This is a document about rainwater garden maintenance
This manual provides step-by-step maintenance procedures for rain gardens and vegetative filter strips, focusing on sediment removal, vegetation health, and water infiltration. It includes troubleshooting for erosion, clogged inlets, weed control, and mulch management. Maintenance is recommended twice annually, with more frequent checks during the growing season.
The guide also covers vegetation trimming guidelines, mulch types, and integrated pest management practices, including hand-weeding and limited herbicide use. It references the Environmental Criteria Manual (ECM) for vegetation selection and plant stress management.
Inspections should be performed at least twice annually once vegetation is established, with more frequent checks during the growing season (March through November).
Mulch should be applied to a consistent 3-inch depth.
All woody weeds must be physically removed annually.
Tall herbaceous plants should be cut no lower than 18 inches from the ground.
