Beautiful Stone Raised Garden Beds

By: Sherri Ribbey
Don’t let challenging conditions stop you from growing the plants you love. Here's how to grow a garden in beautiful stone raised garden beds.

Beautiful stone garden raised beds filled with colorful plants

Gardening on a western slope in rocky soil with lots of sun and wind (plus deer and gophers!) is quite a challenge. But as you can see here, with stone raised garden beds and plants suited to the region you can get beautiful results. This zone 9 California garden started out as a rocky slope with soil too thin to support much in the way of plants. Excavating and replacing the soil can work for small beds, but this large space required a different approach.

Anatomy of a raised bed

Raised beds are a necessity for plants this lush and flower-filled in this area. They’re filled with a mix of topsoil and nutrient-rich compost that holds onto moisture and gives whatever’s growing there something to really sink its roots into. Besides making it possible to customize your soil mix to suit the plants you want to grow, raised beds make maintenance a lot easier — less getting down on the ground to pull weeds or deadhead flowers.

They’re made of stone dug up during the construction of the house. The bottoms of the beds are lined with gopher wire, a heavy duty fencing, to keep those furry pests from making themselves at home.

Stone raised garden bed layout

There are eight raised beds here, all 2 feet tall and 6 feet wide (which makes it easy to reach into for work) but in varying lengths from 12 to 25 feet long. They’re all connected by 6-foot-wide gravel paths. Small sharp-edged stones make up the path and knit together well so it’s easier to rake up the garden trimmings after a day of deadheading and weeding.

In the center path, a diamond-shaped raised bed filled with ground covers holds a dramatic New Zealand flax (Phormium hybrid) in an urn.

Keep plants in stone raised garden beds happy

Maintenance for this gorgeous garden is less than you might think, even in a hot, dry region. A layer of mulch added each year in early spring is critical for conserving water and keeping weeds down. The first layer of mulch is an inch or two of compost (made from garden debris, lawn trimmings and kitchen scraps) that slowly feeds the soil. This is topped off with another inch or so of shredded hardwood. A drip irrigation system on a timer keeps each plant in these stone raised garden beds watered efficiently and helps prevent fungal diseases that may develop from splashing water.

Color themes

Each raised bed has two shrub roses and a few other flowering plants for cutting. They bloom in colors that coordinate with the home’s interior so bouquets from the garden always look just right. The rich fall-like peachy oranges, pinks and reds with a pop of chartreuse are attention-getting. But without the blues and purples to contrast against them, they wouldn’t seem as intense and the beds wouldn’t have the same depth.

Let’s take a closer look at the plants that are in these raised beds.

Pincushion flower Scabiosa ‘Butterfly Blue’, Catmint Nepeta racemosa ‘Blue Wonder’, and Carmel creeper Ceanothus griseus horizontalis ‘Diamond Heights’: Letting plants spill over the top of the beds softens the hard lines and brings color up close.

Maintenance tips

  • Deadhead the pincushion flower to encourage more blooms.
  • To keep the catmint colorful, shear plants back by one third after the first flush, and you’ll get a repeat of blooms.
