Philodendron Subhastatum Light Needs
Bright indirect sunlight is ideal for a subhastatum. They will do fine further back from the window in areas of medium brightness too.
How Often to Water
Water it if the top 50% of soil is dry, check it once a week. They don’t like a soggy bottom! It is important that philodendrons do not site in wet soil to avoid rot.
Tip: underwater this plant rather than overwater it, they must not sit in soggy soil as they get root rot easily. Check the soil and only water if mostly dry, and make sure you don’t leave the pot standing in any excess water.
Feed once a month in spring and summer with a balanced plant feed. Philodendrons growth seem to really take off when fed.
Philodendron Subhastatum Soil
A well draining potting mix with some added perlite is ideal for a philodendron subhastatum. They mustn’t sit in waterlogged soil, so make sure it has good drainage. It’s worth adding some perlite if you have a standard potting mix. For more on Philodendron soil see our guide on what to buy or how to make your own: Philodendron Soil.
When To Repot
Repot when it becomes root bound. The best time to do this is in spring, but you can do it whenever you see roots poking out the bottom of the pot to be honest.
Philodendron Subhastatum Humidity
50% humidity is perfect for a philodendron subhastatum. If your plant is in a low humidity area of your home, consider upping it with a humidifier or pebble tray to keep those leaves lush.
