Spring in Maine doesn’t ease in gently. You get a couple of warm days, then a frost warning, then mud season, then suddenly it’s May, and the ground is finally cooperating. 

Knowing when to do what – and not jumping the gun – is the difference between a yard that thrives and one that spends all summer recovering. Here’s a month-by-month breakdown of what to tackle and when.

April: Patience First, Then Prep

April is a trap. The urge to get outside and start digging is real, but Maine soil needs time to dry out after the snow melts. Walking on or working wet soil compacts it, causing more harm than a few extra weeks of waiting. Before anything else, do a simple squeeze test – grab a handful of soil and squeeze. If it crumbles when you open your hand, you’re good. If it holds a shape like clay, give it another week.

What to focus on in April:

  • Walk your property and take stock of winter damage. Note areas where grass didn’t come back, spots where ice piled up, and any heaving in patios, walkways, or retaining walls.
  • Clear debris, dead branches, and matted leaves from lawn areas. Wet leaves left sitting block sunlight and invite disease.
  • Check irrigation systems for any freeze damage before turning them back on.
  • Contact your landscape contractor to schedule spring services – good companies book up fast once May hits.

Hold off on fertilizing, seeding, and heavy pruning until the ground firms up and nighttime temperatures are consistently above freezing.

May: The Real Work Begins

May is when Southern Maine comes to life, and your to-do list gets serious. Soil temperatures are warming, grass is actively growing, and conditions are right for most spring lawn and landscape work. This is the month to be proactive – get ahead of weeds before they set seed, and get seed or sod down while cool-season conditions still favor root development.

Priority tasks for May:

  • Aerate compacted areas. If your lawn sees heavy foot traffic or has had standing water this spring, core aeration now will help roots breathe and improve drainage heading into summer.
  • Overseed thin or bare patches. May gives cool-season grasses like Kentucky bluegrass and tall fescue the best chance to establish before summer heat arrives.
  • Apply a slow-release starter fertilizer after seeding, or a balanced lawn fertilizer for established turf. Avoid anything high in nitrogen too early – it pushes top growth at the expense of roots.
  • Edge beds, apply 2 – 3 inches of fresh mulch, and cut back any ornamental grasses or perennials that weren’t cut in fall.
  • Prune spring-flowering shrubs like forsythia and lilac immediately after they bloom – pruning before flowering means losing the blooms.

For commercial properties, May is also the time to assess parking lot plantings, address any winter-salt damage along borders, and lock in a landscape maintenance plan for the season.

June: Establish, Maintain, and Watch

By June, the heavy lifting is done, or should be. Grass seeded in May is filling in, mulch is down, and the focus shifts to maintaining what you’ve built and keeping an eye out for problems before they get ahead of you.

June checklist:

  • Set your mowing height to 3 – 3.5 inches. Cutting too short stresses cool-season grasses as summer heat approaches, giving weeds a foothold.
  • Water new seed or sod consistently – shallow, frequent watering for the first few weeks, then transition to deeper, less frequent cycles to encourage deep root growth.
  • Scout for grubs and surface insects. June is when damage starts showing up. Treat early if you spot irregular brown patches that pull up easily from the soil.
  • Check hardscape elements installed in spring. Settle any pavers or flagstones that shifted, and make sure drainage around new features is working as intended.
  • For new construction properties or major renovations, June is the last realistic window for hydroseeding before summer heat makes establishment difficult.

Maine’s spring window is short, which means the order of operations actually matters. Rush it in April, and you’ll be fighting compaction and patchy growth all summer. Follow the calendar, and by late June, you’re mowing a full, healthy lawn and enjoying your outdoor space – not chasing problems.If your property needs professional spring cleanup, lawn renovation, or a landscape refresh, the Greencare team is scheduling now.
