Raingarden Care and Maintenance
Fig 1; Curbside Raingarden used to filter local runoff from the street and yard. Note the stone edger near curb inlet being used to for erosion control.
Once established raingarden maintenance is fairly low only needing some limited upkeep each year. To be sure your rain garden is functioning at its best as stormwater tool, stormwater needs to be able to flow into it. Keep an eye on the inlet at the yard or street for buildup. If leaves, grass clippings etc. are accumulating take the time to remove them. If the ground is starting to erode in the inlet area, installing some rock rip rap or a stepping stone or two may be needed to reinforce the area.
As well as being functional, raingardens should be aesthetically pleasing. Early on you will need to do some weeding until the plants get established and fill in the raingarden basin. How much will depend on whether you seeded, planted from plugs or pots, or in combination. It will also depend on how naturalized or manicured you want the raingarden to look. You may need to move, remove, or add plants to get the appeal that you’re looking for. If some plants are too tall, you can move them to the back, or remove them altogether. Some species that grow too aggressively like coneflower may need to be thinned-out.
Spring Checklist
- Add new plants, if needed
- Cut and remove dead stalks and seed heads remaining from the previous season
- Divide and move plants if they are crowding the garden
- Prune shrubs, if necessary, in March or early April
- Remove silt and debris from inlet
- Replenish mulch to 3 inches thick

Where All That Water Is Actually Coming From Your backyard stays wet. You've noticed the soggy spots, the mud, maybe some frost heave damage to your patio or fence. You're thinking about French drains. But before you start digging trenches, look up. A huge amount of water hitting your yard isn't coming from rain falling on the lawn. It's coming from your roof. A moderate rainfall on a typical Plymouth home puts hundreds of gallons through your gutter system. Every bit of that water exits through your downspouts. Where it goes from there determines whether you have a drainage problem or not. Then there's your sump pump. Every time it kicks on, it's pushing water out of your basement and into your yard. On a wet property, that pump might run dozens of times a day. All that water has to go somewhere. If your downspouts dump water next to your foundation and your sump pump discharges into a side yard that drains toward your backyard, you're adding water to an already saturated situation. French drains alone might not be enough. You need to manage the sources. The Problem With Surface Discharge Most downspouts in Plymouth end with a splash block or a short extension that dumps water a few feet from the foundation. That's technically moving water away from the house, but not far enough.
