Your winter garden guidebook to roses

Winter rose care can vary quite a bit, depending on where you live. For gardens that experience frigid winters in USDA Zone 7 and below, roses are entirely dormant, and most need protection to survive. At the other extreme, roses grown in mild-winter regions of Zone 8 and above may still bloom. In these warmer areas it’s also the time for pruning and for planting new bare-root roses.

No matter where you live, we’ll go over how to care for your rises throughout the winter season.

Winter Rose Care for Cold-Winter Regions: Zone 7 and Below

Frigid temperatures can harm rose bushes unless protective measures are taken. This is especially true for hybrid teas and other grafted roses, as the bud union( the swollen area at the base) is susceptible to injury from the cold. Shrub roses are more resistant to cold injury because they grow on their own roots.

Sub-zero temperatures and breeze can injury rises and dry out their canes( branches ). Protective measures for this region — which should have been initiated in autumn, after two hard freezes — involve mulching the base of each rosebush.

1. Once the ground has frozen, if it hasn’t already, add 12 inches of mulch around the base of your rises using compost or straw, which will help insulate the roots and lower canes. Brief periods of warmer temperatures can confound unprotected rises and induce new growth, but if they are properly mulched, they will remain dormant until springtime arrives.

2. Remove any debris such as fallen leaves and stems, which can harbor disease and harmful insects.

3. Attain sure roses don’t dry out. Check the clay around the roses during warm spells in wintertime, watering them if the soil is dry.

4. Potted rises should be brought indoors to an unheated, frost-free locating, such as a garage, shed or encompassed patio that ranges from 25 to 40 degrees Fahrenheit( minus 3.9 to 4.4 degrees Celsius ). Continue to water the potted roses but less often than in summer. Allow the clay to dry out before watering.

Winter Rose Care for Mild-Winter Regions: Zone 8 and Above

Winter is a busy hour for people who grow rises in warmer zones. Because of the mild wintertimes, roses don’t run totally dormant and can bloom through the winter months. However, they should be pruned back severely toward the end of this season in preparation for a lovely flush of springtime blooms.

Looking to add new roses to your garden? Winter is the best is high time to plant bare-root rises in warm-winter areas.

1. Don’t fertilize or prune roses now , even though they may still be in bloom, to help them slow down and get ready to be forced into dormancy.

2. Wait until six weeks before the last median frost to prune back rises. You’ll require a good pair of loppers, hand pruners and gloves.

3. Remove all remaining leaves from the rosebush as well as those underneath, which are a likely place for damaging fungi and insects to overwinter.

4. Most new rises are available as bare-root, and wintertime is the time to plant them when temperatures haven’t warmed up yet. You can find many tried-and-true rose ranges throughout nurseries this time of year, and mail-order companies have even more to choose from.

5. Select a spot in the garden for your new roses that receives full sunshine for at least six hours a day and has good air circulation, which helps minimize fungal disease.

Whether your rises spend the winter underneath a layer of mulch or are pruned back in preparation for spring, following these guidelines will ensure a warm season filled with vibrant, fragrant blooms.
