Water your Philodendron when the top 50-75% of soil is dry. Water until liquid flows through the drainage hole at the bottom of the pot and discard any water that has accumulated in the saucer. Normal household humidity is fine for your Philodendron Birkin, but higher humidity encourages larger leaves
The majority of philodendrons require a balanced 20-20-20 fertilizer. Phosphorus (the middle number) is less important because philodendrons rarely bloom domestically, although it's still crucial for the plant's general health.
Philodendrons without solid green leaves can tolerate more light and should be exposed to indirect, bright light. The best possible spot for philodendrons is somewhere near a window, but where the sunlight does not directly hit the foliage. Too much sunlight can cause the philodendron leaves to turn yellow.
philodendrons prefer indirect or curtain-filtered sunlight but will tolerate low light. The common heartleaf philodendron (Philodendron scandens) will tolerate very low light. Night temperatures of 65 to 70 °F and day temperatures of 75 to 85 °F are ideal.
The ideal time to repot is in the late spring or early summer. Select one pot size up. Gently remove your plant from its old pot, and place it in the new one with fresh soil at the bottom and around its sides. Then, water the plant thoroughly.
