This vividly textured and colored begonia leaf is another plant from our windowsill garden at home. Kirk’s Hydro has some very large, round drip trays that are three feet across and about three inches deep. They’re useful to catch overflow from one very big potted plant, of course, but they have other uses, too.
Indoors, two are enough to hold all our house plants. Any overflow from watering sits in the tray and evaporates. You don’t want to leave your house plants sitting in deep water but a little bit of moisture to dampen the indoor atmosphere makes almost all plants a little bit happier. The trays also do their primary job and save the tabletop from any water damage. Having the plants grouped in one tray makes them look like a garden instead of just scattered plants with no relationship.
One year, I punched some holes in the bottom of a tray, then filled it with potting soil that I had mixed with some extra vermiculite so it drained very quickly. I planted directly in the tray to make a succulent garden for the front porch. Succulents have root systems that are shallow but wide, so it suited them perfectly.
