Concrete has become a popular and versatile material for many garden projects, and it’s easy to see why. You can use it to create beautiful patios, neat pathways, sturdy retaining walls, and even custom planters. However, before you start mixing, there are a few important things to consider. Thinking through your project beforehand will help you achieve the best possible results for your outdoor space.
Here’s what to know before using concrete in your garden.
Consider Your Garden’s Overall Design
Your garden’s aesthetic should guide your concrete decisions. If you have a modern garden, then you’ll probably want concrete elements with defined lines, cool colors, and polished surfaces. On the other hand, if you’ve curated a cottage-like aesthetic in your backyard, then textured finishes, pavers, warmer colors, and softer edges will look nicer.
Also, think about the existing materials in your yard, like wood, stone, brick, or metal, and how the concrete will harmonize with them.
Think About Drainage and Water Runoff
Proper drainage is crucial for a healthy garden, and adding non-porous surfaces like concrete can affect it. So when you plan your project, consider where rainwater will go. You might need to incorporate slight slopes, install drains, add gravel-filled gaps between pavers, or use permeable concrete to allow water to soak into the ground. These measures will help prevent water from pooling, which could damage plant roots and your concrete work.
Choose the Right Type of Concrete
Different projects require different types of concrete. Standard ready-mix concrete is great for large slabs like patios, but you might prefer using pre-cast pavers for a walkway or a specific high-strength mix for a retaining wall.
Additionally, think about adding color and texture. There are many pigments and stains available. Learning how to pick stain colors for your concrete can add a unique touch that matches your garden’s palette.
Be Mindful of Plants and Soil
Concrete can also impact the soil and plants nearby. The pouring and curing process can be messy, so it’s wise to protect existing plants from spills. More importantly, concrete can raise the pH of the surrounding soil, making it more alkaline. This change can affect acid-loving plants. Make sure to test your soil’s pH after the concrete has cured and amend it if necessary to keep your plants happy.
Plan for Long-Term Maintenance
While concrete is very durable, another thing to know before using it in your garden is that it does require some upkeep to look its best. You will need to clean it periodically to remove dirt, moss, and algae. Applying a sealer every few years can also protect the surface from stains, water damage, and cracking. But be prepared for the possibility of cracks developing over time due to ground movement or temperature changes, and have a plan for how you’ll repair them.
