Frequently Asked Questions
How do I protect roses in the pot during winter?
- Remove the rose from the pot and bury the plant in your garden; or
- Bury the entire pot for the winter; or
- Place the potted rose in the coldest, darkest part of your garage. Be sure to place it on some sort of wood pallet to keep it off the cold concrete. Give it about one cup of water each month.
How do I winter protect climbers?
- Tie up the canes to keep them from whipping around in the wind. Create a soil mound at the base. You may want to wrap the canes in burlap.
Why do I have to bury the crown 2” deep?
- This is your first line of winter protection for the bud union. It will protect this susceptible junction from our winter freeze-thaw cycles.
What works best for fall maintenance?
- Clean up the garden of all debris. Tie up the canes of tall bushes to keep them from whipping around in the wind.
- Create your soil mound over the center of the bush.

Is covering the base with about 10 inches of soil sufficient, or are rose cones essential?
- Soil mounds are generally sufficient. Rose cones typically promote stresses on the plant because the interior temperatures on a 30-degree winter/spring day can reach up to more than 50-60 degrees.
What is the best way to winterize shrub roses?
- Choose those that are winter hardy
- Plant them properly with the bud union at least 2” below ground level

Should climbers be cut back for winter protection or not?
- No, just tie up the canes securely. Do any pruning in spring when you know what is “good” white wood.
