Glazed ceramic pots have brighter color and a more finished look than their unglazed counterparts. The glazing also helps retain moisture, which is especially important for plants in full sun or that need a lot of water. They can also help reduce water use. Because they do retain more moisture, however, it is important to optimize drainage by using stones in the bottom of the pot and mixing sand into the potting soil before planting in a glazed ceramic pot. This will help prevent problems caused by overwatering or soggy soil.
Choose a location for the pot. Based on the needs of the plants you intend to grow in the pot and the aesthetics of the location, decide where your pot will be located and place it there before planting. A glazed ceramic pot is very heavy when filled with soil, and it is easiest to place while still empty.
Fill the bottom quarter of the pot with gravel or (if the pot is very large) river stones. The stones will help provide drainage, which is especially important with glazed pots as they don't allow water to evaporate through their sides.
Mix sand, potting soil and peat moss in approximately equal amounts in a wheelbarrow or a small pile next to the pot. Use a shovel to turn the soil and mix it together completely.
Fill the pot with the soil mixture, leaving about six inches empty at the top. Do not tamp or push down the soil. It should be left loose.
Wet the soil by filling the pot with water and letting it drain.
Dig a hole in the center of the pot. It should be slightly wider than the plant and deep enough to completely cover all the roots. If the plant is already in another pot, plant it to the same depth.
Sprinkle fertilizer in the hole, if desired. Fertilizer designed to help reduce transplanting stress can help the plant adjust after being planted in the pot. Follow manufacturer's directions for the fertilizer to determine how much to use. Do not add more than recommended.
Place the plant in the hole, adjusting the depth of the hole if necessary by adding or removing soil.
Fill the hole with soil while gently holding the plant upright. Put the soil in loosely, patting it down only enough to keep the plant in place.
Water the plant thoroughly.
