The next two weeks provide you with the prime opportunity to gain control over the Japanese stilt grass (Microstegium vimineum) population on your property. This annual grass is either about to flower or has just started to flower depending on its exposure to light. If you mow or weedwack the grass when it is flowering you will prevent it from setting seed; as an annual grass, this effectively helps to control the population. Please note, if you have had the stilt grass population for a few years on your property, it will take more than one season to gain control. The seeds of stilt grass can stay in the seed bank for up to seven years. Good luck and happy controlling.
