I power wash my sidewalks and patio each spring before planting season, really as soon as the snow clears. You would be surprised how much dirt accumulates over the winter and the sidewalks look like new when clean. Why before planting season? Because I plant annuals up and down both sides of my side walk, so by doing it before planting it eliminates any over watering or damage from the spray to the annuals. It's just another spring cleaning task out of the way before the gardens come alive.
