Will Bonide All Seasons Horticultural Spray Oil help with grass browning/thinning?
Bonide All Seasons Horticultural Spray Oil is not labeled for use on grass. We recommend contacting your local cooperative extension office and describing the problem to the master gardener on staff. He/She should be able to help you identify the cause of browning/thinning and they should be able to help you select the correct product for your needs.
