6 Best Cedar Chips For Repelling Insects Around Fruit Trees Without Chemicals
Safeguard your fruit trees from pests without chemicals. Our guide details the 6 best cedar chips, a natural and effective insect repellent for any orchard.
You walk out to your young apple trees and see it: the tell-tale curling leaves and sticky residue of an aphid invasion. It’s a common frustration, and the temptation is to reach for a chemical spray. But for those of us trying to build a healthy, self-sustaining system, there are better, more integrated ways to manage pests. Using cedar chips as a mulch is one of the most effective, low-effort strategies for creating a first line of defense around your valuable fruit trees.

How Cedar Mulch Naturally Deters Orchard Pests
Let’s be clear: cedar mulch isn’t magic. It works because of the natural oils present in the wood, particularly thujone, which has a strong aroma that many insects find irritating and disruptive. This scent can confuse pests like codling moths looking for a place to lay eggs and deter ants from farming aphids on the tender new growth of your trees. It creates a "no-go" zone that encourages them to move on to a more welcoming environment.
The physical texture of the chips also creates a difficult barrier for soft-bodied pests. Slugs and snails, for instance, find the sharp, dry edges of cedar chips unpleasant to crawl over, often turning back before they can reach the trunk. This dual-action approach—both aromatic and physical—is what makes cedar a powerful tool in a chemical-free orchard.
Beyond pest control, cedar mulch serves several other critical functions. It suppresses weeds that compete for water and nutrients, insulates the soil to protect roots from temperature extremes, and helps retain moisture, reducing your watering workload. Think of it not just as a pest repellent, but as a multi-purpose ground cover that supports the overall health and resilience of your trees.
Woodsmith Red Cedar Chips: Aromatic & Long-Lasting
Provide a comfortable and clean space for your pets with PETSPICK Red Cedar Bedding. This 99.9% dust-free, all-natural cedar bedding absorbs moisture and odors, keeping kennels and stables fresh.
When your primary goal is long-term pest deterrence with minimal reapplication, the size and quality of the chip matter. Woodsmith Red Cedar Chips are typically larger and chunkier than many other brands. This is a significant advantage for the time-strapped farmer. The larger surface area means the aromatic oils are released more slowly, extending the pest-repelling effect through the season.
The slow decomposition rate of these thicker chips means you won’t have to top up your mulch layer as frequently. This saves both time and money over the life of your orchard. While a fresh layer is potent, the lingering scent from older chips continues to provide a baseline level of protection.
The main tradeoff with larger chips is the physical barrier they create. While excellent for general deterrence and weed suppression, the gaps between the chips can be large enough for smaller insects to navigate. For a truly dense mat against tiny crawlers, you might need a finer material, but for a robust, long-lasting aromatic shield, Woodsmith’s larger format is hard to beat.
Vigoro Premium Cedar Mulch for Moisture Control
Enjoy natural cedar shavings for moisture retention in plants, odor control in pet bedding, or as a subtle air freshener. This 4-quart bag of USA-made cedar is hand-packed for quality.
Young fruit trees are incredibly thirsty, and inconsistent watering is a common reason they fail to establish. Vigoro’s cedar mulch is often formulated with moisture retention as a primary benefit. Its blend of chips and smaller shreds knits together to form a protective blanket over the soil, significantly reducing evaporation from the sun and wind.
This focus on moisture control makes it an excellent choice for new plantings or for orchards in drier climates. By keeping the soil consistently moist, you reduce stress on the tree, making it naturally more resistant to pests and diseases in the first place. A healthy, well-hydrated tree is always your best defense.
While its pest-repelling aroma is effective, its standout feature is this dual-purpose functionality. You’re not just deterring insects; you’re actively improving the growing conditions for your trees. If you find yourself constantly dragging hoses around your property, choosing a mulch specifically designed for water conservation can be a game-changer.
Playsafer Cedar Mulch: Uniform Chip Size Option
It might seem odd to look at playground surfacing for your orchard, but there’s a practical reason to consider it. Playsafer Cedar Mulch is engineered to have a very uniform chip size and to be free of splinters and dust. This consistency provides a predictable and even coverage that’s easy to spread.
For the hobby farmer who values a neat appearance, this uniformity is a major plus. It creates a clean, professional look around the base of each tree. More practically, the consistent chip size creates a reliable barrier without the weak spots you might find in a more varied, rustic mulch.
The primary consideration here is cost. Because it undergoes more processing to meet playground safety standards, Playsafer is often more expensive per cubic foot. You have to decide if the aesthetic and ease of application are worth the premium. For a small number of specimen trees visible from the house, it might be; for a long row of trees out in the back field, a more economical option is likely the better choice.
Scotts Nature Scapes Cedar: Rich Color & Aroma
Accessibility is a real factor in farming. Scotts Nature Scapes is a brand you can find at almost any big-box store, making it a convenient option when you need mulch now. It’s known for its strong initial aroma and rich, often color-enhanced, reddish-brown hue that holds up well against sun-fading.
The immediate, powerful cedar scent is great for providing a strong initial deterrent when you first apply it, especially if you’re dealing with an active pest issue. The color enhancement, while purely aesthetic, can help integrate your orchard into a more landscaped part of your property, giving it a tidy, intentional look.
Be aware that "color-enhanced" means a dye has been added. While Scotts and other major brands use dyes that are safe for plants, soil, and pets, it’s a departure from a purely "natural" product. For many, this is a non-issue, but if you are a strict organic purist, you may prefer an undyed option. The convenience and strong initial performance, however, make it a solid, practical choice for most.
Greenes Fence Co. Cedar Mulch for Large Orchards
Once your orchard grows beyond a few backyard trees, buying mulch in small bags becomes impractical and expensive. This is where bulk options like the compressed bales from Greenes Fence Co. come in. These products are designed for utility and scale, giving you the most coverage for your dollar.
When you buy in bulk, you’re prioritizing quantity over cosmetic perfection. The consistency of the mulch might be more varied, with a mix of chips, shreds, and fine material. This isn’t a bad thing for pest control—in fact, the varied texture can create an even more complex barrier for insects to cross.
The main benefit is economic. You can mulch an entire row of a dozen trees for the price of what a few small, premium bags would cost. For anyone managing a small-scale orchard, buying for coverage and cost-effectiveness is the smart play. You sacrifice some uniformity, but you gain the ability to properly mulch every tree without breaking the budget.
CedarCide Original: Finely Shredded Pest Barrier
For targeting specific, persistent pests like slugs, a change in texture can make all the difference. CedarCide Original, and similar finely shredded "gorilla hair" style mulches, create a dense, interlocking mat. This texture is extremely difficult for soft-bodied pests to move across, acting as a formidable physical barrier.
This type of mulch is also excellent for use on slopes or in windy areas where looser chips might blow or wash away. The fibers knit together, holding the soil in place while still allowing water to penetrate. The increased surface area of the fine shreds also releases a very strong cedar aroma, providing a powerful repellent effect.
The downside to finely shredded mulch is that it breaks down more quickly than larger chips, requiring more frequent top-ups to maintain its depth and effectiveness. It can also sometimes compact and form a water-repellent crust if it gets too dry. However, for creating an almost impenetrable fortress at the base of your trees, the unique texture of a shredded cedar mulch is unmatched.
Applying Cedar Mulch Correctly Around Your Trees
Simply dumping cedar chips around your trees can do more harm than good. Proper application is key to reaping the benefits without causing unintended problems like collar rot or creating a haven for voles. The process is simple but non-negotiable.
First, clear all grass and weeds from a three-foot diameter circle around the tree’s trunk. Weeds compete directly with your tree for resources. Next, apply a layer of cedar mulch that is two to three inches deep. Any deeper, and you risk suffocating the surface roots by limiting oxygen exchange with the soil.
Most importantly, pull the mulch back from the trunk, leaving a 4- to 6-inch gap all the way around. Piling mulch directly against the bark—a common mistake known as a "mulch volcano"—traps moisture, which invites fungal diseases and decay right where the tree is most vulnerable. This gap keeps the root flare dry and healthy, ensuring your natural pest solution doesn’t create a much bigger problem. A quick rake once or twice a season can also stir up the chips and refresh the pest-repelling aroma.
Choosing the right cedar mulch isn’t about finding a single "best" product, but about matching the material to your specific goals. Whether you need long-lasting aroma, superior moisture control, or a cost-effective bulk solution, there’s an option that fits. By applying it correctly, you’re not just repelling pests; you’re building a healthier, more resilient orchard from the ground up, one tree at a time.
