Rain garden maintenance:
Water: Water the rain garden regularly (once per week for the first 2-3 months or so). Deep watering once per week is preferable to daily, shallow watering. Once the plants’ root systems are established, it will only need watering during heat waves or long periods without rain.
Weed: Weed and prune as you would any garden.
Do not plant edible food in a rain garden: Stormwater running into the garden may carry dirt and debris not suitable for edible plants. In addition, all urban soils should be tested for lead and other potential contaminants before being used for growing edibles. For more information, read Healthy Gardening in Urban Soils.
- After heavy thunderstorms or downpours, check for signs of erosion or gullies. Add more plants, river rocks or mulch to address these concerns.
- Do not be afraid to move plants around if you think they would do better in drier or wetter parts of the garden.
