Philodendron warscewiczii

These plants like a moderate amount of soil moisture. Water whenever the top inch of soil has dried out. Both overwatering and underwatering can cause the leaves to droop, so gauge when it’s time to water by the soil dryness and not necessarily the leaves. Philodendrons don’t do well sitting in soggy soil, as this can lead to root rot. The non-climbing varieties tend to have a little more drought tolerance than the vining species.

These plants should not be exposed to temperatures below 55 degrees Fahrenheit. Indoors, protect them from cool drafts, such as those from an air-conditioning vent. These plants do like humidity, so if you live in a dry climate you might have to boost humidity around your philodendron. To do so, you can mist the plant every few days with water from a spray bottle. You also can place the container on a tray of pebbles filled with water, ensuring that the bottom of the container isn't touching the water, which can lead to root rot.

Use a balanced liquid fertilizer monthly on your plant in the spring and summer. Then, reduce feeding to every six to eight weeks in the fall and winter. If your plant isn’t getting enough food, its growth will be slower than normal and its leaves might appear smaller than usual.

Philodendron leaves and stems are high in calcium oxalate. This can be toxic to both people and animals when eaten.
