Soil

Philodendron Birkin prefers really moist soil that drains well. Standard potting mix with perlite is an excellent choice for your Birkin as an indoor houseplant. Add some peat moss or mix in some organic compost to help the soil retain moisture.

Water

For your Philodendron Birkin, you want soil that will retain moisture but dry out between watering. Birkin plants tolerate drought better than over-watering.

According to schedule - Water once a week, but first check if the top inch of soil is dry. During winter, allow the soil to dry thoroughly before watering your plant.

Light

Philodendron Birkin is excellent for indoor conditions because it doesn't like low light, but it also doesn't like direct sunlight. The dark green leaves will get sunburnt if you expose it to full sun, but they will wilt if you have too little sun.

Pruning

There is no need to prune your Birkin unless there are dead or damaged leaves.
