The answer to 'sod installation has weeds' is that weeds in newly installed sod are a common problem. Weeds can come from the sod itself, the soil used for installation, or nearby sources. Symptoms include patchy growth, discolored or dying grass, and the presence of weed species. To solve this, you'll need to identify the weed types, address any underlying soil issues, and implement a weed control plan.
For minor weed problems, homeowners can often handle this with DIY methods like hand-pulling weeds, applying selective herbicides, or overseeding with new sod. However, for severe or persistent weed infestations, it's best to call in a professional landscaper. They have the expertise and tools to properly diagnose the issue, treat the weeds, and get your new lawn established successfully.
