How to Plant a Tree
/Step 1: Choose the Location
Place your tree where it will thrive on your site. Plant with its mature canopy size in mind. Double-check your local city's requirements. Plant your tree at least 5 feet from underground utility lines. To locate your utilities for free you can submit a request by contacting 811 at 1-800-424-5555 or online at www.digsafewa.com at least 3 business days before planting.
Step 2: Dig the Hole
Dig the hole 2-3 times the width of the container and the same depth.
Step 3: Prepare your Tree
Support the root ball when you hold your tree.
Remove all tags, labels, twine, and burlap.
Remove the container and loosen the roots.
Cut an X-shape in the bottom if needed to loosen roots.
Step 4: Planting
Place your tree in the center of the hole.
Make sure the flare at the base of the trunk will be just above the soil line. Fill in the hole with the native soil to encourage root growth.
Before you fill in the soil, make sure the branches are facing the way you’d like them to.
Pack the soil down so the tree stands up straight and firmly in place.
Step 5: Water & Mulch
Watering: Slowly pour water around the base of the tree. Let the water soak in. (approx. 10-15 gallons for a young tree).
Mulch: Add 2-4 inches of mulch in a 3-foot wide circle around the tree, keeping it 2-3 inches away from the trunk to avoid rot.
Do not use fertilizer, potting soil, or any other chemicals when you plant your tree.
Add a stake for support only if necessary. Trees grow healthier and stronger without them!
Tree Care
Planting the tree is just the beginning. Learn how to help it thrive in its new home!
First two years: Regular Watering
Water thoroughly every 7-10 days throughout the dry summer months. Watering is not necessary during the rainy seasons.
Common Pests & Diseases:
Make sure the roots are pointed down and out, and that the root flare is above the soil line.
Do not pile the mulch against the trunk!
Aphids
Small green or black insects; sticky residue on leaves.
Solution: Spray with a strong stream of water or insecticidal soap.
Leaf Spots or Leaf Curling
Brown/black spots on leaves, possibly due to fungal infection.
Solution: Remove affected leaves and ensure good airflow around the tree.
Overwatering
Yellowing leaves or soft roots.
Solution: Reduce watering, ensure proper drainage.
Annual Tree Health Check
Check for signs of trouble!
Bark: Look for peeling or damage.
Leaves: Look for unusual color such as yellow or brown spots or leaves falling too early.
Growth: The tree should be upright and balanced. Note anything that looks concerning.
Pruning
Dead or broken branches can be removed. Use clean clippers to cut the branch where it attaches to the main trunk or branch, just outside of the branch collar. Prune in the winter after the growing season. See the resource section for more in-depth pruning guides.
Long-term care
If these steps are followed, your tree shouldn’t need much attention once it’s established. Once the tree is mature, an arborist can provide guidance for pruning larger branches or diagnosing any health issues. Typically, this is only needed as necessary, making it a low-frequency cost that helps ensure the long-term health and safety of your tree.
