Frost Proof Terracotta Pots.
Which containers are the more frost proof, terracotta or treated wood?
Terracotta pots are always going to be more durable compared to treated wooden ones.When we first use terracotta pots, if they are not glazed, we paint the inside and outside with Thomsons water seal. This helps seal the terracotta so that water does not enter the terracotta and freeze in the winter months cracking the pot.The only problem with this method is that the main advantage to terracotta is that it does soak up water into the sides of the pot.This water is released as the plant requires, leveling out the amount of water available to the plant between waterings.
