Thin plum President fruit in May and June to improve fruit quality and prevent limbs from breaking. Water a newly planted plum tree weekly during the first growing season. Once established, President plum trees require very little supplemental moisture. However, soak the tree deeply every seven to ten days if you live in an arid climate, or during extended dry periods. Beware of overwatering your President plum tree. The tree can survive slightly dry conditions, but rot may develop in soggy, waterlogged soil.
