I have two peony bushes, this year neither bloomed. They both have beautiful full bushy leaves, but no blooms. I covered them over the winter - why did they not bloom and what can I do to correct this. Janine

Peonies are funny birds -- exasperatingly tempermental if given the wrong conditions or planted just a teeny bit improperly but extraordinarily vigorous, floriferous, durable, and long-lived in the right situation. Insufficient blooms or buds not opening can be caused by several factors: 1) Bud blast, a physiological disease caused by dry conditions during formation, a lack of potassium in the soil, root-knot nematodes, or plants being set in the ground a little too deeply ( eyes set no more than 1-2 inches below the surface). 2) Insufficiently cold winter. Peony lovers who live in the south or west almost always suffer this fate. 3) Or simply too much shade (less than 6 hours of sunlight per day) or not enough water. The only suggestion I can offer is to make sure your plants are receiving exactly the conditions they require, or adjust as necessary. Once they're happy, they'll bloom for you.
