A spring cleaning effort is scheduled for Salt Lake's urban forest.

The Urban Forestry division of the city's parks department will spray trees in city parking strips, public golf courses and parks.The first-ever application of horticultural oils and soaps to the city's linden and maple trees will control aphids and other harmful insects. Both sprays are environmentally safe, according to City Forester Steve Schwab.
