How to get rid of quickgrass and tall fiscue


1. Mow your lawn adjusting your lawn mower to the lowest setting (if we are in the heat of the summer or in drought conditions, must water the entire lawn after this procedure until it grows back to a healthy 3-4 inches in length).

2. Heavily water the areas infected by the Quack grass. The Quack grass will grow faster than the grass you want. When the Quack grass is about 5-6 inches tall, your lawn should only be about 2-3 inches tall.

3. Wearing gloves, soak the sponge with the non-selective herbicide in a safe area away from your lawn. Be sure to squeeze the excess product out so it does not drip.

4. Brush the sponges over the blades of the problem grasses. For larger areas you can attach sponges to the bottom of the wagon so that they are about 5 inches off the ground (use rubber bands or duct tape). Pull the wagon around the infected areas of the yard. The sponges will “paint” the Quack grass with the non-selective herbicide.

5. After a few days you will begin to notice the quack grass dying off. For full results follow the time frame and instructions on the non-selective herbicide label.

6. After the quack grass dies you can dig it up or allow it to decompose naturally. You will need to reseed these areas to avoid any further infestation of weeds or problem grasses. Please call us if you need instructions for corrective seeding of your lawn.

7. For quackgrass control continue to fertilize and water your lawn regularly. This will help prevent further infestations.
