The philodendron mexicanum is a climbing philodendron with long arrow-head shaped leaves that start off light green in color and then harden off to a darker green as they get older. It’s a really nice philodendron if you like these long leaved varieties.

Philodendron Mexicanum Light Needs

Give your plant plenty of indirect sunlight, but no direct. They will grow best in bright light but must not get direct sun, I would put them to the side of a south facing window, so it is really bright but avoid direct scorching sun.

How Often to Water

To ensure you do not over or underwater your plant you should check the soil every week, and water it as long as it is mostly dry.

Tip: would be cautious when watering this plant, they must not sit in wet soil. As they can get root easily. So it is important to only water them when most of the soil is dry. I also make sure I tip out any water that is in the tray under the plant.


Feed your plant once a month in the spring and summer months a balanced plant feed.


A well draining soil is essential, make sure it is better draining than a standard compost. Add perlite if you can, so that it make up about a fifth of the soil mix. You can go further and make a mix of equal pat perlite, orchid bark and potting compost for a really airy and chunky mix, I use this for most of my plants.

How To Propagate Philodendron Mexicanum

For best results, use sphagnum moss to propagate your philodendron mexicanum. Take a cutting with one leaf and node and put it in moist sphagnum moss. It will root in a month or two, just keep it moist and humid with some indirect sun. When it starts to grow new leaves and has a good root system you can pot it up in a new pot.

When To Repot A Philodendron Mexicanum

Repot this plant every spring, and make sure it has plenty of room to grow in the forthcoming growing months.

Tip: I check all my plants at Easter time and look at the roots, then pot them up a size if they are starting to get crowded. This way they will have room to grow over warmer growing months.


60% humidity is ideal for a philodendron mexicanum. I would get a humidity meter to monitor max and min levels so you can keep an eye on it. These plants thrive in decent humidity.

Philodendron Mexicanum Temperature

18-27°C (64-81°F) is a great range for your plant during the day, so it will be fine in most homes, as long as you keep it out of drafts in winter. Try to keep it above 10°C (50°F) at night or in the winter.
