Key Takeaways
- Dollar spot shows up as small tan or straw-colored circles about silver-dollar size, and hourglass-shaped lesions with reddish-brown borders on individual blades confirm it.
- Look for white, cottony growth on grass early in the morning when dew is heavy; it fades as the day heats up, making it a key early clue.
- Keep mower blades sharp, never cut Bermuda too short, and follow the one-third rule, since dull blades and scalping create entry points for the fungus.
- Water early in the morning and deeply rather than lightly or at night, so blades dry quickly and stay less vulnerable to fungal growth.
You walk out on a warm Riverview morning, coffee in hand, and spot it. Small, tan circles about the size of a silver dollar are dotting your once-perfect lawn. If you have Bermuda grass, you may be looking at bermuda grass dollar spot, one of the most common lawn diseases in Florida. Do not panic! You are not alone, and this problem is very manageable.
Many busy homeowners, new homeowners, and seniors in our area ask us the same thing: what causes these spots, and how do I get rid of them? The good news is that most cases come down to a few simple lawn habits. Mowing, watering, and cleanup all play a big role.
In this guide, we will walk you through what dollar spot is, why Riverview's weather invites it, and how to prevent it. We will also be honest about which fixes we handle and which ones need a specialist. Let's get your lawn looking sharp again.
What Is Bermuda Grass Dollar Spot?
Dollar spot is a lawn disease caused by a fungus. On Bermuda grass, it shows up as small, round, straw-colored patches. Each patch is often about the size of a silver dollar, which is how the disease got its name.
When many spots grow close together, they can merge into larger, uneven dead-looking areas. Your lawn may look patchy and thin. The good news is that dollar spot usually attacks the leaf blades, not the roots, so the grass can often recover.
How to Spot It Early
Look closely at the grass blades. Here are the classic signs:
- Small tan or bleached circles, about 1 to 2 inches wide on closely mowed turf
- Hourglass-shaped lesions on individual grass blades, with a reddish-brown border
- White, cottony growth on the grass early in the morning when dew is heavy
- Sunken, uneven patches that spread over a few weeks
That white, web-like fuzz is a big clue. You will usually see it at sunrise, and it fades as the day heats up.
Why Does Dollar Spot Show Up in Riverview?
Riverview has warm days, humid air, and heavy morning dew. Those are the exact conditions this fungus loves. Add a few other stressors, and your Bermuda lawn becomes an easy target.
Here is a quick look at the main triggers and what they mean for your yard:
Trigger | Why It Helps the Fungus | What You Can Do |
|---|---|---|
Long, wet mornings | Moisture sits on the blades for hours | Water early so grass dries fast |
Mowing too short | Stresses the grass and weakens it | Follow the right Bermuda height |
Dull mower blades | Torn tips make easy entry points | Keep blades sharp |
Heavy thatch buildup | Holds humidity near the soil | Mow regularly and remove clippings when needed |
Drought stress | Weak grass cannot fight disease | Give deep, steady watering |
Low soil nutrition | Thin turf struggles to recover | Talk with a local soil specialist |
Notice how many of these come down to daily lawn habits. That is why a steady, professional mowing routine matters so much.
How Mowing Habits Affect Dollar Spot
Mowing is one of the biggest things you can control. When Bermuda grass is cut too short or with a dull blade, it becomes stressed. Stressed grass catches diseases much more easily.
A sharp blade makes a clean cut. A dull blade rips the grass, leaving rough, frayed tips. Those torn edges give fungus a perfect doorway. If you are curious about mower tools, here is a simple look at how a lawn mower works and why blade type matters.
Smart Mowing Tips for Bermuda Grass
- Keep your blades sharp, and have them checked often during growing season.
- Do not scalp the lawn. Cut Bermuda at a healthy, steady height for your yard.
- Follow the one-third rule, which means never removing more than one-third of the blade at once.
- Mow when the grass is dry, not soaking wet, to avoid spreading the fungus.
- Vary your mowing pattern so you do not stress the same strips every week.

Watering the Right Way to Slow Dollar Spot
Water is a double-edged sword. Too little water stresses the grass, and too much keeps the blades damp. Both can invite dollar spot.
The best fix is a simple one: water deeply and less often, and do it early in the morning. Early watering lets the sun dry the blades quickly. Watering at night is a common mistake because the grass stays wet for hours.
- Water in the early morning, before the sun gets strong
- Soak the soil deeply instead of giving daily light sprinkles
- Skip watering after heavy Florida rain storms
- Check your sprinklers for broken heads or uneven spray

What a Professional Mowing Service Can Do
At All Trusted Lawn Care, we focus on professional lawn mowing and maintenance. That means we handle the habits that keep Bermuda grass strong and less likely to get sick. Busy families and seniors in Riverview often tell us they love not having to worry about this part.

What About Fertilizer and Treatments?
Here is where we want to be upfront and honest with you. Dollar spot is a fungal disease, and treating it often involves fungicide, fertilizer, or soil work. Our team focuses on mowing and lawn maintenance, so we do not provide fertilization, weed control, pest control, aeration, or soil care.
The good news is that we are happy to connect you with trusted local partners who specialize in those areas. Many Riverview homeowners use a two-step approach. A specialist handles any treatments, and we keep the lawn mowed and maintained so the grass can bounce back.
Bermuda grass also tends to recover well when it gets proper care. Thin spots fill in as the turf grows, as long as the stress factors are under control.
Prevention Checklist for Riverview Homeowners
Prevention is far easier than recovery. Use this simple list throughout the growing season:
- Mow on a regular schedule so the grass never gets overgrown.
- Keep mower blades sharp and avoid cutting too low.
- Water early and deeply, never at night.
- Clear leaves, debris, and heavy clippings from the lawn.
- Improve airflow by trimming back hedges and low branches that block sun.
- Watch for early spots and act fast before they spread.
If your yard also needs a cleanup before the season starts, our lawn maintenance services can help set the stage for a healthier lawn.
Dollar Spot vs. Other Lawn Problems
Not every brown patch is dollar spot. Dog urine, dull mower blades, drought, and other lawn issues can look similar at first glance. Knowing the difference saves you time and money.
Problem | What It Looks Like | Key Clue |
|---|---|---|
Dollar spot | Small tan circles, silver dollar size | Hourglass lesions on blades, white web in the morning |
Dog urine spots | Brown patches with a dark green ring | Located where pets frequent |
Drought stress | Grayish, dry, wilting grass | Footprints stay visible on the lawn |
Scalping | Brown, stubbly areas after mowing | Happens right after a cut that was too short |

A: It shows up as small, tan or straw-colored circles about the size of a silver dollar. Look closely at the blades for hourglass-shaped marks, and check early in the morning for a white, cottony web. It is easy to catch once you know what to look for!
Q: Can bermuda grass recover from dollar spot?
A: Yes, in most cases it can. Dollar spot usually attacks the leaf blades instead of the roots, so healthy Bermuda grass often fills back in with good mowing, watering, and care. Fixing the stress that caused it is the key.
Q: Does mowing too short cause dollar spot?
A: It can definitely play a part. Cutting Bermuda too short or using dull blades stresses the grass and makes it easier for fungus to take hold. Sharp blades and a steady, proper cutting height go a long way.
