This is one of the most common and important questions we get from urban gardeners! Proper drainage is absolutely essential for healthy plant roots, preventing waterlogging and root rot. So, let's clear it up.
The answer depends entirely on the specific planter box you choose. Many of our urban planter boxes, especially those designed for outdoors and balconies, come with pre-drilled drainage holes as a standard feature. You can usually find this confirmed in the product specifications.
However, some modern, self-watering planters use an innovative internal reservoir system. These do not have traditional bottom drainage holes. Instead, they have an overflow outlet on the side to prevent over-watering. For these types, you do not need to drill any holes.
What if you fall in love with a box that doesn't have holes? In that case, you would need to drill them yourself. This is often possible with planters made from wood, fiberglass, or certain plastics. We always recommend checking the material and manufacturer's guidelines before attempting to DIY.
Ultimately, always look for a drainage solution—whether it's pre-drilled holes, a self-watering system, or a layer of drainage material at the bottom. Your plants will thank you for it with lush, vibrant growth
