Abstract: A drainage tray suitable for use with plant pots is configured to collect and drain away excess plant treating fluids, such as water, fertilizer and the like, that drain from the plant pot. The drainage tray has a base member with a bottom having a side wall extending generally vertically from its periphery to form a reservoir with a generally open top and closed bottom. A drainage orifice in the base member connects to a tubular member, such as a hose, to drain the excess fluids from the reservoir to a suitable disposal site away from the area of the potted plant. Support members and stabilizer members are used to facilitate use of the drainage tray. The drainage tray prevents the accumulation of fluid near a potted plant that can damage or stain the deck, floor, sidewalk or other support surface and/or cause persons to slip and fall.
