Instructional video- raised redwood beds

Here's a great video on how to construct a very basic redwood garden bed, produced by Bruce Bauer Lumber and Supply in Mountain View, CA. I like the simple design and ease of construction:

This type of bed utilizes 2x12s, has only a few pieces, and will last a very long time. 

The GRK screws used are expensive and probably overkill for this little project, but I find they are a huge time-saver for larger projects or if you are building multiple beds. I'll talk about fasteners at a later time

These guys use galvanized wire for the bottom of the bed. This is perfectly acceptable to keep out rodents, but stainless steel gopher wire is a better choice as it will last longer in the ground. You can order online here or if you're in the Santa Cruz area Mountain Feed in Ben Lomond carries it as well.

It's also a good idea to use some 1/4"  redwood lath strips screwed along the bottom perimeter to ensure critters can't push their way in through the gaps left between staples. Plus, working with those fencing staples can be a pain in the ass for those who don't have a steady hand with a hammer.

I will post my own instructional video and make a page the next time I build some beds.
