Black medic is a common weed found in most lawns and gardens, but is often mistaken for clover. Black medic is a low-growing weed that grows between 4 inches to 2 feet long. The leaves can have a similar look to that of clover, but are not as rounded as a clover leaf. They are most commonly 5/8 inches long and 1/2 inch wide. A bright yellow flower cluster appears at the tip of the stalk, with the cluster consisting of approximately 50 flowers.
Black medic seeds germinate at temperatures between 50 to 75 degrees, both in spring and fall. Flowering can occur approximately 6 weeks after the seedlings emerge in the spring, and will continue throughout the growing season.
The best way to eliminate black medic from your lawn or garden is prevention. Start the spring off with a pre-emergent application, stopping the seeds from growing in your lawn before it becomes a problem. If, however, you forget to apply the pre-emergent to your lawn in the spring, regular blanket fertilizer applications will eliminate this weed.
