Just as your yard has four distinct seasons of growth and rest, it has four distinct seasons of landscape maintenance. What you have to do depends on the time of year and the type of tree or plant. Here are checklists for seasonal lawn care; trees, shrubs, and groundcovers; flower and kitchen gardens; and hardscape elements to make the work easy to tackle no matter the time of year.

Spring Landscape Maintenance

Spring Lawn Care

  • Use a spring fertilizer for lawns once snow has melted.
  • Repair dead patches.
  • If crabgrass is problematic, treat with a preemergent herbicide around the time forsythia blooms in your area.
  • Revive weak lawns by dethatching and aerating.
Spring Trees, Shrubs, and Groundcover Maintenance
  • Remove winter trunk protection and old mulch, and remulch at the base of trees and shrubs.
  • Prune and clean up dead, broken, or diseased branches.
  • Prune summer-flowering shrubs.
  • Rake, fertilize, and groom groundcovers.
  • After dry winters, thoroughly water new plants.

  • Prune vines growing over arbors and trellises.
  • Cut back spring bulb foliage as it yellows.

Spring Hardscape Maintenance

Summer Landscape Maintenance

Summer Lawn Care

  • Mow regularly and as needed. Leave the clippings on the lawn, and remove only one-third of the grass height at one time.
  • As summer progresses, raise the mowing height; taller grass holds up to heat and drought better.
  • Alternate your mowing pattern to avoid creating strips or ruts.
  • Water in the morning as needed; soak until the lawn receives about 1 inch a week.

Summer Trees, Shrubs, and Groundcover Maintenance

  • Weed as needed around trees; add mulch, keeping material 1-2 inches away from tree trunks.
  • Regularly check for insect or disease damage.
  • Water new shrubs and trees once a week, moistening soil to a depth of 1 foot.
  • Trim hedges after the first new growth flush.
  • Deadhead faded flowers.
  • Prune spring-blooming shrubs, such as lilacs, after flowers fade.

Summer Garden Maintenance

  • Mulch beds as needed.
  • Cut flowers and herbs in the morning; harvest vegetables as needed and fruits when ripe.
  • Prune fruit-bearing shrubs and replant strawberries after fruiting.
  • Maintain vigilance for insects and diseases.
  • Water containers when dry.
  • Fertilize flowers and vegetables monthly.
  • Deadhead flowers for fall. 
  • Train vines by tying or light pruning.

Summer Hardscape Maintenance

  • Clean tools after each use.
  • Clean and repair cold frames.
  • Weed between pavers in pathways; repair cracks as needed.
  • Paint or stain building exteriors as needed.

Fall Landscape Maintenance

Fall Lawn Care

  • Autumn lawn care is simple: Overseed new lawn or spots that need refreshing. Begin mid-October in mild-winter climates; in cold-winter climates, overseed in mid-September.
  • Use a fall grass fertilizer on your lawn.
  • Rake leaves as needed.

Fall Trees, Shrubs, and Groundcover Maintenance

  • Mulch and regularly water newly planted conifers.
  • Plant new additions such as oak, holly, and beautyberry.
  • Clean up rotten, fallen crops and leaves from fruit trees.
  • Rake and compost leaves.
  • Cut back rose canes to within a foot of the ground, and cover them with soil (cold climates). Wrap the canes of tender roses in burlap, lay the wrapped canes on the ground, and cover them with soil or mulch.

Fall Garden Maintenance

Fall Hardscape Maintenance

  • Clean tools after use.
  • Run gas engine mowers until empty, or add fuel stabilizer.
  • Drain permanent water systems, pools, and ponds (in cool climates).
  • Store hoses, outdoor furniture, and tools.

Winter Landscape Maintenance

Winter Lawn Care

  • If your lawn is green in winter, lightly dose with nitrogen fertilizer in late winter.
  • For optimal winter lawn care, avoid walking on it if it is dormant or frozen, and use alternatives to salt (sand or kitty litter) as appropriate.

Winter Trees, Shrubs, and Groundcover Maintenance

  • If rain and snow are lacking, water newly planted evergreens.
  • Plant bare-root roses as soon as you can.
  • Prune fruit trees in late winter; spray with dormant oil.
  • Wrap trees with tree guards to protect from rodent damage.
  • Wrap tender foundation shrubs in burlap.

Winter Garden Maintenance

  • Review wintering bulbs, discarding those that are soft or rotten.
  • Order seeds for spring.
  • Fertilize flowers in mild-winter regions with a fast-acting fertilizer.
