Our arborists balance plant health, safety and artistry when pruning and shaping the trees and shrubs that complement an office complex, business park or multi-unit residential area. We prune to emphasize a tree's natural shape. If the tree has structural problems, we can cable it to increase its safety. In natural disaster situations we provide priority, emergency tree damage response to our clients. We specialize in the care and maintenance of large, historic or signature trees. All of our work is performed in accordance with Industry Standard (ANSI A-300) tree pruning guidelines.
If a tree must be removed because it is dead or hazardous, our expert arborists can safely and efficiently take it down with the most advanced technical rigging equipment and experience in the industry. Our expert and careful tree removal is performed to insure safety to people, structures and the landscape. For stump removal, we have portable stump grinding equipment.
Trees add value to our landscapes in many ways. Preparing trees for construction to maintain their health and longevity with an eye toward city ordinance compliance are areas of expertise for us. If your property is about to undergo a rennovation or major construction phase and you are looking to preserve trees or protect them from construction damage, we can help.
The cure of your plant problems starts with a site visit and an accurate diagnosis by our expert Arborists. Then we custom design an insect and disease treatment program to fit the health needs of your trees (including fruit trees) and shrubs. This scientific approach eliminates unnecessary treatments by targeting only the pest-susceptible plants. By targeting only pest susceptible plants for treatment, we protect the health of your plants and the environment.
We can apply specialized treatments designed to control existing weeds and deter new weeds from encroaching into your landscape. We treat for weeds four times a year: three pre-emergent treatments before they appear and one post-emergent treatment to clean up the few weeds that elude the preventative applications.
Proper nutrition is of primary importance in plant health care. Our Soil Health Programs improve poor soils by promoting healthy soil biology and by providing plant nutrition that is 100% organic. At Collier Arbor Care, our programs feature the use of compost tea, organic fertilizers and Mycorrhizae (a beneficial root fungus) to sustainably enhance landscape soils. Our Soil Health Care and Targeted Soil Health Care programs create trees and shrubs that are healthier, more resistant to plant problems, and they look and grow better.
Urban soils, in particular, suffer over time from depletion of nutrients and need periodic replenishment. Get the most out of your landscape investment by giving trees and shrubs the proper fertilization they need to thrive.
Collier Arbor Care specializes in growing beautiful and healthy Northwest lawns. Our organic based programs provide fertilizers and nutrients based on your particular grass, growing condition, and soil analysis. We apply weed and insect treatments only if they are needed, and offer core aeration to prevent thatch build up and to allow more air, water, and nutrients to get into the root zone. We also provide soil testing and disease treatments.
Collier Arbor Care has developed a reputation within the industry for our expertise in diagnosing tough tree and landscape problems, and for designing and implementing solutions to protect your valuable landscape investment. We perform many consulting and diagnostic services including hazard tree evaluations, insect and disease diagnosis and solutions, tree protection planning and supervision for construction sites, soil analysis and fertilization recommendations, tree surveys, and tree appraisals.
