Philodendron selloum is a big-leaf beauty in the Aroid clan. When included in an indoor space it screams lush jungle vibes. In this post, we will look at the care requirements for this tropical beauty.

Philodendron selloum which is technically Thaumatophyllum bipinnatifidum, however, we still call it P. selloum. Similar to Twitter which is X, but we still call it Twitter.

Below you’ll find a detailed care guide for this Philodendron :

Light

This plant loves lots of light, and in my humble opinion that is the key to getting it to reach massive proportions. You want to expose your plant to bright indirect light with some morning sunlight if the plant is acclimated to it. I’ve found that light from above works well for these plants as they tend to stretch out sideways toward the light source. This gives the plant a splayed-out appearance whereas light from above will help to keep the plant growing compact and lure the leaves upright.

Top Tip : If you don't have light coming in from above, then keep your Philodendron on the floor so that it grows up toward the light and helps the plant stay compact.

This is not a plant for medium and low light as it will result in etiolation, which is when the petioles, or stems elongate and become spindly trying to get at the light.

Watering

Philodendrons all like to be moist, but not too wet. They can withstand periods of drought, pretty well which makes them ideal for the forgetful plant parent.

In general, I water my Philodendron selloum once a week. I like to give it a thorough soaking and then I let it dry out a bit before repeating the process.

Humidity

These Philodendrons are fine in normal household humidity and that's a relief! As anyone who has tried to grow Philodendron Verrucosum in the house will know.

Fertilizer

I fertilize my philodendron with a balanced houseplant fertilizer, if you are going to up the nitrogen make sure that there is additional calcium to help the structure of the plant as high nitrogen on its own can sometimes result in floppy weak growth.

Soil

A well-draining loamy mix will work well, with lots of bark and perlite to give that much-needed drainage. I’ll include a video on how you can mix up the ideal indoor potting medium. This recipe is ideal for all aroids are it provides essential drainage and oxygen for the roots.

Pests

Two pests in particular love to visit Philodendron selloum from time to time. One is scale and the other one is spider mites. Luckily these can both be easily snuffed out with neem oil, which is a natural non-chemical pesticide spray.

I hope that you have enjoyed this post!
