About Ceramic Planters
Ceramic planter, also called unglazed clay, allow air and water movement through the sides of the pot. Air movement stimulates root growth, which results in healthier plants. But the clay also absorb moisture out of the soil, making ceramic pots a better choice if you tend to overwater or for plants that prefer dry soils.
Ceramic planter requires more water than plants in plastic planter. Ceramic pots do not dry out as quickly, but restrict air exchange. Ceramics are heavier compared to other materials used for pots so they can withstand the weight of a growing plant. They are lighter than concrete, making them easier to move.
Ceramic planters have thick walls that prevent rapid fluctuation in soil temperatures. But the clay also tends to retain heat longer than other types of planter materials. This could be an advantage or disadvantage depending upon your situation or plant needs.
