Maintenance

Professional Tree Maintenance Services in San Luis Obispo County

Trees are among the most valuable features on a property — they provide shade, beauty, and long-term value. But without proper maintenance, even the strongest trees can become hazardous or decline prematurely. At 4th Generation Tree (4G Tree), we provide expert tree pruning, trimming, disease management, pest control, fertilization, and seasonal care throughout San Luis Obispo County, including Paso Robles, Atascadero, Templeton, San Luis Obispo, Arroyo Grande, Morro Bay, and surrounding communities.

As an ISA Certified Arborist (WE-12338A) and fully licensed contractor (CA License #906700, QAL #168666), we offer science-based tree care that ensures safety, health, and long-term tree longevity.

Tree Pruning & Trimming Services

Regular pruning is one of the most important aspects of tree maintenance. Our team uses modern arborist practices to improve tree structure and reduce risks.

• Deadwood Removal – Safely removes dead or decaying limbs that could fall during storms.
• Crown Reduction – Reduces overall size while maintaining natural shape (a safer alternative to topping).
• Crown Thinning – Improves airflow, sunlight penetration, and reduces wind resistance.
• Structural Pruning – Corrects weak branch attachments to strengthen young and mature trees.

Whether you have a heritage oak in Atascadero, fruit trees in Templeton, or landscaping trees in Paso Robles, our pruning services are designed to keep them safe, attractive, and healthy.

Seasonal Tree Maintenance on the Central Coast

San Luis Obispo County’s diverse climate creates unique challenges for trees:

• Paso Robles & North County – Long, hot summers often stress oaks and fruit trees, making proper watering, mulching, and pruning essential.
• Coastal Areas (Morro Bay, Cayucos, Cambria) – Higher humidity encourages fungal leaf spot, mildew, and pest issues.
• San Luis Obispo & Arroyo Grande – A mix of urban growth and older trees creates risk from falling branches near homes, businesses, and power lines.

We provide seasonal maintenance plans tailored to your property, ensuring trees thrive year-round despite changing weather conditions.

Disease Management & Tree Health Care

Trees can be affected by fungal infections, bacterial blights, and environmental stress. Left untreated, these issues can spread quickly and lead to decline.

Common local problems include:

• Oak wilt & sudden oak death (impacting native oaks)
• Fire blight (affecting pear and apple trees)
• Anthracnose & leaf spot diseases (common in coastal climates)

Our team can diagnose and treat tree diseases early, helping prevent further spread and preserving the long-term health of your landscape.

Pest Control for Trees

Pests are one of the leading causes of tree decline in San Luis Obispo County. Our Qualified Applicator License (#168666) allows us to safely and legally treat trees for insect infestations.

We manage common Central Coast pests such as:

• Boring beetles & bark beetles (often fatal to drought-stressed pines and oaks)
• Scale insects (common on palms and fruit trees)
• Gypsy moth & caterpillars (defoliating pests that weaken trees)

We use targeted, environmentally responsible treatments to protect your trees and minimize long-term damage.

Fertilization & Soil Care

Healthy trees start with healthy soil. Over time, soil can become compacted or depleted of nutrients, leaving trees vulnerable. Our fertilization services are customized to each tree species and soil condition.

• Improves growth and foliage color
• Strengthens resistance against disease and pests
• Supports fruit and flower production
• Enhances overall tree resilience during drought

We also recommend pairing fertilization with mulch application. Our partner company, Arbor Mulch, provides high-quality colored mulch and natural wood products to improve soil moisture retention and enhance landscape appearance.

Emergency Tree Services & Risk Reduction

Storms, drought, and aging trees can create sudden hazards. A fallen limb or unstable tree is not just inconvenient — it can threaten property and safety.

Our team provides:

• 24/7 emergency tree response
• Storm damage cleanup
• Hazard assessments for leaning, cracked, or unstable trees

We also work with insurance companies, HOAs, and municipalities to provide documented safety reports and professional risk reduction services.
