Why Fall is the Perfect Time to Plant New Trees

As the beautiful colors of fall begin to take over Oregon, many homeowners transition from thinking about the flowers in their garden to the trees in their yard. Fall is the perfect time to plant new trees, offering them the best chance to establish strong roots before winter arrives. If you’re considering adding new trees to your property this fall, here’s what you need to know.

Why Fall is the Ideal Time for Planting Trees

Fall in Oregon, particularly from late September to early November, provides the optimal conditions for planting trees. The cooler temps reduce stress on the newly planted trees, and the soil remains warm enough to encourage root growth. Fall is also when the rainy season begins, which ensures that your trees will receive plenty of natural water to help them settle in.

Choosing the Right Tree Species

Not all trees are suited for fall planting, so it's crucial to choose species that will thrive in Oregon's unique climate. 

• Douglas Fir: As Oregon's state tree, it’s well adapted to the local climate and makes an excellent addition to any landscape.
• Oregon White Oak: This native tree is not only beautiful but also supports local wildlife.
• Red Maple: Known for its stunning fall colors, the Red Maple adds a burst of color to your yard.
• Western Red Cedar: Another native option, this evergreen is perfect for creating privacy screens or windbreaks.

Preparing the Planting Site

Proper site preparation is essential for the success of your new tree.

1. Choose the Right Location: Ensure the site receives the appropriate amount of sunlight and has well-drained soil. Consider the tree's mature size to avoid planting too close to buildings or power lines – and if you’re in doubt, it’s best to consult an expert.
2. Test the Soil: Oregon soils can vary greatly, so it's wise to test your soil's pH and nutrient levels. Amend the soil if necessary to create the ideal growing environment.
3. Dig the Hole: The planting hole should be two to three times wider than the root ball, but no deeper than the root ball itself, allowing the roots to spread easily while ensuring the tree is planted at the correct depth.
4. Amend the Soil: Mix compost or well-rotted organic matter into the soil you’ve removed from the hole to enrich the soil and help retain moisture.

Planting Your Tree

Once the site is prepared, it’s time to plant your tree!

1. Position the Tree: Place the tree in the center of the hole, ensuring that the root flare (where the roots meet the trunk) is at or slightly above ground level.
2. Backfill the Hole: Begin filling the hole with the amended soil, pressing down gently as you go to remove air pockets. Be careful not to compact the soil too much, as this can hinder root growth.
3. Water Thoroughly: Once the hole is filled, water the tree deeply. This helps settle the soil and provides essential moisture to the roots.
4. Mulch: Apply a 2- to 3-inch layer of mulch around the base of the tree, keeping it a few inches away from the trunk. Mulching helps retain moisture, regulate soil temperature, and suppress weeds.

Caring for Your Newly Planted Tree

After planting, your tree will need extra care to ensure it thrives through the fall and into winter.

• Watering: Even though fall brings more rain, it’s important to water your new tree regularly until the ground freezes. Aim for deep watering to encourage roots to grow downward.
• Protection: If you live in an area prone to deer or other wildlife, consider installing a protective barrier around your tree to prevent damage.
• Monitoring: Keep an eye on your tree for signs of stress, such as yellowing leaves or wilting. Address any issues promptly to give your tree the best chance of survival.

Planting new trees is a rewarding way to enjoy your home even more, and that will pay off for years to come. By selecting the right tree species, preparing the site properly, and providing the necessary care, you’ll set your new trees up for a healthy start. As they grow, they’ll not only enhance your landscape but also contribute to the environment by providing shade, improving air quality, and supporting local wildlife. So grab your shovel and get planting this fall!
