I planted several different kinds of lavender in its perfect space last spring, and it grew, flourished and bloomed over and over again. I am a new gardener, so I was pleased as punch. I harvested the flower wands and pruned it to specifications last fall. It is late April in zone 5 (Chicagoland area) and there is no sign of life on these guys. The daylilies, oriental lilies, peonies and salvia are all coming back to life, but the lavender stays dormant. I had put hay down for the winter and have removed it, but have yet to amend the soil and add mulch this spring (stomach flu), but there should be some sign of life, right? Should I prune them down to the ground?
