What is the best way to age a large outdoor Terracotta pot?

Hi Sharon. I would paint them. Mix a little water in with the paint to give them more of a aged looked.

They can be painted with Buttermilk to age faster. Easy, cheap and environment ly friendly.

Martha Stewart has a video about doing this

I saw a tutorial on Martha Stewart where she dabbed mossy green paint on in irregular patterns and it looked great.

Add moss go to Pinterest and look for this procedure you can grow it on the pot as much as you want. I did it once on a strawberry pot that was slightly damaged turned it on its side and did a spilled either rock falling or fill with cascading flowers looks great

paint with plain yoguart and be patience they will turn green!
