Is there any way to take care of this plant when it is small?
If you'd like this plant to grow nice and quickly, I would definitely recommend using Schultz All-Purpose Fertilizer! Philodendrons absolutely love liquid fertilizer, so I'm sure this will do the trick!
The most important thing is ensuring the potting media stays nice and humid and has good drainage. Otherwise, it can cause problems like pests, yellowing leaves, and even death.
Small philodendrons are usually more about choosing lighting, watering time, using potting media with good drainage, appropriate humidity, fertilizing during the growing season, and pruning when leaves are wilted or brown.
