Scotts Weed & Feed vs Triple Action: Which Scotts Bag Do You Need?

Scotts Weed & Feed vs Triple Action

Both of these are Scotts Turf Builder bags, so this is not a brand fight; it is a "which one does my lawn actually need this year" decision. Scotts Turf Builder Weed & Feed is a two-job bag: it feeds the lawn and kills broadleaf weeds (dandelion, clover, chickweed, plantain) that are already growing. Scotts Turf Builder Triple Action is a three-job bag: it does the same feed-plus-broadleaf-control, then adds a pendimethalin pre-emergent that stops crabgrass seeds from sprouting in the first place.

That pre-emergent is the whole decision. If your real problem is crabgrass coming back every summer, you want Triple Action, and you want it down early in spring once the soil holds about 55 deg F for a few days, before crabgrass germinates. If your lawn just has a flush of dandelions and clover and crabgrass has never been an issue, plain Weed & Feed is the cheaper, simpler pick, and you apply it whenever those broadleaf weeds are actively growing.

One thing to clear up first: standard Scotts Weed & Feed is not a pre-emergent and will not prevent crabgrass. If that is what you came here to learn, the rest of this page sorts out exactly when each bag earns its place.

Quick verdict

Triple Action wins when you need to prevent crabgrass and want one early-spring pass that also feeds and kills broadleaf weeds. Weed & Feed wins when crabgrass is not your problem and you just need to clean up broadleaf weeds and feed an established lawn.

Pick Scotts Weed & Feed if...

  • Crabgrass is not your problem; you mainly have broadleaf weeds like dandelions, clover, chickweed, or plantain.
  • Your lawn already has those weeds actively growing and you want to feed the lawn in the same pass.
  • You missed the early-spring soil-temperature window for a pre-emergent, or you are applying in the fall.
  • You want the simpler, cheaper bag and do not need crabgrass prevention.
  • You are not planning to overseed for at least 4 to 6 weeks after applying.

Pick Scotts Triple Action if...

  • Crabgrass comes back every summer and you want to stop it before it germinates this year.
  • You can get it down in early spring, once soil holds about 55 deg F for several days, before crabgrass sprouts.
  • You also have broadleaf weeds and want one bag to prevent crabgrass, kill broadleaf, and feed all at once.
  • Your lawn is established (not seeded or sodded within the last 4 months) and you are not overseeding for ~4 months.
  • You want to match the formula to your region (standard for the North and transition zone, Triple Action South for warm-season lawns).

Frequently Asked Questions

What is the difference between Scotts Weed & Feed and Triple Action?

The difference is crabgrass prevention. Both bags feed the lawn and kill broadleaf weeds like dandelion and clover with a 2,4-D and mecoprop herbicide blend. Triple Action adds a third ingredient, the pre-emergent pendimethalin, which stops crabgrass and other annual grassy weeds from germinating. Weed & Feed does not contain a pre-emergent, so it cannot prevent crabgrass. If crabgrass is a recurring problem, Triple Action is the bag; if you only need to clean up broadleaf weeds and feed, Weed & Feed does the job for less money.

Does Scotts Weed & Feed prevent crabgrass?

No, standard Scotts Turf Builder Weed & Feed does not prevent crabgrass. It is a post-emergent broadleaf product, meaning it kills weeds that are already growing (dandelions, clover, chickweed) but contains no pre-emergent to stop crabgrass seeds from sprouting. For crabgrass prevention you need a product with a pre-emergent such as Scotts Turf Builder Triple Action (pendimethalin) or Scotts Halts. Apply that in early spring before crabgrass germinates, because once crabgrass is up, a pre-emergent will not touch it.

When should you apply Scotts Triple Action vs Weed & Feed?

Apply Triple Action in early spring, as soon as soil temperatures hold around 55 deg F for several days and before crabgrass germinates; this is the only window where the pre-emergent works. Weed & Feed is timed differently: you apply it when broadleaf weeds are actively growing, which can be spring or fall, with daytime temps roughly 60 to 85 deg F. So Triple Action is a calendar-and-soil-temperature decision, while Weed & Feed is a "the weeds are out now" decision.

Can you use Scotts Triple Action and Weed & Feed in the same year?

Yes, but you rarely need both, and never within a few weeks of each other. A common program is Triple Action in early spring for crabgrass prevention plus the first feeding, then if broadleaf weeds flare up later in the season you can spot-treat or use Weed & Feed once those weeds are actively growing. Keep applications at least 6 to 8 weeks apart so you do not stack nitrogen or overlap herbicides, and remember both contain broadleaf killers, so doubling up close together stresses the lawn without extra benefit.

Which Scotts product is better for crabgrass?

For crabgrass, Triple Action is the better of these two because it contains a pendimethalin pre-emergent that prevents crabgrass for up to about 4 months. Weed & Feed has no crabgrass control at all. Keep in mind that even Triple Action prevents crabgrass rather than killing it; if crabgrass has already emerged, neither bag will remove it and you will need a dedicated post-emergent crabgrass killer instead. The win with Triple Action is getting it down early, before the crabgrass seeds wake up.
