Terracotta, (from the Latin terra cocta), a type of fired earthenware, is a clay-based unglazed ceramic. Not watertight so the presentation quality of the planter is best preserved by treating the interior or exterior of the pot with a sealant prior to use or planting. This will also minimise the development of white salts due to water seeping through the sides of the pot and drying. The porous nature of the product also makes them prone to cracking in freezing conditions . Take care when moving as they can crack easily if knocked or dropped. Riversland is a comparatively lightweight and low cost product range.
