How To Prepare Roses For Winter
Putting Your Roses To Bed:
This is always a melancholy time of year. -- Your roses have produced their bountiful bouquets all summer into late fall and now it's time to put them to bed. Literally.
In climate zones 6 or below, roses, even though quite hardy, need to be winterized in order to ensure they repeat their magnificent display year after year.
When I first began my hands-on education in roses over 10 years ago, I was somewhat ignorant on how to make these flowering wonders thrive. -- Most of what I've picked up along the way has been the result of trial and error.
Yes. I've allowed (unwillingly) a few roses to expire. -- After all, they are a tad high-maintenance. But for the most part, every hybrid tea in our garden has held a healthy residence the better part of nine years.
In short, I've learned what works and what doesn't when it comes to tending to roses in my neck of the woods.
The focus of this hub will discuss the few, short steps needed to prepare your roses for their long winter nap.
A Common Misconception:
The belief many people hold, that extreme cold kills roses, is somewhat false. It's true that if you allow your roses to experience long periods of below-freezing temperatures, they will die...
However, the single-largest danger to roses this time of year is the cycle of freezing and thawing, freezing and thawing, etc.... SO...
Primary Rose Winterizing Tip:
Once overnight temperatures are consistently below freezing, REGARDLESS of what daytime temps are, your roses need to be protected.
Yes. Winterizing roses is very important to keep them healthy. This hub will hopefully explain everything you need to know.
The three stages are: Pruning, Mounding, and Final Covering & Caging.
Pruning your rose bushes is the first step toward winterizing. A well-pruned rose bush in winter allows it to bounce back gangbusters in the spring.
Winter pruning, however, is not the same as spring pruning; where the objective is to stimulate growth. The goal of winter pruning is to prepare the plant for spring by getting rid of all dead, dying and unnecessary growth.
Roses healthfully sleeping are simply preparing for next year.
I suggest a heavy winter pruning and immediately covering up the plant, AKA winterizing.

WINTERIZING PRUNING CHECKLIST:
- Prune each rose bush to within 12" or less to the ground; making sure to expose healthy pith at the end of each cut.
- Seal the end of each cut with a school glue or other water-based sealant.
- Remove all canes less than the width of a regular-sized pencil.
- Remove all canes growing toward the center of the bush.
- Prune all deadwood and dying-wood canes.

WINTERIZING BEDDING CHECKLIST:
- Mound existing dirt and mulch, or other organic material over the bud union of each bush.
- Extend the mound of organic material as high as needed to cover most of the freshly-pruned canes. (It's OK to leave some cane tips exposed. Those will be taken care of during spring pruning).
- Continue to mound additional organic material and push toward center of bush to create a cone-like appearance.

MOUNDING OF ROSES:
Mounding, bedding, or covering rose bushes is the second step in rose winterizing.
The concept is pretty basic. Simply cover up the bud union (the point where the primary canes meet the main rootstock of the plant) with heavy organic material and continue to build up as much material as possible.
If possible, try to use as much soil near the base of the plant since it tends to maintain a more consistent temperature when insulated.
THE FINAL COVERING: CAGING
The finishing step in winterizing roses is what I call the final covering, or caging.
Basically, it's providing a "cage" around each bush (which can consist of any rigid, weatherable material) allowing for the final covering of organic material and top coat to remain in place.
I typically use wood since it holds up to the weather and can be re-used year after year.
NOTE: Material allowing for a lot of air infiltration has not worked as well for me in the past. Just an FYI.
WINTERIZING CAGING CHECKLIST:
- Stake the bush to allow the "caging" material to remain in place.
- Place caging barriers in place.
- Cover the bush with light-weight organic material, i.e. leaves, chopped leaves, straw, etc. and work down into all voids around bush.
- Top cover with a layer of heavier organic material, i.e. mulch or heavy straw.
- Wait until spring to come :)

These how to winterize rose tips are designed to give your roses their best chance to survive the bitterness of winter. At least they have in our garden.
Prepare yours for next year's buckets of blooms. ~
