This bed once built will take 4 yards of soil to fill it.
We got 4 yards of triple blend soil from a local garden Center. *** We also had some other uses for the soil, like filling all of our containers and adding some top dress to other areas, and for this reason, we used the following method:
Which in short is a form of gardening where your base layer is comprised of logs & branches.This is where the pruning of the trees on our property came in handy!
We trimmed our trees leaving anything one inch or less in diameter for our new wood chipper.
Any branches 1 inch and over were for the raised beds and placed on top of cardboard.
We also wanted to add another component of gardening called living soil. Over the last few years we have been composting our scraps. We were given a bail of straw from a family member to use as mulch.
Layer The Soil :
Cardboard helps suppress weeds, logs and branches, a layer of straw, home made compost, then about 6 to 8 inches of triple mix soil. Being mindful that we will be adding a layer of straw mulch once planted.
This isn’t a perfect living soil method but it is what we had on hand and any other soil building can be done in the future years with mulching and top dressing amendments.
Mulching The Outside
We had purchased a wood chipper from Amazon in hopes to eliminate our continued fallen branch problem every year. Also will save us money on buying mulch.
Take the grass sod off the surface and flip it upside down,continuing around the outer edges. On either side of the entrance we mounded a bit of triple mix soil, levelled it, then added our fresh mulch.
