Philodendron domesticum prefers bright, indirect light, but can also tolerate lower light levels. Avoid direct sunlight, as it can scorch the leaves.

Light

Water the plant thoroughly and allow the top inch of soil to dry out before watering again. Overwatering can lead to root rot, so it's important to ensure that the soil is not constantly wet.

Watering

Humidity

Philodendron domesticum thrives in a humid environment. Mist the plant regularly or place a humidifier nearby to increase humidity levels.

Temperature 

Keep the plant in a warm and humid environment, with temperatures ranging between 65-80°F (18-27°C). 

Soil 

Use a well-draining soil mix with good aeration, as Philodendron domesticum prefers a moist but well-draining soil.

Fertilizer

Feed the plant with a balanced fertilizer once a month during the growing season, from spring to summer.

Pruning

Trim any yellow or brown leaves, as well as any leggy or overgrown stems. Pruning can help promote bushier growth and keep the plant looking tidy.

Repotting

Repot the plant every 2-3 years, or when the roots start to outgrow the current pot. Choose a pot that is one size larger and use a well-draining soil mix.

Pests

Keep an eye out for common houseplant pests such as spider mites, mealybugs, and scale insects. Regularly inspect the leaves and stems for any signs of pests and treat them promptly. 

Toxicity

Philodendron domesticum is toxic to pets and humans if ingested. Keep it out of reach of children and pets, or choose a safer plant if you have pets or young children in the house.
