ArborPlex (14-4-5) is a liquid nutrient solution formulated with slow release nitrogen, high quality phosphorus and potassium as well as micronutrients. It is designed to promote optimum tree and shrub health.
ArborPlex contains 7.05% slow release nitrogen (half of the total N), from a urea-triazone solution, which provides consistent, extended feeding. A high quality source of phosphorus improves it’s availability within the soil to enhance root development. Potassium is supplied as potassium hydroxide (KOH), providing higher solubility and low salt index. ArborPlex also contains fully chelated micronutrients to enhance color and relieve deficiency symptoms.
ArborPlex (14-4-5) is the foundation of the Arbor Rx program – a Prescriptive Fertilization and Soil Enhancement Program designed to maximize tree and shrub health by combining plant nutrition with products to enhance soil quality, stimulate root growth and improve water availability. Learn more.

ArborPlex can be applied through soil drench, root injection or foliar feeding. It may be
applied alone or tank mixed with other products. Shake well before using.
Dilution Rate: Mix 1.25 gallons (160 oz.) of ArborPlex per 100-gallon tank. Apply 2-4 times
per year or as needed.
Operating pressure: 150 – 200 lbs PSI or ½ gal per 4 seconds
Trees: Apply 50 gallons of solution per 1,000 sq. ft. Inject 4-8 inches into the soil where the feeder roots typically occur. Begin injections 1-3 feet out from the trunk to avoid injury
to large roots and work in a grid pattern away from the tree to within 2 feet of the drip
line. Apply 1 pint (16 fl. oz.) of diluted solution per injection site at 18 inch spacing or ½
gallon (64 fl. oz.) of diluted solution per injection site at 3 foot spacing.
Shrubs: Apply 50 gallons of solution per 1,000 sq. ft. Inject one pint (16 fl. oz.) of diluted
solution per injection site. Inject 4-6 inches into the soil with 18 inch spacing between
DBH Method: Use the chart below to determine the volume of diluted solution to apply per
inch of trunk diameter at breast height (DBH).
