Key facts

Detailed care guide

The split-leaf philodendron is a striking large foliage plant with broad, deeply lobed leaves. It's easy to grow indoors, which is why so many people love it.

Watering

It's best to water once the top 2–3cm of soil has dried out. Overwatering can turn the leaves yellow or mushy, so be careful. Watering about once every 7 days is generally appropriate.

Light

The split-leaf philodendron likes bright indirect light or partial shade. If light is lacking, the stems can grow long and the leaves may become weak. Avoid strong direct sunlight, as it can cause the leaf tips to scorch.

Humidity

It prefers average to high humidity. If indoor humidity is too low and the leaf tips start to dry out, mist occasionally or place a water tray nearby to help.

Temperature

It grows healthy between 16–28°C. Growth can slow if the temperature is too low or too high, so maintain a suitable temperature.

A common first-timer mistake

The most common mistake is watering too often. Always make sure the soil surface has dried out enough before watering.

If you have pets

The split-leaf philodendron is toxic to pets. Keep it somewhere dogs or cats can't chew on the leaves or stems, and contact a vet right away if you suspect your pet has eaten some.

Care by Season

The split-leaf philodendron grows vigorously in spring and summer, so fertilizing once a month during this period is a good idea. Don't forget to keep up with watering and light during this time too. In fall and winter, growth slows down, so cut back on watering and fertilizing.

Common Problems and Fixes

Overwatering causes the leaves to turn yellow or mushy, while too little water causes the leaf tips to turn brown. If light is too low, the stems grow thin and long, so a bright window is ideal. If dust builds up on the leaves, wipe them with a damp cloth to keep them clean.

Repotting and Propagation

It's important to plant it in a well-draining soil mix. Repot when the roots are crowded or growth seems to have stalled. It can be propagated by division when growth is vigorous.

Who It's Great For

It's a great choice for anyone who loves broad leaves and a distinctive look, or who has plenty of indoor space. It's a good option if you're looking for a low-maintenance plant that grows well without much fuss. It's also a great recommendation for anyone who wants to feel a bit more greenery in a busy daily life.
