Raised Beds

Raised beds are easier to plant, weed, water and harvest than in-ground beds, and they produce bigger and better yields in a small space.

GOOD SOIL is the single most important ingredient for a successful raised bed planting. Fill it with a blend of soil that's loose and rich with nutrients and organic matter will allow the roots of your plants to grow freely, and ensure that they have access to the water and nutrients they need to sustain healthy growth.

If you'll be filling more than one raised bed, you may want to buy your soil in bulk — by the cubic foot or cubic yard. Use the Soil Calculator to figure out the total amount of soil you'll need for each bed. For most situations, we recommend these proportions:

  • 60 percent topsoil
  • 30 percent compost
  • 10 percent soilless growing mix that contains peat moss, perlite and/or vermiculite, such as Transplant Mix or Container Mix

Keep in mind that proportions are approximate because soil volume varies from source to source. For instance, if the calculator specifies .444 cubic yards of soil for your bed, go ahead and round it up to a half yard.

Calculating Volume for Pots and Planters?

Pots and planters should be filled with some kind of potting soil — not regular garden soil. The reason: Even loamy, rich soil from your garden is too dense for a container and it won't drain well.

To calculate the amount of soil you need for a container, estimate the number of quarts your planter holds. All of our soil mixes are sold in bags with quarts as the standard unit of measure.

When shopping for containers on our site, you'll see the soil capacity of each planter is given on the Specifications tab. Soil capacity is given for larger planters as well.
