We recommend removing the Oya watering pot at the end of the growing season to keep it in top shape. Remove plant growth from the Oya watering pot and wash it with 10 parts water and 1 part vinegar (a stiff brush can help), then let it air dry before storing. If you live in a climate at risk of frost, remove it from the ground before the frost and bring it indoors. Due to the porous nature of the clay, the Oya can be susceptible to cracking or shattering in freezing temperatures.
