Planting the right tree in the right place is one of the most impactful investments you can make for your Longmont property. Our arborists help you select species that thrive in Longmont's alkaline clay soils and USDA Zone 5b climate, then handle proper planting, staking, and establishment care to give your new tree the strongest possible start.
Too many Longmont homeowners plant species that struggle in our high-pH soils and semi-arid climate. Red maples turn chlorotic. Bradford pears split in wind. And fast-growing trees like silver maple create expensive maintenance problems within a decade. We guide you toward proven performers for Longmont conditions and plant them with techniques that promote deep root development and long-term health.

Our arborists evaluate your site conditions including soil pH, sun exposure, available space, and drainage patterns to recommend species proven to thrive in Longmont. We match your aesthetic goals with trees that will perform for decades without chronic problems.
Proper planting depth, root flare exposure, and backfill technique are critical for establishment in Longmont's clay soils. We plant at the correct depth, amend backfill as needed, and mulch properly to promote healthy root development.
New trees need structured watering, staking where appropriate, and monitoring during their first two growing seasons. We provide establishment care plans tailored to the species planted and the specific conditions on your Longmont property.

While our home base is Longmont, our tree care crews serve communities throughout Boulder County and the northern Front Range. From the established neighborhoods of Boulder and Lafayette to the growing communities of Erie and Berthoud, we bring the same licensed, insured, and ISA-certified expertise to every property we work on. The tree species, soil conditions, and climate challenges across these communities are similar to what we see daily in Longmont, which means our local knowledge translates directly to quality results wherever we work.
Frequently Asked Questions
Tree Service can be complex, and weโre here to provide answers to common questions. Here are some frequently asked questions from our clients.
Tree trimming costs in Longmont typically range from $200 to $1,800 depending on the tree species, height, number of branches requiring work, and accessibility. Cottonwoods and mature elms along the St. Vrain corridor often fall on the higher end due to their size. We provide free on-site estimates so you know exactly what to expect before any work begins.
Longmont requires all tree contractors performing work aloft to hold a City of Longmont Tree Contractor License under Municipal Code Chapter 6.88. Licensed contractors must carry $1,000,000 in general liability insurance and employ at least one ISA Certified Arborist. Always ask for proof of licensing before hiring anyone to work on your trees.
The best time to trim most trees in Longmont is during late fall through early spring while they are dormant. This reduces stress on the tree and minimizes disease transmission risk. However, dead or hazardous branches should be removed immediately regardless of season. Spring-flowering trees like crabapples are best pruned right after they bloom.
Signs your tree may need removal include large dead branches in the crown, significant trunk decay or cavities, visible fungal growth at the base, severe lean that has changed recently, root heaving, and major structural cracks. If more than 50 percent of the crown is dead or damaged, removal is usually more practical than attempting to save the tree.
Emerald ash borer was confirmed in Longmont in 2016 and now threatens every ash tree in the city. Treatment with trunk injection is most effective when started before significant canopy loss occurs. The City of Longmont Forestry Services maintains a public ash tree map and encourages private property owners to consult with a licensed tree contractor about treatment options.
After the 2021 Marshall Fire destroyed over 1,100 homes in Boulder County, wildfire mitigation became essential for properties near the foothills. Creating defensible space involves thinning trees, removing ladder fuels, and maintaining clearance zones around structures. Boulder County homeowners may qualify for 50 percent cost sharing through the Wildfire Partners program.
Longmont sits in USDA Hardiness Zone 5b with alkaline clay soils, which limits species options. Excellent choices include bur oak, Kentucky coffeetree, honeylocust, hackberry, and several crabapple varieties. Native species like narrowleaf cottonwood and Rocky Mountain juniper thrive here. We avoid species prone to iron chlorosis in high-pH soils like red maple and pin oak.
Fall planting between September and mid-October is ideal in Longmont because it gives roots time to establish before winter dormancy while avoiding summer heat stress. Spring planting works well from April through May after the last hard freeze. Avoid planting during Longmont's hot dry summer months when newly planted trees struggle to maintain adequate moisture.
Trees on your private property do not require city approval. However, planting in the city right-of-way between the sidewalk and street requires prior approval from Longmont Forestry Services through a ServiceWorks request. Planting without approval in public right-of-way may result in the city requiring removal. Our team handles the approval process for right-of-way plantings.
Water deeply twice per week during the first growing season and once weekly during the second year. Longmont's semi-arid climate means supplemental watering is essential even during fall and winter when the ground is not frozen. Apply three to four inches of wood chip mulch around the base but keep it away from the trunk. Avoid fertilizing during the first year while roots establish.

We hired them to treat our two large ash trees for emerald ash borer. They explained the treatment process clearly, answered all our questions, and followed up to check on the trees afterward. Very knowledgeable and honest about what our trees actually needed.

Called for emergency service after a wind event dropped a huge branch across our driveway. They responded the same day and had everything cleared within a couple hours. Fair price, great crew, and they even gave us recommendations for preventing future issues.
