In this article, we will be teaching you to make your own wooden flower box. This DIY tutorial will be using a basic rectangular design which is versatile for different applications. Here are the needed materials and steps to build a flower box:

Materials:

  • Wood boards – Cedar boards which are 1 inch or 2 inches thick, length will depend on the size of your flower box
  • Wood cleats
  • Screen or Vinyl liner
  • Galvanized screws
  • Brackets

Tools:

  • Electric drill
  • Tape measure

DIY wood flower planter box

Steps in Building a Flower Box:

Decide on the size of your flower box. To determine the size, consider the following factors: the amount of plants and flowers you will be growing in it, the number and sizes of planters/ pots/ containers you will be placing inside (if any) and the size of the area you plan to put it. Remember, that its size must be balanced and proportionate to your garden, deck, patio or balcony.

Cut and assemble the boards. Before cutting your boards, here are some tips you need to keep in mind when buying wood. First is to make sure that you go with wood species that are resilient when wet and can withstand harsh outdoor elements. Go for untreated cedar because aside from being durable, it is unsusceptible to rotting and insect resistant too. Cedar also lasts long despite being exposed to sun or rain. If you have a much bigger budget for the project, you can also use Redwood. When cutting your boards, use a measuring tape to measure each size you need. Mark your boards using a pencil then use a saw to cut it into pieces. Make sure to cut it straight or if you are a bit hesitant in doing so, you may always ask your supplier to cut the wooden boards for you. You will be needing 2 pieces for the sidings, 1 piece front panel, 1 piece back panel and 1 piece bottom floor board.

Fasten boards together. Create pilot holes at the end of 2 boards (1 side panel and front panel)  which you will be connecting. Place them together at a 90 degree angle, and drill 3 holes which are equally spaced from one another at ¾ inches from the end / edge of the front board. The purpose of pilot holes is to keep wood from splintering. After drilling the pilot holes, line the boards together then fasten using galvanized screws. Use an electric drill or screwdriver to attach screws to boards. Repeat the same process for the remaining boards (1 side panel and back panel). Once fully attached to each other, you now have a box like structure which is open on top and below. Measure the inside length and width to determine the size of your bottom board. Attach the bottom board to your box by using galvanized screws and an electric drill.

Add cleats and drainage holes. Cleats are important as it adds a profile to your flower box and it ensures that it doesn’t damage floors or railings. Drainage holes, on the other hand, are for preventing plant diseases such as “soggy feet” which is caused when the roots sit in wet soil for too long. To add drainage holes, simply flip your flower box over then drill 4 to 5 holes with a minimum diameter of ½ inch.

Insert a liner. Cut a piece of vinyl or nylon screen to fit the bottom of the flower box. This will hold the dirt and gravel in place. Remember to cut drainage holes in your liner too and make sure that they line up together. Use nails to fix it in place.

Add finishing touches. Sand any rough edges using sandpaper or a sander. Finish it off with a wood stain or paint of your choice, or if you want you can leave it unfinished for a natural look. Leave the inside part to avoid contamination.

Cultivating Flowers in a Flower Box

After building your very own flower box, it is now time to put in the flowers. Flower boxes are great for beginners as  it is a very easy way to start gardening.  

What you need:

  • Flower Pots – If you do not want to plant your flowers directly on the plant box, you can use pots and containers but make sure that they have drainage holes
  • Potting Mix
  • Gravel
  • Flowers

What to do :

Fill the flower box with some gravel for drainage. Then put the potting mix on top, keeping the flower box about ⅔ full. Sit plants in the flower box and decide on the arrangement. Transfer your plants from the pots to the flower box. Gently loosen without disturbing the roots and nestle them into the soil. Make sure that they are planted the same level they were in their original container. Add soil between the plants and gently firm.

Some arrangements you can consider:

  • Single Accent – composed of a single type of flower for a pop of solid color.
  • Multi-color – A mix of different varieties of the same flowering plant. This ensures a colorful mix but with a uniform texture.
  • Mixed Arrangement – This is composed of different types of plants and flowers. A combination of varying heights, color and texture. The perfect formula for a mixed arrangement is to choose a variety of plant or flower which is tall for height, a bushy plant for width and a trailing vine or flower which spills over the edge.
  • Round Design – Tall plants are placed at the center and trailing plants are placed around it.
  • Front Facing Design – Short plants and flowers are placed in front while the taller ones are at the back.

Some Tips in Building and Arranging your Flower Box:

  • Do not skimp on drainage. Flowering plants need a well drained soil so make sure that punch enough holes on planters or buy containers that have them. Drainage holes can go up to 1 ½ inches in diameter
  • Do not use pressure treated wood for flower boxers and planters. This type of wood may contain chemicals that are harmful to plants.
  • Always use galvanized nails and screws because they are rust proof.
  • Use annual or bedding plants for flower boxes because they bloom all year long. Always do some research first before you purchase your plants so you can get an idea of the lighting and temperature conditions they require.
  • If you are going to put pots inside your flower boxes and decorative containers, make sure that the soil surface is at least 2” below the rim of the pot. This way, water will not spill out and the soil will soak and be packed with moisture.
  • A well planned flower box has a combination of height and width so combine your plants and flowers wisely.
  • Maintaining a flower box : water your plants every 2 to 3 days and everyday during the summer season. For the best nutrient supplement,  feed your plants with an all purpose bloom boosting plant food
