<\/p>\n

The first summer I lived in Alaska, my neighbors brought over a bouquet of enormous, lush pink flowers<\/strong><\/a> that I had never seen before.<\/p>\n

Set in vases against the green walls in my home, I could\u2019ve stared at them for hours.<\/p>\n

I soon learned that peonies (Paeonia<\/em> spp.) are a big deal here in Alaska.<\/p>\n

Lots of Alaskan gardeners grow these cold-hardy blooms, which thrive in USDA Hardiness Zones 3 to 8.<\/p>\n

But what to do during winter? How much dormancy do they need?<\/p>\n

How many hours of cold temperatures? And is there anything you should do to keep your peonies warm during winter?<\/p>\n

In this guide, you\u2019ll learn everything you need to know about how to care for your peonies during wintertime.<\/p>\n

Here\u2019s what we\u2019ll cover:<\/p>\n

\n

Winter Care for Peony Plants<\/h2>\n<\/div>\n

There are three different types of peonies<\/a><\/strong>, all of which are long-lived perennials:<\/p>\n

    \n
  1. Herbaceous varieties, which are perennial shrubs that die down at the end of the growing season and require a period of dormancy and cold before blooming again the following spring.<\/li>\n
  2. Tree varieties, which can grow up to six feet tall, are deciduous shrubs and lose all their leaves in the fall, remaining bare-branched all winter.<\/li>\n
  3. Intersectional varieties, also called Itoh peonies, are a hybrid cross of herbaceous and tree types and boast huge flowers that typically bloom for up to three weeks \u2013 longer than either herbaceous or tree types.<\/li>\n<\/ol>\n

    Depending on the cultivar, petals can be single, double, or semi-double.<\/p>\n

    You can find out more about how to grow these lovely flowers and more about the different varieties in our growing guide<\/strong><\/a>.<\/p>\n

    After reading the above descriptions, you may have gotten an inkling of what a peony plant does during wintertime.<\/p>\n

    That\u2019s right. It sleeps.<\/p>\n

    Here\u2019s the funny thing about the beautiful Paeonia<\/em>: you\u2019ll actually need to pay more attention to winter care if you live in Zone 7 or 8 than you will if you are in Zone 3 or 4.<\/p>\n

    Most varieties require between 500 to 1,000 chilling hours, which amounts to approximately 20 to 42 days of temperatures between 32 and 40\u00b0F.<\/p>\n

    As bud development is stimulated by chill hours, your plants need about one month of chilly wintertime weather in order to bloom in the spring.<\/p>\n

    \n
    \"A\"A<\/figure>\n<\/div>\n

    If you live in Zone 3 to 5, you\u2019re pretty much guaranteed at least one month, if not six, of below-freezing temperatures.<\/p>\n

    I\u2019m looking at you, Alaska.<\/p>\n

    Peonies don\u2019t mind the extra freezing time that comes with long, cold winters, but if you live in Zones 6 to 8, you might struggle to get a full month of almost-freezing temperatures.<\/p>\n

    But since peonies don\u2019t grow from bulbs, it\u2019s not a good idea to pull them up and try to force them indoors<\/strong><\/a>, as you might with spring-flowering bulbs.<\/p>\n

    So how can you keep your peonies cold enough through a Zone 6, 7, or 8 winter?<\/p>\n

    Fear not, for I have a few tips.<\/p>\n

    Watch Your Planting Depth<\/h2>\n

    Peonies grow from tuberous roots with \u201ceyes\u201d that grow new shoots.<\/p>\n

    For a Paeonia<\/em> to thrive, it needs to be planted at the right depth.<\/p>\n

    For those of you who live in Zones 3 to 5, it\u2019s best to plant the tuber so that the little pink eyes from which the leaf stalks grow are two inches below the surface of the soil.<\/p>\n

    Can you see the little pink bud in the photo below? That\u2019s the \u201ceye\u201d of the plant.<\/p>\n

    \n

    It\u2019s recommended to plant it at exactly two inches deep. So get your ruler out to make sure the eyes get the planting depth they need.<\/p>\n

    For those of you in Zones 6 and 7, the eyes should be planted just one inch below the surface of the soil. And in Zone 8, just half an inch below.<\/p>\n

    This correct planting depth gives it the best opportunity to thrive and produce lots of gorgeous, heavy blooms.<\/p>\n

    The reason for the different planting depths is that peonies in warm areas will be exposed to cooler air temperatures, while those in cold areas will stay tucked just two inches down for a bit of protection during a winter that may get as cold as -40\u00b0F.<\/p>\n

    When and How to Cut Them Back<\/h2>\n

    Whether or not you should cut your plants down to the ground depends on what type of peony you\u2019re working with.<\/p>\n

    But regardless of the type, you\u2019ll need to let all the leaves die back naturally at the end of the growing season.<\/p>\n

    Once they\u2019re nice and yellow or brown \u2013 this will generally be after the first frost in your area \u2013 it\u2019s time to cut the stems of herbaceous cultivars to about an inch above soil level.<\/p>\n

    \n
    \"A\"A
    Photo by Laura Melchor.<\/figcaption><\/figure>\n<\/div>\n

    Throw trimmed vegetation away in a garbage can instead of on a compost pile.<\/p>\n

    This helps eliminate any diseases that may be lingering on the leaves from re-infecting the your plants the following spring.<\/p>\n

    You don\u2019t have to do anything special to tree types in the fall.<\/p>\n

    If you wish to, you may want to prune them lightly in the spring to preserve their shape, but that\u2019s not something to worry about yet.<\/p>\n

    And as for intersectional cultivars, you\u2019ll want to prune those back to about four to six inches in height, leaving at least one or two growth nodules on each branch.<\/p>\n

    In colder regions, however, you may want to cut intersectional peonies down to about an inch above the ground as you would herbaceous varieties, as the buds might not survive aboveground for the winter.<\/p>\n

    New stalks will grow in the spring, regardless.<\/p>\n

    To make sure you don\u2019t accidentally trample your precious peony\u00a0in the wintertime, use a plant marker to indicate where it is located.<\/p>\n

    Should You Mulch?<\/h2>\n

    The next step in keeping your peony happy during winter?<\/p>\n

    Smart mulching habits, which sometimes means no mulching at all.<\/p>\n

    \n
    \"A\"A<\/figure>\n<\/div>\n

    Since planting depth is crucial to the health of a peony, it makes sense that adding even an inch of mulch on top of the soil could impact the plant\u2019s ability to thrive and flower.<\/p>\n

    I once made the mistake of spreading mulch around the crown, and it didn\u2019t care for that treatment.<\/p>\n

    So then I moved it to my flower bed and left it un-mulched, where it was much happier!<\/p>\n

    Until my dog dug it up. I think she thought it was a stick I buried just for her.<\/p>\n

    \n
    \"A\"A<\/figure>\n<\/div>\n

    Newly planted peonies in Zones 3 to 5 can benefit from an extra-thin layer of breathable mulch \u2013 straw, for example \u2013 to help them stay cozy all winter long, and provide a bit of additional protection.<\/p>\n

    But even if you use straw, you don\u2019t want to place it too close to the stem of tree types.<\/p>\n

    Placing mulch right up against the stems can trap unwanted moisture in the soil around the tuberous root, causing the plant to rot or acquire diseases it wouldn\u2019t otherwise succumb to.<\/p>\n

    Those in Zones 6 to 8 should avoid mulching altogether.<\/p>\n

    You\u2019re already planting the eyes just an inch or half an inch below the surface of the soil so that they\u2019re exposed to as much cold air as possible.<\/p>\n

    Mulch would provide them with warmth they don\u2019t want.<\/p>\n

    Choosing the Right Cultivar<\/h2>\n

    While they do best in cold climates, those of you in Zones 7 and 8 and even parts of Zone 9 can help ensure success when you choose cultivars that are better adapted to your warmer climate.<\/p>\n

    Look for varieties that are described as early blooming, and single or semi-double flowered.<\/p>\n

    These types tend to do better in warm climates. \u2018Bowl of Beauty\u2019 is an attractive, early-blooming, single flowered cultivar to grow.<\/p>\n

    \n
    \"A\"A<\/a><\/figure>\n<\/div>\n

    Winter Care Means Eternal Blooms<\/h2>\n

    Okay, maybe not eternal. But if you take good care of your peony plants, they\u2019ll give you the gift of longevity. It\u2019s well-documented that these plants can live up to a hundred years old.<\/p>\n

    \n
    \"A\"A<\/figure>\n<\/div>\n

    So they\u2019ll probably outlive you. What a gift to the next generation!<\/p>\n
