Thomas Writes: Cretan Terracotta and Frost

The first frost of the year is finally upon-us! After this wonderful event, there's no better time for me to write my first post on how you can help your pots survive the coming Winter.

All of my Cretan Terracotta is frost-resistant (technically speaking, not frost-proof), but it is easily to fall into a routine that may be harmful to your pots.

Rule No.1 - Drainage

This is the utmost important rule.

The most common cause leading to cracked pots is poor drainage. Poor drainage leads to standing water (which isn't very good for your plants anyway) and once the temperate drops below freezing, your standing water will freeze. As terracotta is porous, the micro-canals in the walls will be full of water - and we all know what happens when a can or bottle is left in the freezer. POP!

Rule No.2 - Raise your pots

Following Rule No.1 comes Rule No.2...

To assist drainage you should raise your pots off the ground. To do this you can simply use blocks of wood or stone (just remember not to cover the drainage roles underneath) and there are even decorative terracotta pot 'feet' you can buy online.

Leaving pots sat on flat surface will result in the drainage holes being effectively plugged.

Rule No. 3 - Over-Watering
