Should I water an established, large Ponderosa that looks dry, and may have been impacted by very recent surrounding home construction? I have two trees right next to eachother in my backyard and at some point they were trimmed up to several feet, and they look dry or ill. The lower part looks like it is dying. A local commercial arborist who came out to assess them recommended giving them extra water and reassessing them in 2-3 years to see what the development/building the home impact might have been. Do you concur that they should be given extra water, and if so, how often and how much to give a very large Pondo? Or do you recommend other courses of action, if any? Thank you.
