Why and How to Plant Trees in September in Kansas City

If you’ve been waiting for the right time to plant trees in your yard, look no further than September. In Kansas City, this is the ideal season to give your new trees the best start possible.

And this September, we’re excited to host our Nursery Package Tree Sale at the Farm. On September 27th from 9 am to 3 pm (rain date October 4th), you can shop high-quality trees at below wholesale pricing. It’s the perfect opportunity to add beauty and shade to your property while saving big.

Why September is the Best Month for Tree Planting

Kansas City’s Climate and Seasonal Patterns

Late summer heat often stresses young trees. By September, temperatures cool down, and natural rainfall is more consistent. The soil remains warm enough to encourage rapid root growth, giving your trees a head start before winter dormancy.

Benefits of Fall Root Establishment

When trees are planted in the spring, they must quickly balance root growth with leaf, flower, and fruit development. Fall planting shifts the focus entirely to the root system. By next spring, your tree will be stronger, healthier, and ready for top growth.

Reduced Stress Compared to Summer Planting

Summer planting is often a gamble in Kansas City’s climate. With scorching days and dry spells, trees face transplant shock and higher mortality rates. September offers gentler conditions for your investment.

The Right Trees to Plant in Kansas City

Native Trees That Thrive in Missouri

Trees native to our region are naturally adapted to local weather and soils. Excellent options include:

• Bur Oak

• Eastern Redbud

• Serviceberry

• Eastern Red Cedar

Shade Trees vs. Ornamental Trees

• Shade Trees like oaks and maples provide long-term canopy and energy savings.

• Ornamental Trees such as dogwoods and crabapples bring color and seasonal beauty.

Step-by-Step Guide to Planting Trees in September

Choosing the Right Spot for Your Tree

Plan ahead for the tree’s mature size, avoiding utility lines and foundations.

Preparing the Soil for Success

Loosen compacted soil, amend with compost, and check for drainage before planting.

Proper Planting Depth and Spacing

Position the root flare at soil level. Planting too deep suffocates roots and invites disease.

Watering and Mulching Best Practices

Water deeply once or twice per week. Spread 2–3 inches of mulch, but keep it away from the trunk.

Common Mistakes to Avoid When Planting Trees

• Planting too deep or leaving the root flare buried.

• Overwatering or underwatering.

• Mulching too heavily or piling mulch against the trunk.
