The Quick Serge of Spring Weeds

Spring weeds surge quickly in Tucson because warmer temperatures, longer daylight, and winter moisture line up almost perfectly for rapid germination and weed growth in in the spring. Even a light amount of rain in late winter can activate thousands of dormant seeds. These seeds are waiting just beneath the soil. Once the soil warms, many local weeds, like spurge, goatheads, and London rocket, can sprout in just a few days and establish themselves before homeowners even notice the first green shoots.

When March approaches, growth accelerates. Annual weeds complete their life cycle fast, pushing out leaves and spreading across open soil while conditions are mild. Perennial weeds take advantage of the same window, using the early season to strengthen their root systems and expand into new areas. Without early intervention, these plants can double or triple in size within a couple of weeks, especially in yards that received winter irrigation or have shaded, moisture‑holding soil.

By mid-spring, the combination of warm days and cool nights create ideal conditions for explosive spread. Weeds begin producing seeds quickly, setting the stage for even heavier growth the following year. Getting ahead of them early—before germination or right as seedlings appear—makes a dramatic difference in how manageable the season becomes.
