I cover mine with the leaves from the trees and when the weather warm up in spring and no more frosts I rake the leaves off and mulch them. I have Begonias and Spider Plants and other not winter hardy stuff come back every year.

It depend up on what type of flowers.
Roses - Protect for Winter
Here in Minnesota, you must protect roses not only against low winter temperatures, but also against fluctuating temperatures, particularly in spring.

The first step in avoiding winter injury is to keep your roses healthy during the growing season. Roses that have been fertilized and sprayed for insects and diseases are more likely to escape winter injury. Plants that have lost their leaves early in the fall because of disease or nutrient deficiencies are more susceptible.

Fertilize a final time in mid-August, using 0-20-20. Use no nitrogen to avoid encouraging new growth when the plants should be slowing down for winter.

Protect all but the hardy roses by mounding or tipping them in mid-October. Mounding is easier, but tipping allows you to save more of the plant from year to year.

To mound roses, cut them back to eight to twelve inches. Cover them completely with soil. Cover each mound with a couple feet of leaves or straw. A chicken-wire cylinder will keep leaves and straw from blowing off.

To tip roses, tie the canes together. Then dig a trench out from the base of each plant. Loosen soil around the roots with a garden fork, and tip each rose into its trench. Use the soil you removed to cover the trenches. Then add leaves or straw, just like mounding. Finish by covering with chicken wire to hold everything in place.

In April, begin to uncover mounded or tipped roses by removing the leaves or straw as they thaw. In two to three weeks, roses should be completely uncovered and lifted upright. Water them well and trim off dead or damaged wood. You're on your way to a new growing season of beautiful flowers.
With winter creeping closer, final preparations are needed for yard and garden plantings. Weather extremes and wildlife damage are two main concerns facing landscape plantings.

Winter mulches should be applied to protect perennial plantings from winter weather. These are suggested to help protect perennial flower plantings and strawberry beds from alternating freezing and thawing cycles over the winter, not from freezing. It's best to wait awhile before mulching perennials and strawberries until about Thanksgiving or later so the plants have gone dormant and the soil freezes to apply the mulches. Straw or evergreen boughs make good winter mulches.

For most perennial flowers, allowing the dead plant material to remain until spring may help protect the crown of the plant, although if the bed is mulched later this fall, it doesn't really matter. Most ornamental grasses provide interesting winter foliage effects when left standing.

Rabbits and mice are the primary animals that may gnaw on tender bark of trees and shrubs in winter. Putting up a barrier, such as poultrywire or hardware cloth, is the best defense. Put a fence around shrubs, and secure with a few stakes. Put a loose cylinder of hardware cloth around the trunk base of younger trees susceptible to mouse or rabbit gnawing.

First you need to trim them and then put Styrofoam cones over them and set weights of any kind to hold down the cones.
