X-posting on gardening thread...
I have what I guess you could call an ornamental garden in the backyard. It has knockout rose, mountain laurel, purple lantana, lily of the nile, plumbago, mexican bush sage, Esperanza, texas sage, red bud, weeping red bud, red yucca, pink skull cap, purple heart, indian hawthorne, artichoke agave, turks cap, loropetalum, soft leaf yucca, variegated ginger, abulia, liziope, oak leaf hydrangea, beauty berry, and black & blue salvia, and flax lily. 80% of these were installed in Nov 2019, and the remaining 20% is going to go in over the next 60 days.
Unfortunately I also have the dreaded NUTSEDGE coming up in the mulch. Nutsedge laughs at Roundup and Glyphosphate. Manual pulling makes it worse.
In the past I've used an Image/44% Glophosphate mix to kill it but I literally had to paint it onto the shoots. That's no longer feasible here.
I have some SedgeHammer (halosalfuron) and a container of Dismiss (sulfentrazone) and I'd like to do a spot spray in the areas that have trouble, but I'm finding conflicting info on if that is OK in my landscape garden. The Sulfentrazone label says not to use it in ornamental areas, but there are lots of threads online where it's fine. SedgeHammer says its OK but apparently doesn't work as well as the Dismiss. Apparently the Dismiss persists in soil for a year, whereas the SedgeHammer is much shorter. I'm wondering if when they install the new stuff in the next month or two if that's going to interfere with the transplant process if I spray now.
Anyone have any thoughts/ideas?
