Should I put holes in the bottom of a planter?
Any water that pools at the bottom of a planter can allow bacteria and fungus to form and cause root rot, which can be deadly. Though every plant owner should know their individual plant’s care and watering needs, drainage holes in a planter allow any extra water to seep out. Containers without visible drainage holes can still support healthy plants, but only if you manage water carefully. The goal is to give roots steady moisture without letting them sit in a permanent “bathtub” of excess water, which quickly leads to rot and decline.
