If you have any questions before ordering, feel free to get in touch.

Can I paint or stain my wooden planter?

Yes, you can paint or stain your planter. We recommend allowing the timber to fully dry before applying a water-based paint or stain. Adding a UV-protective finish will also help maintain the appearance over time.

How long will a pressure-treated wooden planter last?

With normal outdoor use, a pressure-treated wooden planter can last 10 to 15 years plus. Using a liner, ensuring good drainage, and we also add feet to most our planters to raise the base slightly off the ground which will all help maximise its lifespan.

Do your planters have drainage holes?

Yes. All of our planters are designed with drainage holes or drainage slats to allow excess water to escape. Proper drainage is essential to prevent waterlogging and keep plant roots healthy.

Are your planters pressure-treated?


Yes. All of our wooden planters are pressure-treated to protect against rot, moisture, and insects. This treatment helps extend the life of the planter outdoors, even in damp UK conditions, without affecting plant safety.

Does this need a liner?

We recommend using a liner, especially when planting directly into the planter. A liner helps protect the timber from constant moisture, extends the life of the planter, and makes future replanting easier.

How much soil will I need?

Based on internal planter dimensions.
