Do cast iron outdoor flower pots require specific types of mulch?
Cast iron outdoor flower pots are durable and stylish, but choosing the right mulch is essential for plant health. Unlike plastic or ceramic pots, cast iron retains heat, which can affect soil moisture and temperature. Organic mulches like wood chips or straw are ideal as they insulate roots, regulate temperature, and retain moisture. Avoid rubber or inorganic mulches, as they may trap excess heat. For best results, apply a 2-3 inch layer of mulch and replenish it seasonally. Proper mulching ensures thriving plants and long-lasting cast iron pots.
