This imaginative flower box is 24” x 24” x 17 ¾"H, easy to build and attractive. The treated wood you’ll use to make your flower box can be left as is, but painting or staining will improve durability and enable you to harmonize it with other elements, either on your deck or in the garden. And while you’re at it, build a few more; you can dress up the flower bed, decorate the deck, or post them as sentries, one on either side of the front door!

Before Assembly

Treated wood should be handled with precautions.

  • Wear gloves and long sleeves when handling treated wood to avoid skin contact with and to protect against splinters.

  • Wear dust mask, eye protection, gloves and long sleeves when sawing, sanding or shaping treated wood to avoid skin contact with or inhalation of sawdust, to protect against splinters and to protect eyes from flying particles. When making cross cuts use a cut sealer as the factory-treatment rarely goes to the heartwood.

During construction:

  • Apply an appropriate "end-cut" preservative to protect exposed, untreated wood.

  • Use nails, screws, bolts, connectors and other hardware resistant to corrosion: stainless steel, hot-dipped galvanized, yellow zinc or specially coated for outdoor use. Ordinary fasteners will rust, causing unsightly stains, and will weaken and fail.

  • Make certain the wood is thoroughly dry before painting or staining, and follow the coating manufacturer's recommendations. Use only good quality oil or acrylic coatings on water repellent pressure treated wood.

  • Regularly apply a stain or a water-resistant product to waterproof the wood and reduce leaching: every two years on floors and every four years for all other surfaces.

  • Do not dispose of treated wood remnants or sawdust in compost heaps, wood chips, or mulch and do not use it as animal bedding or litter.

  • Never burn treated wood.
