  • Petrik products work best with DE-CHLORINATED WATER. Use tank water. If using town water, simply let the water sit in an open container overnight to allow chlorine to evaporate before adding Petrik products.
  • If using a sprayer, keep nozzle on wide low-pressure setting.
  • If applying directly to young roots, do not wash soil away during application.
