So, I thought I would bring you up to date on my low tunnel experiment. I didn’t get a chance to put a low tunnel to work in my garden, but did get one installed in Mary’s raised bed on Saturday March 15. The bed we used was her 4 by 12 foot bed which is bordered by 2 by 12s. The bed is filled with manufactured soil (50% leafgro-50% soil) and fertilized with 10-10-10 (one pound) to add .2 lbs. of N per 100 square feet. This picture shows the partially planted bed.
