Is there a shelf life for Scotts weed and Feed?

Scotts weed and feed products are popular lawn care items designed to eliminate weeds while also fertilizing grass. Like most lawn care chemicals, Scotts weed and feed has a limited shelf life. Understanding the shelf life and proper storage of Scotts weed and feed can help homeowners get the most out of their investment in these products.

What is the shelf life of Scotts weed and feed?

Most Scotts weed and feed products have a shelf life of about 2-3 years when stored properly. This shelf life applies to both liquid and granular formulations. The active ingredients in weed and feed products can break down over time when exposed to heat, moisture, or sunlight. Using weed and feed beyond its intended shelf life will result in a less effective product.

Here are the typical shelf lives for common Scotts weed and feed products:

Product Shelf Life
Scotts Turf Builder Weed & Feed 2 years
Scotts Turf Builder Weed & Feed with Crabgrass Preventer 2 years
Scotts Starter Food for New Grass Plus Weed Preventer 3 years
Scotts Weed B Gon Plus Crabgrass Control 2 years

As these examples demonstrate, most Scotts weed and feed formulations stay effective for around 2-3 years from the production date before quality degrades. The product packaging will indicate an expiration date to help determine when the shelf life has been reached.

How to store Scotts weed and feed to maximize shelf life

Proper storage is key to getting the most out of your Scotts weed and feed before expiration. Here are some storage tips:

  • Keep bags and containers tightly sealed when not in use.
  • Store in a cool, dry place away from excess heat, moisture, and direct sunlight.
  • Avoid storage in hot places like garages or garden sheds.
  • Keep away from children and pets.
  • Do not allow product to freeze.
  • Store in original packaging until ready to use.

Follow the directions on the product packaging for ideal storage. Granular and liquid formulations often have slightly different requirements. Storing Scotts weed and feed properly prevents the active ingredients from breaking down prematurely.

Signs that Scotts weed and feed is past its shelf life

Here are some signs that your Scotts weed and feed may be expired or past its prime:

  • The product doesn’t seem to be working effectively when applied.
  • Weed control seems poor and fertilizer effects diminished.
  • The chemicals have a rancid smell instead of their normal odor.
  • There is lumpiness or caking of granules.
  • Liquid formulations appear cloudy or separated.
  • Your lawn shows unexpected discoloration after application.
  • You notice reduced grass growth and poor lawn quality after use.

If your Scotts weed and feed product shows these degradation signs, it likely won’t work as intended. When a product is beyond its shelf life, the chemicals break down to the point of being less effective. Applying degraded Scotts weed and feed will not kill weeds properly or fertilize grass effectively.

Buying Scotts weed and feed near expiration dates

When purchasing Scotts weed and feed, check the expiration date on the packaging. It’s best to select products with at least one growing season of shelf life remaining. This avoids buying weed and feed that might expire before you can use all of it.

If you happen to get Scotts weed and feed products that are near expiration at a bargain price, try to use them right away during the current growing season. Applying shortly after purchase maximizes the remaining effectiveness. Storing an already nearly expired product likely means it will stay usable for an even shorter time.

Properly disposing of expired Scotts weed and feed

Outdated Scotts weed and feed should be disposed of properly to avoid environmental contamination. Here are some safe disposal methods:

  • Use up any remainder during the current season even if expired.
  • Save any unused product to bring to a household hazardous waste collection event.
  • Contact your local waste agency to ask about safe disposal options in your area.
  • Wrap original containers in plastic bags to minimize leakage before putting in the trash.
  • Do not pour leftover liquid formulations down drains or into waterways.

Disposing of Scotts weed and feed carefully prevents the chemicals from entering groundwater or polluting the local landscape. Check local hazardous waste regulations for the most environmentally friendly ways to dispose of lawn chemicals in your municipality.

Alternatives to use up expired Scotts weed and feed

If you have extra expired Scotts weed and feed on hand, there are some alternative uses that can help use it up safely:

  • Spot treat any visible weeds to avoid waste.
  • Do a perimeter or spot application around gardens and landscaping.
  • Use near hardscapes like driveways and patios where weeds often grow.
  • Apply along fence lines and property boundaries to maintain neat edges.
  • Use around mailboxes, lamp posts, and utility equipment prone to weeds.
  • Sprinkle lightly when overseeding to get added weed prevention.

While results won’t be ideal for large-scale lawn care, these targeted applications can provide some benefit until you can purchase fresh Scotts weed and feed. Prioritize areas most prone to weeds when using up expired products.

Does Scotts weed and feed expire if never opened?

Unopened Scotts weed and feed lasts longer than opened containers, but it still has a finite shelf life. The active ingredients eventually degrade with time regardless of whether exposure to air and moisture occurs. Storage conditions also impact shelf life.

An unopened bag or bottle has up to the manufacturer’s recommended shelf life when appropriately stored. This is typically 2-3 years after the production date. Leaving Scotts weed and feed completely sealed delays breakdown but does not make the product last indefinitely.

Check expiration dates on unopened packages, and avoid using any that are more than a few years old for best performance. Opening very outdated weed and feed means dealing with chemicals already in an advanced state of deterioration.

Does heat affect Scotts weed and feed effectiveness?

Excess heat can shorten the shelf life and reduce effectiveness of Scotts weed and feed products. Storage in hot places causes the chemicals to break down faster. Applying Scotts weed and feed during hot weather can also lessen results.

The ideal storage temperature for Scotts weed and feed is around 75°F or cooler. Temperatures above 90°F significantly accelerate deterioration. Leaving bags or containers in non-climate controlled sheds or garages invites heat exposure.

Spreading Scotts weed and feed on hot sunny days, especially above 85°F, causes rapid evaporation and chemical degradation. For best lawn absorption and weed control, apply during the cooler temperatures of early morning or late afternoon.

How to determine the production date on Scotts weed and feed

Checking batch dates and production codes on Scotts weed and feed packaging allows you to determine the approximate age of your purchased products. This helps identify items nearing expiration so you can use them first.

Look near the barcode or expiration date for a batch or lot number. This typically appears as a letter and series of numbers like A304-500. The first one or two digits refer to the production year while the remaining numbers are for Scotts internal tracing only.

For example, a batch code of C522-303 would indicate a production year of 2022. This weed and feed would then be good for about two more years after purchase before expiring in 2024.

Being able to decode the production date helps choose the oldest Scotts weed and feed first and ensures properly timed usage.

Frequently Asked Questions

Does humidity affect Scotts weed and feed shelf life?

Yes, humidity and moisture can shorten the shelf life of Scotts weed and feed. Exposure to moisture causes the chemicals to dissolve and degrade more rapidly. Storing weed and feed in humid environments or allowing bags to get wet accelerates deterioration.

Can you use Scotts weed and feed after expiration?

It’s not recommended to use Scotts weed and feed beyond the expiration date. Chemical degradation means the product won’t work as intended. Weed control and fertilization will be poor, and grass could show damage from ineffective application.

How long does liquid Scotts weed and feed last when mixed?

Once mixed as directed for application, liquid Scotts weed and feed typically lasts around 8 hours. You want to avoid storing mixed liquids for longer than a single day. The chemicals begin deteriorating immediately upon dilution.

Does Scotts weed and feed go bad if frozen?

Freezing can cause Scotts weed and feed products to crystallize or clump together, significantly impacting the shelf life. Chemical activity declines once frozen. Let any accidentally frozen product completely thaw before assessing its condition.

Can you reuse an opened bag of Scotts weed and feed?

Open bags of Scotts weed and feed can be resealed and stored for later use within the standard 2-3 year shelf life. Try to press out excess air before resealing to minimize moisture exposure. Use the opened product first before unopened ones.

Conclusion

Understanding the shelf life and proper storage of Scotts weed and feed allows you to maximize the value of your purchase. Most formulations are effective for 2-3 years when kept in a cool, dry place. Look for signs of deterioration like clumping, poor performance, and discoloration to identify expired products. Dispose of Scotts weed and feed carefully after expiration and always check dates when buying to optimize weed and feed treatments.
