In their natural forest environment, plants have access to every element needed for optimum health. But plants in your yard face more stressors and competition, with less naturally occurring nutrients and defenses.
With a plant health care (PHC) program, your landscape is managed holistically with routine monitoring and preventative treatments. The PHC program is comprehensive and takes the entire property into account.
Here are 5 key areas of plant health care.
