My first raised bed - questions
(I live in Vegas, but not too too different from Phoenix/Tucson)
Constructed bed will be about 8L x 4W x 2H.
Is there a preferred choice of material? Wood planks or Bricks/blocks? Pros and cons of each?
Should the inner walls, no matter which material, be sealed or lined with anything to protect against temp extremes, evap, soil escaping, rot/degradation prevention etc?
The bottom will be left completely open on bare soil for drainage and rooting.
Thanks for any advice.
