Prior to planting Ruschia Nana, it is recommended that all weeds be removed by hand or killed with a non-selective herbicide such as Roundup QuickPro no sooner than 2 weeks before planting Ruschia Nana. If applying a pre emergent such as Prodiamine 65 WDG (Generic Barricade) to prevent weeds from germinating, this should be done months prior to planting as pre emergent residuals generally stay in the soil 3-4 months.
If Ruschia Nana has already begun to establish, weed control may be done by hand removal or with a hoe or cultivator. Herbicides are generally not recommended as this could also injure the groundcover however Roundup QuickPro can be used and then replug the bare spots after 2 weeks. Removal of weeds when they are small is key and not allowing the weeds to flower which is followed by seeds and will create more weeds weeks later on.
Contact your County Cooperative Extension Office for specific recommendations for your region on any selective herbicides and timing of application information.
For Bermudagrass, Prodiamine 65 WDG is applied 1.0 to 2.30 lbs per acre in no less than 20 gallons of water per acre (0.36 to 0.83 oz with 0.5 gallons of water per 1000 sq ft). If treating 80,000 sq feet (1.8 acres), you will use 1.8 lbs (28.8 oz) to 4.15 lbs (66.4 oz) in a minimum of 40 gallons of water (2 fills of the 25 gallon sprayer). Prodiamine 65 WDG can be applied in a single application or sequential applications for year round weed control as long as you do not exceed 2.3lbs per acre per year. For best results, the prodcut label recommends that the application be watered in with 0.5 inches of rainfall or irrigation within 14 days of the intiial application to help reach the weeds in the soil and pevent germination.
Timing is key when it comes to pre emergent applications. In early spring, pre emergents need to be applied when soil temps are just below 55 degrees as once soil temperatures reach 55 degrees, this is prime conditions for crabgrass to germinate. Refer to the Crabgrass Seed Germination Map on page 8 of the Prodiamine 65 WDG product label for general timing in your region or we recommend contacting the Master Gardener with your County Exension Office for exact timing recommendations in your area.
