Water restriction orders are active right now across Florida, Colorado, Nebraska, Texas, and Nevada. If you're suddenly on a 1-day or 2-day weekly watering schedule, your lawn is going to look very different than it did in spring β€” and that's okay.

The goal during water restrictions isn't a green lawn. The goal is a living lawn β€” one whose roots and crowns stay alive so it snaps back when restrictions lift or rain returns.

This guide covers exactly what to do (and what not to do) during active restrictions, with specific numbers for each grass type. Survival is simpler than you think β€” but the mistakes are costly and easy to make.

Florida's SWFWMD Phase III order limits outdoor watering to one day per week through July 1, 2026 at minimum, with Tampa citations beginning April 17. Denver, Aurora, Boulder, and Colorado Springs are running two-day weekly schedules under Stage 1 and Stage 2 restrictions. Nebraska now has 100% of the state in drought, with precipitation 50% below normal. If you're reading this, your lawn is on the line. Here's how to save it.

Understand What Your Lawn Actually Needs to Survive

A lawn under water restrictions needs to keep exactly one thing alive: the crown β€” the growing point at soil level where roots and shoots meet. As long as the crown survives, the lawn recovers. If the crown dries out or rots, the grass is dead and must be replaced.

Grass blades dying back and turning brown is not damage. It's the grass voluntarily sacrificing its top growth to protect its crown in a process called summer dormancy. This is survival, not failure β€” it's the same mechanism that lets prairie grasses go 60+ days without rain and bounce right back.

The minimum amount of water needed to keep crowns alive during dormancy is much lower than most homeowners expect:

  • Bermuda grass: Β½ inch every 7–10 days
  • Zoysia grass: Β½ inch every 7–10 days
  • St. Augustine: Β½ inch every 7 days
  • Kentucky bluegrass: Β½ inch every 14 days
  • Tall fescue: Β½ inch every 14 days

None of these amounts will keep your lawn green. They will keep it alive.

According to the University of Nebraska–Lincoln Extension ( 1 ), Kentucky bluegrass crowns can survive 4 to 5 weeks of complete dormancy without supplemental water if soil moisture was adequate beforehand. The numbers above are your restriction compliance target β€” not the 1 to 1.5 inches per week you would normally apply during the growing season.

If you're not sure whether your lawn is dormant or actually dead, check the diagnostic guide first: Is my lawn dead or dormant? Treat dormant grass β€” don't waste your single watering day on grass that's already gone.

How to Get the Most Out of Your Allowed Watering Days

When you only get one watering day per week, every drop has to count. The four rules below come from decades of turfgrass research and they make the difference between a lawn that recovers and one that dies in place.

Water Early in the Morning

Water between 5 and 8 AM only. Soil is cool, so absorption is at its maximum. There's no evaporation loss from midday sun. And blades dry before evening, which prevents fungal disease.

Most Florida and Colorado restriction orders specify a morning watering window anyway β€” check your assigned hours so you stay compliant.

Watering in the evening seems sensible because it's cooler, but wet grass overnight creates the conditions for brown patch, dollar spot, and pythium. Fungal disease can kill stressed turf faster than drought ever will. If you have to choose between morning and evening, morning wins every time.

Water Deeply, Not Briefly

Your goal is to drive moisture 4 to 6 inches deep into the soil β€” not a shallow surface wetting. Shallow watering produces shallow roots, which means worse drought tolerance, faster wilting, and more damage.

To check depth, push a long screwdriver or a soil probe into the lawn 30 minutes after watering. If it slides in easily to 4 to 6 inches, you've watered enough. If it stops at 2 inches, the soil beneath is still bone-dry β€” run the sprinkler longer next time.

Use the Tuna Can Test

Place 3 or 4 empty tuna cans around the lawn during your sprinkler run. When they contain Β½ inch of water, you've applied your survival amount. Most standard oscillating sprinklers take 15 to 25 minutes to reach this depth; in-ground rotor heads take 25 to 40 minutes per zone.

For survival watering, stop at Β½ inch. Don't try to compensate for missed days by overwatering on your allowed day β€” it causes runoff, doesn't soak in as well as a slower application, and can put you over your city's per-zone duration cap.

Cycle and Soak for Clay Soils

Colorado, Texas, and parts of Florida have clay-heavy soils that water beads off when dry rather than absorbing. If you see runoff before your tuna cans are even ΒΌ full, stop. Wait 20 minutes. Then run the sprinkler again. This cycle-and-soak method gets meaningfully more water into the soil on a single allowed watering day than one continuous run does, because each pause lets the surface re-wet and soften enough to accept the next round.

Mowing During Water Restrictions

The single most important rule when your lawn is under stress: raise your mowing height.

Most homeowners want to mow short when the lawn looks bad, thinking they're "cleaning it up." This is the worst thing you can do during restrictions. Here's why:

  • Taller grass blades shade the soil. Shaded soil loses moisture 30 to 40% slower than soil exposed to direct sun.
  • Longer blades mean more photosynthesis surface, which means more energy available for the crown to maintain itself through dormancy.
  • Short-mowed dormant lawns expose the crown directly to sun and surface heat. This pushes dormancy into outright death.

Mowing heights during restrictions:

  • Bermuda: 2.5–3 inches (normally 1.5–2)
  • Zoysia: 3 inches (normally 2–2.5)
  • St. Augustine: 4 inches (normally 3–3.5)
  • Kentucky bluegrass: 4 inches (normally 3–3.5)
  • Tall fescue: 4–4.5 inches (normally 3.5–4)

How often to mow: Dormant grass grows slowly or not at all. Check weekly but only mow when the grass has visibly elongated past your target height. Under severe restrictions you may only need to mow once every 2 to 3 weeks. Never remove more than one-third of the blade in a single cut β€” this is the standard one-third rule and it matters more under stress, not less.

Blade sharpness: A dull blade tears grass tissue rather than cutting it cleanly, leaving jagged edges that lose water and invite disease. Sharpen your mower blade now if you haven't already this season.

Leave clippings on the lawn when you do mow. Mulched clippings return organic matter and nitrogen to the soil and retain surface moisture β€” exactly what a stressed lawn needs.

What to Skip Completely

These are the mistakes that turn dormant lawns into dead ones. None of them is helpful during a restriction period β€” every single one accelerates damage.

1. Skip fertilizing. Fertilizer, especially nitrogen, pushes new growth. New growth demands water. Water-stressed grass cannot support new growth. You will cause more damage than you prevent. Wait until the lawn has been green and actively growing for 3 weeks before any feeding. No exceptions.

2. Skip aerating. Aeration is a tool for actively growing turf. Aerating dormant grass simply opens channels for the remaining moisture in your soil to escape faster, while putting mechanical stress on already-weakened crowns. Wait until recovery is complete. Find the best aeration window for your city β†’

3. Skip dethatching. Same reasoning. Counterintuitively, the thatch layer is actually insulating the crown during drought. Power-raking it off now removes that insulation right when the lawn needs it most. Remove thatch after recovery, not during.

4. Skip weed-and-feed products. These combine fertilizer and herbicide in a single application β€” see #1. The fertilizer component stresses drought-weakened turf, and broadleaf herbicides further weaken plants under heat stress. Apply selective weed control separately, and only after the lawn is actively growing again.

5. Skip pest treatments unless you actually see active damage. Many pesticides require watering in after application β€” water you may not legally have. Hold off unless an outbreak is visible. Chinch bugs and grub damage do show up under drought, but treat only if you confirm them.

6. Skip topdressing and seeding. New seed and tender seedlings need water you cannot legally provide. Wait until the lawn is actively growing again and restrictions have lifted before any soil amendments or overseeding work.

Restrict-Period Watering by Grass Type β€” Quick Reference

Different grasses tolerate restrictions very differently. Use this table to know what to expect for your specific lawn.

Grass Type Frequency Per Session Stress Visible Recovery
Bermuda (Dallas, Houston, Atlanta, Phoenix) Every 7–10 days Β½ inch 14 days no water 7–10 days
Zoysia (Atlanta, Charlotte, transition zone) Every 7–10 days Β½ inch 10–14 days 14–21 days
St. Augustine (Florida, Gulf Coast) Every 7 days ½–¾ inch 7 days 10–14 days
Kentucky bluegrass (Colorado, Nebraska, Midwest) Every 14 days Β½ inch 7–10 days 14 days fall / 3–4 weeks summer
Tall fescue (transition zone, Southeast) Every 14 days Β½ inch 14 days 14–21 days

Notes by grass type:

  • St. Augustine is the most sensitive of the warm-season grasses. Its crowns sit above the soil surface (stoloniferous growth), so they dry out faster than Bermuda or zoysia. Risk of permanent loss is real if you skip a watering window in peak heat.
  • Kentucky bluegrass has the most reliable summer dormancy of any cool-season grass. It will brown completely and look dead, then green up perfectly in fall. Don't panic β€” at typical Denver and Front Range soil temperatures, the crowns are alive and waiting.
  • Tall fescue has deeper roots than Kentucky bluegrass β€” up to 36 inches in mature stands β€” and tends to handle restrictions better as a result. If you're in the transition zone and choosing a new lawn, tall fescue is the smarter pick under recurring drought.
  • Bermuda and zoysia are the most drought-tolerant lawn grasses sold in the US. They evolved in dry climates and can hold dormancy for 4 to 6 weeks without measurable harm to the crown.

The University of Kentucky Cooperative Extension ( 2 ) confirms that established cool-season turf can recover from 30 to 60 days of complete dormancy without long-term damage β€” provided you keep the crowns hydrated at the minimum schedule above.

Check Your Specific Restrictions Before You Water

Not all restriction orders are alike. Before setting your sprinkler controller, confirm four things for your address:

  • Your assigned watering days (usually by address ending or odd/even date)
  • Allowed time windows (most cities require before 8 AM or after 6 PM)
  • Maximum duration per zone (some cities cap at 1 hour total)
  • Citation amounts and enforcement dates for non-compliance

Florida's Tampa-area citations start at $158 for a first violation as of April 17, 2026, and rise quickly with repeats. Denver Water is issuing immediate citations with no warning period in some neighborhoods this season. The fines outweigh the cost of any lawn damage you'd prevent by overwatering.

Find your city's exact rules:

When Will Restrictions Lift? Planning Ahead for Recovery

Florida: SWFWMD Phase III restrictions run through July 1, 2026 at minimum. They may extend if the wet season is late arriving β€” Florida's rainy season typically begins late May to early June, but a 2- to 3-week delay isn't unusual in drought years. Once meaningful rain returns, your lawn will begin recovering naturally even before the order is officially lifted.

Colorado: The 2026 drought outlook for the Front Range is severe. According to Colorado State University Extension ( 3 ), 2026 reservoir levels and snowpack are well below historical averages. Denver, Aurora, and Colorado Springs restrictions are not expected to lift before mid-summer, and may persist into fall. Kentucky bluegrass lawns will likely resume normal watering only when temperatures cool in September and October, when fall growth begins naturally.

Recovery plan β€” start preparing now. When restrictions lift or rainfall returns, the worst thing you can do is fertilize immediately. Give the lawn 2 to 3 weeks to confirm recovery first. Then:

  • Week 1–2: Resume normal deep watering β€” about 1 inch per week including rainfall.
  • Week 3: First light fertilizer application, slow-release only.
  • Week 4–6: Walk the lawn and identify dead patches. Plan an overseed for the next active growth window.
  • Fall (cool-season) or late spring (warm-season): Core aerate and overseed thin or dead areas to restore density.

Frequently Asked Questions

Can I water every day in small amounts instead of deep watering on my allowed days?

Under most restriction programs, no β€” your watering days and times are fixed by your address. But even if you could, daily shallow watering is worse than deep watering on allowed days. Shallow watering keeps only the top inch moist, encouraging shallow roots that dry out faster between sessions. Deep, infrequent watering drives roots downward to where soil stays moist longer. Your restriction is actually forcing you into the better practice.

My neighbor is ignoring the restrictions and their lawn looks green. Should I do the same?

No. Florida citations start at $158 and reach $500+ per violation as of April 17, 2026. Colorado municipalities are issuing immediate citations with no warning period in some areas. One fine outweighs the cost of reseeding any drought-damaged areas. And here's the part most people miss: your neighbor's lawn won't actually look better six months from now. Yours will recover just as well in fall β€” and you won't have a citation on file with the water utility.

My lawn has a sprinkler system β€” how do I set it to comply?

Program your controller to run only on your allowed watering day(s), within your allowed time window (usually 5 to 8 AM), and set each zone to run until the tuna-can test shows Β½ inch collected. Disable any "missed cycle" or "make-up" features so the system never runs on a non-approved day. Smart controllers like Rachio and RainBird can be set to specific calendar days and will auto-skip if their weather data shows recent rainfall β€” both features become essential under restrictions.

It rained last week. Does that count as my watering day?

If you received Β½ inch or more of rainfall, your lawn got its survival water for the week and you don't need to supplement on your assigned day. Use a rain gauge or a tuna can to measure actual rainfall β€” local forecasts often miss what fell on your specific lawn. Most restriction orders include a rain skip provision, so you won't be cited for not watering when it rained adequately.

My lawn has a brown patch shaped like a circle about 3 feet across. Is this drought or disease?

Circular patches are a disease red flag. Drought causes even, uniform browning across the entire lawn β€” not isolated circular spots. Likely culprits: brown patch fungus (very common in Florida summer heat and humidity), dollar spot, or fairy ring. Treat the disease first β€” extra watering will not fix it and may actually worsen brown patch. According to Colorado State University Extension ( 3 ), drought-stressed lawns are more vulnerable to fungal disease, so disease and dormancy frequently appear at the same time. A targeted fungicide application may be needed.

When can I start fertilizing again after restrictions lift?

Wait 3 weeks after your lawn has fully greened up and is actively growing before any fertilizer. Rushing nitrogen onto recovering turf causes a growth surge that stresses roots that haven't yet fully re-established themselves β€” you'll trade short-term color for long-term damage. Use a slow-release formula only for the first post-restriction application. See our fertilizer timing guide for the exact rate by grass type and region.
