GROWING INDOORS
Philodendron Holtonianum is an exotic, glossy leafed plant that loves to climb. They require bright, indirect light and weekly waterings, along with an environment with high humidity. These aroids are natural climbers, so they will appreciate being given something to dig their aerial roots into and reach for the sky.
GROWING OUTDOORS
Philodendron grow very well outdoors, but they are not winter hardy and should be brought inside once temperatures dip below 55 degrees. Spring through Fall, keep your Philodendron in Full to Partial Shade and make sure it is not receiving any hot, direct sun. Water once your plant has had a chance to dry out, usually about every 4-5 days outdoors with moderate temperatures. During periods of extreme heat, you may need to water your Philodendron every 2-3 days.
