Stones, often overlooked features in our gardens and landscapes, play a crucial role in creating diverse and beneficial ecosystems. What lies beneath them is just as important as the stones themselves. Understanding what to put under stones allows you to transform these simple objects into thriving microhabitats, benefiting your garden’s health, supporting local wildlife, and adding an element of natural beauty. This comprehensive guide explores the best practices for preparing the ground under stones, ensuring a flourishing environment for plants, insects, and more.
Preparing the Foundation: Soil and Drainage
The success of any habitat under stones hinges on proper soil preparation. A well-draining and nutrient-rich foundation is essential for plants and other organisms to thrive. Poor drainage leads to waterlogging, which can suffocate roots and create an environment conducive to fungal diseases. Before placing any stones, assess your existing soil and amend it accordingly.
Assessing Your Soil Type
Identifying your soil type is the first step. Common soil types include sandy, clay, silty, and loamy. Sandy soil drains quickly but doesn’t retain nutrients well, while clay soil retains water but can become compacted. Silty soil is smooth and fertile, but can be prone to erosion. Loamy soil, a mixture of sand, silt, and clay, is generally considered ideal. A simple soil test kit from your local garden center can provide valuable information about your soil’s pH and nutrient levels.
Improving Drainage
If your soil is predominantly clay, improving drainage is crucial. Incorporating organic matter such as compost, well-rotted manure, or leaf mold can significantly improve soil structure and drainage. Adding coarse sand or gravel can also help break up compacted clay. Another effective technique is to create a raised bed or mound where you intend to place the stones. This elevates the planting area, allowing excess water to drain away more easily.
Enriching the Soil
Regardless of your soil type, enriching it with organic matter is always beneficial. Compost is a fantastic all-around amendment that improves soil structure, drainage, and nutrient content. Well-rotted manure provides a slow-release source of nutrients. Leaf mold, made from decomposed leaves, is excellent for improving soil structure and water retention. Incorporate these materials thoroughly into the soil before placing the stones. Consider using a balanced organic fertilizer to provide an extra boost of nutrients.
Choosing the Right Materials for Under Stones
Once the soil is prepared, the next step is to consider the materials you will use beneath the stones. These materials serve several purposes, including weed suppression, moisture retention, and providing a suitable substrate for plant roots.
Weed Barriers: Controlling Unwanted Growth
Weeds are a common challenge in gardens and landscapes. Using a weed barrier under stones can help prevent unwanted growth and reduce the need for manual weeding. Landscape fabric is a popular choice, allowing water and air to pass through while blocking sunlight, which weeds need to germinate. Ensure the fabric is properly secured to prevent it from shifting or tearing.
Another option is to use cardboard or newspaper as a weed barrier. These materials decompose over time, adding organic matter to the soil. However, they may not be as durable as landscape fabric and may require replacement more frequently. Avoid using plastic sheeting as a weed barrier, as it can prevent water from reaching the soil and create anaerobic conditions.
Moisture Retention: Keeping Plants Hydrated
Maintaining adequate moisture levels is essential for plant health, especially in hot and dry climates. Incorporating moisture-retentive materials under stones can help reduce the need for frequent watering. Peat moss is a commonly used amendment that holds a significant amount of water. However, its use is controversial due to its environmental impact.
Coco coir, made from coconut husks, is a sustainable alternative to peat moss. It has excellent water-retention properties and improves soil aeration. Adding vermiculite or perlite to the soil mix can also enhance moisture retention and drainage. These lightweight materials create air pockets in the soil, preventing compaction and promoting healthy root growth.
Creating a Planting Medium: Supporting Root Growth
The type of planting medium you use under stones will depend on the types of plants you intend to grow. For succulents and rock garden plants, a well-draining mix of sand, gravel, and compost is ideal. For moisture-loving plants, a richer mix with more organic matter is preferable.
Consider adding mycorrhizal fungi to the planting medium. These beneficial fungi form symbiotic relationships with plant roots, enhancing nutrient uptake and improving plant health. Mycorrhizal fungi are particularly beneficial for plants growing in nutrient-poor soils.
Selecting Plants for Under Stones
The choice of plants to grow under stones depends on several factors, including your climate, soil type, and aesthetic preferences. Consider plants that are well-suited to growing in rocky or gravelly conditions and that can tolerate drought.
Rock Garden Plants: Embracing the Alpine Aesthetic
Rock gardens are designed to mimic alpine environments, featuring plants that thrive in rocky, well-drained soils. Sedums and sempervivums are popular choices for rock gardens, known for their drought tolerance and attractive foliage. Other suitable plants include thyme, creeping phlox, and aubrieta.
Consider the size and growth habit of the plants you select. Choose plants that will complement the stones and create a visually appealing composition. Avoid plants that are too aggressive or invasive, as they can quickly outcompete other plants.
Shade-Tolerant Plants: Thriving in Low Light
If the stones are located in a shady area, select plants that can tolerate low light conditions. Hostas, ferns, and astilbes are excellent choices for shade gardens, providing lush foliage and delicate blooms. Other suitable plants include bleeding hearts, lungwort, and woodland phlox.
Ensure the soil is well-drained, as shade gardens can be prone to waterlogging. Amend the soil with plenty of organic matter to improve drainage and provide nutrients.
Native Plants: Supporting Local Ecosystems
Incorporating native plants into your garden is a great way to support local ecosystems and attract pollinators. Native plants are adapted to the local climate and soil conditions, making them more resilient and requiring less maintenance. Research the native plants that are suitable for your area and select those that will thrive under stones.
Consider the ecological benefits of the plants you choose. Some plants are particularly attractive to pollinators, such as bees and butterflies. Others provide food and shelter for birds and other wildlife.
Attracting Wildlife Under Stones
Stones can provide valuable habitat for a variety of wildlife, including insects, amphibians, and reptiles. Creating a welcoming environment under stones can enhance biodiversity and contribute to a healthy ecosystem.

Many insects, such as beetles, spiders, and ants, seek shelter under stones. Providing a layer of leaf litter or wood chips under the stones can create a more attractive habitat for these creatures. Avoid using pesticides or herbicides, as these can harm beneficial insects.
Consider adding a small water source near the stones, such as a shallow dish of water with pebbles for insects to land on. This will provide a source of hydration, especially during dry periods.
Providing Shelter for Amphibians and Reptiles
Amphibians and reptiles, such as frogs, toads, and lizards, often seek refuge under stones to escape predators or extreme temperatures. Creating a cool, moist environment under the stones can make them more attractive to these animals. Place the stones in a shady area and ensure the soil is kept consistently moist.
Avoid disturbing the stones unnecessarily, as this can disrupt the animals’ habitat. If you need to move the stones, do so carefully and replace them as soon as possible.
Maintenance and Care
Maintaining the habitat under stones is essential for ensuring its long-term health and vitality. Regular weeding, watering, and fertilization will help keep the plants thriving and the ecosystem flourishing.
Weeding and Pest Control
Regular weeding is essential for preventing unwanted plants from outcompeting the desired species. Remove weeds by hand or use a hoe to cultivate the soil. Avoid using herbicides, as these can harm beneficial insects and plants.
Monitor the plants for signs of pests or diseases. Treat any infestations promptly using organic pest control methods, such as insecticidal soap or neem oil.
Watering and Fertilization
Water the plants regularly, especially during dry periods. Ensure the soil is evenly moist but not waterlogged. Avoid overwatering, as this can lead to root rot.
Fertilize the plants as needed, using a balanced organic fertilizer. Apply fertilizer in the spring and fall to provide a steady source of nutrients.
