Snapshot can be reapplied in 60 days. You should water it in as soon as possible following the application.
Snapshot is a post-emergent herbicide only, so it is not made to kill any existing plants. Geranium cinereum (ballerina) is listed as intolerant of over-the-top Snapshot applications, while the common weed Carolina geranium is prevented from germinating by using Snapshot. Geranium incarnum and Geranium subcaulescens are listed as tolerant plants of Snapshot. Since the exact species you mention is not listed as either tolerant or intolerant, we would recommend testing over a small area before treating around a large area of this groundcover, or selecting a different product for your needs.
If you would like to tell us more specifically which plants you are wanting to kill/prevent and which are the desirable plants, then we can better assist you.

We understand that it is tricky to know what setting to use on your spreader, but since there are so many available on the market, it is important to calibrate your Speedy Green equipment based on your application and the product you are using. For Snapshot 2.5 TG, you will use 2.3 to 4.6 pounds of granules per 1,000 square feet. Please refer to the product label for the best rates for the area you are treating and the weeds you are targeting. Please see below for more details on how to calibrate your spreaders. Many folks will start at either the lowest setting or at 1 settinglower than the middle setting. We also have an excellent instructional video here.
Almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet. So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting. You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing 4 ounces of any type of product of similar granule size, or of the Snapshot in the spreader. Start with a low setting and start walking your marked off area at a normal pace. You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet.
Since Snapshot is a pre-emergent herbicide and needs to be watered in, you want to be sure the area is not so dry or sloped that the product will not just run out of the area when you water it. You may want to use sprinklers, a hose, or a watering can to moisten the treatment area first to help the granules stay in place before activating with water.
Snapshot 2.5 TG is best applied directly to the soil and then watered in as it is a pre-emergent herbicide. If some granules get on the leaves during application, these should be knocked off if they do not come off after watering.
Snapshot 2.5 TG is not labeled to be used in any turf grasses. It is meant to be used in landscape beds and around trees. Please provide the targeted weeds for an alternate recommendation. Thank you!
Since timing can vary widely by region, we recommend contacting your local county extension office for the best application timing in your specific area. They will know exactly when you should apply a pre-emergent for best results.
