Make sure you get a pallet that has been heat treated so it will be safe for growing food. Use a pinch bar to lever the timber slats from the frame of the pallet. Use a hammer and pliers to remove any nails from the timber.
Your herb planter can be any size you want. In this case, we had enough timber to make a top box, base box, legs, support posts and spacers. Before you cut the timber to size, use a tape measure, pencil and square to measure and mark it. Then use the drop saw to cut the timber to the following lengths:
Top box
90mm x 300mm (sides) x 2
90mm x 750mm (front & back) x 2
90mm x 750mm (base) x 3
Base box
145mm x 300mm (sides) x 2
145mm x 750mm (front & back) x 2
145mm x 750mm (base) x 2
Legs
90mm x 50mm x 300mm x 2
Support posts
90mm x 500mm x 2
Spacers
90mm x 150mm x 2
Put on your ear muffs and safety glasses. Line the timber up so that the edges are flush. Then use the nail gun to join the four pieces of timber to make the rectangular frame for the herb planter.
Line up your base pieces on the frame, making sure you leave a gap between the timber so that the soil drains well. Then use the nail gun to attach the timber to the frame of the planter.
The feet are important because they elevate the planter, help with drainage and keep the base dry so it doesn't rot. The heavy rail from the pallet is perfect to use for the feet. Attach the feet to the base of the planter using the nail gun.
Use the nail gun to fix the spacer to the end posts. Slide the end post onto each side of the planter, place the top box onto it and nail it into place.
Line both the base of both herb planters with weed mat. Add the soil and plant your favourite herbs into your new herb planter.
