Growth regulator to promote tree health

Excavation severs tree roots and heavy equipment has compacted soil in critical root zone

In certain cases, a properly applied growth regulator can help keep your trees healthy. Growth regulator application reduces tree growth for up to three years. By limiting the energy trees put into new growth, they are able to store more energy which is needed to leaf out each spring. Trees may also appear healthier and greener as new leaves are slightly smaller and have more chlorophyll concentrated in them. The change in leaf structure may also increase drought and disease resistance. Beneath the ground, trees develop more fine absorbing roots, increasing their ability to absorb water and nutrients.  

Growth regulator is a chemical compound that affects the growth and development of plants.  When plants produce these compounds themselves they are known as plant hormones. Paclobutrazol is a growth regulator that reduces the growth of trees by blocking gibberellic acid, a plant hormone responsible for the elongation of plant cells. The main use for growth regulators is to preserve declining trees or trees that have had construction damage to their root systems. More information about construction damage can be found here. https://www.shadywoodtreeexperts.com/blog/the-impact-of-construction-on-your-trees-health

A home is going to be built on this empty lot and we treated this oak tree with growth regulator to reduce the impact of construction. This is the trench method of applying product

Additional things you can do to maintain the health of your trees

Water trees regularly using a hose or lawn sprinkler for at least an hour every one to two weeks whenever there is not adequate rainfall. Mulch root systems when possible, using natural wood chips to protect the trunk, condition and improve the soil, and to conserve soil moisture.  If you see anything that doesn’t look right, have your trees inspected by one of Shadywood Tree Experts International Society of Arboriculture Certified Arborists.
