With a cold mass of air expected this weekend, Mountain View Trees is warning homeowners to take action to protect trees' buds, fruit and greenery.
The most susceptible trees range from citrus to jacaranda, catalpa, oleander, Eugenia and tropical or sub-tropical plants.
The tree-conservation group, which is fiscally sponsored by Palo Alto's Canopy, suggests protecting trees by covering them with burlap, sheets or tarps, using a frame or stakes to keep the covering from touching much of the foliage. Potted plants can be moved indoors.
If trees are well-watered, they have a better chance of surviving a freeze, according to the press release. Trees can recover faster after a frost if they are not pruned immediately, mushy fruit is removed, and fertilization occurs after the cold weather has passed, the release said.
