To clear your doubts, here is a detailed care guide.

Philodendron Squamicaule Water Requirements

Philodendron Squamicaule is a water-loving plant, but it does not like soggy soil. You should water it regularly because underwatering can kill it in no time. As soon as the top 3 centimeters of its soil gets dry, water this plant. In the growing season, you will have to water it every 6 to 7 days. The soil takes time to dry in winters, so one watering is enough for about ten days or more. On the other hand, this plant needs more watering in the summers.

This plant should be watered thoroughly by holding its pot under a sink. Let the water run into its soil until its excess starts to drain from the drainage hole.

Soil Requirements

The roots are the support system of a plant, and these roots breathe through the soil. It is why the growing medium of the plant must be light and airy to allow maximum oxygen flow to encourage healthy growth of the roots.

Philodendron Squamicaule also prefers a well-aerated, perfectly draining, lightweight potting mix with air pouches. A peat-based potting mix is ideal for this plant. It is because peat moss increases the moisture-retaining ability of the plant and also its aeration. A slightly acidic to neutral potting mix with a pH of 6.0-7.0 is considered the best for this plant.

Philodendron Squamicaule Sunlight

This gorgeous tropical species thrive in bright, indirect sunlight. Low light exposure turns its leaves pale and dull. So discoloration of the leaves is a sign that the plant is not receiving ample light exposure.

Too much sunlight or the direct sun is also not good. Direct sun is scorching and too intense for the delicate leaves of this plant. Direct sunlight can even burn the leaves. So you should avoid placing this plant outdoors without a shade cloth.

Temperature Tolerance

Almost all tropical plants prefer to grow in warmer temperatures. These tropical plants make excellent house plants because their optimal temperature range is the same as the average indoor temperature. Similarly, Philodendron Squamicaule grows optimally in a warmer temperature, ranging from 25°C to 27°C.

As this plant is not frost-tolerant, it should be kept in a warmer spot in winters, such as a greenhouse or terrarium. It would be best this plant is placed in a corner where it faces lesser temperature fluctuations throughout the year.


If you have grown a tropical rainforest plant before, you might already know that such plants need high humidity to thrive. The Philodendron Squamicaule type also needs high humidity to maintain its leaves’ beautiful colors and freshness. Relative humidity of 70% is required to be set for this Philo.

Misting is a great way to increase the moisture level around a plant. However, you should remember that the leaves need to be wiped dry after a good misting. Moist leaves attract more pests than dried-out ones.


Like every other living being, plants also need nutrients to survive. These nutrients are supplied to the plants through fertilizers. For this Philodendron species, a liquid fertilizer does the best job. This fertilizer must have a balanced amount of nitrogen, phosphorus, and potassium. In the growing season, this plant should be fertilized every month. But, in winters and fall, it needs light feeding, every 6-8 weeks only.

Overfertilization does more harm than good. All the excessive fertilizer builds upon the surface of the soil and hardens up. It stops the roots from absorbing enough water or nutrients. This leads to the death of the plant.

Grooming and Pruning

Pruning a plant has two reasons: to limit the plant size and to remove damaged leaves. A plant usually drops all the old leaves by itself. But if it does not do so, it should be you who cut them down. Yearly grooming and pruning also avoid any leggy appearance of the foliage. And not only this, but pruning also encourages more growth. It is why pruning is done at the beginning of the growing season.
