Palmetto Rain Community
Since launching June 25, 2026, South Carolina yards have saved together:
Gallons Saved
Money Saved
Sessions Rainfall Covered
Inches of Rainfall Tracked
We count a sprinkler session as saved when rainfall alone provides as much water as that session would have. Clemson HGIC recommends one to two deep sessions a week, so every one rain covers is a real saving.
How It Works
Enter Your ZIP Code
We use your ZIP to find the nearest NOAA weather station and pull real precipitation data for your area, updated every day.
Build Your Plant List
Choose from 170 plants across grasses, natives, shrubs, herbs, vegetables, flowers, and fruit trees. Each one has its own water needs factored into every recommendation.
Get Your Daily Watering Email
Every morning you get one clear message: water today, or skip it. Nothing else to think about.
Stay on Top of Fertilizing
On the first of every month, we tell you exactly which plants in your yard need feeding, how often, and what to use, including organic alternatives.
Track Your Impact
Watch your gallons saved grow over time. See your full water history, rainfall totals, and how much your yard is saving compared to running sprinklers on a fixed schedule.
Features
Real Local Rainfall
We pull live precipitation data from NOAA weather stations, the same ones the National Weather Service uses. Your recommendation is based on what actually fell on your yard, not a regional estimate.
Smart Watering Recommendations
Every morning you get one clear answer: water today, or let nature handle it. Palmetto Rain does the math on rainfall, your plants' needs, and the forecast so you never have to.
A Plant Library for South Carolina
Browse 170 plants with full growing guides, companion planting suggestions, wildlife habitat info, and South Carolina-specific tips. Not generic advice. Advice written for our climate.
Monthly Fertilizer Reminders
On the first of every month, we tell you exactly which plants in your yard need feeding, how often, and what to use, including organic alternatives for every plant.
Water Savings You Can See
Track every gallon your yard saves. Watch your rainfall coverage grow week over week and see exactly how much nature is doing the work instead of your sprinkler.
Built for South Carolina
Palmetto Rain was built specifically for coastal South Carolina, where summers are brutal, rain comes in storms, and native plants are worth protecting. This is not a national app with a ZIP code field.
