Cut the Board

Cut the pine board into five pieces, three pieces 18 inches in length, and two pieces 6-1/4 inches in length.

Tips

  • If you purchase the pine board at a home improvement store, you can usually get an employee to make the cuts for you for a small fee.

Assemble the Flower Box

Stand two of the 18-inch pieces up on their long edges, and then place the third piece across the top, lining up the edges. Use a 1/8-inch drill bit to drill a pilot hole in each of the four corners to prevent splitting the wood when inserting the screws.

Hold the pieces securely in place and slowly drive the drywall screws into the pilot holes with the power drill.

Stand the box on end and hold one of the end pieces in place. Drill pilot holes and secure each end piece with screws.

Finish the Flower Box

Lightly sand the wood with your fine-grit sandpaper, and then stain or paint the flower box in your chosen color. Using a stain will leave the wood grain showing, while paint is opaque. If you use a stain, wipe the excess stain from the surface. A finish coat of polyurethane is optional.

Line the Box

Fold the sides down on a heavy duty 13 gallon size trash can liner and fit it into the box. Staple the plastic in place along the top edge. Trim away any stray pieces of plastic with scissors or a utility knife.

Prepare the Floral Foam

Cut the floral foam blocks to fit into the box with about one inch extending above the top edge.

Debbie Williams

Fill a bucket or sink with water and add the flower food according to the directions. Float the foam in the water and let it absorb water until it sinks – don't force it under the water or it will capture air bubbles in pockets and fail to hydrate the flowers properly.

Debbie Williams

Carefully place the water-soaked floral foam into the flower box. Secure the foam in place with adhesive waterproof floral tape, anchoring each piece onto the flower box. Wrap a final strip of tape around the top edge to secure the tape ends.

Purchase Flowers

If you have access to one, visit a local flower market to shop for your flowers (the smell alone is worth the trip!). You can also find affordable flowers at wholesale clubs. You can even harvest greens and flowers from your yard.

Look for a variety of textures and colors in greenery.

You can use as many flower types as you wish but choose at least one focal flower, one line flower and one filler flower.

Focal flowers, like roses, magnolias, hydrangeas, mums, carnations and peonies are single stem flowers that command attention.

Line flowers are tall and have many blossoms close to the stem. They are “showy” flowers like gladiola, snap dragons, delphiniums, and stock.

Filler flowers have clusters of individual flowers on a single stem like baby's breath, pom-poms, wax flower, heather and statise.

Process the Flowers

As soon as possible, make a fresh diagonal cut on each stem and place greenery and flowers into vases or buckets of clean water treated with flower food. As you begin working, make another diagonal cut to the desired length.

Strip the branches or stems of all leaves that will fall beneath the floral foam.

Debbie Williams

Place the Foliage

Start to establish the height of the arrangement by placing the tallest stems along the center line, varying the angle. Turn the box and check the other side.

Debbie Williams

Add each type of greenery in succession, making each type a little shorter and working your way down to the shortest stems placed near the base to cover the foam.

Debbie Williams

Place some stems facing down, hanging over the edge of the flower box. Elevate the box to place the final trailing branches.

Debbie Williams

Tips

  • You can use a few plastic containers or cans to elevate the box.

Place the Flowers

Start by placing a large, focal flower at the highest desired point but below the height of the foliage. Vary the height and depth of the rest of these stems. Insert each stem only once – don't remove and replace a stem after it is placed. It will leave an air hole and may deprive the flower of its source of water.

Debbie Williams

Add each type of flower, one at a time, varying the height and depth of each and spreading their locations throughout the flower box. Hold the stems near the base and carefully push them into the foam.

Hang the Flower Box

Insert an screw eye into each of the four corners of the flower box.

Debbie Williams

Attach a 12-inch section of chain to each of the screw eyes with an S hook. On each end, bring the two chains together and connect them to a 36-inch section of chain with another S hook.

Debbie Williams

Attach the chain to a secure anchor with another S hook. Be sure the anchor will support the weight of the flower box. This completed flower box weighs approximately 18 pounds. Hooks, chain and anchors are typically rated for the amount of weight that they can safely support.
