- Create overlapping sections and pockets between rocks to add depth.
Incorporating Plants
Now that your rocks are in place, it’s time to add the plants. Here’s how to do it effectively:
- Choose Plant Locations: Opt for plants that thrive between rock crevices or planted directly into the soil, aligning with your earlier sketch.
- Planting: Dig holes slightly larger than the root ball of each plant. Place your plants and fill around them with soil, firming it gently to eliminate air pockets.
- Layering Plants: Use taller plants towards the back and smaller ones at the front to create a layered look.
Adding Accents and Details
Once the primary elements are in place, add some finishing touches to enhance your rock garden.
- Ground Cover: Introduce a ground cover plant between rocks to create a carpet-like effect.
- Mulch or Gravel: Spread a layer of mulch or decorative gravel for added texture and weed prevention.
- Garden Decor: Consider incorporating garden statues, lanterns, or artistic stones for personal flair.
Maintaining Your Rock Garden
With your rock garden complete, regular maintenance is crucial for keeping its charm intact.
Watering and Fertilization
- Watering: Newly planted areas will require more water until established. Once established, most rock garden plants are drought-tolerant.
- Fertilization: Apply a slow-release fertilizer once a year in early spring to promote healthy growth.
Weeding and Pruning
- Periodically check for weeds, pulling them by hand to avoid disturbing the rock formations.
- Prune plants as needed to maintain their shape and promote longevity.
Seasonal Cleanup
- Remove dead leaves and debris, particularly before winter, to keep the area tidy.
- Check for shifting rocks or erosion and make adjustments as necessary.
