Will Lawn Grass Reseed Itself

Will Lawn Grass Reseed Itself?

Answer: Yes, it will.

Different types of grass can spread under the right conditions and make a lawn thicker, healthier, and easy on the eyes. It is important to understand the nature of your lawn grass and the way it propagates itself. Because by understanding the nature of your lawn/ grass, you can maintain it better and help it to grow further and become even better than it is right now. 

Lawns that are mowed regularly do not reseed themselves. In other words, they cannot become thicker and spread wider through seeds. Why? Because they do not get a chance to grow to the right size to produce flowers and produce grass seeds. However, most orchids do not really need seeds to propagate themselves. This is because they can grow vegetatively via side shoots either underground or above the topsoil. 

So the answer to the question, “Will lawn grass reseed itself?” is “Yes, it will.” It will reseed itself if it is allowed to grow long enough to produce flowers. When a lawn grass reseeds itself, it grows and becomes thicker and more vibrant. However, if it is mowed it will not produce flowers and reseed itself. Nevertheless, it can still grow bigger and more vibrant through growing underground vegetatively via side shoots. 

How Most Lawn Grass Species Propagate Themselves 

Re-seeding 

Most lawn grass species propagate themselves by re-seeding. How does re-seeding happen? Well, it happens when lawn grass are allowed to grow tall and mature enough to produce flowers (inflorescence). 

Lawn grass usually only develop flowers when they are allowed to grow long enough and to grow enough blades. Once lawn grass grow enough blades, they usually develop their stems and it is from their stems that clusters of small flowers develop. Conditions such as moisture, sunlight exposure, and temperature have to be right for lawn grass to grow, produce more blades, and develop flowers. 

Typically, lawn grass flowers have both female and male organs on the same flower. However, some species produce male and female parts in separate flowers. 

When lawn grass pollens fertilize lawn grass ovaries, seeds are formed. The seeds cannot be formed without the fertilization of the ovaries with pollens. Lawn grass pollens are usually transferred by the wind. But they can also be transferred by insects. 

Once lawn grass seeds form and mature, they are frequently scattered by the wind. This is the re-seeding. The young seeds then grow into small grass plants, which develop and then also become parent grass plants for other grass plants. It is the continuous re-seeding that gradually makes lawns thicker, less patchy, and more vibrant. 

Rhizomes

Lawn grass also propagate themselves vegetatively via rhizomes or side shoots. The side shoots typically spread underneath the soil. 

So what are rhizomes? Rhizomes are stems that grow laterally from the base of a plant. They grow laterally from the base of grass plants. And when they become mature enough, new shoots (tillers) grow from them upward. With time, these shoots mature and become “independent” grass plants. 

Tillers are complete grass plants. They too can produce clusters of flowers and seeds when they are left to grow and mature. Their seeds can also be dispersed by the wind to form new plants. 

Lawn grass plants typically propagate themselves via rhizomes when the ground they are in is sufficiently moist. When the ground is dry, propagation via rhizomes/ side shoots becomes difficult and rare. 

Stolons

Some lawn grass species propagate themselves via structures known as stolons. Stolons are lateral stems and they grow above ground from the stem base of lawn grass plants. 

Once stolons have grown to maturity, they produce their own blades of leaves and help lawns to become thicker. 

Grass species that develop stolons are perfect for thatching.

Why Letting Your Lawn Grass to Re-seed is Not a Good Idea

Many people delay cutting their lawns to allow them to grow tall enough so as to re-seed and grow new grass to make their lawns thicker. Well, this might seem like a good idea but it is not. It is not a good idea because of several reasons. 

Neighbors will not like it 

Your neighbors will not like a home in their street looking like a countryside home with good pasture for livestock. So if you want your neighbors to at least be friendly with you, you’ve got mow your lawn regularly. 

Fire risk

Overgrown lawns are a fire risk especially during summer when the heat can set them ablaze. Because overgrown lawns are a fire risk, many cities, and councils around the world find homeowners who do not regularly mow their lawns. 

Regular mowing will help you control weeds

When you delay mowing or do not mow regularly, any weeds growing amongst your grass plants will get ample time and opportunity to grow and thrive. This can negatively affect your lawn instead of building it and making it thicker. Therefore, you should not avoid mowing, since doing so will give weeds a chance to attack and thrive on your lawn. 

Most lawn seeds are hybrid 

What most people do not know is that most lawn seeds currently available on the market are hybrid. Some of them will not produce flowers or viable seeds even if they are given ten or twenty years. Therefore, allowing them to grow taller to re-seed is really a waste of time. 

Not mowing wastes nutrients 

Failure to mow lawn grass or giving lawn grass time to overgrow wastes nutrients. Because the nutrients are used for vertical growth, leaving fewer nutrients for lateral growth and the thickening of lawns. 

How to Make Your Lawn Thicker and More Vibrant Without Re-seeding 

Follow the steps below to make your lawn thicker without resorting to re-seeding. 

  1. Improve your lawn soil. Get the soil tested and add lime or sulfur depending on its pH to balance it.
  2. Fertilize. Use an organic fertilizer on your lawn as frequently as it is recommended by the manufacturer. Fertilizing will give your grass the nutrients they need to thrive.
  3. Set up a sprinkler system. Lawns need good moist soils to thrive and look evergreen. Therefore, give them that by setting up a good sprinkler system to evenly spray them with water. Properly watered lawn grass can also propagate themselves and form a thicker lawn through rhizomes and stolons.
  4. Do proper maintenance regularly. Doing proper maintenance regularly will make your lawn healthy and increase its chances of thriving. Lack of proper care will only make your lawn thinner and less vibrant.
