What Is Lawn Reseeding, Why You Should Reseed and When To Do It.

Reseeding or overseeding is a very important lawn care task, yet few homeowners ever do it or know that they should. The common misconception is that if you fertilize your lawn each year that’s all you need to do and why would you waste money on new grass seeds when the lawn looks good and is green? Truth be told, the grass plant has a best by date and after 4 years or so the plant gets slower and weaker and starts to thin. That is why you want to make sure that every 2 or 3 years you are adding some new players into your lawn’s team. When the grass gets thin in areas the lawn becomes ripe for weeds to take over, which is not a situation we want to get into.

How to know if your lawn needs reseeding.

  • When you look at your lawn, does it look thin in areas?
  • Can you see the earth between the grass blades?

If you answered yes to either of these, then overseeding is necessary for your lawn.

What is lawn reseeding?

Reseeding or overseeding is the practice of seeding new grass plants into an established lawn. Overseeding is in most cases done to grow a thicker looking lawn and to fill in bare spots. The end goal is to have a better looking, rich green and happy lawn. 

Benefits of overseeding.

There are two major benefits to overseeding every two or three years. 

  1. Thick and lush looking lawn. A healthy lawn has few, if any, weeds. If it is kept at a mowing height of two inches or taller, your lawn stays much healthier.

  2. Disease resistance. The latest varieties of grass seed that you sow this year will have better disease resistance than the varieties already in your lawn. 

When you should reseed your turfgrass.

Reseeding or overseeding can either be done in the spring or the fall. Both times of year are great for repairing thin or dead patches. A good to remember is that you want to make sure that the air temperature is at least 18c for a minimum of at 5 or 6 days if you are overseeding in the spring. If reseeding in the fall, make sure that the seed is applied no later than October 15th as it needs time to establish roots before winter.

Interesting information. Our local golf course reseeds every year in October, maybe that's why their grass always looks great!

I agree, and the best defense against weeds is to grow healthy grass that is kept long. It's strange to think that the grass itself can shade out unwanted weeds, the more grass blades, the better! Thank you for your comment.
