What kind of support do philodendrons need to climb?
Philodendrons, like pothos, wax plant, and several other favorite vines, climb by means of little aerial roots which cling to rough surfaces. The support most people use for them is a length of red cedar with the bark left on it. Any rough wood will do as well. So will a smooth stake, wrapped in moss or osmunda fiber. Be sure to sink whatever you use all the way to the bottom of the container and pack it in with soil. Otherwise, it may topple over under the weight of the plant.
