When Is The Best Time To Control Weeds?

One of the most frequently asked questions we hear is, “When is the best time to control weeds in the lawn?” The answer is, “It depends.”

First, we must determine several things:

  • Is it a broadleaf weed or grassy weed?
  • Is the weed an annual, biennal, or perennial?

Knowing these items will help identify the weed so our next question is:

  • Why is it here?

Weeds Are Very Opportunistic

Generally speaking, weeds grow in areas of turf that are under stress, mowed too short, or thin bare areas. Where lawn grasses are not competitive, weeds creep in.

Several practices can be put into play to reduce weed pressure and help restore the lawn to its original beauty.


Proper Mowing & Watering

Improper mowing and watering are the primary reasons lawns have weeds. Both cultural practices, if done incorrectly, contribute to heavy weed pressure. A lawn improperly cut weakens the turfgrass roots and may take as long as eight weeks to recover.

For cool season grasses, it is best to cut at 3 ½ inches. Warm season grasses are different and may be cut shorter, generally around 2 inches, during their active growing season.

Watering should be done deeply and infrequently; a good rule of thumb is 1 hour of watering every week. Lawns watered too frequently or not enough may develop diseases which weakens the lawn causing an increased presence of weeds.

Timely Fertilization

Begin with a sound fertilization program by either hiring a lawn care professional, such as NaturaLawn of America, or doing it yourself.

Select the proper fertilizer based on a soil test and the time of the year as every lawn has different needs. Spreaders must be calibrated correctly, otherwise fertilizer may be spread unevenly. Too much fertilizer can harm grass, and too little can be ineffective.

Aeration & Seeding

Reducing weeds can also be obtained through aeration and seeding. Core aeration opens up the soil, pulling up millions of microbes and depositing these little guys on top of the turf. As the soil cores break down, these microbes feed on existing thatch. Removing thatch reduces stress on the lawn because it allows nutrients and water to flow more freely to the roots.

Aeration also reduces compaction, making it easier for turfgrass to breathe and allowing new seed to grow in its place. A think stand of grass helps “choke out” weeds.

When Should I Control Weeds? 

To survive, weeds require favorable conditions. Unfortunately, weeds are everywhere and can survive in nearly any environment. This means in order to control weeds best, a healthy environment is needed so that turfgrass can crowd them out naturally. 

Continual upkeep is important for weed control. If you need assistance with helping your turfgrass thrive, please get in touch with your local NaturaLawn of America office today.

My lawn is beautiful.  It has never looked this good.  It looks like lush green velvet.  We only had one dandelion this spring and it was on the edge of our property, so it must have been the neighbor’s!

Jennifer L. Lloyd – Bear, DE

For over 22 years, NaturaLawn of America has been creating naturally beautiful lawns that are safer for you, your family, pets and the environment.  Of course our satisfied customers say its best!
In less than a year, my lawn has gone from one of the worst on the block to among the best.  This is quite an accomplishment considering we have well water and, therefore, never water the lawn.  The  service is also top notch – friendly, knowledgeable and always willing to explain why they’re doing what they’re doing.

Stewart Kaufman – Southbury, CT

NaturaLawn of America has cared for my lawns now for 10 years (2 houses) and I am completely satisfied with your company.  My service technician is friendly, caring and knowledgeable.  I’m happy with the results, how you care for my lawn and the prices you charge – happy enough that I recommend you to others and I tear up ads from competitors without even reading them.
My husband and I are currently acquiring a house in New Hampshire.  There is no question that I will want NaturaLawn of America service at that house.  It is a true pleasure to work with a “national” company that treats their customers in a local business manner.

I’m just dropping you a note to let you know that we are very pleased with your lawn service, the way we are treated and the beautification of our lawn.  Many families have seen our lawn and are very impressed by the way it looks.  They are even more impressed that you are an organic-based company and use 85% less chemicals and pesticides.  We have referred many of our friends and neighbors and will continue to refer people as the opportunity arises.

Jack & Sherrie Decker – Plainview, MN

Our lawn is beautiful.  Thank you for the great results AND for protecting my family and the environment from unnecessary chemicals and pesticides.  It’s nice to have a lawn care company that is concerned about my lawn, my family and the environment.  When people are looking for a healthy, nice lawn, friendly service AND a safer lawn care option, I highly recommend they call NaturaLawn of America.

You are doing a great job! We are glad we switched to NaturaLawn of America and are spreading the word about the super job you do.

Steve Pfannenstein – Rockville, MN

I wanted to write and let you know how pleased I am with NaturaLawn of America.  I had never used a lawn service before.  I’m against putting more chemicals into the environment, so I decided to see what you could do organically.  My lawn was 1 ½ years old – builder grade seed on builder soil! It was a lawn in need of some help, but I didn’t know how wonderful it could look.
Two days ago, my neighbor (who used one of the top chemical lawn companies) sounded a little baffled and asked what I do to my lawn – It looks like a carpet!  We just smiled and said “NaturaLawn of America”.  That’s when I took a good look at my lawn and everyone else’s - our lawn is thick and green.  Despite the recent drought, despite our lack of attention to our lawn, and despite its humble beginnings, it is a magnificent piece of work.

Paul & Doris Pavlichek – Mount Airy, MD

This is our second year with NaturaLawn of America and I can’t say how much we appreciate your work. The yard is awesome!
