When you give up mowing your lawn and your lawn grows to excessively high levels and becomes seed, you're doing more harm than good. Much of the grass seeds that appear on the tips of the leaf can be sterile, so don't expect the bare patches to miraculously fill. Seed heads are not always sterile. I'm sure it depends a little on the type of grass and the location.
But, in general, farmers who grow grass as seed start with the same seed as homeowners. However, grass seed farmers don't mow their lawn regularly like a homeowner and instead let the lawn mature to the point where it can make viable seed for harvest. Most grass varieties are now hybrids, resulting in barren offspring. Grass seed heads of DNA-certified turf varieties Sir Walter Buffalo, Eureka Kikuyu, Nullarbor Couch or newly developed grass varieties are sterile.
This means they won't spread to other areas of your garden and will grow from the seeds. Seed heads in buffalo grass grow from runner or stolon. Most buffalo seeds are sterile, so the seeds cannot spread the grass. The head of the seed is often compared to asparagus, with its thicker shape and exposed seeds.
When you don't mow your lawn for a while, you may see the blades developing seed heads. Some grasses propagate well from seeds, but others have sterile seeds that do not help fill in turf bald spots. There are some downsides to letting your lawn grow long enough to sow, and it's often easier to buy seeds when you need to refill your lawn. Letting your lawn grow large enough to develop seeds is not a good idea for your lawn.
But you may now be wondering, “What are these grass seed heads that are popping up all over my garden? Like all plants, your lawn wants to reproduce. During spring, cold-season lawns will begin to use their energy and focus on sowing. Your lawn is now consuming much of your energy production and you are going to sow. Instead of using that food and energy in its roots and grass leaves, it uses the accumulated fertilizer and energy for reproduction and seed head generation.
As the cold season grass uses its energy-sprouting seeds, you'll notice a change in the overall color of your lawn. On the one hand, grass seed heads have a much lighter shade than real grass blades. This can give a pale and hazy appearance. One of the best lawn care practices is to mow your lawn frequently.
Now, when your lawn is going to sow, it's no different and maybe even more important. When you cut off the seed heads, the grass will begin to grow with a harder, more woody stem. This texture is noticeable, especially when walking barefoot. As you continue to mow, the blades on your mower will start to dull much faster.
So, have a sharp backup blade ready to prevent grass blades from breaking, which will also help prevent lawn diseases and fungi such as brown patch. The fact that the grass is going to sow (or destemming) is a natural process. You need to mow your lawn often, adjust the mowing height, and make sure that the blades on your mower are sharp, as the woody stems will start to grow back. This time of year, in spring, cold-season grasses will consume a lot of seed heads that produce energy, so be sure to feed your lawn with a well-balanced fertilizer now.
The seeds produced by cold-season grasses in spring are sterile and do not germinate. As an Amazon Associate, we earn on eligible purchases at no additional cost to you.

When these grass seed heads start to appear on the lawn, it is understandable to think that you may have weeds. It is very easy to confuse Couch seed heads with weeds, as their color varies from green to purple and they grow above the level of the lawn. Letting the grass grow until it develops seed heads doesn't always help you fill the empty spots in the lawn. Even if the seed was allowed to reach maturity, which would take about four months, allowed to dry and then harvested, you would still have to make sure that the seed would find a home in the ground to be able to germinate.
Weed seeds tend to germinate faster than lawn seeds, which can lead to larger weed problems rather than having a fuller lawn. The most common types of grass in Australia produce a sterile seed head, which means that they cannot be spread by seed in other areas of the garden and grown from the seeds, only through twigs or vegetative stolons. But what if the seed heads were not sterile and the grass could oversow? That would certainly make my job easier. Augustine (Stenotaphrum secundatum), seed not growing very tall, but seeds are not usually viable.
In the middle or late spring, cool-season grasses (Kentucky bluegrass, perennial roe, and tall fescue) will plant. Yes, even if they were not sterile, you have to let the grass grow very tall so that the seeds ripen and dry out. Ignoring the lawn so that the lawn can grow until it develops seeds, often gives weeds a chance to get stronger. The second reason for the lighter color is that, as mentioned above, lawn seed production spends most of its energy on sowing and trying to reproduce.
