I am trying to establish an asparagus bed. I did a lot of reading and went to great lengths to prepare my bed. I have a Honda tiller that is 12" wide. I tilled up a trench 12"x12". I left half the dirt in the trench and tilled in a couple of inches of garden center bulk mulch. I built a crown in the soil and placed the asparagus roots spread over the crown and back filled them about 2" with 50/50 soil and mulch. This all happened on the 24th of May, I put them on a drip hose so they are moist at all times. I didn't see any sign of life and dug one up Saturday and all I saw was 3 or 4 real fine 1/4" like fine white hairs. Is that a good sign? Am I being too impatient? How long should it take for them to actually come to life?
