Levelling Raised Beds on a Slope

The wood for the beds is finally here! Putting the beds together is the easy part. The wood is hard white cedar that was pre-cut so that the planks interlock at the corners. I may reinforce with a few nails but it was no problem to get them attached and perpendicular.



The hard part is building up the downside of the bed and cutting into the upside of the slope so that the bed is level.

I started by putting down a few bricks to support the wood on the downside slope.

Then I dug narrow trenches into the upside where the boards could nestle in.
I used a level to determine when the boards were at the correct angle. My soil is clay-like and full of rocks and roots of all sizes. I wedged the clumps of clay, rocks and sod that I dug up underneath the downside boards and put bigger rocks against the downslope planks to prevent erosion. If the soil does end up washing away when it rains, I may have to invest in more bricks. (If you have done this and have any tips for preventing that, please let me know!)

Can you believe it snowed here this morning? Spring, are you really out there ??!!

Hey, another Nyacker has a copy of This Organic Life . . .

good luck with your beds; that is a lot of work.

I can't wait to see the finished garden, how large of an area are you raising?

It was freezing here today, too! Cold and blustery. If you see any Spring, send a little my way!

Very impressive raised bed building--I was looking at some triangular ones (behind Babbitt House) yesterday. and noticed in another sloping yard the bed were helped by metal spikes here and there. For the slopes of Nyack one could use very long and strong spikes.
