Step 3: Removing the Grass Lawn

Transitioning from a traditional grass lawn to a xeric garden is a crucial step in the process of xeriscaping. Removing the grass effectively ensures that your new water-efficient landscape can thrive without the competition from grassy areas. There are several methods you can use to remove the grass, including physical removal, solarization, and sheet mulching. Additionally, taking advantage of a turf replacement program can make this step easier and more efficient.

Physical removal involves manually digging up the grass and its root system using a shovel or other gardening tools. This method is labor-intensive but allows for precise clearing of the grass. Solarization, on the other hand, utilizes the sun’s heat to kill the grass. To solarize your lawn, cover it with a clear plastic sheet for several weeks to create a greenhouse effect that steams the grass and eliminates it.

Sheet mulching is another effective approach to grass removal. This method involves layering materials over the grass to smother it and create a nutrient-rich foundation for your xeric garden. Start by mowing your lawn as short as possible and then covering it with cardboard or several layers of newspaper. Add a layer of compost or organic matter, followed by a layer of mulch. This process gradually breaks down the grass while nourishing the soil beneath.

Utilizing a turf replacement program can provide additional support during the process of grass lawn removal. These programs often offer resources, such as guidance on preferred removal methods, access to equipment rentals, and even financial incentives. Check with your local government or water conservation organizations to see if there are any turf replacement programs available in your area.

Step 4: Planting Xeric Plants and Adding Mulch

With the grass lawn successfully removed, it’s time to move on to the next step: planting your chosen xeric plants and adding mulch. Planting xeric plants in your xeriscape garden is crucial for creating a low-maintenance, water-efficient landscape that thrives in Colorado’s unique climate. Here’s what you need to know.

Planting Xeric Plants

When planting xeric plants, it’s important to follow proper techniques to ensure their success. Start by digging holes that are wider than the root ball of the plant but only as deep as the root ball itself. Gently remove the plant from its container, being careful not to damage the roots, and place it in the hole. Backfill the hole with soil, firming it gently around the plant.

Spacing is also key when planting xeric plants. Be sure to follow the spacing guidelines provided for each plant, as overcrowding can lead to competition for resources and hinder their growth. Providing organic fertilizer at the time of planting can also help promote healthy growth and establishment.

Adding Mulch

Once your xeric plants are in place, it’s time to add mulch. Mulch serves several important purposes in a xeriscape garden, including conserving moisture, regulating soil temperature, and suppressing weed growth.

There are a variety of mulch options to choose from, including gravel, rock mulches, and organic mulches like bark chips. Consider using organic mulches as they break down over time, adding beneficial organic matter to the soil. Apply a layer of mulch around the base of your plants, taking care not to pile it up against the plant stems or tree trunks. This will help retain moisture and prevent weed seeds from germinating.

Remember to replenish mulch periodically, as it can break down over time. Regularly check the depth of the mulch and add more as necessary to maintain a layer that is approximately 2-3 inches thick.
