What should I use to protect my lilac bush from frost tonight? And do I need to protect hydrangeas too?
If you feel the need to cover stuff, use fabric, not plastic. Lilacs have been around for a long time... you may lose some flowers this year, but the plant will be fine. Don%26#039;t know how tender the hydrangeas you mention are -- they vary all over the place, but if they grow ok in your area (as opposed to plants you have to take inside in the winter) they%26#039;ll be fine, too.
Reply:Cut up big plastic garbage bags and secure them over your hydrangeas. Your lilacs are probably too big to cover? Unless the lilacs are blooming, they%26#039;ll be ok.
Reply:the lilac should be okay if it%26#039;s an older bush...but a new planting should be protected... same with hydrangea if it has green buds showing, cover it!!!...... cover with cloth not plastic ...
Reply:Use cheese cloth or burlap, not plastic. But only cover your lilac bush and hydrangeas if they%26#039;ve started to bud, otherwise, they%26#039;ll be fine.
Reply:Have lilac bushes and hydrangeas for years and never covered them. The frost has not hurt them. They are hardy plants.
Reply:Don%26#039;t worry. Lilacs and hydrangeas are pretty hardy and don%26#039;t need to be covered to keep off the frost.
Reply:try a couple of towels just drap them over the plant during frost period.
