Lawn timing geography of Arkansas
Across the 112 Arkansas locations with complete 1991–2020 frost
normals, the average last spring frost — the anchor for pre-emergent and spring
work — ranges from Mar 10 (Arkansas Post) to Apr 15
(Fayetteville Drake Field), a spread of about 5 weeks driven by elevation, latitude, and terrain.
The same job can be weeks apart at opposite ends of the state, which is why a
state-level date is only a starting point — pick the location nearest your yard and
plan from its calendar.
The Arkansas lawn year in one paragraph
Arkansas lawns run on two opposite calendars. Tall fescue and bluegrass lawns treat early fall as the main event — aerate, overseed, feed — with spring for pre-emergent and light feeding. Bermuda and Zoysia lawns flip it: establish and feed from late spring through summer, stop nitrogen 6–8 weeks before frost, and accept winter brown as normal. Identify your grass first; every date on this page depends on it. Details by task: when to overseed in Arkansas, when to aerate in Arkansas, when to apply crabgrass pre-emergent in Arkansas, and more above.
