Seasonal Checklist

What your Willamette Valley yard and pond actually need, month by month. Print it, stick it on the fridge.

January

Yard

  • Prune dormant fruit trees on a dry day
  • Apply dormant oil spray to fruit trees and roses
  • Stay off soggy or frozen lawn
  • Check downspouts and bed drainage during heavy rain

Pond

  • Keep de-icer running so ice never seals over
  • Never break ice — the shock harms fish
  • Stop feeding fish; water is below 50°F

February

Yard

  • Prune roses around Presidents Day
  • Cut back ornamental grasses before new growth
  • Apply moss control to the lawn
  • Finish dormant pruning before buds break

Pond

  • Inspect pump, plumbing, and liner for winter damage
  • Top off water lost to wind and evaporation

March

Yard

  • First mow once the lawn dries out
  • Edge beds and spread fresh mulch
  • Apply spring lawn fertilizer with moss control
  • Pull weeds now, before they set seed

Pond

  • Do the spring cleanout: net debris, rinse filters
  • Restart pump and waterfall
  • Add beneficial bacteria once water hits 50°F

April

Yard

  • Aerate and overseed — prime spring window
  • Fertilize the lawn after overseeding
  • Plant trees, shrubs, and perennials
  • Mow weekly; keep blades sharp

Pond

  • Start feeding fish lightly above 50°F
  • Divide and repot marginal plants
  • Fertilize water lilies

May

Yard

  • Start up irrigation; check every zone and head
  • Schedule backflow test — it's required annually
  • Finish any overseeding early in the month
  • Spot-treat lawn weeds while they're young

Pond

  • Add floating plants for summer shade
  • Pull string algae by hand as it appears
  • Move to regular fish feeding

June

Yard

  • Raise mower height to 2.5–3" for summer
  • Dial in irrigation as the rain shuts off
  • Deadhead spring bloomers
  • Prune spring-flowering shrubs after bloom

Pond

  • Aim for 60% surface coverage with lilies and floaters
  • Top off weekly with dechlorinated water
  • Empty skimmer basket often

July

Yard

  • Water deeply, early morning — about 1" per week
  • Mow high; never cut more than a third
  • Watch new plantings for drought stress
  • Soak trees and shrubs every couple weeks

Pond

  • Run aeration overnight during heat waves
  • Feed fish in the cool of the morning
  • Top off — summer evaporation runs fast

August

Yard

  • Keep deep watering through the dry stretch
  • Skip fertilizing stressed lawns
  • Plan fall planting and lawn projects now
  • Check drip emitters and adjust run times

Pond

  • Rinse filter pads in pond water, not tap
  • Trim yellowing lily leaves at the base
  • Watch fish at dawn — gasping means low oxygen

September

Yard

  • Aerate and overseed — the best window of the year
  • Apply fall lawn fertilizer
  • Cut irrigation back as the rains return
  • Plant trees and shrubs; fall roots beat spring

Pond

  • Net the pond before leaves start dropping
  • Switch to cold-water fish food below 60°F
  • Cut back marginal plants as they fade

October

Yard

  • Winterize irrigation: blow out lines, insulate backflow
  • Keep leaves raked off the lawn
  • Plant spring bulbs and garlic
  • Apply lime if a soil test calls for it

Pond

  • Keep the net tight through peak leaf drop
  • Stop feeding fish once water drops below 50°F
  • Remove tropical plants before frost

November

Yard

  • Final mow, slightly shorter than summer height
  • Clean gutters and check drainage before storms
  • Drain hoses and cover spigots
  • Mulch tender perennials before a hard frost

Pond

  • Pull the net once the leaves are down
  • Install the de-icer before the first hard freeze
  • Shut down or winterize the waterfall pump

December

Yard

  • Stay off frozen or waterlogged turf
  • Prune dormant shade trees for structure
  • Sharpen mower blades and service tools
  • Sketch next year's landscape projects

Pond

  • Confirm the de-icer keeps a hole open in ice
  • Leave the fish alone — no feeding until spring
  • Knock heavy snow off netting or covers
