Your dreams of gardening are about to come true, so get ready to roll up your sleeves and get started!
For the purpose of lining a wooden planter box, you may make use of materials like as plastic sheeting, landscape fabric, or liners that are waterproof. To fit the interior of the planter box, just cut the lining material to the appropriate dimensions, making sure that it covers the bottom and sides, and then trim away any excess. In this way, the soil is prevented from coming into direct touch with the wood, which in turn serves to extend the life of the planter box.

Step 2: Frame Layout


  • Lay out two 100cm, 60cm, and 40cm lengths to form the planner frame.

  • Check angles with a try square and fix with 7.5cm screws.


Step 3: Bottom Board Installation
