Dripline Irrigation

DRIPLINE IRRIGATION

If you have decided to install trees and shrubs on your property, you should be aware that the newly planted trees and shrubs require water at least once a week for the first few years until they become fully established. This is the single most important aspect of ensuring your tree’s survival. In the past we have had a large number of inquiries about the most efficient way to water 50 or more trees. We use drip irrigation in our nurseries and highly recommend it if you are watering trees that are spread over a large area. It is easy to install. Basically maintenance free, no need to drain it for the winter, and does not require large volumes of water so that wells can easily supply it. It waters only the tree, hooks up to a garden hose and is inexpensive.

Watering your Trees with Dripline Irrigation (4L/Hour Emitters)

(For 8L/Hour Emitters: cut the hours in half)

(For 2L/Hour Emitters: double the hours)

First Year:

First Three Months After Planting: Water twice a week for 4-5 hours at a time

August: Ease back on the watering. Water once a week for 8 hours at a time. The trees may look a little droopy. It is important to harden them off.

September: Pick up on the watering. Water twice a week for 5-6 hours at a time.

October: Ease back on the watering again. Water once a week for 5-6 hours at a time.

November: Ease back even more. Water once a week for 3-4 hours at a time. Water until the ground is frozen, approximately mid-November.

Second Year:

Mulching is a great idea for your trees. Add about 2-4 inches around the base of each tree.

Cut your watering back in half from the first year.

Third Year:

Water as required, with regular monitoring.

Watering your Trees without Dripline Irrigation

Good soil drainage is critical when watering your tree with a hose. Test your soil by digging 1½ – 2 feet into the soil. Fill the hole with water. If the hole maintains the water, the drainage is poor. If your drainage is poor, cut the rates in half.

First Year:

First Three Months: Twice a week, turn on the hose between a droplet and a slow trickle and leave it running for 5-6 hours.

August: Ease back on the watering. Water once a week for 8 hours at a slow trickle. The trees may look a little droopy. It is important to harden them off.

September: Pick up on the watering again. Water once a week for 6 hours at a time at a slow trickle.

October: Ease back on the watering again. Water once a week for 5-6 hours at a time at a slow trickle.

November: Ease back even more. Water once a week for 3-4 hours at a time at a slow trickle. Water until the ground is frozen, approximately mid-November.

Watering in fall is very important to prepare your trees and shrubs for winter.

Do not water your trees during a Chinook in the winter months. This will shock the tree. Please remember that trees and shrubs are living things.
