How often should I water my lawn in Tallahassee?

During summer (June-September), water your Tallahassee lawn 2-3 times per week, applying 0.5-0.75 inches per session. The best time to water is between 4 AM and 8 AM. During spring and fall, reduce to 1-2 times per week. In winter, water only during dry spells — every 10-14 days is usually sufficient. Note that Tallahassee follows Northwest Florida Water Management District guidelines, which may restrict watering to specific days.

What height should I mow my grass in Tallahassee?

For St. Augustine grass (the most common in Tallahassee), mow at 3.5-4 inches. For Zoysia, mow at 1.5-2.5 inches. For Bermuda, mow at 0.5-1.5 inches. Never cut more than one-third of the blade height in a single mowing. Mowing too short (called scalping) stresses the grass and invites weeds and disease.

When should I fertilize my lawn in Tallahassee?

The ideal fertilization schedule for Tallahassee lawns is: first application in mid-March to early April (when grass starts actively growing), second in late May to early June, third in July or August (optional, light application), and fourth in September. Do not fertilize between November and February — the grass is dormant or semi-dormant and cannot use the nutrients. Use a slow-release nitrogen fertilizer for best results.

How do I get rid of chinch bugs in my Tallahassee lawn?

Chinch bugs are the number one lawn pest in Tallahassee. Signs include irregular yellow-brown patches that expand in hot, sunny areas near driveways and sidewalks. To check, push a metal can (both ends removed) into the soil in the transition zone between dead and live grass, fill with water, and watch for tiny black-and-white insects floating up. Treat with bifenthrin or imidacloprid insecticide. Preventive applications in May and July are recommended for St. Augustine lawns.

Why is my Tallahassee lawn turning yellow?

Yellow grass in Tallahassee can indicate several issues: iron deficiency (common in our alkaline-leaning areas — treat with iron sulfate), nitrogen deficiency (apply slow-release fertilizer), overwatering (reduce frequency and check drainage), chinch bug damage (check for insects at the edge of yellowing areas), or fungal disease like gray leaf spot or brown patch. A soil test from the UF/IFAS Leon County Extension Office ($7) will identify nutrient deficiencies.

10 Essential Lawn Care Tips for Tallahassee Homeowners

Homeowner maintaining a well-manicured lawn in Tallahassee neighborhood

Maintaining a beautiful lawn in Tallahassee is not the same as maintaining a lawn in Atlanta, Dallas, or even Jacksonville. Our specific combination of sandy soil, acidic groundwater, brutal summer humidity, and occasional winter freezes creates unique challenges that require local knowledge — not generic advice from a national lawn care website.

These 10 tips come from more than two decades of installing and maintaining lawns across Leon County and the Big Bend region. They are the same recommendations we give to every customer after completing a sod installation.

1. Mow at the Right Height (And Never Scalp)

Mowing height is the single most impactful thing you control about your lawn's health, and it is the tip most Tallahassee homeowners get wrong.

Correct mowing heights for Tallahassee:

St. Augustine: 3.5-4 inches
Zoysia: 1.5-2.5 inches
Bermuda: 0.5-1.5 inches
Bahia: 3-4 inches

The one-third rule is non-negotiable: never cut more than one-third of the blade height in a single mowing. If your St. Augustine is at 6 inches (common after a week of summer rain), you need to mow it down to 4 inches — not all the way to 3 inches. Scalping removes the energy-producing leaf surface, exposes soil to direct sunlight (which promotes weed germination), and sends the grass into stress recovery mode instead of healthy growth.

If you have fallen behind on mowing, bring it down in stages over two or three mowings rather than one aggressive cut.

2. Water Deeply and Infrequently

The most common watering mistake in Tallahassee is watering a little bit every day. This trains your grass roots to stay shallow — they never need to grow deep because water is always available at the surface. Then the first week you skip watering (or your sprinkler system breaks), those shallow roots cannot reach deeper moisture and the lawn dies.

The correct approach: Water 2-3 times per week during summer, applying 0.5-0.75 inches per session. This is enough to soak the top 6-8 inches of soil, encouraging deep root growth. Between waterings, the soil surface should dry out slightly.

How to measure: Place several tuna cans or straight-sided containers around your lawn, run your sprinklers, and check how long it takes to collect 0.5 inches of water. For most irrigation systems in Tallahassee, this takes 20-40 minutes per zone.

Best time to water: Between 4 AM and 8 AM. This gives the grass time to absorb water before the heat of the day while allowing the blades to dry by mid-morning, which reduces fungal risk. Avoid watering in the evening — wet grass overnight is an invitation for disease.

3. Follow a Fertilization Calendar

Tallahassee's growing season runs from mid-March through early November. Your fertilization schedule should align with the grass's active growth periods. Here is the calendar we recommend for St. Augustine and Zoysia lawns:

Mid-March to Early April (Spring Wake-Up): Apply a balanced slow-release fertilizer like 15-0-15 or 16-4-8 at the rate on the bag. This feeds the grass as it comes out of winter dormancy and starts active growth.
Late May to Early June (Summer Boost):Apply a nitrogen-heavy slow-release fertilizer. Avoid high-phosphorus fertilizers unless a soil test indicates a deficiency — excess phosphorus runs off into Tallahassee's lakes and waterways.
July to August (Optional Mid-Summer): A light application of iron-only supplement (like Ironite) gives the lawn a deep green color boost without stimulating excessive growth during the hottest weeks. Skip this if your lawn is already growing vigorously.
September (Fall Prep): Apply a potassium-heavy fertilizer (the third number on the bag) like 0-0-25 or 15-0-15. Potassium strengthens cell walls and helps the grass resist cold stress during winter.
November through February (No Fertilizer): The grass is dormant or semi-dormant. Fertilizer applied during this period is wasted — the roots cannot absorb it, and it will leach into the groundwater or wash off in winter rains.

4. Control Weeds Before They Spread

Weed management in Tallahassee is a year-round job because our mild winters never fully kill warm-season weeds, and cool-season weeds germinate in fall and winter.

Pre-emergent herbicide is your most powerful tool. It prevents weed seeds from germinating in the first place. Apply in:

Late February to early March: Targets summer annuals like crabgrass, goosegrass, and spurge before they germinate.
Late September to early October: Targets winter annuals like annual bluegrass (Poa annua), henbit, and chickweed.

Post-emergent herbicide targets weeds that are already growing. For broadleaf weeds in St. Augustine (like dollarweed, clover, and oxalis), use a product containing atrazine. Apply when daytime temperatures are below 85 degrees — atrazine can damage St. Augustine in high heat.

The best weed control is a thick, healthy lawn. Dense grass shades the soil, preventing weed seeds from getting the sunlight they need to germinate. If your lawn is thin enough for weeds to take hold, the underlying issue is usually something else — mowing too short, inadequate fertilization, or pest damage.

5. Monitor for Chinch Bugs (Seriously)

If you have a St. Augustine lawn in Tallahassee, chinch bugs are your biggest threat. Period. These tiny insects (adults are about 1/5 inch long, black with white wings) suck the sap from grass blades, injecting a toxin that kills the tissue. Damage appears as irregular yellow-brown patches that start in hot, sunny areas — typically along driveways, sidewalks, and south-facing edges of the lawn.

Peak chinch bug season in Tallahassee is June through September. Damage accelerates during hot, dry periods.

How to check: Cut both ends off a coffee can. Push one end 2-3 inches into the soil at the edge of a yellowing patch (the transition zone between damaged and healthy grass). Fill the can with water and wait 5 minutes. If chinch bugs are present, they will float to the surface. You will see tiny black insects with distinctive white X-shaped wing patterns.

Treatment: Apply a lawn insecticide containing bifenthrin (Talstar) or imidacloprid. Water it in lightly after application. For severe infestations, professional treatment ensures proper coverage and dosage.

Prevention: Two applications of preventive insecticide in May and July will keep chinch bug populations below damaging levels for most Tallahassee lawns. Zoysia lawns are naturally resistant and rarely need chinch bug treatment — one of the reasons Zoysia is gaining popularity in our area.

6. Manage Mole Crickets in Sandy Soil

Mole crickets are the second most destructive lawn pest in the Tallahassee area, and they thrive in our sandy soil. Unlike chinch bugs that damage grass from above, mole crickets tunnel through the top 1-2 inches of soil, severing roots and creating visible tunneling ridges on the surface.

Signs of mole cricket damage:

Spongy, soft spots in the lawn that feel hollow underfoot
Raised ridges or small mounds of soil on the surface
Irregular brown patches where roots have been severed
Birds (especially mockingbirds and grackles) actively feeding on your lawn — they are eating the mole crickets

Treatment timing: The best time to treat mole crickets in Tallahassee is late June through July, when the nymphs (juveniles) are small and near the surface. Adult mole crickets tunnel deeper and are harder to reach. Apply a granular insecticide containing bifenthrin or use a bait product containing indoxacarb in the evening (mole crickets are most active at night).

7. Adjust Your pH With Lime

Leon County soil commonly tests between 5.5 and 6.5 pH, which is on the acidic side of the range preferred by most warm-season grasses (6.0 to 7.0). Acidic soil locks up essential nutrients like calcium, magnesium, and phosphorus, making them unavailable to your grass even if they are present in the soil.

If a soil test shows your pH is below 6.0, apply pelletized dolomitic lime at 40-50 pounds per 1,000 square feet. Dolomitic lime also adds magnesium, which is frequently deficient in North Florida sandy soil.

When to apply: Fall (October-November) is the best time. Lime takes 4-8 weeks to measurably affect soil pH, so a fall application ensures the pH is adjusted by the time spring growth begins. You can also apply in early spring (February-March) if needed.

How often:Retest your soil every 2-3 years. One lime application typically holds pH in the target range for 2-4 years in Tallahassee's sandy soil.

8. Sharpen Your Mower Blades

This sounds like minor maintenance advice, but dull mower blades cause real problems. A sharp blade makes a clean cut that heals quickly. A dull blade tears and shreds the grass, leaving ragged tips that:

Turn brown and white at the ends (giving the lawn a hazy, brownish cast within 2-3 days of mowing)
Create entry points for fungal diseases like gray leaf spot
Increase water loss through damaged tissue
Stress the plant, making it more vulnerable to pests

Sharpen or replace your mower blades every 20-25 hours of use — roughly every 8-10 mowings for most Tallahassee homeowners. If you mow weekly from April through October (about 30 mowings), that means sharpening 3-4 times per year. Most local hardware stores and mower shops sharpen blades for $8-$15.

9. Leave Grass Clippings on the Lawn

Unless you are dealing with a disease outbreak, leave your grass clippings on the lawn after mowing. This practice (called "grasscycling") returns nitrogen, phosphorus, and potassium back to the soil as the clippings decompose — the equivalent of one free fertilizer application per year.

Contrary to popular belief, grass clippings do NOT cause thatch buildup. Clippings are about 85% water and decompose within 1-2 weeks. Thatch is caused by the buildup of stems, stolons, and roots — not clippings.

The only time to bag clippings is when the lawn is diseased (to prevent spreading fungal spores) or when you have fallen behind on mowing and the clippings are so heavy they smother the grass underneath.

10. Prepare Your Lawn for Each Season

Tallahassee has four distinct lawn care seasons, and each requires different focus areas:

Spring (March - May)

Apply pre-emergent herbicide in late February or early March
First fertilizer application when grass starts actively growing
Start regular mowing schedule (weekly during active growth)
Increase irrigation to 2 times per week
Check for winter damage and overseed or patch bare spots

Summer (June - September)

Monitor for chinch bugs weekly in hot, sunny areas
Water 2-3 times per week (or as needed based on rainfall)
Mow weekly, never removing more than one-third of blade height
Apply second fertilizer application
Watch for fungal diseases during humid spells
Treat for mole crickets in late June or July

Fall (October - November)

Apply pre-emergent for winter weeds (late September or early October)
Final fertilizer application (potassium-heavy)
Apply lime if soil test indicates low pH
Reduce irrigation to 1 time per week
Continue mowing but reduce frequency as growth slows
Ideal time for new sod installation if needed

Winter (December - February)

Reduce mowing to every 2-3 weeks or as needed
Water only during extended dry spells (every 10-14 days)
Do NOT fertilize — grass is dormant or semi-dormant
Avoid heavy foot traffic on dormant grass

Bonus: Know When to Call a Professional

Most of these tips are things you can do yourself. But there are situations where professional help saves you time, money, and frustration:

Large dead patches that do not respond to watering and fertilization (likely pest or disease issue requiring diagnosis)
More than 50% of your lawn is weeds — at that point, removing the old lawn and installing fresh sod is faster and more cost-effective than trying to rehabilitate it
Drainage issues that cause standing water for more than 24 hours after rain
Irrigation system problems — uneven coverage, broken heads, or controller issues that need repair
