How to Build a Tree Planter Box UK

Tree planter boxes are a great addition to any garden or outdoor space, and can be used to provide shade, privacy, or simply as a decorative feature. Building your own tree planter box is a great way to save money and create a unique design that suits your specific needs. In this article, we’ll discuss how to build a tree planter box in the UK, step-by-step.

Step 1: Gather Materials

To build a tree planter box, you’ll need the following materials:

4x4 treated timber posts

Decking boards

Drill and screws

Measuring tape

Saw

Spade

Gravel

Soil and compost

Step 2: Measure and Cut the Timber

Measure the diameter of the tree trunk to determine the size of the planter. Cut the timber posts to the appropriate length for the height of the planter box. Make sure to use a saw that’s suitable for cutting through treated timber.

Step 3: Assemble the Timber Posts

Place the timber posts in a circle around the tree, making sure they’re evenly spaced. Use a drill and screws to attach the ends of the posts to form a secure circle. Make sure the posts are level and the circle is stable.

Step 4: Add Decking Boards

Fix decking boards onto the top of the posts, creating a base for the planter box. Make sure the boards are level and evenly spaced. Screw the boards into place using a drill and screws.

Step 5: Add Gravel and Soil

Fill the bottom of the planter with a layer of gravel to aid drainage. Add soil and compost to the planter, making sure to leave enough space for the tree roots to spread out. Tamp down the soil to make sure it's firmly in place.

Step 6: Plant Your Tree

Add your chosen tree to the planter, making sure it’s centred in the box. Gently fill the remaining space with soil, firming it down as you go. Water the tree well and add any additional soil or compost as needed. Mulch around the base of the tree to help retain moisture.

Step 7: Maintain Your Tree Planter Box

Regularly check the tree for any signs of stress, and water as needed. Prune the tree as necessary, making sure to keep it in shape and remove any dead or diseased branches. Additionally, make sure the planter box is free from weeds and debris.

Building a tree planter box is an enjoyable and rewarding DIY project. With these simple steps, you can build a sturdy and attractive addition to your garden or outdoor space that will bring pleasure for years to come.
