Heat-stressed trees can’t say they’re thirsty — arborists offer advice to keep them alive

When crushing heat hammers the Bay Area, residents are advised to not only stay hydrated themselves, but give their trees a drink as well.

Temperatures have soared across the region this week, hitting a record-breaking 116 degrees in Livermore on Tuesday and smashing records in King City, Santa Rosa, Napa, Redwood City and San Jose as well. As a result, drought-stressed trees are suffering even more, said arborist Darya Barar of East Bay-based HortScience/Bartlett Consulting.
