OPH Pre-Emergent™ 16-0-8 is part of Organic Plant Health’s Eco-Advantage line of fertilizers, which is used in our annual cool season turf care program. Organic Plant Health recommends a split application when it comes to broadleaf and grassy weed pre-emergent control. In other words, two separate effective applications in the spring, one in February and one in April, rather than just one heavy application in February or March. The split application is the best strategy to employ as it ensures long-lasting control that stretches into mid-summer.
As with all of our products in this line, OPH Pre-Emergent™ 16-0-8 works in several ways to improve the health of your lawn. This 3-in-1 product contains seasonally appropriate plant fertility, long-lasting pre-emergent control of crabgrass and broadleaf weeds, organic matter to feed soil microbes. This promotes healthy plant growth in the spring, a reduction in annual weed population, and a healthier, more active soil profile. At OPH we take care to ensure that all components in the bag are used to improve the conditions in your lawn.
OPH Pre-Emergent™ 16-0-8 fertilizer controls some of the most populous grassy weeds including Crabgrass, Poa annua and Goosegrass as well as broadleaf weeds like Prostrate spurge, common Purslane, Knotweed and Chickweed. For control of those and others, it is best to apply an effective POST-emergent herbicide to further control weed populations in your landscape. Organic Plant Health recommends Quincept selective herbicide.
