All of our stoneware planters are 100% vitrified in the kiln firing- so even though they are unglazed they will not 'sweat' or leak water.
If you plant directly into the ceramic planter, stains and discoloration caused by the minerals and salts found in soil & water will seep into the surface and discoloration will occur.
While most discoloration can be removed, it is possible that you will not be able to remove them 100% so please take that into consideration when planting directly in the pot.
We ship all planters with a sturdy plastic insert to minimize the ceramic planter from this staining. However each planter has a drainage hole, and water will drain to sit in the catch plate, soaking the bottom outside of the planter depending on how much you water the plant.
To clean the pot and catch plate:
- Gently remove your plant
- Use a stiff brush to remove all the dried soil and debris from both the inside and outside of the pot and hose off. Do not let dirt / rocks / soil go down the drain if you do this inside
- Soak the discolored portion of your pot in a solution of 50% white vinegar & 50% water. for a few hours We used cleaning vinegar found at the hardware store
- Wash the pot in the dishwasher
We were able to remove all the of staining, but some stains may be stubborn and require longer soaking in the vinegar solution and faint discoloration might be impossible to remove completely.
I love to make & design vessels to house beautiful plants! You can see them all here.
