Is this safe to spray in the bed beneath established citrus trees if we protect the trunk and branches from the spray?

Hi Anonymous, thank you for the inquiry regarding our Extended Control 40-oz Concentrated Weed and Grass Killer. You need to protect desirable plants with a piece of plastic or cardboard or this will be harmful and you do not want any of the overspray to get on to the citrus that you would consume. The satisfaction of our consumers is very important to us. Please contact us at 1-800-917-5438 or email us at youropinioncounts@spectrumbrands.com so that we may better assist you.
