Guidance for Today, October 10, 2026
Based on data as of October 9, 2026 — not today Mowing guidance below also factors in today's real-time rain and temperature.
13°F above normal for October 9 (61°F historical average high).
Turf is in active growth - at this rate, expect to mow every 5-6 days. Never remove more than 1/3 of the blade height in a single cut.
Past NDSU Extension's recommended fall fertilizer window (by end of September) - applying now risks stimulating growth right before winter, which can cause winterkill. Wait until next year.
Crabgrass pre-emergent is a spring job - nothing to do until next year. NDSU Extension: apply when 4-inch soil temps reach about 50°F, usually mid-April to mid-May.

Mowing guidance above is frequency-based (how often, given current growth conditions and recent rain) - not a measurement of your actual grass height. Pre-emergent timing is keyed to Fargo's real soil temperature; fertilizer timing follows NDSU's Memorial Day / Labor Day calendar, adjusted for whether the lawn is actually growing.
Past days use NDAWN's real observed data. Future days use NOAA's real forecast (dashed border) or, beyond NOAA's own ~7-10 day horizon, this station's historical average for that calendar date (dotted border, "Historical avg") - not a real forecast, lower confidence still. Greyed-out days have no data - outside the fetched window, or a gap in it. Tap a day for the full reasoning behind each factor.
Historical avg - beyond NOAA's real forecast
Growth Stage
Slow GrowthHistorically, daytime highs around this date average 55°F - outside the peak ~60-75°F window. If this is driven by heat rather than cool weather, treat as optimistic: heat-driven dormancy can't be projected forward without a forecast rainfall amount.
Mowing
Good timeHistorically slow growth around this date - expect to mow every 7-10 days at this rate if the pattern holds. This is a multi-year average, not a forecast - actual conditions this far out may differ meaningfully; re-check closer to the date.
Fertilizing

Pre-Emergent
Hold offCrabgrass pre-emergent is a spring job - nothing to do until next year. NDSU Extension: apply when 4-inch soil temps reach about 50°F, usually mid-April to mid-May.

The Fargo-Moorhead lawn year at a glance
The dashboard above tells you what to do today. Here's the whole year, from NDSU Extension.
- Mid-April to mid-May - crabgrass pre-emergent
- Apply when soil at a 4-inch depth reaches about 50°F - roughly a week before it averages 55°F and crabgrass starts sprouting. NDSU points to NDAWN's turf soil temperatures, the same station data this dashboard uses. (NDSU)
- Around Memorial Day - optional spring feeding
- If you fertilize in spring, do it near Memorial Day, not earlier. Earlier feeding pushes blade growth at the expense of roots and has little long-term benefit. (NDSU)
- Summer - skip the fertilizer
- Fertilizing in summer has very little benefit unless your lawn is regularly irrigated. (NDSU)
- Around Labor Day - the feeding that matters most
- Fertilize around Labor Day, ideally before September 15, with a fertilizer that's about half slow-release nitrogen. September is when roots grow, so this is the one feeding a year to prioritize. (NDSU)
- October on - stop fertilizing
- NDSU doesn't recommend fertilizing past the end of September. October feeding can keep the lawn growing when it should be hardening off, which risks winterkill. (NDSU)
