Q. How do you protect plastic planters from the sun?

The pot-in-pot method also known as the cache pot method is considered to be one of the most effective techniques. This approach involves placing your plastic container inside of a larger container while allowing at least 2 inches of empty space around it. Place bark nuggets of a very large size in that area so that they can be improved even further. It will prevent the inner pot from overheating in the summer and shield it from temperatures that are lower in the winter.
