The best way to Preen Vegetable Garden Flowers for Weed Control
Preen Vegetable Garden Weed Preventer consists of corn gluten granules also known as corn gluten meal, that stop seeds from germinating in the bottom. Based on a research completed by the Iowa State University horticulture division, food-grade corn gluten meal includes an inhibitory compound that stops root development in crabgrass (Digitaria spp.), creeping bent grass (Agrostis palustris Huds.) and other weed species. Unlike pesticides or weedkillers, this organic product doesn’t contain chemicals that are harmful. Preen isn’t a weedkiller however a pre-emergence herbicide that stops weed seeds. Furthermore, the nitrogen in the corn gluten functions as a fertilizer for the garden veggies that are flowering.
