Do you have to worry about last night’s ice affecting your plants?
The short answer is no. Daffodils, tulips and other bulbs are particularly accustomed to dealing with seasonal cold snaps; although freeze prevents water from being able to travel through stems, so they may appear temporarily wilted. There could also be petal burn (browning) on early flowering trees and shrubs. But due to our cold spring most local trees and plants have been slow to leaf out or to flower, which means they will be unaffected.
