Weed State and Local Guidelines/Policy

Massachusetts State Fertilizer Regulations:

Under Massachusetts 330 CMR 31.00 and GL 128 § 65A, here are the key rules for non-agricultural lawns:

1. • Phosphorus fertilizer is allowed only if a soil test (no older than 3 years) shows it’s needed, or you’re establishing/renovating a lawn (only in the first season).

     Phosphorus‑Only If Needed:

2. • No fertilizer application from December 1 to March 1, or on frozen, snow‑covered, saturated, or flood‑prone soils.

     Seasonal Ban:

3. • 20 ft for broadcast spreaders
   • 10 ft for drop/targeted spreaders

     Waterbody Setbacks:

4. • No application on driveways, sidewalks, etc. Any spills must be cleaned up and disposed of properly.

     Prohibited on Impervious Surfaces:

5. • Soil tests valid for 3 years and required for phosphorus use. Professional applicators must keep records (product, date, area, rates, soil test, etc.) for 3 years.

     Soil Testing & Record‑Keeping:

6. • Stores must clearly separate phosphorus fertilizers and display warning signs about runoff risks.

     Retailer Signage:

7. • Violations can result in fines: $250 (1st), $500 (2nd), $1,000/day (subsequent).

     Penalties:

Per the Sturbridge Wetlands Bylaw/Conservation Commission (via eCode360 & town regs PDFs):

• No fertilizers, pesticides, herbicides, salts, etc., within 200 ft of any resource area (wetlands, lakes, streams), unless applied by a Massachusetts state-licensed applicator.

• While not mandatory, the Town recommends maintaining buffer zones or natural vegetation to help filter runoff.

Best Practices (Echoing Both State & Local Guidance):

• Don’t use fertilizer at all but if you choose to: Use phosphorus-free fertilizers unless a soil test says it’s needed.
• Avoid frozen/saturated/snow-covered ground or heavy-rain forecasts.
• Observe 10–20 ft setbacks and 200 ft buffer zones near water.
• Maintain or restore natural buffers along the shoreline.
• Report and Clean up spills immediately on hard surfaces.
• Use carefully—only as needed based on testing and turf health.
