The answer to 'why is my sod weeds' is that weeds can easily invade and grow in new sod due to a few common reasons. Improper soil preparation, lack of proper maintenance, and the introduction of weed seeds from the sod supplier can all contribute to weeds sprouting in your new lawn.
Weeds thrive in the nutrient-rich soil used to lay sod, and if the area wasn't properly prepared and treated before installation, weeds can quickly take over. Additionally, sod may come with some weed seeds already present, which can then germinate and spread. Proper mowing, watering, and applying the right herbicides and fertilizers are key to preventing and controlling weeds in new sod.
