Cool October weather can fool you into thinking the watering can and garden hose are finished for the year. Newly planted trees and shrubs tell a different story because their limited root systems still need moisture even after summer heat disappears and leaves begin dropping. University of Minnesota notes that new plantings require regular, consistent watering while their roots become established, a process that can take considerably longer than one season. Getting fall watering for new trees right isn’t about soaking the yard constantly; it’s about delivering water where developing roots can use it without leaving them waterlogged. These practical rules can help protect the money and effort you’ve already invested in your landscape.
