Contained planters reduce runoff from small areas while beautifying the landscape.
When Is this Practice Used?
Where you have impervious surfaces (pavement, patio, paved walkways) that can not be removed, but you would like to add landscaping
Reduces stormwater runoff
rainwater is stored in the planting container rather than immediately becoming stormwater runoff from the impervious surface below it
can reduce annual runoff by 40% to 60% from areas on which they are placed
Allows for the creation of landscaped spaces in heavily paved areas or poor soil conditions
Suitable for rental properties
Can be more accessible for those with limited mobility
How to implement
Select a durable container that will be suitable for being outside year round
Ensure the container has a hole in the bottom
Fill the container with soil (consider native soil or amended native soil rather than potting soil
Add water to the soil as you fill the container to keep the soil moist
Add your native plants
Containers will require additional watering during the summer months
Container may need protecting from freezing temperatures
