  • Safe to use around children and pets
  • Better for the environment than other pre-emergent crabgrass preventers 
  • Controls crabgrass, dandelions, and over 25 other weeds prior to germination
  • Provides gentle feeding and deep greening
  • Can be used in flower gardens and in planting beds
  • When to use: early spring before target weeds germinate

Jonathan Green Corn Gluten Weed Preventer plus Lawn Food feeds the lawn while preventing crabgrass, dandelions, and over 25 other broadleaf and grassy weeds. For optimal results apply early in the spring- between March and early May- before weeds germinate. For improved weed control and greening apply up to 4 times a year, in early and late spring and again in early and late fall.

The key factor in achieving great weed control results with this product is the proper timing of the first application. This weed control must be spread on established turfgrasses before the weeds germinate because it is only effective before weeds break the surface of the soil. Do not use this product when seeding because it will affect the new grass seedlings as they germinate. Based upon the organic nature of Corn Gluten Weed Preventer it may take a few seasons to control severe weed populations.

Too Soon!

I just applied this weed preventer a few days ago. Weeds haven't disappeared yet! Instructions say it could take several applications over the course of 18 months to see desired level of improvement. Ask me in Spring '26.

Corn gluten meal

In the past I have used corn gluten meal in a powder form and I was able to put it in my spreader and easily apply the product. Since these are pellets, they were to large for me to use my spreader and needed to be applied by hand. It’s to early to tell how effective the product is regarding preventing weeds and providing nourishment for the soil.

Have used this product for years and it stops weeds from emerging if the product is applied early enough. If applied both spring and fall, it seems to have a cumulative effect rendering it better each season. This is NOT a weed killer must be applied early enough to stop the weeds from even starting to appear.
