Raised Planter Beds

When we moved into this house, there were raised planter beds constructed out of wood.  They were very quickly destroyed by termites.  There’s a saying here in town – ‘there are two kinds of houses, houses that have termites and those that are going to have termites.’

Raised Bed Cosntruction

Our raised beds are constructed from 4×4 redwood posts sunk into the earth 10″ in each of the corners (except the two that but up against the block wall).  The two mid-section posts are not buried.  They are there to provide a place for the overlapping panels to screw into.

Panel overlap

The side panels are 26″ wide x 6′ long corrugated metal roof panels.  We cleared the rock down to the earth surface in an effort to bury the panels a couple of inches so Miss Roxy’s digging is harder to accomplish.

Each panel is attached to the posts with screws.

Corner detail

We added 40″ long 1/2″ electrical conduit pounded into the ground at 2′ intervals to keep the weight of the soil from pushing the panels out.

Conduit for stability

We will be picking up compost this weekend to fill the beds.  Once filled, the last bit of construction will be to add redwood 2x6s on the top edges to create a place to sit.

  1. Wonderful idea! Are the sides stable enough with the conduit support posts? No need to set the conduit in cement?

  2. HOw much did this project cost and where did you get your materials?

  3. Very good written information. It will be helpful to
    everyone who utilizes it, including yours truly :).
    Keep up the good work – looking forward to more posts.

  4. Thank you soooooo much for the info. I was searching for hours, had always great pictures, but no construction plans, until I found your page 🙂 🙂 I am living in Florida and will use some old hurricane panels to make the raised bed. Awesome info, thanks again!!!!

  5. metal panels look very stylish, just curious if they conduct heat through the soil and make it hot.

    • We have not had any problems with the metal conducting heat through to make the soil hot. We have most of our beds shaded because of the intense sun we have here.

  6. It’s been a few years since you posted this. How are the redwood posts doing? It seems like buring redwood 4×4 posts in the ground that they would be significantly rotten after 4 years or so.

  7. Thank you for sharing. This is a great idea. I read ahead and saw your soil didn’t work and that you ended up moving your beds. I live in Tucson. I’m very curious how your beds ended up working in the long run. I’m especially interested in what soil you had success with (or what additional problems you ran into.) I’m wondering if there’s an alternative to using wooden posts so that they won’t ever rot.

    We’ve been planning on a masonry raised bed, but we already have roofing material and my husband hasn’t been thrilled by the masonry idea. This is a great alternative.
