Grow philodendrons just about anywhere. As houseplants they're that easy to keep! The plants grow best in medium or bright-light spots, but tolerate low light exceedingly well. Water philodendrons enough when the soil surface dries. They're tough enough plants they don't mind if you forget to water them now and again. Just take care not to overwater your philodendrons. They will rot if they're kept too wet. You typically don't need to fertilize philodendrons much, if at all, but they appreciate a feeding once or twice a year in spring and summer. Use any houseplant fertilizer (available from your local garden center) and follow the packaging directions carefully. Vining philodendrons are relatively slow growers, but can be cut back at any time to keep them compact and bushy.
