Most of the Beacon Silver leaf is marked with a broad silver blotch. The pinkish-purple flowers are larger and more showy than its weedy cousin and appear in early spring. Henbit seldom survives our summer heat, so it s mostly seen from February through June. By that time, if left to its own devices, it will brood a large amount of seed for germination the following fall. Henbit seeds germinate in September as soon as the fall rains begin and the nights begin to cool off.
Prevention is the easiest approach to controlling henbit.
If this control opportunity is missed, they can be controlled by post-emergence compounds such as Trimec. The weed is easier to control in early spring while the plants are small. Also, given henbit s ability to produce large amounts of seeds as even a relatively small plant, control should be initiated early. For garden beds and borders, henbit is easy to prevent by mulching. A 3-inch thick layer of clean organic mulch will effectively prevent germination.
