Is your grass flowering? If so, follow these tips to keep your lawn healthy.
At some point during the spring season it’s very likely you’ll notice some flower heads forming along the top portion of your lawn. This can lead to a lot of confusion among do it yourselfers, especially if you’ve been properly maintaining your lawn. I usually get a steady wave of questions related to “Why is my grass flowering?”, from late May to mid June.
The answer is simple… It’s completely normal, and also temporary!
As much as I’m a perfectionist when it comes to my lawn, I’ve trained myself to accept this brief 3-4 week period when my grass is flowering. But, that’s not to say I don’t do what I can to minimize these unsightly flowers.
Let’s take a look at why your grass flowers and what you should do about it…
Why Does Your Grass Flower?
The reason your grass flowers is pretty simple. Your lawn is just like so many other plants in your landscape. In order to reproduce, it forms a flower, and then seed. In a naturally occurring situation, this seed eventually drops into the soil and grows into more grass. This is the way mother nature intended it to be.
But, chances are the lawn you maintain on your property doesn’t really fit into a ‘naturally occurring’ situation. More on this later (see section ‘Should You Let Your Lawn Go to Seed).
What To Do About Your Flowering Lawn
1. Mow High and Often- Resist the urge to mow low to try and chop off the flowers on your blooming lawn. Doing so will only stress your lawn more. Instead, mow high, and often. This is your best bet to minimize flower production.
2. Feed Your Lawn!- This is so important. When your lawn is producing flowers (going to seed) it uses a ton of energy. There’s no doubt it will be at a weakened state and will be more susceptible to natural stressors such as fungus, dry weather, heat, etc. This is a great time to feed your lawn with a healthy does of nitrogen. Nitrogen will actually help shift some of the focus back on blade growth instead of seed production.
A fertilizer such as Flagship 24-0-6 is a great choice for when your grass is flowering. It is rich in nitrogen (24%) and also contains some Potassium (6%), but the middle number Phosphorus is 0%. Phosphorus is most responsible in seed development and flowering which we are trying to prevent, so having that zeroed out during this time is a good thing.

Just note, the Flagship 24-0-6 is just one suggestion. Don’t think you have to make a special purchase or steer off from the lawn care plan you have mapped out. Any fertilizer rich in Nitrogen is a good choice for a lawn that is flowering.
3. Keep Mower Blades Sharp- Your blades are cutting through a lot at this point in the season. Thick grass blades, thick stalks, and now flowers. This is a great time to get a good clean edge on your mower blade.
Should You Let Your Lawn Go to Seed?
It sounds like a brilliant plan doesn’t it. Just let your lawn go to seed and you’ll get beautiful, free grass seed and your lawn will naturally thicken up without you lifting a finger.
Of course, that awesome plan won’t work at all. You see, almost all grass seed you get these days is a hybrid. In other words it’s been genetically modified and the seed that the genetically modified grass produces is not viable. This seed is either sterile or will produce grass that is very different (and less strong and attractive) than the grass the seed came from.
Brown Tips On Grass Blades
During the weeks when your lawn is flowering, and ultimately going to seed, you may notice the tips of your grass blades look brown. What you’re most likely seeing is the seeds at the top of the grass stalks. As the seeds turn more of a tan color as seed production slows, you may notice brown “tips” throughout your lawn, even after a fresh mow. Again, this is normal and temporary.
Make sure your mower blades stay sharp at this time so you can be sure that the brown tips on your grass is actually from the seeds and not from a dull blade.
