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'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'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'll be ok.
Reply:the lilac should be okay if it'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've started to bud, otherwise, they'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't worry. Lilacs and hydrangeas are pretty hardy and don'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.
