Do Concrete Planter Boxes have built-in drainage?

Concrete planter boxes are a popular choice for outdoor and garden settings due to their durability and aesthetic appeal. However, one common question is whether they come with built-in drainage. The answer depends on the design and manufacturer. Many concrete planter boxes do not have pre-drilled drainage holes, as this allows for customization based on the user's needs. Without proper drainage, excess water can accumulate, leading to root rot and other plant health issues. To ensure healthy plant growth, it is recommended to drill drainage holes at the bottom of the planter or use a layer of gravel to facilitate water flow. Always check the product specifications or consult with the seller to confirm if drainage features are included. Proper drainage is essential for maintaining the longevity of both the planter and the plants it houses.
