A drainage hole in a planter is always ideal because it allows for any extra water to seep out of the bottom, which in turn helps keep the plant and its roots healthy. If a planter doesn’t have a drainage hole, we recommend treating your planter more like a cachepot by employing the double potting technique. Place your plant into a smaller pot with drainage hole(s) and then place the pot inside of your decorative planter. You can even line the bottom of the decorative planter with some gravel, which catches the extra water from the drainage holes and creates humidity which plants like.
