Weed Services FAQs, answered by experts

They regularly monitor health, applying preventative fungicides and providing customized care to reduce disease risks.

Weed control applications usually cost around $100 each for a standard-size yard, and most professionals charge between $30 and $60 per hour for manual weed removal. Your total is affected most by the size of the weeded area. Some weed service companies offer weed control treatments, selective herbicide spraying, and manual removal and upkeep as part of a package, costing around $600 annually. You might pay less if you hire the same company for other lawn services, like flower bed upkeep, aeration, overseeding, and pesticide application.

They compete for nutrients and water, potentially stunting desired plants.

Johnsongrass and crabgrass are invasive weeds that can overtake your lawn. Crabgrass is a low-growing grass most often seen in lawns, flower beds, and vegetable gardens. While you may find Johnsongrass growing in your lawn, it will also grow in pastures, crop fields, and the edge of the road. Johnsongrass is much coarser than crabgrass. If left alone, Johnsongrass can grow up to 8 feet tall. 

There are tools known as “sprinkler donuts” that are specially designed to aid in cutting the grass around your sprinkler heads by protecting them from your mower or weed whacker. You can also use a pair of hand shears to do the job manually if you’re willing to get a little dirty.
