How to construct the Garden Maid irrigated flower box
Figure out what size box you would like to have. In this case we will build a 4’ x 5’ bed, 1' high.
Materials you will need:
- One 2" X 12" x 20' redwood board. Cut two pieces at 5' and two pieces at 4'. (If you don't own a saw, your local lumber yard will cut your boards to an exact size for about 50 cents per cut.)
- One 4" x 4" x 4' redwood board. Cut four pieces at 4" x 4" x 1'.
- A small box (24) of 3-1/2" galvenized wood screws
- One 4' x 5' piece of gopher wire with 1/4" squares
- Weed block fabric (5' x 6')
- One 18' piece of 1/2" round dowel
- One small box of tack nails or heavy duty staples
- Four 1/2" U-clamps
NOTE: Never use pressure treated or painted wood when growing edibles – toxins will get into your food.
*Diagrams below are not to scale.
- Level out the ground on the chosen site, removing rocks and weeds.
- Get your two shorter boards (in this case the 1' x 4's) and attach them flush to the 4" x 4" x 1' boards. (SEE FIGURE 1). Screw in starting with the 1' x 4' then into the 4" x 4" x 1' boards.
- Screw in the longer 5' boards flush with the 4' boards (SEE FIGURE 2). Now you should have a perfectly squared frame.
- Turn the bottom side up to install the gopher wire.
- Cut the gopher wire to fit the bottom, cutting it 1/2" away from the board edges (SEE FIGURE 3).
- Afix the wire to the box with tack nails or heavy duty staples.
- Cut a 1/2" hole in the corner you will use to run in your irrigation tubing.
- Flip the box top-side up.
- Cut your weed block fabric to a 5' x 6' piece and place in the bottom of the box on top of the wire.
- Fit the weed block fabric so that it will go evenly up all sides.
- Cut your 1/2" round dowels to the length of each side.
- Place dowels 4" from the bottom of box to hold weed block fabric in place between dowel and box wall.
- Tack dowels into place with tack nails or heavy duty staples. Fold the weed block fabric over the top of the dowels and tack into place.
- Cut a small hole in the weed block fabric in the same place you cut the wire hole for the irrigation tubing.
- Thread the irrigation tubing through garden box and attach to side of box with 'U' clamps (SEE FIGURE 4).
- Fill the box with the desired organic soil. Do not use mushroom compost when growing edibles, as they contain chemicals.
- Fit in irrigation sprinklers/drippers, attaching them to your main irrigaton line tacked to the inside.
- You are finished. Plant and enjoy!
