We had 6 inches of rain. I have about 18 inches of water standing in my duck hole. I have jap millett that is headed out and about 24 to 30 inches tall. I am pretty sure it will survive. What I am hoping is that the areas I didn't get sprayed that are grown up in 18 inch cockle burrs will die in the standi ng water before going to seed. Does anyone have any experience with flooding cockle burrs that are still actively growing? Will they die?
