How to Build a Flower Bed to Suit the Space You Have

Follow a few basic steps, and you'll soon have more color, texture, and even fragrance in your landscape.

A flower bed gives you a place to plant colorful annuals and perennials that can fill your yard with beauty. And flowers, of course, are essential for butterflies and other pollinators, so creating more space for blooming plants will help roll out the welcome mat for these beneficial creatures. Like a blank canvas, a new flower bed offers you the chance to get creative and fill it with whatever you can imagine (quilt garden, anyone?). The options are nearly endless, but first comes the actual building part. This might seem like a daunting project, but with a little planning, preparation, and sweat equity, you'll soon be enjoying a more beautiful, flower-filled garden.

How to Prepare a Flower Bed

When you're starting from scratch, there are a few things to consider first. Here are the questions you need to answer:

Where will it go?

Anywhere from a corner of the backyard to your front entryway can make a great spot for a flower bed. You can place one along a deck or porch, underneath a tree, or around a garden feature like a pond, for example. If you plant near a driveway or along a curb, be sure to consider traffic safety when it comes to plant height, and if you live where it will get icy in the winter, keep in mind salt spray, which can kill plants.

How much sunlight will the bed get?

Many popular bedding plants like annual flowers require full sun, which means a minimum of six hours of direct sunlight each day. You can certainly choose a spot in part-sun or even a mostly shady area, but you'll be a bit more limited in what flowers will grow there.

What's the soil like?

Most flowering annuals and perennials appreciate a loamy soil with plenty of compost added to it. Make sure to rake away rocks or other debris from the site, break up any large clods of dirt, and add compost to enrich the bed and encourage healthy plant growth. It's also a good idea to do a soil test to find out if you should add any nutrients your plants will need to look their best.

Flower Bed Ideas and Designs

Once you've chosen a site, it's time for the fun part: Flower bed design. Here are some ideas to spark your imagination.

  • Looking to a make a statement in front of the house? Wrap a small flower bed around your mailbox, line your front walkway, add color underneath a tree, or surround the bases of the front porch risers.
  • Get geometric with a perfectly square, rectangular, circular, or even triangular bed.
  • Focus on tall or dense plants to help block unattractive backyard features such as air conditioners, trash cans, swimming pool heaters, or storage sheds.

Removing Grass and Building the Flower Bed

Unless you've got an already bare patch of earth, you'll need to remove the turf before planting your flowers. After marking the outline of your new flower bed with spray paint or white flour, there are two basic ways to remove the grass on the inside of your lines.

Dig up existing grass.

Digging out the grass can be hard work. Use a shovel to remove a section of grass from the center of your planned bed, then continue to remove turf by wedging the shovel (a hoe also works) under the edges of the grass. Then lift and peel the sod away. Once you have removed the grass, you can prepare the soil for planting.

Make a flower bed without digging.

Removing grass without digging is the lengthy-but-easy method. Simply cover the entire area of your future flower bed with several overlapping sheets of newspaper. Layer the paper at least six pages deep, then cover the newspaper with several inches of rich soil or compost. Water well. Over the next few months, the buried grass will die, and the newspaper will decompose while adding nutrients to the soil. For best results, keep the area covered for up to a year before planting.

Once the turf has been removed, outline the area with some landscape edging made of plastic, stone, brick, or wood. Some quirky materials you can use for edging include glass bottles, large seashells, or decorative metal fencing.

Build a raised flower bed.

There are a few ways to do this. You can use wood boards cut to the desired length. This lets you build whatever shape or size you desire. But if you prefer the simplest solution, there are raised flower bed kits that supply everything you need, and easily snap together with no need for sawing or hammering. Most kits create fairly small squares or rectangles.

If you're going to build your raised flower bed on top of existing grass, first cover the turf with a few sheets of newspaper, then top the paper with good-quality planting mix, and finish off with a layer of compost. If you want to build on top of concrete or another hard surface, you'll first need a protective bottom layer of plywood, landscape fabric, or heavy plastic sheeting to keep soil from slowly spreading out of the raised bed and discoloring the concrete.

Flower Bed Plants

You designed your flower bed, you removed the grass, you prepared the soil, and you edged your soon-to-be-planted site. Now it's time to plant! You'll want to choose varieties that do well in your climate, of course, and are suited to your site's exposure to sunlight. But beyond that, the best flowers are the ones you love the most.

Building a flower bed from scratch might seem intimidating, but actually, it's a fairly straightforward project that just about any enthusiastic DIYer or gardener can accomplish. The time spent in planning, designing, and preparing will be repaid many times over once you're admiring your beautiful blooms.
