Haven't needed to water it lately because of our crazy Florida rainy season. I apply that "citrus and mango" fertilizer from Home Depot about 4 times a year. Don't know much about PH, but for the last fifteen years my mango, lychees, jujubes, and macadamias have seemed pretty happy. Other types of fruit trees don't do well in my yard. My pomegranate, atemoya, and fig never did thrive. Black sapote and saphodilla don't do well here, either.
