Things Needed
Peonies have been grown in Minnesota for more than 100 years . pioneer carry peony start with them as they settle the realm , beginning a tradition of growing this herbaceous perennial in the cool Minnesota summers where peony thrive . Cool summer also stand for cold winters , however , and peonies die to the land with the first hard frost . The hardy crown survives under the snow and sprouts readily the following leap , but despite their knotty nature , peonies do need care when temperatures throw away . Preparing your peonies for winter will keep them blossom next spring .
Step 1
make out back peonies within 2 in of the ground after the first hard frost , when the plant shows obvious damage . Cutting down a paeony earlier prevent the plant from store intellectual nourishment for the undermentioned springtime . Although peonies pull round an casual former passementerie , they are slowly weakened by overly eager nurseryman who cut them down too other year after twelvemonth . To prevent transferring potential disease from flora to plant , the University of Minnesota Extension suggest spraying or dipping pruning shears with a 10 percent bleaching agent solution between cutting , especially if a plant bear witness signs of disease .
Step 2
Clear any fall leaves or other detritus from the peony . Toss the cutting in the trash . keep the orbit clear-cut is the best prevention against botrytis and other fungous diseases . Do n’t compost peony fixings ; fungous diseases may be torpid and could re - taint the plant .
Step 3
Work compost into the first 2 inches of dirt around the paeony . peony are fast - arise plants that bloom heavily , and , although they are tough plant , they react well to the extra boost . Compost will provide nutrients as the ground warms in spring , when the peony puts on the most growth .
Step 4
environ the paeony with mulch . Deb Brown of the Minneapolis - St. Paul " Star Tribune " recommend place 4 to 6 inches of mulch over perennials to insulate the ground and prevent peony crowns from heave up during freeze - thaw cycle per second . It also provides extra tribute for the peony during other thaws , when the plant life may station up shoot if the ground is warm too quickly . A thick layer of mulch also keeps the soil from drying in instance of short or no snow .
