. When small roots finally begin to appear, wait until they are at least 2 inches long before planting. Ensure that for the first few weeks, until the roots are established, the soil remains moist to touch at all times.


The Moonlight is a very manageable and hardy pot plant. Its unusual lime color is eye-catching and makes it an excellent feature. Keeping this hybrid philodendron healthy and looking impressive is not difficult. Moonlight is a good starting option for anyone who loves the bold leaves of philodendrons but is not yet experienced in caring for them.
