## 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.
