As a homeowner or property owner in Denver, you want a polished yard with healthy shrubs that add long-term value. Denver’s intense UV exposure, rapid spring growth, temperature swings, and alkaline, clay-heavy soils can affect shrub health and care needs. American Arbor Care, a trusted family-owned company since 1995, provides expert bush trimming services with certified arborists who know how to shape different shrub types properly to promote healthy growth and boost curb appeal. Proper trimming not only enhances appearance but also prepares your shrubs to thrive in Denver’s unique landscape conditions.
While many people assume trimming and pruning mean the same thing, they are actually two different services that achieve unique goals for your shrubs and bushes.
- Shrub Trimming
Trimming focuses on maintaining the shrub’s desired shape and overall appearance. When we trim, we typically use power hedge trimmers or shears to skim the tops and sides of shrubs to help keep them in top shape. This creates a clean, uniform, manicured look that is great for hedges, border plants, and formal landscapes. Regular bush trimming is part of regular maintenance and helps produce well maintained bushes; most shrubs need trimming at least once a year. - Shrub Pruning
Pruning a shrub involves removing dead, dying, or diseased branches using selective, targeted cuts. We use hand pruners to cut at specific branch junctions, which is much different than the trimming technique of skimming the surface of the shrub. Pruning promotes healthy new growth by improving air circulation throughout the plant, and it plays an important role in extending the life the plant. The timing of pruning is critical to its success. If you prune at the wrong time of the season, you could overly stress the plant or remove next year’s flower buds.
If you want your shrubs to thrive, hire an expert to handle the shrub trimming and pruning. American Arbor Care provides a full range of shrub-care support, with bush trimming as part of broader lawn care and landscape upkeep in Denver. There are a lot of landscaping challenges in Denver, and you want someone on hand who knows how to meet the challenges and keep your shrubs healthy year after year.
For example, Denver’s high altitude means we experience intense levels of UV rays. This accelerates growth during the spring and summer months, and Denver’s climate can change shrub growth patterns quickly, making proper timing important. A shrub that looks tidy at the beginning of the growing season can quickly become overgrown. Summer in Denver is over all too soon, and we can experience early fall freezes (as well as late spring frosts) which can leave shrubs with freeze-damaged branches. These need to be removed at the right times to allow healthy regrowth.
Denver’s soil types are also a challenge to local homeowners. We are known for alkaline, clay-heavy soils, and these soil conditions can affect plant health in ways that make shrubs more vulnerable to disease. If they are improperly trimmed or pruned at the wrong time of year, the stress multiplies, making it difficult for your shrubs to thrive.
One of the things we love about Denver’s neighborhoods is the variety of flowering shrubs, evergreen bushes, and ornamental hedges that can be found on residential and commercial properties. Each shrub type has different growth patterns and timing needs. If you cut at the wrong time or prune too aggressively, you could remove next season’s blooms or permanently damage the plant’s structure. Moreover, you could create entry points for pests and disease.
American Arbor Care offers comprehensive trimming and pruning services for a wide range of shrubs, bushes, hedges, and ornamental plants. We approach every job with arborist-level knowledge that cares for the whole plant, not just cosmetic shaping.
Hedge & Border Shrub Trimming
Our hedge and border shrub trimming service includes:
- Precision shaping of hedges and border shrubs
- Regular trimming schedules tailored to growth rate and species
- Clean-up of all trimmings and debris after each visit
Your hedges and border shrubs will look clean and consistent under our care. Even after the first trimming, you will notice hedge trimming boosts curb appeal and improves the overall appearance of your outdoor space. Throughout the growing season, you can expect full, dense, and uniform hedges with no overgrowth blocking your walkways, block windows, or sight lines. If you have a fast-growing shrub, like privet, we will ensure it gets more frequent attention than a slower-growing shrub, like boxwood. Quote amounts can vary based on shrub size and accessibility issues.
Ornamental Bush & Flowering Shrub Pruning
Pruning ornamental bushes and flowering shrubs includes:
- Selective hand pruning of dead or weak branches, or branches that are crossing each other
- Spring-flowering shrubs (like lilac and forsythia) are pruned right after they bloom, because proper timing helps protect next season’s buds
- Summer-flowering shrubs are pruned in late winter or early spring
Use of thinning cuts to open up the canopy and improve airflow and sunlight penetration in dense shrubs
Getting the timing right is key for pruning services. Our arborist expertise helps us maximize blooming year after year by preserving the flower buds. We also strive to extend the lifespan of ornamental plants that would otherwise become overgrown and woody. Proper pruning also supports fuller growth and a natural form that is wider at the bottom than the top for better light access. You can depend on us to employ proper pruning techniques to improve plant structure and reduce the risk of storm damage to top-heavy branches. After pruning, shrubs may also need deep watering during extended dry periods to support recovery.
Evergreen & Conifer Shrub Trimming
Denver abounds with junipers, arborvitae, and spruce shrubs, and we have the evergreen and conifer shrub trimming services to care for them. Our services include:
- Careful trimming of evergreen shrubs
- Correct timing of the trimming (typically late spring, after the new growth has hardened off)
- Shaping of the shrub to maintain a natural, proportionate appearance that does not look over-sheared
Unlike deciduous shrubs, many conifers cannot regenerate growth from bare wood, so cuts must be made into green, live tissue. Our arborists will handle these trimming jobs with precise care, maintaining year-round visual appeal. We keep evergreen shrubs looking full and healthy without creating bare patches, and we protect the plant’s structure against harsh winter weather.
Overgrown Shrub Restoration
If your shrubs have become overgrown or neglected, rely on us for restoration services, which include:
- Assessment of each shrub by a certified arborist who will determine whether it will require restoration or replacement
- A restoration plan that accounts for several factors, including species, age, and condition, before deciding whether pruning or replacement is best
- A phased pruning plan to gradually bring overgrown shrubs back to a healthy size and shape over one or two growing seasons to support plant health without cutting more than the shrub can handle at once
If your overgrown shrub can be revived with proper care, you can save the cost of a full shrub replacement. We know that using a single, aggressive cut to a neglected shrub could kill it, which is why our shrub restoration services are not a one-time fix. Some shrubs, such as spirea, can tolerate very hard cutbacks in the right situation, including removal of up to 90% of growth. We restore overgrown landscapes to a clean, manageable condition with long-term plans.
Because timing is so crucial when trimming shrubs, it’s important to know the timeframe for specific types of shrubs and bushes, since the right schedule depends on the shrub type and its flowering habit. Here are the guidelines we follow here in Denver:
- Spring-flowering shrubs , such as lilac, forsythia, and viburnum, should be pruned right after they finish blooming, typically late spring. Pruning earlier removes flower buds that formed the previous fall.
- Summer-flowering shrubs such as potentilla, spirea, and rose of Sharon, are best trimmed in late winter or early spring during the dormant season; the best time to prune most landscape shrubs is during that window to encourage vigorous growth, and many deciduous shrubs benefit from trimming in March-April before growth starts.
- General maintenance trimming for hedges and border shrubs can be done throughout the growing season (April through October) as needed to maintain shape, but avoid cutting in the wrong seasonal window if bloom production is a priority.
- Avoid heavy pruning in late summer or early fall because it can stimulate new growth that will not harden off before the first frost.
The arborists at American Arbor Care assess each property’s specific plant mix and recommend a trimming calendar that is tailored to those varieties and your personal landscaping goals.

u003cstrong style=u0022font-size: 20px;u0022u003eSoil u0026amp; Root Health Treatmentsu003c/strongu003ernWe strive to provide you with the soil and root health treatments that you’ll benefit the most from. We highly recommend annual aeration to allow oxygen and water to reach the roots of compacted clay soil, and when combined with overseeding, it delivers outstanding results for both turf and root health. Amending heavy clay soils with organic compost improves drainage, aeration, and nutrient availability for optimal plant health care. Our services include deep root watering, which is essential in the Colorado climate, and drip irrigation systems that deliver water directly to the root zone, minimizing evaporation and loss. Soaking roots every 3 to 4 weeks helps prevent fatal winter root desiccation in vulnerable plants. Growth regulator soil treatment improves drought resistance, reduces excessive growth, and enhances root density. We also recommend applying 2–4 inches of organic mulch to reduce evaporation and keep soil cool, but always keep mulch 6 inches away from tree and shrub trunks to prevent rot and bark disease.rnrnu003cstrong style=u0022font-size: 20px;u0022u003eFertilization u0026amp; Nutrient Managementu003c/strongu003ernOne of the best ways to maintain your greenery is through proper plant health care, which includes essential cultural practices such as fertilizing. Fertilizing is a key component that supports plant vitality by providing necessary nutrients for growth and resilience. Regular fertilization, as part of a broader set of cultural practices like pruning, watering, and soil management, helps maintain the health and vigor of your landscape. This might mean slow-released spring fertilization and fall fertilization for long-term nutrient support. You can try iron chlorosis trunk injections for nutrient-deficient trees, which supply iron and manganese.rnrnu003cstrong style=u0022font-size: 20px;u0022u003ePreventive u0026amp; Seasonal Treatmentsu003c/strongu003ernWinter protection for evergreens includes anti-desiccant sprays, while winter watering is a crucial preventative treatment for trees, shrubs, and perennials between November and March if precipitation is low. Consistent plant health care practices, such as routine monitoring and timely interventions, help address environmental stresses throughout the year. Seasonal timing and proactive care can make a significant difference in the appearance and vitality of your property.
Developing a customized plant health care (PHC) program requires a thorough understanding of your landscape, your goals, and ongoing collaboration between you and our certified arborist. Our approach to plant care programs is to tailor them to your specific needs by first providing an on-site evaluation and walking your property to create the right custom treatment plan. Effective plant health care programs typically include routine monitoring, preventive treatments, and a strong working relationship between the arborist and the property owner to ensure optimal results. After the treatments, our team continues with ongoing monitoring and adjustments, always guided by science-based decisions and a long-term plant health focus.
