How much water does a sycamore tree need?

A general rule of thumb is to apply 10 gallons of water for every inch of trunk diameter when you water. Measure the trunk diameter at knee height. You can eyeball the diameter or hold up a ruler or yardstick to get the inches. The general watering formula is: tree diameter x five minutes = total watering time.

Shedding bark on some trees is a completely normal development. The bark of most young trees is smooth and thin. As the tree grows, the bark layer thickens with the outermost tissue eventually dying. Continued growth pushes the bark outward, sometimes causing the outer layers to crack.
