Short answer: Our pick for landscapers is Fire Salt Essential Hydration: 670 mg sodium, 190 mg potassium, 90 mg magnesium and 90 mg calcium per stick, with zero sugar and 5 calories. Use one stick per hour of hard work, like hardscape, digging, sod and mulch, and plain water between properties on lighter mowing hours. OSHA lists landscaping as heavy work, and it says jobs over two hours in the heat need electrolytes.

What makes landscaping different
- Every day is a moving jobsite. Crews hop between properties, so water lives in the truck. Make the truck stop count. Refill and mix a stick at every property, not just at lunch.
- The workload swings all day. OSHA's workload table lists landscaping, shoveling and pushing wheelbarrows as heavy work, and intense digging and stone masonry as very heavy. Running mobile equipment like a ride-on mower is moderate. Match your sticks to the heavy hours, not the clock.
- Spring is the dangerous season. OSHA notes that workers lose heat tolerance over winter, and that risk jumps "when temperatures first begin to increase in the spring or early summer" and on any day much hotter than the ones before.
- Seasonal hires. Many crews add people each spring. OSHA reports that over 70% of heat-related deaths happen in a worker's first week.
A landscaping-crew day
| Stop | What |
|---|---|
| Shop, before loading | Water, and fill the truck cooler. Pre-mix one Fire Salt bottle per person. |
| Each property | Refill at the truck. One stick for each hour of hardscape, planting or digging. |
| Mow-only stretches | Water, about 8 oz every 15–20 minutes (CDC/NIOSH). |
| Lunch | Eat real food in the shade or the cab with the AC on. |
| Last property | One more stick if your shirt is soaked. |
Ramp up new and returning crew members
NIOSH recommends a 7–14 day acclimatization period. New workers start at no more than 20% of a normal day in the heat and add up to 20% each day. Experienced workers coming back start at 50% on day 1, then 60%, 80% and 100%. Do it with the same work they'll be doing, because OSHA says light work doesn't acclimatize you for heavy work.
Why Fire Salt fits a landscaping crew
- Stick packs live in the glove box. No tubs, scoops or spills in the bed of the truck.
- Zero sugar, 5 calories, so six or eight sticks across a long day don't stack up sugar.
- Magnesium and calcium, 90 mg each, with coconut water in all 11 flavors. Rotate flavors so bottle six still goes down.
- Lifters on the crew? Electrolytes + Creatine adds 5 g creatine monohydrate with the same sodium and magnesium, $58.99 for 32.
- Tested every batch by a Salt Lake City-based, ISO 17025-accredited third-party lab. See Quality & Testing.
Other options, one line each
- Liquid I.V. is easy to grab at a gas station on the route.
- Sqwincher sells to workplaces, with an industrial section on its site.
Training in a language your crew understands
OSHA notes that many landscaping workers are Hispanic, and it requires training in a language and vocabulary workers understand. That includes heat-illness training. Go over the warning signs from the CDC/NIOSH heat-related illnesses page in English and Spanish. Confusion or passing out is a 911 call. If you have high blood pressure or kidney problems, or you're on a low-sodium diet, ask your doctor before using a high-sodium product.
Buying for a landscaping company
Stock each truck for the week. See bulk orders, or start with the 32-stick box.

About one per hour of heavy work, like digging, hardscape or planting. Lighter mowing hours may only need water.
Why are spring heat waves so risky for crews?
OSHA says workers lose heat tolerance over winter, and risk rises when temperatures first climb in spring and on days much hotter than the ones before.

NIOSH recommends a 7–14 day ramp-up, starting at no more than 20% of a normal day in the heat.
