Wood Chips in Yard: 5 Pro Tips for Lasting Landscape Fill
1. Choosing the Right Wood Chip: Know Your Mulch
The first step to a lasting wood chip landscape is selecting the right type of wood chip. This isn’t as simple as grabbing the cheapest bag at your local hardware store. The species of wood, the size of the chips, and whether they’re composted all play a crucial role in their performance and longevity.
Different Types of Wood Chips:
-
Hardwood Chips: These are generally more durable and decompose slower than softwood chips. They’re a good choice for pathways and areas where you want long-lasting coverage. Common hardwoods include oak, maple, and birch. I’ve found that oak chips, in particular, hold up exceptionally well, resisting decomposition and maintaining their color longer.
-
Softwood Chips: Pine, fir, and spruce are common softwoods. They tend to break down faster, enriching the soil more quickly. This can be beneficial for garden beds but less ideal for pathways. I once used cedar chips around my blueberry bushes, and they not only provided excellent weed control but also helped acidify the soil, creating the perfect growing environment.
-
Arborist Wood Chips: These are a mixed bag (literally!). They’re typically a combination of whatever the local tree service has been chipping recently. This can include leaves, twigs, and branches, as well as wood from various tree species. While they can be a cost-effective option, their quality and longevity can be unpredictable. When using arborist chips, I always recommend letting them sit in a pile for a few weeks to allow some initial composting to occur. This helps reduce the risk of nitrogen depletion in your soil.
-
Composted Wood Chips: These have been partially decomposed, making them more nutrient-rich and less likely to deplete nitrogen from the soil. They’re a great choice for amending garden beds and improving soil health. I’ve used composted wood chips to revitalize tired vegetable gardens with great success.
Size Matters:
The size of the wood chips also impacts their performance. Larger chips tend to decompose slower and provide better weed control, while smaller chips break down more quickly and add more organic matter to the soil.
- Coarse Chips: These are typically 2-4 inches in size and are ideal for pathways and areas where you want long-lasting coverage.
- Medium Chips: These are 1-2 inches in size and are a good all-around choice for garden beds and general landscaping.
- Fine Chips: These are less than 1 inch in size and are best used as a soil amendment or for top dressing lawns.
Data-Backed Insights:
According to a study by Washington State University, hardwood chips decompose at a rate of approximately 5-10% per year, while softwood chips decompose at a rate of 10-20% per year. This means that hardwood chips can last twice as long as softwood chips in your landscape.
Expert Insight:
“When choosing wood chips, consider the long-term impact on your soil,” says Dr. Linda Chalker-Scott, an Extension Urban Horticulturist at Washington State University. “While softwood chips break down faster and add more nutrients, they can also temporarily deplete nitrogen from the soil. Hardwood chips, on the other hand, decompose slower and provide more long-term weed control.”
Personal Story:
I once made the mistake of using fresh, uncomposted arborist chips around my tomato plants. Within a few weeks, the plants started to yellow and their growth was stunted. I later learned that the fresh wood chips were actively drawing nitrogen from the soil, depriving my tomatoes of this essential nutrient. I quickly removed the chips and added a nitrogen-rich fertilizer, and the plants eventually recovered. This experience taught me the importance of understanding the properties of different wood chips and their potential impact on plant health.
Actionable Tip:
Before you buy, ask your supplier about the source of the wood chips and whether they’ve been composted. If you’re unsure, it’s always best to err on the side of caution and choose a known hardwood variety.
2. Preparing the Ground: Laying the Foundation for Success
Proper ground preparation is essential for creating a lasting wood chip landscape. It’s not enough to simply dump wood chips on top of existing soil or weeds. You need to create a solid foundation that will prevent weed growth, promote drainage, and ensure the wood chips stay in place.
Steps for Preparing the Ground:
-
Clear the Area: Remove any existing vegetation, rocks, and debris from the area you plan to cover with wood chips. This may involve pulling weeds by hand, using a hoe, or applying an herbicide. I prefer to use a combination of hand-pulling and hoeing, as it’s the most environmentally friendly approach.
-
Level the Ground: Use a rake or shovel to level the ground and create a smooth, even surface. This will help ensure the wood chips are applied at a uniform depth. I often use a laser level to ensure the ground is perfectly level, especially for larger areas.
-
Amend the Soil (If Necessary): If your soil is compacted or nutrient-poor, consider amending it with compost or other organic matter. This will improve drainage and provide a more hospitable environment for plants. I typically add a 2-3 inch layer of compost to the soil before applying wood chips, especially in garden beds.
-
Install a Weed Barrier (Optional): While not always necessary, a weed barrier can provide an extra layer of protection against weed growth. There are several types of weed barriers available, including landscape fabric, cardboard, and newspaper. I prefer to use landscape fabric, as it’s durable and allows water to drain through.
- Landscape Fabric: This is a synthetic material that is designed to block weed growth while allowing water and air to pass through. It’s a good choice for areas where you want long-term weed control. When using landscape fabric, I always overlap the edges by at least 6 inches to prevent weeds from growing through the seams.
- Cardboard: This is a natural and biodegradable option that can be effective at suppressing weeds. However, it will eventually decompose, so it’s not as long-lasting as landscape fabric. When using cardboard, I remove any tape or labels and overlap the pieces by at least 12 inches.
- Newspaper: This is another natural and biodegradable option, but it’s even less durable than cardboard. It’s best used in areas where you don’t expect heavy foot traffic. When using newspaper, I use at least 6-8 layers and wet it down thoroughly to help it stay in place.
-
Water the Soil: Before applying wood chips, water the soil thoroughly. This will help settle the soil and provide moisture for plants.
Data-Backed Insights:
According to a study by the University of California, Davis, proper ground preparation can reduce weed growth by up to 80%. This means that taking the time to prepare the ground properly can significantly reduce the amount of time and effort you spend on weeding in the future.
Expert Insight:
“Don’t underestimate the importance of ground preparation,” says Joe Lamp’l, a gardening expert and host of the PBS show “Growing a Greener World.” “A well-prepared foundation is the key to a successful and long-lasting wood chip landscape. It’s like building a house – if you don’t have a solid foundation, the whole thing will eventually crumble.”
Personal Story:
I once helped a friend install a wood chip pathway in her backyard. We skipped the ground preparation step, thinking it would save us time. Within a few weeks, weeds started sprouting through the wood chips, and the pathway looked like a mess. We ended up having to remove all the wood chips, prepare the ground properly, and reinstall the chips. It was a lot of extra work, and it taught us a valuable lesson about the importance of ground preparation.
Actionable Tip:
Take the time to prepare the ground properly before applying wood chips. It will save you time and effort in the long run and ensure your landscape looks great for years to come.
3. Applying Wood Chips: Depth and Technique
The depth at which you apply wood chips is crucial for achieving the desired results. Too thin, and weeds will sprout through; too thick, and you risk compaction and poor drainage. The ideal depth depends on the type of wood chip, the intended use, and the specific needs of your plants.
General Guidelines for Wood Chip Depth:
-
Pathways: 4-6 inches. This depth provides a stable walking surface and effectively suppresses weed growth. I typically aim for a 5-inch depth for pathways, as it provides a good balance between stability and cost.
-
Garden Beds: 2-4 inches. This depth provides adequate weed control while allowing water and air to reach the soil. I adjust the depth based on the type of plants I’m growing. For shallow-rooted plants like lettuce, I use a 2-inch depth. For deeper-rooted plants like tomatoes, I use a 4-inch depth.
-
Around Trees and Shrubs: 3-4 inches. This depth helps retain moisture, regulate soil temperature, and protect the roots from damage. When applying wood chips around trees and shrubs, I always leave a 2-3 inch gap around the base of the trunk to prevent rot.
Application Techniques:
-
Even Distribution: Use a rake or shovel to distribute the wood chips evenly over the prepared area. Avoid piling the chips up against the base of plants or trees, as this can promote rot. I always take my time to ensure the chips are evenly distributed, as this makes a big difference in the overall appearance of the landscape.
-
Layering: For garden beds, consider layering the wood chips with other organic materials, such as compost or shredded leaves. This will provide a richer and more nutrient-dense environment for plants. I often create a lasagna garden by layering cardboard, compost, shredded leaves, and wood chips.
-
Compacting (Optional): For pathways, you may want to compact the wood chips using a roller or tamper. This will help create a more stable and durable surface. I typically compact the wood chips after applying them, especially in high-traffic areas.
Data-Backed Insights:
According to a study by the University of Minnesota, applying wood chips at a depth of 4 inches can reduce weed growth by up to 90%. This highlights the importance of applying wood chips at the correct depth for effective weed control.
Expert Insight:
“The key to a successful wood chip application is to find the right balance,” says Melinda Myers, a gardening expert and author of numerous gardening books. “You want enough wood chips to suppress weeds and retain moisture, but not so much that you suffocate your plants or create drainage problems.”
Personal Story:
I once applied wood chips too thickly around my rose bushes. The bushes started to yellow and their growth was stunted. I later learned that the thick layer of wood chips was preventing air from reaching the roots, causing them to suffocate. I removed some of the wood chips, and the bushes eventually recovered. This experience taught me the importance of applying wood chips at the correct depth and avoiding piling them up against the base of plants.
Actionable Tip:
Use a measuring stick or ruler to ensure you’re applying wood chips at the correct depth. It’s better to err on the side of too little than too much, as you can always add more later if needed.
4. Maintaining Your Wood Chip Bed: Keeping It Fresh
Once you’ve applied your wood chips, the work isn’t over. Regular maintenance is essential for keeping your wood chip bed looking fresh and functional. This includes replenishing the chips as they decompose, removing weeds that manage to sprout through, and addressing any drainage issues that may arise.
Maintenance Tasks:
-
Replenishing: Wood chips will naturally decompose over time, so you’ll need to replenish them periodically to maintain the desired depth. I typically replenish my wood chips every 1-2 years, depending on the type of wood chip and the climate.
-
Weeding: Even with proper ground preparation and a thick layer of wood chips, some weeds may still manage to sprout through. Remove these weeds promptly to prevent them from spreading. I prefer to pull weeds by hand, but you can also use a weeding tool or herbicide.
-
Raking: Rake the wood chips periodically to keep them looking neat and tidy. This will also help prevent compaction and improve drainage. I typically rake my wood chips every few weeks, especially after heavy rain or wind.
-
Addressing Drainage Issues: If you notice water pooling in certain areas of your wood chip bed, you may have a drainage issue. This can be caused by compacted soil, poor grading, or clogged drainage pipes. Address any drainage issues promptly to prevent root rot and other problems. I often use a garden fork to aerate the soil and improve drainage.
-
Turning (Optional): For garden beds, you may want to turn the wood chips periodically to promote decomposition and improve soil health. This is especially important if you’re using fresh, uncomposted wood chips. I typically turn my wood chips every few months, using a garden fork or shovel.
Data-Backed Insights:
According to a study by the University of Georgia, regular maintenance can extend the lifespan of wood chips by up to 50%. This means that taking the time to maintain your wood chip bed can save you money in the long run by reducing the frequency with which you need to replenish the chips.
Expert Insight:
“Maintenance is the key to a long-lasting wood chip landscape,” says P. Allen Smith, a gardening expert and host of numerous gardening shows. “It’s like taking care of a car – if you don’t perform regular maintenance, it will eventually break down.”
Personal Story:
I once neglected to maintain my wood chip pathway. Weeds started sprouting through, the chips became compacted, and the pathway looked like a disaster. I ended up having to remove all the wood chips, weed the area, and reinstall the chips. It was a lot of extra work, and it taught me the importance of regular maintenance.
Actionable Tip:
Set a schedule for maintaining your wood chip bed and stick to it. This will help ensure your landscape looks great for years to come. I use a calendar reminder to replenish, weed, and rake my wood chips on a regular basis.
5. Considering the Specific Needs of Your Plants: Tailoring Your Approach
Different plants have different needs, and your wood chip application should reflect that. Some plants prefer acidic soil, while others prefer alkaline soil. Some plants need well-drained soil, while others can tolerate wetter conditions. Understanding the specific needs of your plants is essential for choosing the right type of wood chip and applying it in a way that promotes healthy growth.
Factors to Consider:
-
Soil pH: Some wood chips, such as pine needles, can acidify the soil. This can be beneficial for acid-loving plants like blueberries, azaleas, and rhododendrons. Other wood chips, such as hardwood chips, have a neutral pH. Consider the pH preferences of your plants when choosing wood chips.
-
Drainage: Some plants need well-drained soil, while others can tolerate wetter conditions. If you’re growing plants that need well-drained soil, avoid applying wood chips too thickly, as this can trap moisture and lead to root rot.
-
Nutrient Needs: Some plants are heavy feeders, while others are light feeders. If you’re growing heavy feeders, consider amending the soil with compost or other organic matter before applying wood chips. This will provide the plants with the nutrients they need to thrive.
-
Sun Exposure: Some plants prefer full sun, while others prefer shade. If you’re growing plants in full sun, wood chips can help retain moisture and regulate soil temperature. If you’re growing plants in shade, avoid applying wood chips too thickly, as this can create a damp environment that promotes fungal growth.
Examples:
- Blueberries: These plants prefer acidic soil, so pine needles or oak chips are a good choice.
- Tomatoes: These plants are heavy feeders, so amending the soil with compost before applying wood chips is recommended.
- Hostas: These plants prefer shade and well-drained soil, so avoid applying wood chips too thickly.
Data-Backed Insights:
According to a study by the University of Florida, using the wrong type of wood chip can reduce plant growth by up to 20%. This highlights the importance of considering the specific needs of your plants when choosing wood chips.
Expert Insight:
“The best way to ensure your plants thrive is to tailor your wood chip application to their specific needs,” says Barbara Pleasant, a gardening expert and author of numerous gardening books. “This may involve choosing a different type of wood chip, adjusting the depth, or amending the soil.”
Personal Story:
