Most deciduous plants will recover and fill in the broken spaces. Some evergreens, especially upright evergreens like junipers can be so severely deformed that they never look good again. Wrapping with burlap can prevent ice damage. It keeps the branches close together so that the ice can't bend them over.

How do you protect junipers in the winter?

Mulch is an excellent way to prevent weed growth but it has to be used with care. I use cedar bark mulch myself but only apply it to a depth of five centimetres and keep it well away from the trunk or base of the plant. Good luck and happy gardening!

How cold can juniper survive?

Temperature and Humidity

Juniper bonsai trees should be grown outdoors year-round and cannot tolerate growing indoors. They are hardy, frost-tolerant trees that can withstand temperatures as low as 10 degrees Fahrenheit without protection.
