In the fall I ripped up my entire backyard and restarted with new soil/grass seed as the yard was literally 100% weeds. Managed to successfully grow grass and it looks great, but I know this weed seeds are probably still under that soil so I’m gonna be following/asking questions in the near future about good pre-emergents , weed killer etc. My yard doesn’t have to look like a golf course but I definitely want to keep it looking good. The following were weeds I identified prior to the re-do:
Crabgrass, spurge, clover, ground ivy, nutsedge, sweet violet. The clover was particularly bad in the spring and spurge in the last summer. Should be fun lol.
