Benefits of Raised Beds

First, you might be wondering why not just stick plants in the ground; why bother with raised beds? Raised beds are an excellent design for a number of reasons.

  • Raised beds improve drainage. In general, while plants need moisture, they don’t appreciate “wet feet”. Raised beds ensure good flow and drainage.
  • Raised beds improve aeration. An important component of good soil structure is air. Indeed, air comprises 25% of an ideal soil composition (25% air, 25% mineral soil, 45% mineral soil, and 5% organic matter). A raised bed allows you to fluff up the soil each season.
  • Raised beds add a sense of containment and order. Whether or not you have a raised bed within a structure, or with a natural border, they add a sense of order and organization to your landscape.

Raised Bed Inspiration

Next, let’s get some raised bed inspiration. As you can see, you can create a raised bed out of many materials and in a wide variety of shapes and sizes depending on your space and needs.

Not all raised beds have a border; these backyard beds were mounded up within the existing lawn.

This raised bed full of tasty herbs is located just off of a kitchen, making it easier to grab a fresh sprig of rosemary, thyme, sage, or whatever flavor is required.

5 Steps for Creating a Raised Bed

Now that you recognize the benefits and are inspired, how do you go about creating a raised bed garden?

1. Pick a spot.

Full sun, or a mix of sun and shade, typically works best.

2. Pick your design / material. 

Use materials that are locally available to you. Wood (cedar typically lasts the longest), bricks, pots, and poured concrete are some ideas; the material should make sense for your space (and wallet!).

3. Fill the Space with Top Quality Soil

Generally speaking, a raised bed is at least 6”-10” higher than the existing soils. Also, you’ll want a soil blend that has both mineral soil (the existing soil) mixed with organic matter (e.g. compost or some other form of soil amendment). Harvest offers pre-blended mixes, such as Garden Soil in Connecticut, Garden Blend in British Columbia, and a range of bagged soil products (Potting Soil, Potting Mix, Soil Amendments, Peat Moss, and compost-based products) available from our retail partners.

4. Plant

Seeds or starts, veggies or flowers, plant what makes sense for you! Your local garden center will have tips. Our advice:

  • Start out small and build from your successes.
  • Have fun! Grow what you know. Also feel free to experiment! Gardening is a forgiving activity that provides an endless opportunity for exploring and learning.

5. Maintain

ON THE SIDE: It can be nice to maintain the border of your raised bed by applying a 2-3” layer of mulch, or rock, gravel, or pavers to keep down weeds.

SEASON TO SEASON: Your soil will get depleted over time. We suggest adding a 2-4” layer of soil amendment, such as compost or a potting mix, and mixing it into the top 6” of the bed every couple years. Of course, as with everything, remember to water.

NOTE: With watering, plants typically prefer a few long drinks (a couple deep water sessions per week) over short sips (many short sprays of water per week).
