How do you keep Roses from dying in the winter?
Second, cones need to be well ventilated to prevent heat build-up on the inside during sunny winter days. Cut four to five 1-inch holes around the top and bottom of the cone. These holes will aid in ventilation and keep the air inside the cone from heating up, causing the rose to break dormancy.
Do rose cones get warm without ventilation holes?

How do you keep a rose cone from dying?
Cut four to five 1-inch holes around the top and bottom of the cone. These holes will aid in ventilation and keep the air inside the cone from heating up, causing the rose to break dormancy. It is also advisable to mound soil around the crown of the plant before putting the cone in place.
How do you attach a cone to a rose bush?
Use the twine to loosely tie the rose canes together, creating a quasi-enclosed area inside of them. Place the cone over the branches, enclosing them and the filling material of leaves, hay or straw.

Styrofoam Cones – How Do They Work?
Experiment Design
- Last winter, I set up the following experiment. Instead of a Styrofoam cone I used a Styrofoam fish box as pictured below. These boxes are used to ship fish around the country and can be picked up at restaurants and grocery stores for free. The thickness of the Styrofoam in these boxes is a bit thicker than some commercial rose cones, so my container might be a bit more efficient at tra…
Results
- The 2014-15 winter was a bit unusual. We got a bit of snow – maybe 5 cm (2″) in early January, but it did not stay around. The rest of January was cold, but mostly snow free. There was no real accumulation of snow until the first of February, when we received 10 cm of snow. New snow fall during the rest of February ensured that we had at least 10 cm of snow on the ground at any poi…
Styrofoam Cones – Do They Keep Roses Warm in Winter?
- The answer is yes and no. On two testing days, the temperature under the box was actually colder than the air temperature. The differences were small and can be explained by the fact that the Styrofoam box is an insulator. Changes in temperature will happen more quickly outside the box than inside the box. If the air suddenly warms up (either a warming trend or a sunny day) th…
Conclusions
- Styrofoam cones do keep the air under them warmer in winter, provided that there is a good seal between the soil and the cone. In areas that do not have reliable snow fall, it would be a good idea to use soil around the cone to make the seal. Styrofoam cones will not prevent the plant inside the cone from reaching freezing temperatures. In zone 5 (location of this experiment), a low tempera…
