I hope this helps.
How to get a plant out of a ceramic pot.
Better perhaps if it can be done whilst dormant and the roots are asleep anyway.
I have several like this in my living room.
You can tell that your potted plant has become root bound if the roots are growing on the sides of the pot inside or when the roots are sticking out of the drainage holes at the base of the pot.
Allow the force of gravity to gently ease the plant out of the pot.
Leave about 1 to 2 inches from the top of the soil to the pot s rim.
Use clean dirt in the new pot.
Slide a long bladed knife all round the inside between pot and plant then turn the pot upside down.
If the plant won t slide out easily tap the upside down pot against a hard surface such as a garden bench or nursery table.
Rotate the plant a few inches in both directions to loosen it up and allow it to fall out.
In general plant them to the same depth as they were planted before.
Dry with a lint free cloth.
If you have to wash off the dirt that is okay.
Then it can just lift in and out easily no problems.
Remove any plants from the planter and set them in a plastic container or another glazed ceramic planter until you re finished repainting.
Many ceramic pots come with a saucer.
A lot depends on the plant.
Set the pot in a shallow container for the water to seep out into.
You can use a knife to help separate the plant and the pot.
Remove the plant from it s old pot.
Rather than pulling the plant out turn it upside down while placing your hand over the top of the pot.
Put in the tree and spread out the roots that are left on the plant.
Thoroughly wash the planter with warm soapy water inside and out to remove dirt and debris.
Be sure to dump out any excess water so the roots do not become waterlogged.
Some handle transplanting very well others are very sensitive and can be hurt badly with minimal disruption of their roots.
Generally if the container is widest at the top so the soil could all slide out it is relati.
Put dirt in the new pot then water it so you know it s wet at the bottom.
The way to grow plants inside such ceramic pots is to use a plastic pot which fits inside the rim neatly.
Ideally the plant should fall out.
