Bog Garden Top-Dressing: Pea Gravel Helps, But Summer Watering Still Required

Top-Dressing Value

Pea gravel is the best top-dressing — suppresses weeds, reduces evaporation, looks natural. Dry sphagnum works but blows away.

You must water in summer. Rain alone won't suffice during heat waves, even with a liner and forked drainage. Bog gardens dry from the top down.

Liner with forked holes = good drainage. Plants not yet planted = perfect time to add gravel top-dressing after planting.
