Give your Philodendron Billietiae Variegata plenty of bright, indirect light to support strong growth and vibrant colours. This Philodendron tolerates a little dryness much better than soggy conditions! Allow the top 3 cm of soil to dry slightly before watering again. During spring and summer, feed your Philodendron at half strength with a balanced houseplant fertiliser every two weeks to support healthy new growth. Philodendrons adapt well to average household humidity, but will appreciate levels of 60% or higher where possible, with good airflow around the leaves. Provide a moss pole or other support to encourage larger, more mature leaves as your plant grows. Only repot when your plant becomes root-bound, moving up to a pot around 3 cm wider in diameter. Always use a light, airy and well-draining soil mix in a pot with drainage holes to keep its roots happy.
