Mixing by the bucket

There are two honest ways to get BioS+ out of the bottle and into the yard, and the label blesses both.

The first is the BioSiphon — BioTurf's hose-end sprayer. Thread any garden hose onto it, check the straw is seated, and rinse the area first with plain water at medium pressure. Then turn the knob: the sprayer meters concentrate into the stream on its own, no math required. When you're done, the bottle and sprayer store as-is and refill from the gallon jugs.

The second is the pump sprayer, for balconies, corners and indoor work: mix one to four ounces of concentrate per gallon of water. One ounce is maintenance strength; four is for the corner that has been telling on the dog since last summer. The same diluted mix handles indoor carpet, tile and the region around a cat's litter box.

Whichever route you take, the aftercare is identical: keep the treated area wet for as long as possible, because damp enzymes are working enzymes. And put the next treatment on the calendar — every two to four weeks, sooner for the busy runs.
