Dimension 2EW Herbicide will stay in the soil up to two years. It will be unsafe for the animals to graze until after the Dimension has left the soil.
Dimension 2EW Herbicide is not labeled for creeping Charlie. Unfortunately, we are not aware of a pre-emergent labeled for that particular weed.
Dimension 2EW is labeled to control poa annua (annual bluegrass) before it emerges and should do a good job when applied at the right time. Please refer to the product label for complete instructions. If you are already dealing with Poa Annua, you will need to use a post-emergent, and we do carry several. Which you choose depends on your grass type. Certainty is a good choice, but please refer to the label to ensure it can be used on your lawn type.
Dimension 2 EW and Pendimethalin are labeled to prevent many of the same weeds, so we would recommend choosing the product that best fits your needs rather than making unnecessary applications. If you have specific questions about which pre-emergent would be best for your situation, you may reach our Customer Service team at 866-581-7378 M-F 9a-5p.
Dimension 2EW Herbicide can stay in the soil for up to 6-8 months depending on the application rate. Once the area is dry you will not track it into the house since you need to water in ½ inch after application so that it gets into the soil to create a barrier.
Yes, Dimension 2EW Herbicide is labeled safe to use on Bahiagrass.
Dimension 2EW Herbicide should not be applied around edible trees/orchards. We recommend consulting with your local Master Gardener for a product that can be applied safely for pre-emergent control.
We would not recommend applying herbicides such as Dimension 2EW Herbicide during active precipitation. Instead, you could use a higher volume of water, or you could irrigate the application yourself with at least 1/2 inch of water.
Both Dimension and Gallery are great pre-emergents and are OK for use around non-bearing vineyards only. We do not currently carry any pre-emergents that can be used around bearing vineyards.
Dimension 2EW is one of our most popular pre-emergents for crabgrass as well as many other broadleaf weeds, and it can safely be used on St. Augustine grass. Please check the product label to ensure that it will control the other weeds that you are targeting.
The program that is chosen will depend on how long Dimension 2EW Herbcide lasts in the soil. For example, if Program 1 is done, it will provide 3-5 months of pre-emergent control. Most pre-emergent products will have to be applied at least twice a year to prevent Spring and Summer weeds.
The length of time Dimension 2EW Herbicide lasts depends on the rate used, it can last 3-6 months.
For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year. If you apply pre-emergent every year, you should not have issues with crabgrass long term. Dimension 2EW is one of our most popular pre-emergents for crabgrass.
Dimension 2 EW is safe to apply to St Augustine grass. We would not recommend applying to turf that is stressed by heat, frost, or drought. We would also recommend split applications. Please see the rate table on page 5 of the product label for recommended rates for your area.
