Product Description

Two Jobs in One Bag — Natural Pre-Emergent and 9-0-0 Lawn Feed

Old Cobblers Farm Corn Gluten Meal is a dual-purpose, all-natural lawn product made from 100% corn gluten meal — a natural corn byproduct. As a natural pre-emergent, it is traditionally used to help suppress germinating weed seeds such as crabgrass and dandelion when applied at the right time. As a fertilizer, its 9-0-0 analysis delivers a nitrogen boost for greener, healthier grass.

Timing is everything: apply it in early spring or early fall, before weed seeds germinate, then water in lightly to release the nitrogen. It works on seeds that are trying to sprout — it does not kill established weeds. Because it suppresses germinating seeds in general, it is not for use when you are seeding or overseeding your lawn, since it can affect the grass seed you want too.

It is a single-ingredient, corn-derived product with no synthetic chemicals added, which makes it a people- and pet-friendly choice when used as directed. Apply twice a year for ongoing feeding, and remember that weed suppression from corn gluten builds gradually with consistent seasonal use.

Where to use it: established lawns and turf where you want a natural nitrogen feed plus pre-germination weed suppression — not on areas you are about to seed or overseed.

Key Benefits

• Dual-Purpose: A natural pre-emergent for germinating weed seeds and a 9-0-0 nitrogen feed in one product.

• Natural Nitrogen Boost: 9% organic, slow-release nitrogen for greener, healthier grass.

• Single Ingredient: 100% corn gluten meal — a natural corn byproduct, no synthetic chemicals added.

• Pet- & People-Friendly: A corn-derived product that is friendly to use around the family when applied as directed.

• Adds Organic Matter: Breaks down to add organic matter that supports long-term lawn health.

• Timing-Based Suppression: Targets germinating weed seeds when applied before they sprout.

• Easy to Apply: Spreads easily with a broadcast spreader; water in to activate.

Best Uses

• Established lawns and turf (not newly seeded areas)

• Early-spring crabgrass-germination window

• Early-fall weed-germination window

• Lawns wanting a natural nitrogen feed

• Homeowners preferring a corn-derived, single-ingredient product

• Seasonal lawn-care programs (twice per year)

Important Notes / Safety

• Timing Is Critical: Apply before weed seeds germinate — early spring or early fall. Applied late, it acts mainly as a nitrogen feed.

• Do NOT Use When Seeding: Corn gluten suppresses germinating seeds in general, so do not apply when seeding or overseeding — it can inhibit your desirable grass seed too. Wait about 6 weeks after seeding.

• It Won’t Kill Existing Weeds: This is a pre-emergent — it targets sprouting seeds, not established weeds.

• Water In to Activate: Apply in dry conditions, then water in lightly to release the nitrogen.

• Suppression Builds Over Time: Weed suppression from corn gluten develops gradually with consistent seasonal use.

• Storage: Store in a cool, dry place. Keep sealed and away from children and pets.

Application Instructions

-Lawns: 15 lbs per 1,500 sq ft (about 10 lbs / 1,000 sq ft; ~436 lbs / acre)
-Timing: early spring or early fall, in dry conditions, before weed seeds germinate
-Activation: water in lightly after applying to release the nitrogen
-Frequency: twice per year; suppression builds with consistent seasonal use
Step by step
1. Apply in early spring or early fall, in dry conditions, before weed seeds germinate.
2. Spread 15 lbs per 1,500 sq ft (about 10 lbs / 1,000 sq ft) evenly with a broadcast spreader.
3. Water in lightly after applying to activate the nitrogen.
4. Do NOT apply when seeding or overseeding — it can inhibit desirable grass seed too.
5. Reapply twice per year for ongoing feeding and pre-germination suppression.
6. Remember it targets germinating seeds, not established weeds.
What not to do
Do not apply when seeding or overseeding (it can inhibit your grass seed too), do not expect it to kill established weeds, and do not apply outside the pre-germination window if weed suppression is the goal.
