How much watering does a Sycamore tree need during summer east of San Diego (El Cajon/Crest area)?
During the first year, you’d need to make sure your tree gets water during extended dry spells, particularly in the summer months. But now that it’s established, normal rainfall should be enough to sustain it. I’m not sure if you’re experiencing very dry conditions out there, but a good way to tell if your tree is getting enough water is to look at its leaves. Drooping leaves are a sign of both over or under watering, so modify how much it gets based on that. Good luck!! Sources: http://www.fast-growing-trees.com/Instructions/AmericanSycamoreInst.
