 AI Overview        When weeds "talk," they are telling you about the health and conditions of your soil. Horsenettle (Solanum carolinense) thrives in soil with very low calcium and very high magnesium.What Horsenettle is Telling YouIn regenerative agriculture and soil health, weeds are often used as biological indicators. Horsenettle is sending a clear message about your soil:Soil imbalance: It indicates your soil calcium levels are too low, and magnesium levels are too high. This causes the soil to become tight and crusty.Tough survivor: Horsenettle is a stubborn, deep-rooted perennial. It has sharp thorns and produces green, tomato-like berries.

How to Respond to the WeedsTo address the weed and the underlying soil problems, consider the following actions:Fix the Soil: Add agricultural gypsum to the soil to improve the calcium-to-magnesium ratio, which will help loosen up tight soil and make the environment less friendly to horsenettle.Control the Plant: Because it has deep taproots and creeping rhizomes, horsenettle is very difficult to pull by hand. For pastures, a systemic herbicide applied in late summer or fall when the plant is in bloom works best.Safety Warning: All parts of horsenettle (except the mature, ripe berries) are highly toxic to humans, pets, and livestock. Wear thick gloves when handling
