What Food Should My Trees Be Getting?

Healthy plants begin with healthy soils. Fertilization is just one component of the whole equation. Adjusting soil pH and ensuring adequate organic matter is present are also key to healthy soils. For plants in urban and suburban soils, Design Tree Maintenance can simulate the optimal conditions for growth found in nature. In fact, our proprietary soil treatment process combines all the above into a single treatment to achieve this goal.

When a homeowner prefers a natural-based approach to the maintenance of their yard, we have affective solutions to manage tree and shrub health. Not only do we offer organic tree fertilizer, but naturally-based insect and disease management programs as well. This type of tree care requires a skilled and committed arborist that fully understands the needs of the landscape.

As part of our approach to tree care, regular inspections allow our arborists to identify issues early so that treatments can be timed appropriately. Timing is critical for treatments to be effective. Specific treatments include foliar application of compost teas with high beneficial bacteria and microbe counts to suppress damaging pest populations as well as pathogens and other disease. We may also prescribe the application of vitamin supplements that contain botanical oils which repel harmful insects while attracting beneficial ones.

We can also help you choose and grow healthy plants that are best suited to your landscape and demonstrate better resistance to pests and disease. Selecting the right trees and shrubs and understanding how to cultivate them with proper irrigation, mulching and soil care is the foundation for successful organic and naturally based tree care.

From the very beginning, Design Tree Maintenance has been a pioneer in the organic field, leading the way in the use of innovative practices designed to provide a beautiful landscape while maintaining a healthy environment. Our company was one of the first in the valley to originate and implement a plant healthcare program that uses alternative products and methods for control of insects and disease. This commitment to environmental stewardship is evidenced today as we continue to develop new techniques for the benefit of our customers. Our products and methods are tested by scientists at research laboratories to help ensure they are effective and safe.

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!

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.

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.!
