Sterilising terra cotta pots.

Question

I have three very large terra cotta pots which are too heavy to move, so need suggestions on how to sterilise them as have been infested with Hydrangea Scale.
Many thanks.

Answer 1

You can scrub the pots still using diluted bleach water and remove any old soil and decay.
Allow the pots to air dry after cleaning.
