These sturdy Philodendron selloums have been gratefully owned by my brother for about twenty years. Since I'm writing this in January, they are indoors now, but I got a quick picture of them this summer. I saw them today and they are flourishing. Houseplants love to be outside, if possible, when the weather is warm enough. The rain cleans their leaves and flushes the soil. A mostly shady spot in your yard is the best place for most houseplants. Even if they prefer a sunny window indoors, mostly shade outdoors is best. The light is much stronger outside than inside.
As a Philodendron matures it will develop a stout trunk-like stem. as you can see in the picture below. Their magnificent leaves will look their best if they are kept in very bright indirect light or get a little direct sun, preferably morning sun. Full afternoon sun from a southern or western exposure is probably too much.
The hardy Philodendron family includes many species and varieties that should be readily available at your garden center or florist. They are among the easiest of houseplants to grow.
- Bright indirect light or some direct sun. Full morning sun is good but only an hour or so of afternoon sun would be recommended.
- Water thoroughly when the top of the soil is very dry. A plant in a 10" (25cm) diameter pot, like the one in this picture,will use up to 2 quarts (or almost 2 liters of water). If it's in low light use 1 quart or 1 liter of water, unless the plant has wilted. In that case, give it a thorough soak.
- Fertilize regularly.
- Clean the leaves occasionally. A feather duster or microfiber cloth works well as does an occasional shower with the garden hose or in the bathtub.
