By LandMaXx Corp. · Last updated September 29, 2026. Timing shifts with weather, soil moisture, grass type and the site. This calendar is educational; it does not describe an automatic treatment program or promise that every listed service is included in a LandMaXx plan.
January and February — protect dormant turf
Keep unnecessary traffic and stored materials off frozen or saturated lawn areas. Review last season’s thin spots and drainage concerns while planning spring work. Record where snow is stored and discuss protection for lawn edges before the next event. Equipment maintenance and a clear service scope can be arranged before active growth returns.
March — inspect before working
Walk the property when conditions allow and note debris, plow-edge damage and persistent wet areas. Schedule cleanup around ground conditions rather than the first warm afternoon. Collect a soil sample when workable and identify the cause of recurring bare areas before deciding to reseed. Avoid heavy equipment on soft ground.
April — start according to growth
Begin mowing when grass is actively growing and soil supports the equipment. Use a sharp blade and choose height for the lawn’s grass type; the Connecticut calendar linked below generally uses about three inches during the growing season. Clean up concentrated debris without stripping healthy turf. Review soil-test recommendations before buying amendments.
May — adjust frequency to the lawn
Observe how quickly the lawn grows and adjust visits instead of forcing a fixed cutting interval through every condition. Keep grass clippings from forming thick mats. Check bed edges and access routes as part of maintenance planning. Any fertilizer or amendment decision should follow the soil test, product directions and applicable requirements.
June — prepare for heat
Reassess mowing frequency as growth changes. Note areas that receive different amounts of sun or show recurring compaction. Keep a record of where turf struggles so late-summer renovation addresses the cause. Avoid assuming that every brown area needs more fertilizer or the same watering response.
July — respond to stress
Reduce unnecessary traffic over stressed areas and avoid cutting simply because a calendar visit is due. Distinguish dormancy, drainage problems and persistent bare soil before choosing corrective work. Plan an irrigation discussion around the actual site, any restrictions and whether the lawn is established or newly seeded.
August — plan targeted renovation
UConn identifies approximately August 15 through September 15 as a useful window for cool-season lawn renovation. Decide whether the lawn needs overseeding, targeted repair or a different planting approach. Core aeration is generally intended for compacted soil. UConn’s late-summer lawn guidance explains the timing.
September — establish the repair
Use the soil test and site conditions to guide preparation. Keep newly seeded areas consistently managed through establishment and protect them from routine traffic. Shade or poor soil can undermine a reseeding project unless addressed. See UConn’s lawn renovation and repair guide before selecting a repair method.
October — manage leaves and continued growth
Continue mowing while growth requires it. Keep heavy leaf accumulation from covering the turf, coordinating cleanup with the property’s trees and the pace of leaf drop. Review any remaining renovation areas and separate unfinished repair from ordinary maintenance. Confirm how collected material will be handled in the service scope.
November — finish seasonal cleanup
Plan final visits around actual growth and leaf conditions. Clear concentrated debris, note drainage concerns and mark sensitive edges where winter operations may occur. Discuss the final mowing height for the grass and conditions instead of applying a universal short-cut rule. Fertilization is not an automatic end-of-season task.
December — review the next season
Keep a short list of the areas that need a different approach next year. Save the soil-test report, approved work scope and establishment instructions. A maintenance plan works best when mowing, cleanup and any specialist treatments have clearly assigned responsibilities.

Common questions
Should I aerate every lawn every year?
Not automatically. Identify compaction and site conditions first; UConn describes core aeration as generally needed where soils are compacted.
Does this calendar include a fertilizer package?
No. It is a planning guide. Confirm any treatment scope separately and use soil-test guidance and product directions.
