Description

Scotts® WeedEx™ Prevent with Halts® prevents crabgrass and other problem weeds for a beautiful lawn all season long. In early spring, apply when the lawn is dry to prevent the germination of crabgrass, foxtail, spurge, barnyardgrass, fall panicum, and oxalis. Apply in the fall (August-October) to prevent moss (except in California), or to prevent the germination of Poa annua, henbit, corn speedwell, and chickweed. We recommend using a Scotts® spreader to apply this product. For Scotts® broadcast/rotary spreaders, use a setting of 2 ¼. For Scotts® drop spreaders, use a setting of 4 ½. For Scotts® Wizz®, use a setting of 3 ¼. For best results, the lawn should receive ¼ to ½ inch of water from rainfall or watering within 2-3 days after application. Rain, snow, or freezing weather after application will not affect performance. This product controls crabgrass in its early stages of growth. It does not control mature crabgrass and other existing weeds. Do not apply to Dichondra and Bentgrass. One 10.06 lb. bag of Scotts® WeedEx™ Prevent with Halts® covers 5,000 sq. ft.

How to Use

  • Check bag for spreader setting
  • When using a Scotts® broadcast or Wizz® spreader, make a perimeter pass of your lawn with EdgeGuard® on to protect non-lawn areas. Then, make parallel internal passes 5 ft. apart to ensure even coverage.
  • When using a Scotts drop spreader, start 5 feet from the edge of your lawn and walk the outline of your lawn. Then, make internal passes across your lawn, overlapping the wheel marks to ensure uniform coverage.

Where Not to Use

  • Do NOT apply to dichondra or bentgrass lawns

Where to Use

  • Can be used on all lawn and grass types EXCEPT dichondra and bentgrass

When to Apply

  • Apply once in spring and once in the fall
  • In southern California, apply before March 1st
  • In northern California, apply before mid-March

How Often to Apply

  • Apply a maximum of twice a year with a minimum of 2 months between applications

Watering Tips

  • It is not necessary to water in immediately. For best results, lightly water the lawn to rinse particles from grass blades (up to ¼ to ½ inch) within 2-3 days after application.

Using with Other Products

  • Follow with Scotts® Turf Builder® Weed & Feed or with Scotts® Weed Control for Lawns

Rated 5 out of 5 by from Great looking grass This stuff works great in our backyard that only gets parts sun. We applied it in early May and our grass looks great enough though we have had lots of rain for our area. This stuff is easy apply and the earlier in the spring the better.

Rated 5 out of 5 by from Better late than never. The shipment of the product came late for my first application so I have just now applied it. I live in southern Michigan and an unusually cool and wet spring brought out the weeds prior to when my complimentary product arrived. I can say that later is also good. The product is very easy to put down. It flows evenly and covers the yard nearly perfect. I have been a Scott’s user for many years and new improved formulations are always appreciated. Thank you.

Rated 5 out of 5 by from No More Weeds Scotts WeedEx Prevent with Halts is one of the better lawn products I have ever used. My grass is now weed free thanks to this wonderful product I have used other products in the past but none have worked as well as this one. Truly, an effective weed preventer for my lawn.

Rated 5 out of 5 by from No crabgrass at all after Weedex Weedex by Scotts has done a great job in keeping crabgrass from sprouting and at this point in the year, I have seen no crabgrass at all in my bermuda lawn. I had previously used Scotts week and feed, but between the Weedex and that product, I now see no weeds of any kind. Before using the two products, there were dandelions and numerous other weeds that I can't identify. So Weedex has resulted in a very nice lawn.

Rated 5 out of 5 by from A big help. This product works well, I keep it within parameters and it works on the weeds as it should. I only have a few areas that I use it on because the Weed and Feed took care of most of the weeds but where I used it it worked well.
