Answers to Your Top Questions About Trees and Plant Health
Why does my tree look unhealthy even though I water it regularly?
Trees can face various issues beyond water, including pests, diseases, or nutrient deficiencies. Our plant healthcare experts can diagnose the problem and recommend a tailored treatment plan.
Is it normal for my tree to lose leaves at this time of the year?
Seasonal leaf drop is normal, but if it's excessive or happens at the wrong time, it could be a sign of stress, disease, or pests. Our team can assess the situation and recommend appropriate measures.
Why are there spots on my tree's leaves?
Leaf spots can result from fungal infections or pests. Our plant healthcare services include targeted treatments to address these issues and promote your tree's overall health.
Why are the leaves on my trees turning yellow?
Leaves typically change color in Portland around mid-October. However, if you notice changes, yellowing leaves, stunted growth, and poor overall vigor, these are indicators of nutrient deficiencies and a sign that your tree is "hangry." Our experts can conduct soil tests and provide customized fertilization plans to ensure your tree gets the nutrients it needs.
Why are my tree's branches dying?
Dead or dying branches may be a result of diseases or pests. Our arborists can assess the extent of the damage and recommend pruning or other treatments to save the tree if possible.
How do I keep my trees healthy?
Our plant healthcare professionals regularly inspect plants for early signs of disease. We also offer preventive treatments to safeguard your trees from potential threats.
How much should I water my trees and shrubs?
Our experts can assess your tree's water needs based on its species and current conditions and recommend proper watering techniques to maintain optimal health.
Can you help revive a stressed tree?
Yes, our plant healthcare services include treatments to alleviate stress and promote recovery for trees affected by construction, changes in soil conditions, or other environmental stressors.
What are the signs that my shrubs need professional plant healthcare?
Look for symptoms like wilting, discoloration, unusual spots on leaves, or stunted growth. These signs may indicate underlying issues that our experts can address through specialized treatments.

Professionalism, Punctuality, Quality, Responsiveness
From my first consultation with Tillis Trees a few years ago through now, I have always appreciated Dustin and his company. I have had Tillis Trees out a few times over the years for various reasons, and every time Dustin has been knowledgeable, friendly, professional, and they do excellent work. I have had them here for tree removal, pruning, and a tree protection plan for some construction. Tillis Trees will always be my go-to arborist.

Tillis Tree Care did an amazing job for us. We had two large trees removed, many other trees pruned and a stump removed. They were on time, thorough and left our yard cleaner than they found it! Highly recommend!

We have used Tillis Tree Service for several years
Courteous and professional, knowledgeable and reasonably priced service. We have used Tillis Tree Service for several years; pruning both our street level trees and also the ones in our yard. Dustin is an excellent listener and a good communicator. Always happy with his work. Love these guys, they saved our Silk tree!

Thoughtful, detailed and very reasonable
I highly recommend Tillis Tree Care. Dustin came out for an estimate very soon after I called. He created a thoughtful, detailed and very reasonable estimate for the scope of work. The team arrived on time, did an expert job, and cleaned up after themselves. Dustin was on site and directed the work - something that has not happened with other tree services I have used in the past. I will definitely be a repeat customer.

10/10 would recommend
Great price and very professional. Crew came in and took out 3 - 100ft trees in just a few hours. They showed up on time, did a great job, and were very easy to work with. They'll be my first and only call next time. Plan on hiring them again!
