## Description

Dimension 2EW Herbicide - 0.5 Half Gallon (64 Ounces)

Review: Prevents Weeds When Properly Applied - I've used this product for multiple years to apply the barrier to keep various lawn weed seeds from popping. In Phoenix, I apply in January after the dip for our cold temperatures passes before the soil warms enough to trigger dormant weed seed sprout -- of the seeds that have been blowing and landing in the dormant Bermuda grass. Your timing will differ. Fortunately, I don't have crabgrass in my yard, but I did use it to try and control the crabgrass in son's yard. For that, you add surfactant for any post emerging crabgrass. I will sometimes make a second pass a few months later for the spotted spurge seeds that seem to carry everywhere. I mix this up in my 4 gallon backpack sprayer, add the blue dye and spray the whole lawn, except any patches where I need to add seed -- allowing an unsprayed buffer zone. Buying in economy size is my approach. Seems to have decent shelf life.
Review: Works really well - I applied as directed in August, before a big rain. It does appear to have greatly reduced the number of weeds. The only problem is getting a big rain to happen so I can apply it again! It was also helpful to add some temporary dye (sold for this purpose) to the mixture, to tell where I had already applied it. Update, 2 years later: This stuff has made my life SO much easier! I used to spend a large part of my time regularly pulling weeds, to stay ahead of them going to seed. Now I just spray a mixture of this around every 4 months when a major rain is expected (I found that some dish soap seems to work well as surfactant). Getting near the end of the bottle, but still have some from my original purchase left - so while this is pricey, it lasts a long time (as it is concentrated) and IMHO, is priceless ;-)

## Questions & Answers

**Q: can it be used on post emerged crabgrass in Summer?**
A: It won't kill the crabgrass that is already growing.  However, it will prevent the crabgrass seeds released in the summer from mature crabgrass from germinating.  Spray in March to control crabgrass through May, then spray again in June to carry over to September. You can then safely overseed (fescue) in Sept or Oct.

**Q: I have 2acres yard, how much is required?**
A: It will depend on the area you live in.  As a general rule, you will apply .55 fluid oz/1,000 square feet for every gallon of water to be used and use no less than 2 gallons of water.  Here is the phone number for the company help line, 866-581-7378.  Used it for the first time this past jan and it works.  good luck

**Q: Does it treat Sand Spurs?**
A: It's labeled for sandbur if that's what you mean.

**Q: If I put down this pre-emergent, how long should I wait to re-seed?  Can anyone check their Dimensions bag and let me know?  Thanks!!!**
A: From the Dimension label: "Reseeding, overseeding, or sprigging of treated areas within 3 months after a single application or within 4 months of a split application (spring/fall) totaling more than 0.73 oz./1000 square ft. (2 pts./acre) may inhibit the establishment of desirable turfgrasses.  However, overseeding with perennial ryegrass 8 weeks after an application, if slight injury to perennial ryegrass can be tolerated is a recommended exception."In practice, besides the rate, it depends on how heavy the soil is and how much rainfall you get.  It is more mobile in more porous soils and with more rainfall.  It also moves horizontally with runoff from heavy rainfall, concentrating in areas where water pools, but this doesn't prevent Bermuda and especially zoysia from spreading into those areas.

### ⭐⭐⭐⭐⭐ Very Effective Pre-emergent
*by M***. on June 4, 2018*

This prevented almost all weeds in my lawn this past Spring. I live in a new development backing to a wide open field of weeds. My immediate neighbors and I all installed new lawns last Spring. We has an unusually cold period in northern Ohio extending through April. Even so, I applied this 2EW in the first week of April to get a jump on weeds since crabgrass was already coming up and getting established. Although I did have some crabgrass, my lawn was otherwise weed-free compared to my neighbors on both sides. My left side neighbor has a fairly lush new lawn as his yard service concentrated on new over-seeding early May rather than weed control. But he has a huge clover and yellow woodsorrel problem I don't have. First week of June already and I want to reapply to control the summer weed attack of barnyard grass that is coming that was prolific last season. I will aerate and over-seed late fall to hopefully have great results next spring. It's a process.
