Topdressing
Short definition
Topdressing is spreading fertiliser, compost or other material evenly over the soil surface.
A thin layer of compost on a lawn or around shrubs feeds the soil slowly as water carries nutrients down. In pots, a little fresh mix on top replaces what has settled or washed out.
Why it matters
Keep material away from stems and trunks, and water in afterwards.
