Philodendron Squamiferum Care Guide: 7 Tips for a Healthy Plant

Philodendrons are an increasingly popular choice for houseplant enthusiasts and gardeners. And it is easy to see why. This large plant family has seemingly endless options to choose from. The only challenge is finding a nursery that carries the species you love. As you’ve done your research, you may have discovered an intriguing species called Philodendron squamiferum. This interesting flowering plant brings eye-catching intrigue to any room. But the best part is that it is easy to care for, making it beginner-friendly. We have collected all the tips and tricks you need to care for your new philodendron (should you decide to purchase it). Keep reading to discover 7 tips for a healthy plant.

What is a Philodendron Squamiferum?

Philodendron squamiferum is a stunning and fascinating plant. It showcases a botanical feature called pubescence with its red fuzzy stems, which is where it gets its name. This philodendron is commonly called red bristle philodendron and is native to French Guiana, Suriname, and Brazil. So, as you can imagine, it is a tropical plant that prefers a warm, humid environment.

This species is a vining perennial, which can grow 3 to 10 feet (1 to 3 meters) by the time it reaches maturity. Since it has a climbing habit, placing it near a trellis or wall will help it reach its full height. The red bristle philodendron is a member of the Araceae family, with 140 genera and over 4,000 species. Unfortunately, P. squamiferum is one of the philodendrons that is toxic to pets and humans. So, if you have children or animals running around, it is safest to keep this plant out of reach.

The lovely red bristle philodendron features dark green leaves that each grow up to 18 inches long! The foliage is also textured, giving the plant even more intrigue. 

#1 – Enough Indirect Light

Red bristle philodendrons are fairly forgiving when it comes to their light requirements. This species can tolerate either partial shade or full sun. So, you have a little extra flexibility with where to place your new flowering plant. The only caveat is that you will need to keep it inside much of the year if you don’t live in USDA Hardiness Zones 9 to 11. This narrow environment is where the philodendron is happiest and will live for the longest period of time. However, indoors is also the optimal choice for its light needs. The red bristle philodendron does best in dappled shade or partial and indirect light. However, the light it does receive should be bright.

#2 – Adequate Watering

One of the most common problems plaguing all philodendron plants is the tendency many of us have to overwater. It is a common misconception since these are tropical plants. And while they need ample water, there is such a thing as too much. Philodendrons don’t like wet “legs,” or roots. Adding too much water to the soil means the plant can’t soak it all up. That persistent presence of water may ultimately allow root rot to set in, which will kill your red bristle plant.

All you need to do to avoid this situation is check the soil. Stick your finger in until the soil is level with your knuckle. If it feels dry at the tip of your finger, your plant can use some more water. However, the opposite is also true. If the soil still feels damp, your plant won’t need more water yet.

Another factor to keep in mind before watering is the time of year. These plants require different levels of water throughout the seasons. They essentially go dormant in the fall and winter, growing little to none. That means your philodendron needs even less water. Allow the soil to dry out almost entirely before watering again.

Improper water (whether that’s over or under) will show stress in the plant. You may spot some yellow or drying leaves. However, there can also be several other underlying factors. Take some time to watch your process more closely, documenting all your steps. Make adjustments to the watering schedule when needed.

#3 – Proper Temperature and Humidity Levels

Since Philodendron squamiferum is tropical, it needs plenty of heat and humidity. The first is relatively easy to take care of. Your philodendron will remain happy as long as you maintain an internal temperature of 65 to 85 degrees Fahrenheit (18 to 26 degrees Celsius) in your home. But large temperature fluctuations can also damage your plant. Keep the pot away from heating vents and AC units, where they are more likely to encounter harmful drafts. 

Where many first-time philodendron owners run into trouble is trying to maintain an adequate humidity level. Thankfully, that process is much easier than one may think. To achieve (and maintain) the preferred humidity level of 60 to 70%, consider taking one of the following steps:

• Add a pebble tray under the pot and keep it filled with water.
• Install a humidifier close to all your tropical plants.
• Place your philodendron in a more humid space like the bathroom or laundry room.
• Mist the foliage occasionally.

#4 – High-Quality Soil

Red bristle philodendrons thrive in high-quality potting soil. They gain their nutrients and water needs through their root system. So, the planting medium you pot them in should be loose enough for their roots to stretch out. If you can find a pre-made mix that is loose enough, feel free to give it a try. Alternatively, you can make your own blend with standard potting soil, perlite, and other amendments to loosen up the soil. 

#5 – Avoid Over Fertilizing

Philodendron squamiferum doesn’t grow fast, so it isn’t a heavy feeder. That’s good news for you! It means this plant is slightly more cost-effective than others since you don’t need to keep as much fertilizer on hand. When you do add fertilizer (once or twice a month during the growing season), opt for a slow-release or water-soluble option. 

When the peak growing season is over, you can cease fertilizing the plant.

#6 – Repot When Needed

Don’t be fooled by the slow-growing nature of Philodendron squamiferum. It still has an aggressive root system that may take over the pot before you think the plant is ready. Watch for telltale signs like roots growing out of the drainage holes or encircling the pot’s interior.

When you are ready to repot, stick to containers only one or two sizes larger. Anything bigger than that typically leads to overwatering, resulting in root rot.

#7 – Watch for Pests and Diseases

Red bristle philodendrons are relatively happy plants free of most pest and disease issues. But that doesn’t mean you are entirely in the clear. These tropical plants can easily suffer from root rot, as we discussed above. However, they are also susceptible to underwatering. One sign to watch for is yellowing leaves. They are indicative of stress somewhere on the plant, usually related to its watering schedule.

Over and underwatering your Philodendron squamiferum can also attract pests. Spider mites show up when the soil gets too dry and fungus gnats arrive when there is too much moisture present.

Another thing to watch for isn’t technically a disease but is something to be aware of. If the leaves of your philodendron start to turn brown, your plant needs additional humidity. Take one of the steps listed above to boost the overall humidity level and prune any dead leaves. Your plant will likely recover fully if you catch this problem in time.
