Tip #1: Stop feeding rosebushes any granular type fertilizer August 15th. We want the rosebushes to get the message that it is time to store up strength for the winter and not focus so hard on growth and bloom production.
Tip #2: Stop deadheading now (first to second week of September) if you have not already. I just pull the petals off the blooms that are done and scatter them about the gardens and leave the rest of the bloom on the bush. This helps the rosebushes get the message that it is time to focus on storing up some energy rather than using so much on growth and bloom production.
Tip #3: Keep an eye on soils moisture throughout the winter as some light winter watering is usually needed to keep the bushes doing well for a great spring bounty of blooms.
Tip #4: Sometimes the winter snows melt-and-freeze cycles cause ice caps over the ground around the rosebushes. Thus, the needed moisture stops getting through. Sprinkling some Epsom Salts lightly around the bases of the rosebushes will help make holes in the ice caps, thus allowing the moisture to flow through better. The Epsom Salts will provide magnesium to the bushes, which helps them create new basal breaks in the Spring.
Here is a checklist that I use once the rosebushes have gone dormant due to the cold weather conditions:
Clear all debris and old mulch away from the rosebushes. Place two or three tablespoons of Super Phosphate around each bush and work into the soils lightly. The super phosphate moves slowly through the soils and will help keep the roots strong through the winter.
Mound all rosebushes for winter protection. An easy way to do this is to place a Rose Collar around the base of the rosebushes that need protecting. Fill rose collar 2/3 of the way with the garden soils and very lightly water to settle the soils within the collar. Add a bit more soils due to settling. Top off with mulch, such as shredded cedar mulch. Water very lightly again to settle the mulch. (Rose Collar is made of rigid material, open at top and bottom, about 12 inches in diameter by 7-9 inches in height, that you can fasten in a circle around the base of your bush.)
Prune hybrid tea and grandiflora rosebushes down to half their current height. (The lower growing and bushy floribunda rosebushes, shrub and miniature rosebushes will need a bit of a thinning pruning at this time.) This pruning helps prevent cane damage such as; breaking off clear down to the base of the bush, or smashing down of the overall bush due to strong winter winds whipping them or heavy snow falls breaking them over or smashing them down due to the weight.
Once the leaves have dried out a bit, they may be stripped off the bushes if so desired.
Mound up around the bases of climbing rosebushes and shrub rosebushes also; use rose collars if desired and follow above directions for fill. Wrap climbing rosebush canes with light fabric to protect from harsh cold winds, if desired. Climbing rosebushes on trellises connected to privacy type fences may not really need this.
Note: Garden Soils may be mixed with play sand to create a mounding soil that has better drainage capabilities. The play sand mixed in with the garden soils helps keep moisture flowing through the mounding soils and to the root zone, rather than holding it around the upper part of the bush where it may cause mold or fungus problems. See my “Winters Nap” article in next month’s In the Dirt Newsletter for more mounding information, as I use different methods based on the rose bed where the roses are planted.

Pamela has written a great article about mixing herbs in containers. Herbs are natural companions with different textures for interest. The herb mix of parsley, sage, rosemary and thyme offers lots of flavor from a small combination loaded with textural interest.
