Step 6: Add Edging (Optional)
If you choose, now is the time to install edging materials around the base. This addition not only provides a neat appearance but can also help maintain the shape of the berm over time.
Step 7: Planting
Once your berm is shaped, it’s time to plant! Start with the tallest plants at the back or center and then work to shorter ones toward the edges—all aiming for a harmonious design. Consider spacing plants adequately to encourage proper growth.
Watering:
After planting, give everything a thorough watering to help establish the roots.
Maintenance of Your Garden Berm
Creating your garden berm is just the beginning; maintenance is equally crucial to ensure its longevity.
Watering
Regular watering is essential, especially during the first year as plants establish themselves. Ensure the area remains moist but not soggy.
Weeding
Keep an eye out for weeds that may try to invade your berm. Regular weeding will help maintain the health of your plants.
Mulching
Adding a layer of mulch will help retain moisture, suppress weed growth, and add nutrients to the soil as it breaks down.
Annual Evaluation
Every year, reassess the condition and arrangement of your berm. Adjust plant selections, remove dead plants, and add new ones as necessary to keep it vibrant.
