How to Winterize Roses
The winter prep you’ll need to do depends on the coldest temperatures you get in your region and which kind of roses you have in your garden. But all varieties will handle the cold weather better if you water them well in the fall, before the ground freezes.
Preparing Roses for Winter in Cold Climates
In areas where winter is mild, but the ground still freezes (usually Hardiness Zones 6 and above), follow these steps to give your roses a little extra protection.
Protecting Roses in Extra-Cold Climates
In northern areas, where winter means sub-zero temperatures and frigid, drying winds, you may need to take more extreme measures for your roses to survive.
Tree Rose Winter Protection
Standard roses have their graft union near the soil line, making it easy to protect the most important part of the plant. Tree roses, however, have their graft union a few feet off the ground. Follow these steps to adequately protect them.
Winter Protection for Potted Roses
Overwinter potted roses by moving them into an unheated garage or to a sheltered place next to the south side of your house. In regions with extra-cold winters, protect each plant by placing it, pot and all, in a roomy cardboard box and packing the box with shredded newspaper or dry leaves. Surround the box with bales of hay. Plan early to protect your roses from the potential damage caused by freezing and thawing cycles in the winter. A little early preparation will go a long way in helping your plants to survive the coldest months of the year.
