Fall Planting Guide: Best Colorado Trees to Plant Before Snow

When folks think about Autumn yard work, most think about clean-up, about winter prep, about things that might be going dormant. And yet, for Colorado trees, fall planting is one of the best times to plant.

While spring is traditionally seen as a time for planting, trees need time to establish and build strong roots. With summer on its way, trees may struggle with heat, drought, and summer conditions that can stunt growth. If you’re looking for healthy trees, fall planting is the way to go.

Why Fall is Prime Time for Planting Trees in Colorado

Planting Colorado trees in the fall, between early September and mid-October, is one of the smartest moves you can make for long-term tree health and cost-efficiency.

The fall means warmer soils and cooler air, which give new roots the perfect conditions to grow deep before winter dormancy. This sets your trees up for stronger establishment and better spring growth.

Unlike spring planting, fall planting avoids the heat stress and rapid moisture loss of summer, reducing transplant shock and giving nursery trees a head start on establishing healthy root systems before the hot, dry season returns.

Beyond root development, fall planting offers economic and resource-saving benefits. Cooler temperatures mean less water evaporation and reduced irrigation demands. Fortunately, those temps also mean fewer active pests and lower disease pressure.

Top Reasons Colorado Trees Thrive When Planted in Fall

• Accelerated root establishment before winter dormancy
  
  
• Reduced heat stress and moisture loss compared to spring or summer planting
  
  
• Lower pest and disease pressure, boosting survivability
  
  
• Extended planting window and softer soil make it easier to work with

Factors to Consider When Choosing Colorado Trees for Fall

Plant in fall…got it. What else?

It’s no secret that Colorado’s climate varies widely. Across its geography, from the high plains to the Front Range to the mountain foothills, knowing which species works best in which place is essential.

When selecting trees for fall planting, careful planning can help ensure longevity and survivability. Not only will it reduce the chance of costly replacements down the road, but you’ll end up with a stronger, more resilient tree when it reaches maturity.

The tree selection process, for that reason, is a little bit more intensive than “We like the way that looks.” Strategic tree selection considers growth rate, sun exposure, soil type, and water availability, while also looking at the role the tree will play in your community or landscape. 

To establish healthy trees that perform well in urban and community settings, foresters and HOA teams should evaluate the following key considerations before investing in new trees:

• Growth Rate & Mature Size – Fast-growing trees provide quicker shade but may have shorter lifespans, while slower growers often offer durability and stronger structure. Consider the tree’s mature height and spread to avoid conflicts with buildings, powerlines, or sidewalks.
  
  
• Sun Requirements – Many native trees in Colorado prefer full sun, while some ornamentals or understory species thrive with partial shade. Matching the tree to its light environment is critical for survival.
  
  
• Water Needs – Drought tolerance is essential for many Colorado landscapes. Selecting drought-tolerant Colorado trees can reduce irrigation costs and water use while supporting long-term health in urban forests.
  
  
• Soil Compatibility – Colorado soils often range from clay-heavy to sandy. Work with a local tree nursery that understands regional soil challenges and can recommend species best suited to your specific site.
  
  
• Community & Environmental Role – Beyond looks, consider the tree’s shade value, air quality benefits, and whether it provides wildlife habitat or seasonal interest for residents.

The tree planting decisions you make today can maximize the ecological and financial benefits you get later, including a healthy urban canopy.

Best Colorado Trees to Plant in Fall

When it comes to Colorado trees, slower-growing species often prove to be the wisest investment. While fast-growing trees may provide quick shade, they are more prone to structural issues, disease, and shorter lifespans.

Slower-growing varieties, on the other hand, establish stronger roots, stand up better to Colorado’s variable climate, and provide lasting value for communities and homeowners alike.

Below are some of the best Colorado trees for fall planting:

Shade Trees

Slower-growing shade trees offer durability and long-lasting canopy coverage.

• Bur Oak (Quercus macrocarpa) – A tough, long-lived oak with strong wood, drought tolerance, and a broad canopy.
  
  
• American Sentry Linden (Tilia americana ‘Sentry’) – Provides dense summer shade and fragrant flowers; well-suited for lawns and community spaces.

Native Colorado Trees

Native trees are naturally adapted to Colorado’s unique conditions and require less maintenance once established.

• Gambel Oak (Quercus gambelii) – A hardy Colorado native oak that grows as a large shrub or small tree; drought-tolerant, provides fall color, and supports wildlife.
  
• Plains Cottonwood (Populus sargentii) – A historic Colorado native, slower to mature, but offers massive shade and ecological value.

Ornamental Trees

Ornamental trees bring seasonal beauty with flowers, foliage, or unique structure.

• Spring Snow Fruitless Crabapple SproutFree™ (Malus ‘Spring Snow’ sproutfree™) – Slower-growing ornamental with fragrant spring blooms and no messy fruit.
  
• Ivory Silk Japanese Tree Lilac (Syringa reticulata ‘Ivory Silk’) – Tolerates Colorado soils well and offers creamy-white summer flowers.

Drought-Tolerant Trees

Selecting drought-tolerant Colorado trees is especially important as water costs rise and climate variability increases.

• Hackberry (Celtis occidentalis) – A hardy, slower-growing shade tree that adapts to a range of soils and drought conditions.
  
  
• Kentucky Coffeetree (Gymnocladus dioicus) –  Highly resilient, drought-tolerant, and low-maintenance—excellent for large landscape projects.

Slower-growing, well-adapted species can help Colorado HOAs, communities, and city planners ensure their tree investments lead to long-lasting, healthy trees capable of withstanding Colorado’s challenging climate.

Arborist Tips for Successful Fall Planting

Certified arborists agree that fall is one of the most favorable times to plant Colorado trees. As mentioned, cooler temperatures reduce stress on new trees, while soil remains warm enough to encourage strong root development before winter sets in. This combination allows trees to establish a healthy foundation, setting them up for vigorous growth in the spring.

But planting a tree isn’t just digging a hole and putting it in the ground and crossing one’s fingers. There are some strategies to ensure its establishment and long-term success. In fact, simple things like providing a tree with enough water while it’s establishing can make a huge difference in overall survivability.

Here are a few fall planting tips from arborists:

• Choose the right tree for your site – Match growth rate, mature size, sun exposure, and water needs to your landscape. Proper tree selection reduces future maintenance, prevents overcrowding, and avoids costly tree removals.
  
  
• Prepare the soil before planting – Loosen compacted soil and amend if necessary to improve drainage and root penetration. Healthy soil is the foundation of healthy trees.
  
  
• Plant at the correct depth – Position the root flare at or just above soil level. Planting too deeply suffocates roots, while planting too shallowly can lead to instability.
  
  
• Water deeply and consistently – Even drought-tolerant trees need regular water until established. Deep watering, which is best done slowly, encourages strong, deep roots rather than shallow, weak ones. Drip irrigation allows the water to soak into the roots slowly and is a better method of watering for young trees.
  
  
• Apply mulch correctly – A 2–4 inch layer of mulch helps retain moisture, regulate soil temperature, and suppress weeds. However, it’s important to keep mulch away from the trunk to prevent rot, so stop mulching a few inches shy of the roots/trunk.
  
  
• Stake only when necessary – Staking can provide support for young trees in windy sites, but leaving stakes too long weakens natural stability. Remove them within one year.
  
  
• Monitor through winter – Newly planted trees still need occasional watering, even in the winter. Colorado’s climate can be notoriously dry during some winter months; to avoid root desiccation, check the tree and water when the soil is too dry.

With these tips, homeowners, HOAs, and city planners can encourage establishment, improve survival rates, reduce long-term costs, and enjoy healthier, more resilient Colorado trees.
