March Lawn & Garden: Step-by-Step Schedule

March Lawn & Garden: Step-by-Step Schedule 

March is the month to wake your yard up: clear winter debris, relieve compacted soil, and get ahead of weeds and moss so spring growth is strong. Below is a clear, week-by-week and day-by-day plan you can follow through March, plus a printable checklist at the end.

March Schedule — Week by week (easy to follow)

Week 1 (March 1–7) — Clean & Prep

• Day 1–2: Winter cleanup
  
• Rake leaves, pick up twigs and debris from lawn and beds. Remove any dead annuals.
• Pull out or cut back winter-damaged perennials and grasses left for winter interest.
• Day 3: Tool & mower service
  
• Sharpen mower blades, clean the deck, replace oil/air filter if needed, check spark plug.
• Clean and oil hand tools (pruners, shovels).
• Day 4–7: Inspect & plan
  
• Walk the property: mark bare/thin lawn spots, compacted areas, moss patches, and beds that need mulch or soil amendment.
• Check irrigation systems/startup and timers (if you have one) — don’t run frequently yet; only if dry.

Week 2 (March 8–14) — Weed prevention & early care

• Apply pre-emergent herbicide (early March — ideally when soil temps reach ~50°F for several days; adjust for local climate):
  
• Use a product labeled for your grass type and follow label rates. This prevents crabgrass/annual weeds.
• 
  
• Moss control / iron application
  
• Treat moss patches with an iron-based product to darken and suppress moss; follow label directions.
• 
  
• Light watering
  
• If March is dry, water deeply once or twice during the week to encourage root growth (avoid shallow, frequent watering).

Week 3 (March 15–21) — Soil care & lawn repair

• Core-aerate the lawn
  
• Aerate compacted areas — best when soil is moist but not muddy. Rent or hire a core aerator for best results.
• 
  
• Overseed thin/bare patches (if cool-season turf)
  
• After aeration, overseed bare spots and lightly rake seed into soil; keep seedbed moist until established.
• 
  
• Fertilizer / iron (optional)
  
• Apply a balanced spring fertilizer or an iron supplement if lawn looks pale. Match fertilizer type to your grass (cool-season vs warm-season).

Week 4 (March 22–31) — Prune, plant, mulch

• Pruning
  
• Prune summer-flowering shrubs and trees now (before new growth starts). Remove dead wood and shape lightly.
• Cut back ornamental grasses and divide early perennials (hostas, daylilies) if desired.
• Plant cool-season crops & cold-hardy ornamentals
  
• Plant lettuce, spinach, radishes, peas and other cool-season vegetables.
• Transplant hardy perennials and add early spring color (pansies, snapdragons where appropriate).
• Mulch & soil amendments
  
• Add 1–2” of organic mulch to beds (keep mulch off crowns/stems). Top-dress garden beds with compost if needed.

Quick mowing & maintenance timeline to follow during March

• Before first mow: Only mow when grass is actively growing and soil is dry enough to avoid compaction.
• First mow: Set mower high (leave grass taller than usual) and only remove the top 1/3 of the blade height.
• Weekly checks: Walk the yard once a week for pest/mold issues, frost risk, or new winter damage. Keep frost blankets handy if late cold snaps threaten 

March Lawn & Garden Checklist

• [] Rake and remove winter debris (leaves, twigs)
• [] Cut back dead perennials & ornamental grasses
• [] Sharpen mower blades; service mower & tools
• [] Inspect & turn on irrigation; test timers
• [] Apply pre-emergent herbicide (early March)
• [] Apply iron to moss patches (if needed)
• [] Core-aerate lawn (mid-March)
• [] Overseed thin/bare spots (after aeration)
• [] Apply balanced spring fertilizer or iron (as needed)
• [] Prune summer-flowering shrubs & remove dead wood
• [] Plant cool-season vegetables & divide perennials
• [] Add mulch / top-dress beds with compost
• [] First mow when grass is actively growing; set blades high

Notes & tips (short)

• Adjust for your climate and grass type. Cool-season lawns (fescue, bluegrass, rye) follow slightly different timing than warm-season lawns (Bermuda, zoysia). If you’re unsure which you have, check local extension resources or tell me your city and I’ll tailor the schedule.
• Follow product labels. Always follow label instructions for herbicides, fertilizers, and moss treatments.
• Safety & timing. Avoid heavy work on wet soil to prevent compaction; aerate when soil is moist.
