To find your Cold Hardiness Zone, go to https://planthardiness.ars.usda.gov and enter your zipcode. Protect the following roses if you live in Zone 6 or lower (or colder): hybrid tea, floribunda, grandiflora, miniature, miniflora, climbers, tree roses, potted roses and roses that are going into winter unhealthy. A weakened rose may not survive the winter without protection. Newly planted roses or one year old plants need protection. For all the roses just mentioned, mulch up to 12” at the base of the plant. The roses that are winter hardy and need no protection are Own Root, Buck, EZElegant and OGR, or old garden roses.
Where a rose is planted also determines if it needs protection. For example, a rose will need more protection if it is located in a low spot in your yard or garden, or if it is in a place where it will get lots of wind. Wind dries out roses.. Roses planted next to the house may not need protection. As you survey your roses and their various locations, you will be the one to judge if they need protection or not.
