ArborPlex (14-4-5) is a liquid nutrient solution designed to promote optimum tree and shrub health. 7.05% Slow release nitrogen (half of the total N) is supplied from a urea-triazone solution, which provides consistent, extended feeding. A high quality source of phosphorus improves 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 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.

General Dilution Rate: Mix 1.25 gallons (160 oz.) of ArborPlex per 100-gallon tank. Apply 2-4 times per year or as needed.

  • 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 2 feet from the base of the tree 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: Inject one pint (16 fl. oz.) of diluted solution per injection site. Inject 4-6 inches into the soil with 1.5 foot spacing between injections.

To correct deficiencies that may occur during the season, mix 2 to 3 quarts of ArborPlex with 100 gallons of water. Spray the mixture onto the foliage until it begins to drip off. Do not foliar feed during drought conditions or when air temperature exceeds 85°F.

COMPATIBILITY: Perform a standard “jar test” to check compatibility with other products before mixing.
