Minnesota pine trees are in trouble
Are your beautiful Norway and White Pines dying on your property? Do you want to know why and if there is a solution so it will stop happening?
We have the answer, please keep reading.
In most cases, it is as a result of multiple years of partial or full drought happening in our state between 2018 to 2024.
Drought badly damages the soil and the roots of the trees that live in that soil. Even trees that are close to a lake. A mature pine can drink up to 100 gallons a day of water from the soil during a good year. During a drought year, they get very little water if anything on a daily basis when there’s not enough water to rebuild the water table that these trees rely so desperately on. When this happens roots die back as they dry up. A mature tree needs everything it can get to maintain its water needs.
Drought stressed trees attract harmful insects, such as the pine bark beetle and other boring insects that seek out trees that are weak. Sadly, these insects can do lots of damage each year as the trees host These destructive bug families. Eventually, the trees give in and can no longer move sap from the bottom to the top and they die.
Through decades of research and work in the field of arboriculture and Tree health, Deblen has developed a unique and highly effective treatment program to address not just the insects but instead the overall health of the trees. Through nutritional support and soil regeneration we are able to help the trees recover and become healthy enough to fight insects through their own natural means. If a tree is strong, it has the ability to ward off harmful insects with its own defense system built into healthy sap. This is how trees work in nature. We do this without the use of harmful chemicals, poisons, pesticides, or any other harmful materials in order to get your strong again.
We’ve been working with the trees of Minnesota since 1967 and our knowledge has allowed us to save thousands of trees from an otherwise certain death. Put your beautiful pine trees in our capable hands so that you do not have to lose them.
