It happens to the best gardeners. We go out in the spring to plant our flowers, but the pots are stuck together from being stored all fall and winter. Don't fret. There's an easy way to get the pots unstuck.
Getting the Pots Unstuck
Place bucket of warm or hot water in sink, basin or washtub, and place outer pot in the water.
Pour the cold water into the inner pot.
Pull the inner pot out, or push the outer pot down. The temperature change in each should allow one to contract and the other to expand, freeing the two.
