Basic tips for weed control

  • Minimize soil disturbance. Digging and cultivating brings weed seeds to the surface. When exposed to light the seeds will germinate. 
  • Cover bare soil with groundcovers or mulch. Bare soil is an invitation for weeds to move in.
  • Do not let weeds flower and go to seed. At a minimum, cut them back or use a string trimmer.
  • Pull weeds when the soil is moist. This will make the job easier!
