Water is necessary to carry nutrients through trees. It also hydrates the plants, allowing them to perform functions vital for their survival. Replenishing soil moisture is particularly important in the summer when trees lose water quickly through the leaves. Saplings are especially vulnerable to drought, requiring consistent moisture until their roots become established. Deep-pipe irrigation is one method of watering newly planted trees until they become established. Install the pipe at planting and remove it once the roots are mature enough to withstand dry periods.
Set the sapling in the centre of the planting hole. Do not backfill it with topsoil.
Insert a PVC pipe with a 4-inch diameter into the hole until it touches the bottom. Place the pipe 1 inch away from the root ball. Use a pipe long enough for one end to protrude 3 to 4 inches above the surface level after the hole is backfilled.
Fill the planting hole with topsoil. Firm the soil around the pipe and tree trunk with your hands.
Install one end of a garden hose inside the pipe sticking out of the soil. Screw the other end to a faucet and turn the water on to fill the pipe. Alternatively, carry the water in jugs and pour it down the PVC pipe. In general, saplings require 1 inch -- equal to 5 gallons -- of water a week for healthy root establishment.
