I have a small evergreen shrub that gets frost burn in winter. I had been told to use tar paper on it over winter, but I was concerned that since it is a broad-leaved evergreen it might need light in winter. Is there a good way to cover it that doesn't set it back?

Out of interest, do you know what type of evergreen shrub we're talking about here? Also could you please post a photo on the evergreen shrub in question...– Mike PerryOct 9 '11 at 18:03

When plants go into winter dormancy they need little to no light. So it should be good.– nportelliMar 21 '16 at 12:42

Personally I would wrap the shrub, but leave the top open to the elements -- unless heavy snow load, damage, is a problem in your area, or the shrub you're protecting is susceptible to snow damage...
Bang into the ground a number of suitably sized timber stakes around the shrub:
Suitably sized timber stakes = 1inch x 1inch (25mm x 25mm) to 2inch x 2inch (50mm x 50mm), with a point cut in one end -- this will make driving them into the ground that much easier.
Cut the timber stakes to the height of the shrub you're protecting + 12inchs (300mm) minimum -- this will allow at least 12inchs (300mm) of the stakes to be embedded into the ground, thus giving your "protection system" adequate strength.
For maximum Wintertime protection:
Install the stakes about 6 to 8inches (150 to 200mm) away from the shrub you're protecting.
Wrap the stakes with something like:
Burlap.
A horticultural thermal/fleece blanket.
Chicken wire.
Plastic mesh.
Fill the enclosure with something like:
Non-diseased Autumn fall leaves.
Straw.
For minimum to moderate Wintertime protection:
Install the stakes as close as you can to the shrub you're protecting.
Wrap the stakes with something like:
Burlap.
A horticultural thermal/fleece blanket.
