About the Rhode Island Yard Calendar
Caring for an Ocean State lawn requires understanding our unique coastal microclimates. Northwest Rhode Island (Burrillville, Foster, Glocester) sits in USDA Zone 6b with a crisp 160-day growing season, while Aquidneck Island and South County coastal towns thrive in Zone 7a with over 200 frost-free days.
Use our 4 dedicated sub-guides above to plan your lawn mowing, seeding, aeration, and winterization around official NOAA normals and Rhode Island environmental statutes.
Frequently Asked Questions
When should I stop fertilizing my lawn in Rhode Island?
Rhode Island statutory environmental law prohibits nitrogen fertilizer applications after October 15 to protect the Narragansett Bay watershed from toxic nutrient runoff.
What is the best month to plant grass seed in Rhode Island?
September is the premier month. Soil remains warm from summer (around 65°F to 70°F), cool autumn night air prevents heat stress, and fall rainfall nurtures germination.
When does the ground thaw in Rhode Island for spring lawn care?
In Rhode Island, the spring ground thaw occurs between April 10 and April 28 depending on your town. Coastal towns thaw about 2 weeks earlier than northwest inland towns.
When should irrigation sprinkler systems be blown out in RI?
All underground sprinkler pipes must be blown clear with high-volume compressed air before November 15, when sustained ground freezes risk bursting backflow assemblies.
What is the proper mowing height for Rhode Island grass?
Mow at 3.0″ in spring, raise deck to 3.5″–4.0″ in July/August to shade root systems, and lower to 2.5″ for your final cut in November to prevent winter snow mold.
