Weed spreading to the side of a road

Crabgrass is a course, clumpy weed. Its presence gives lawns an unattractive appearance. However, that's not the only disadvantage that crabgrass presents.

Once crabgrass begins to grow on your lawn, it will completely take it over, hindering your yard from receiving essential nutrients.

So, it's great that Tenacity removes crabgrass, as lawns can grow healthy grass when crabgrass is gone.

Ground Ivy

Ground ivy isn't as unsightly as crabgrass; it has green, heart-shaped leaves and purple flowers bloom from March to July.

However, even though ground ivy isn't as unattractive as crabgrass, it still has many harmful disadvantages.

Like crabgrass, ground ivy can quickly infest a lawn, driving out native plants. It is also lethal to some animals, including horses, and mildly toxic to other animals.

Like crabgrass and ground ivy, nutsedge can quickly infest yards, vegetable gardens, and flower beds. A nutsedge infestation gives yards a very messy appearance.

Some people try to pull nutsedge out of their yard to remove it. This method often doesn't work because the pulling activates dormant tubers in the nutsedge, causing the plant to spread.

So, it's necessary to use Tenacity Herbicide if you want to remove this pesky weed from your garden.


Bent grass growing out in the backyard
