Drought Tolerant Landscaping

Post
A low water use yard has many possibilities! There are different types of drought tolerant landscapes that contain a lot of color and vibrancy. The climate in Redlands is described as a Mediterranean environment, which means hot and dry summers with mild, wet winters. There are many beautiful plants that thrive in this type of environment. Unfortunately, our traditional turf grass lawns are not native to this area and require a lot of water. Consider taking out some of your grass that is not frequently used, such as your front yard, and replacing it with appealing drought tolerant flowers, trees, or shrubs.

The City of Redlands’ code requires that at least 80% of the visible front yard area be plant material. This can be plants, trees, shrubs, grass, or even synthetic turf. No more than 20% of the front yard area can be hardscape material such as decomposed granite, rock, or mulch. Click here for examples of landscapes that follow the 80/20 rule and those that do not follow the 80/20 rule..

Here are five steps to maintain a lush efficient garden that requires less water and pruning.

1. Hydrozone: group plants according to their water needs. Hydrozone your yard and garden so that low water-use and moderate water-use plants are grouped together. Also, use elevated planting beds so that plants are watered more efficiently, thereby reducing overall water usage.

2. Selecting Plants: use drought-tolerant or native plants to create a low water-use, low maintenance landscape.

3. Irrigation: install micro-sprinklers, drip emitters, and weather based irrigation timers so you only give plants the amount of water they actually need.

4. Improve Your Soil: mix compost into your soil to improve its moisture retaining capability and fertility.

5. Use Mulch: place mulch around your plants, along walkways, and on top of other bare areas to reduce water use and prevent weeds.

Landscapes with a Purpose: Rain Gardens

Rain Gardens are a shallow, depressed garden that captures stormwater from from roof tops, gutters, and streets and allows it to infiltrate into the ground within 24-48 hours. The soil and sand in rain gardens are able to filter out many pollutants that come off of roof tops and streets. Also, rain gardens that are planted with native California plants require 75% less irrigation than grass lawns and can add a unique and beautiful element as an alternative to traditional grass lawns. 

Bioretention Cells are very similar to rain gardens except bioretention cells typically have a perforated pipe and gravel underneath for drainage whereas rain gardens rely on native soil and sand components for drainage.

Why install a rain garden? Not only do rain gardens collect water and divert it to the groundwater and help recharge the basin but they can lessen storm water runoff which flows down pavement and roadways collecting pollutants such as copper, lead, zinc, phosphorus, nitrogen, oil, grease, soil, detergents, and organic matter which then flow into storm drainage systems and into our waterways. Diverting rainwater into rain gardens not only reduces the amount of pollutants in our waterways and recharges the groundwater but can lessen the maintenance of existing city infrastructure.
