There are many different kinds of containers to choose for your outdoor potted plants. Glazed pots--which come in an array of colors, shapes and sizes--are typically clay or ceramic pots that have been protected or painted over with a clear or slightly tinted glaze. Although planting in glazed pots is similar to planting in other pots, there are a few things to keep in mind.
Choose a light-colored pot, especially if the plant is placed in full sun. Light-colored pots don't get as hot and the soil inside will retain moisture longer. However, since glazed pots hold moisture longer than unglazed clay or ceramic pots, choose a darker color pot if desired, but just water the plant more frequently than you would otherwise.
Protect the outside and inside of a glazed pot with a tile sealer, pottery sealer or silicone wax if you do not want it to craze or crack over time. Use a foam paintbrush to lightly paint the outside of the pot or spray it on if it came in a spray bottle.
Lay a 1- to 2-inch layer of gravel inside the pot before you add potting soil. Many glazed pots do not have a drainage hole and gravel will prevent the plant roots from sitting in soggy soil.
Place a smaller plastic plant pot with drainage holes on top of the gravel inside a glazed pot. This will both help with water drainage in pots without drainage holes as well as protect the pot from the wet soil from slowly soaking into the finish from the inside.
Elevate the pot--at least slightly--if it is placed on your deck or patio. Use pot feet or a plant stand to keep the mold from forming underneath from too much moisture.
Plant your plants in the glazed pots the same as you would in other pots. Use potting soil and fill within 1 to 2 inches of the pot's rim. Leave a bit more space if you want to add a layer of mulch for aesthetic purposes or to help retain moisture.
