What’s wrong with my tree? How can I make it healthy?

Design Tree Maintenance uses an integrated approach to managing insects, diseases, and environmental stresses that begins with maintaining plant health using sound cultural practices including pruning, water management, and the maintenance of healthy soils. Periodic inspections are essential to detect problems before they reach damaging levels. When treatments are necessary, Design Tree Maintenance can apply organic and naturally based materials along with vitamin based products that promote plant health while protecting people and the environment.

Tree and Shrub Diseases

Diseases are abnormalities in trees and shrubs caused by microorganisms such as fungi and bacteria and by environmental stress such as drought, temperature extremes, and air pollution. Diseases are often difficult to diagnosis as different causal agents can produce similar symptoms. Accurate diagnosis is essential to developing effective treatment programs. In the event that an on-site diagnosis and treatment method cannot be reached, Design Tree Maintenance utilizes modern diagnostic laboratories which support pest management services to ensure accurate identification and treatment of plant problems.

Top diseases that threaten or damage landscape plants in the Southwestern United States:

Phytophthora Root Rot
Cankers
Drought Stress

Damaging Insects

Hundreds of insect species damage leaves, stems, and branches; roots; and flowers and fruit of landscape plants. But not all insects on trees and shrubs are damaging. Some are beneficial and may help pollinate flowers or could be predators or parasites on insects that damage plants. Design Trees’ arborists are trained to correctly identify these beneficial insects and mites and can devise effective management programs that protect landscape plants from serious damage while conserving beneficial organisms.

 Trustindex verifies that the original source of the review is Google. We hired Design Tree to install a paver patio in our backyard. Very impressed with the outcome and would highly recommend! Beautiful work and the crew was timely and very polite. The superintendent on our job was great, unfortunately I am forgetting his name. Highly recommend this company!

 Trustindex verifies that the original source of the review is Google. My wife and I have been using Design Tree Maintenance for about 6 years now.  They've conducted both removals and long term maintenance on three large trees in our backyard.  Each visit from them has left us pleased with their work.  The process starts with a free onsite quotation (Nick always does our quotes) and on acceptance, the crew is scheduled within about a week or less.  This company is full of professionals during all stages of the process.  You can get your trees trimmed for less cost, however having trained arborists quoting and conducting the work is worth every penny.  Dago and crew always arrive ready to tackle a tough days work.  The crew uses modern safety equipment, everyone has helmets and is well trained to use their climbing, rigging, and cutting gear to get the work sorted quickly and safely.  The crew lead reviews all planned work prior to starting to ensure the quoting process has communicated everything correctly to the folks doing the laborious work.  When everything is wrapped up, the lead once again reviews the work with you to verify you're satisfied.  If you want professionals for your project, call these folks.

 Trustindex verifies that the original source of the review is Google. I have been a customer for over 10 years. Everyone in this company is professional and cares about their customers. They do our annual tree trimming and we have had them place a French drain and recently landscape the 2 courtyards at the front of the house. I cannot recommend this company highly enough. They exceed my expectations with everything they do. They are worth every penny I’ve paid them and am excited to have them landscape the remaining front yard and then the back.!
