Spiraea<\/em> is a large genus of showy, flowering shrubs in the Rosaceae (rose) family, and cold-hardy garden varieties typically handle most cold or wet weather conditions with ease \u2013 but there are a few exceptions.<\/p>\n

The many landscape varieties common in cultivation<\/strong><\/a> feature dazzling clusters of pink, mauve, or white flowers that bloom in spring or summer, depending on the type.<\/p>\n

Many have fantastic, color-changing foliage that emerges in fiery tones then transforms into shades of bronze, gold, and a range of greens over summer, finishing the growing season with a pretty fall display of burgundy, orange, scarlet, and purple.<\/p>\n

Robust and tough, most are hardy in USDA Zones 4 to 9, with a few that can survive in colder Zone 3 climates.<\/p>\n

Once established, they don\u2019t need a lot of special care to survive frigid temperatures \u2013 but a few steps can help ensure their vibrant return in spring.<\/p>\n

To keep your shrubs in top shape, join us now for a look at how to care for spirea shrubs in winter.<\/p>\n

Here\u2019s what\u2019s coming up:<\/p>\n

All varieties of spirea are deciduous<\/strong><\/a>, which means they prepare for winter by losing their leaves and entering a dormant period.<\/p>\n

Healthy, mature shrubs that are rated hardy for your area require little extra protection from the elements.<\/p>\n

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

However, newly planted varieties and container plants can benefit from some protection from cold temperatures, freeze\/thaw cycles, or soaking rains.<\/p>\n

Protection from freeze\/thaw cycles is important because they can cause a few problems like heaving, which can expose the crown to drying winds and freezing temperatures, or cause broken and torn roots.<\/p>\n

And in areas with warm, wet winters, oversaturation from heavy rains can lead to root rot.<\/p>\n

Let\u2019s look at how to deal with these situations.<\/p>\n

Tips for Overwintering Spirea<\/h2>\n

The best cold weather protection for all spirea varieties is for them to enter dormancy in a healthy state.<\/p>\n

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

The following tips help ensure vibrant, healthy shrubs are ready for dormancy before the coldest weather arrives, and that they stay dormant until spring.<\/p>\n

1. Prune Lightly as Needed<\/h3>\n

After shrubs lose their leaves, remove dead or damaged branches.<\/p>\n

But don\u2019t prune vigorously after midsummer \u2013 pruning promotes tender, new growth, which delays dormancy and is easily damaged by a hard, early frost.<\/p>\n

For the pruning lowdown on both spring- and summer-flowering varieties, read our guide on how and when to prune spirea<\/a><\/strong>.<\/p>\n

2. Stop Providing Fertilizer<\/h3>\n

To ensure plants harden off sufficiently, stop fertilizing six to eight weeks before the first frost.<\/p>\n

Withholding fertilizers helps to slow the development of new growth late in the season.<\/p>\n

3. Water<\/h3>\n

If rainfall isn\u2019t adequate, water spirea \u2013 particularly new plantings \u2013 regularly and thoroughly until the ground freezes.<\/p>\n

Be sure to water to a depth of 12 to 18 inches to ensure the entire root ball receives moisture.<\/p>\n

4. Mulch<\/h3>\n

The roots of new shrubs and those planted late in the season need to be protected from heaving.<\/p>\n

After the first hard frost, or once the ground is frozen, place a four- to six-inch layer of mulch over the root zone and around the plant\u2019s base.<\/p>\n

Materials such as shredded leaves, sawdust, or straw make good winter mulches<\/a><\/strong>.<\/p>\n

If hungry rodents gnawing on the bark are a problem, keep the mulch four to six inches away from the trunks.<\/p>\n

5. Protect from Pests<\/h3>\n

You can also protect plants from nibbling rabbits by wrapping galvanized hardware cloth or small-gauge chicken wire around the base.<\/p>\n

Tie branches toward the center then encircle the stems at the base with hardware cloth, sinking the base of the cloth into the soil or mulch. Remove in spring.<\/p>\n

\n

23-Gauge Hardware Cloth<\/a><\/strong><\/p>\n

Hardware cloth is an outstanding choice for pest control \u2013 this three-by-10-foot roll is galvanized and double-coated in zinc for rust protection, and is available at Home Depot<\/a><\/strong>.<\/p>\n

Container-grown plants are often more susceptible to harsh weather than in-ground ones \u2013 we\u2019ll cover the best ways to protect them next.<\/p>\n

Container Care<\/h2>\n

With container-grown shrubs in cold climates, the main area of concern is the roots, which need to be protected from freeze\/thaw cycles.<\/p>\n

After the first frost, withhold water and fertilizer. Move containers to a protected site, such as against foundations or in an unheated garage or shed.<\/p>\n

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

If containers are left outside, apply a four- to six-inch layer of mulch \u2013 like shredded leaves, sawdust, or straw \u2013 over the soil surface.<\/p>\n

If needed, wrap just the containers with bubble wrap or an old blanket to provide extra insulation against freezing temperatures. Do not place these coverings over the plants.<\/p>\n

Remove the mulch and covers in early spring, or once overnight temperatures remain above the freezing mark.<\/p>\n

For areas with mild, wet winters, overly wet soil is a concern because of the potential for root rot.<\/p>\n

To protect against rot, ensure containers have adequate drainage holes and that they\u2019re filled with well-draining soil.<\/p>\n

Remove saucers from under pots to prevent standing water and elevate pots with bricks or pot toes to keep water flowing away from the roots.<\/p>\n

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

Plastic Pot Toes<\/a><\/strong><\/p>\n

Pot toes in packs of 12 are available at Home Depot in terra cotta<\/a><\/strong> or black<\/a><\/strong>.<\/p>\n

In regions that typically receive heavy rainfall, tilting containers on their side can reduce the amount of water potted plants receive through the winter.<\/p>\n

Gently turn containers onto their side so they\u2019re slightly tipped at a 20- to 45-degree angle, swinging the pot mouth to the leeward side of prevailing weather systems.<\/p>\n

Don\u2019t lay them flat on their side or you\u2019ll lose soil. Use a couple of pieces of wood if needed to securely hold your containers in place.<\/p>\n

Or if your pots are easily manageable, move them under the eaves or into the rain shadow of fences or walls.<\/p>\n

Set pots upright or move them back into the garden in late winter, or once heavy rainfalls have abated.<\/p>\n

Indoor Care<\/h2>\n

Bringing potted spirea inside for the winter is another option.<\/p>\n

To move containers indoors, choose a cool location with temperatures in the range of 40 to 50\u00b0F with a bit of light \u2013 an unheated garage, mudroom, or shed are good options.<\/p>\n

Avoid exposure to warm temperatures and long hours of artificial light, which can cause plants to emerge from dormancy too early.<\/p>\n

And although they\u2019re dormant, indoor containers should be watered lightly every four to six weeks to keep roots healthy and viable.<\/p>\n

Move containers outdoors again once the days start to lengthen and overnight temperatures remain above freezing.<\/p>\n

Cozy and Content<\/h2>\n

Left to their own devices, spirea shrubs are cozy and content in dormancy and readily able to survive cold conditions until spring \u2013 but sometimes they need a bit of extra help.<\/p>\n

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

For new plants, give the root zone plenty of protection with a thick layer of mulch.<\/p>\n

Lift containers to prevent them from standing in water, and remove catchment trays or saucers.<\/p>\n

Or move pots into sheltered sites to protect them from excessive rainfall, cold wind, and extreme temperatures.<\/p>\n

And use a bit of hardware cloth to thwart hungry pests looking for tender bark to nibble on.<\/p>\n
