Question:<\/h3>\n

A neighbor of mine in ‘mistake’ planted a Rosa Rugosa. Last year, they had the mother plant removed, but through either rhizomes or seed, MANY new plants developed this year. They again have a company coming in to remove any visible plants\/rhizomes. I think they will need to be diligent in spraying an herbicide to kill anything coming up.\u00a0 My question to you PLEASE: What is the best herbicide for them to use in the future?<\/strong><\/p>\n

As a university we cannot recommend one product over another.<\/p>\n

I can share this\u00a0fact sheet that gives recommendations\u00a0<\/a>of the active ingredient needed in an herbicide to be effective in that process.\u00a0 Click on the blue underlined text and go to the bottom of the article at you are looking for what NOT to do.<\/p>\n

“Roses are sensitive to postemergence broadleaf herbicides that may be used in landscapes, such as 2,4-D, triclopyr, and dicamba; these should not be used in or near planting beds with roses. Generally, use broadleaf herbicides with great care when rose plants are present in nearby landscapes so as not to cause damage from drift.<\/i><\/p>\n

Roses are also very sensitive to glyphosate (Roundup and many other trade names), which can be absorbed through the green stems in addition to the leaves.\u00a0Glyphosate damage<\/a>\u00a0may appear at\u00a0bud break<\/span>\u00a0the following spring after a summer or fall application that contacts leaves or stems; symptoms include a proliferation of\u00a0small, narrow shoots and leaves<\/a>.“<\/span><\/i><\/p>\n

In most cases, diligence in cutting or mowing the tiny sprouts is the way to go if it was not an established planting.\u00a0 This weakens the root system to the point where it can’t continue to sprout.\u00a0If the plant is near a water source then this is the ONLY method that can be used. No herbicides can be used at the water’s edge.\u00a0\u00a0<\/b>\u00a0See for more information: https:\/\/www.maine.gov\/dacf\/mnap\/features\/invasive_plants\/rosa_rugosa.htm<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"
