Dry - Warm - Cool - Pest-free - Productive - Practical ... All Are Possible
The following instructions are available as a PDF in the Downloads section. Construction is not a complicated process, but it is made easier if you choose the most level spot (in full sun) you can find.
For information on the safety of using today's pressure treated pine, please see Keeping It Practical.
|6||2x10x8' pressure treated pine|
|2||1x4x8' pressure treated pine|
|4||16" wooden stakes, pressure treated pine|
|4||10' long, 1/2" electric metal tubing (EMT)|
|2 lb||3" screws (compatible with PT lumber)|
|1 lb||2" screws|
|16||1/2" EMT straps|
We caution against using thinner boards, such as 1" cedar fence boards. While inexpensive (and only 6' long), the pressure from the soil inside the filled bed will cause the sides to bow out.

|#2 Phillips-head screw gun or screwdriver|
|Pipe bender ***see note***|
Heavy gauge wire can be used instead of the hoops. Appropriate lengths are cut, arched over the bed, and the ends stabbed into the soil. They work well enough to support the row covers, but are not nearly as sturdy as the EMT pipe. Trellis material cannot be attached to wire hoops.
