What Makes It Pro-Grade?

Core 24-6-12 lawn fertilizer comparison image

Small Particle Size

Standard consumer fertilizer granules are 60% bigger than the size of Core 24-6-12 granules. The pros prefer formulas with smaller particles because it provides more complete and uniform coverage, which boosts the product’s effectiveness.

When to Apply Core 24-6-12

This all-purpose fertilizer can be applied to all turf types any time it is actively growing. It contains a combination of quick- and slow-release nitrogen for both immediate and extended feeding. Core 24-6-12 feeds for up to 8 weeks and can be reapplied at 6-8 week intervals.

Pro Tips for Best Results

Check The Forecast

Avoid applying before heavy rainfall so particles don't get washed away.

Mow First

Clear any lawn debris and make it easier for particles to reach the soil.

Clean Up

Sweep or blow product off the driveways/sidewalks back into the lawn.

Water Deep

Your lawn will need at least 0.2 inches of water.

Spreader Settings

We recommend using a broadcast spreader. These spreader settings are a guide. Many variables such as walking speed, terrain, particle size, density, and spreader condition can affect these settings. Be sure to calibrate your spreader before every application.

Q&A

Can I apply 24-6-12 early in the morning when Dew is heavy on the yard and that be enough without watering some more?: No. You will need to apply Core 24-6-12 to a dry lawn, and water in at least .2 inches.
After applying Core 24-6-12 how long should you wait before applying Green Shocker Thanks Roger: Green Shocker may be applied 14 days after a previous fertilizer application.
I just applied Core 24-6-12 how long should I wait to apply Green Shocker?: Green Shocker may be applied 14 days after a previous fertilizer application.
Do I need to water even if I applied weed and feed after a dew fall early in the morning?: Weed & Feed should be applied to wet grass. If the Weed & Feed is able to stick to the grass blades from dew, it will be effective. If the product is not sticking, it is best to water the lawn first or wait to apply after a rainfall.
Is it ok to apply core 24-6-12 after weed and feed?: It is recommended to wait at least 30 days after applying Weed & Feed to apply fertilizer.
