Both landscaping stone and organic mulch help to foster growth in your garden. They help to make your flowers “pop” by adding a more neutral background that contrasts in color. They also reduce weeds by blocking light to unwanted plants. So, if you’re sold on stones and mulch, which one do you choose? Should you be using stones or mulch in planting beds? How do you know what’s right for your planting beds? We’ll walk you through the benefits of each, so you have all the information to decide.
Mulch is defined as any organic material that is used to top planting beds. When you add mulch to your garden, the soil will be able to retain more moisture than it otherwise would. Mulch improves the soil’s structure, drainage, and nutrient-holding capacity as it decomposes. Because mulch will decompose over time, you will need to replace it every year (sometimes twice a year). However, be careful not to add too much mulch. Adding more than 2 to 3 inches can do more harm than good.
When you’ve added mulch to your planting beds, your plants will also remain cooler in the summer and be protected from frost in the winter. Additionally, mulch helps suppress weeds, which take up all of the nutrients that are intended to nourish your plants.
Types of mulch
If mulch sounds like a healthy route for your garden, do your research! Not all mulches are created the same. Some are better for certain climates and others are a better investment because they last longer.
Bark, shredded or chipped
These types of mulches are best around trees and shrubs. They tend to last longer than finer organic mulches. It has an aesthetic appeal and is less likely to blow away if you live in a windy climate. It is also readily available in most areas.
This is an incredibly popular type of mulch in the Southeastern United States. It has a natural appearance and is lightweight. This makes it easy to lay and also increases soil acidity. It’s low maintenance as it only needs to be replaced every couple of years. It is good for high temperatures and protects the roots of your plants. It comes from naturally fallen pine needs and helps control soil erosion. However, this mulch is NOT the best for weed control and is not recommended in dry climates because there is a risk of wildfire.
This type of mulch is deemed “nature’s favorite” because it can be used pretty much anywhere. It is low-cost or free, which is a huge benefit if you’re on a budget. It’s ideal for a woodland style landscape. You can spread a layer in your garden in the fall, and it will decompose during the winter. Thus, you’ll need to be on top of maintaining it. Yet, with the low prices, it shouldn’t be as much of a hassle.
This type of mulch is most popular in vegetable gardens as it can help keep paths or dirt areas less muddy than they would otherwise be. Straw is a good home for beneficial insects who can move around in it. It can also keep less helpful pests under control. Straw will decompose slowly over time, so you’ll need to replace it periodically.
This type of mulch sounds like exactly what it is. It’s made from recycled rubber material, and it’s often used to create pathways and trails or may even be used at public parks or on playgrounds. It’s a great choice for ground cover, and it is more permanent than wood mulch. However, despite reducing fungal growth and acting as a weed barrier, it does nothing to improve the soil. It is non-porous and does not absorb moisture, but it is more effective at retaining soil moisture.
Compost mulch is ideal for vegetable gardens and flower beds as it is made out of organic material. If you add this type of mulch to flower beds, you help to improve the soil for future growth.
Landscape stones are used in an area to make it attractive and functional for ground cover. They’re often selected because they’re durable and resistant to losing their color. They aren’t scattered by wind or rain, and they can help keep the soil in place and moist when used around trees or shrubs.
Often, landscape stones are used for garden pathways or as an alternative to pavement or concrete. Because landscape stones come in a variety of colors or textures, you can select which one fits your tastes. When selected as a décor element, it adds color and character to your landscape.
Because landscape stones are sources from riverbeds, they can range in size from pea-sized to golf-ball-sized stones. The color, size, texture, and shape will vary. Drainage issues can often be solved by incorporating landscape stones as mulch into your landscape design.
Landscape stones are ideal for high-traffic areas, especially those where pedestrians tend to take short cuts. While mulch will look obviously trampled, stones tend to stay in place and require little to no maintenance. If you’re looking to put down a type of mulch and forget about it, landscaping stones are your best bet. They may be more expensive (2 to 3 times as much as an application of mulch!), but they last much longer, don’t break down, and don’t need to be replaced every single year.
If you’re leaning towards landscaping rocks, make sure you have the right type of plants or features for it. For example, landscaping stones are a great background for water fountains and features. Succulents also do particularly well with landscaping stones. Flowers, however, don’t thrive in beds with rocks as well. This is because rock beds tend to be naturally warmer than beds of mulch, so any plant nestled within it needs to be able to withstand the heat. Rocks are also not the best under trees that drop a lot of leaves or debris as you’ll find yourself trying to clean out your rocks constantly.
A few final tips that will confirm that rocks are what you’re looking for. Rocks require steel edging or a raised concrete barrier in order to prevent stray rocks from shifting into turf areas. This will allow your landscaping to remain neat and the stones to do their jobs. All that said, once you put it down, it’ll be harder to transfer or remove, so make sure you know what you’re doing!
