How to Plant Hemlock Trees


Hemlock trees are large evergreens. They can grow up to 80 feet tall with a 35-foot spread, so keep this in mind if you want to plant hemlock trees in your yard. Some hemlock trees are hardy from USDA zones 3 to 8 so they will grow in many climates around the US. Planting hemlock trees is not difficult as long as you have the room for this large and lovely tree in your yard.

Step 1

Choose a variety of hemlock tree to plant in your yard. Western hemlock only grows well in temperate rain forests like those of Western Washington, while eastern hemlock grows best in cooler climates.

Step 2

Choose a place in your yard for your hemlock tree. Hemlocks like full sun although they can also handle partial to heavy shade.

Step 3

Prepare your soil for the hemlock trees. Hemlock trees like moist, well drained soil that is either loamy or sandy. If your soil is too clay-laden, add sand and compost or manure to loosen it up and improve drainage. Work the sand and compost or manure into a depth of about 4 to 6 feet, with a 5- to 6-foot diameter.

Step 4

Plant hemlock trees in the spring to give them time to get established.

Step 5

Dig a hole for the hemlock tree. Make sure the hole is about 4 feet wide and 3-4 feet deep, enough to fit the hemlock tree's root ball.

Step 6

Place the hemlock tree in the hole. Fill the hole with soil and pat it down firmly. Water the hemlock tree right away for about 5-10 minutes.

Tips and Warnings

  • Hemlock trees need lots of water in which to thrive. Keep the soil moist but not soaking wet around the base of the trees.
