My Own Battles with Bittersweet: A Personal Perspective

I’ve personally wrestled with bittersweet infestations on several properties I’ve managed, both for timber harvesting and firewood production. I remember one particularly challenging situation on a heavily wooded lot I acquired a few years back. The bittersweet had completely engulfed several mature oak trees, making timber harvesting impossible without first addressing the vine infestation. I learned firsthand the importance of careful planning, proper herbicide selection, and diligent application. I also quickly realized that underestimating the cost of such a project is a common mistake. What I thought would be a quick and inexpensive fix turned into a multi-year effort requiring significant investment in time and resources.

Variable Factors Affecting Project Costs

Before diving into specific tactics and costs, it’s crucial to acknowledge the variables that can significantly impact your project’s budget:

• Infestation Severity: A light infestation covering a few saplings will be far less costly to treat than a heavy infestation engulfing mature trees across a large area.
• Property Size: The larger the area infested with bittersweet, the more herbicide you’ll need, and the more time and labor will be required.
• Accessibility: If the infested area is difficult to access with equipment, you’ll likely need to rely on manual labor, which will increase costs.
• Terrain: Steep slopes and rocky terrain can make herbicide application more challenging and time-consuming.
• Wood Species and Number of Trees Affected: The size and number of trees impacted by the bittersweet influence the amount of herbicide required for basal bark or cut-stump treatments.
• Herbicide Choice: Different herbicides have different costs, effectiveness, and application requirements.
• Labor Costs: If you hire professionals to apply the herbicide, labor costs will be a significant factor.
• Equipment Costs: You may need to purchase or rent equipment such as sprayers, chainsaws, and personal protective equipment (PPE).
• Permits and Regulations: Some areas may require permits for herbicide application, which can add to the overall cost.
• Follow-Up Treatments: Bittersweet is persistent, and follow-up treatments are often necessary to prevent re-infestation. This needs to be factored into your budget.
• Disposal Costs: While not always applicable, if you are removing large amounts of bittersweet biomass, you may need to factor in disposal costs, especially if local regulations prohibit burning.

5 Pro Tree-Removal Tactics for Bittersweet Control (with Detailed Cost Breakdown)

Here are five effective tactics for removing bittersweet, along with a detailed breakdown of the costs associated with each:

Tactic 1: Cut-Stump Herbicide Application

This tactic involves cutting the bittersweet vines near the base and immediately applying herbicide to the freshly cut stump. It’s particularly effective for larger vines and can prevent re-sprouting.

• How it Works: Cut the vine as close to the ground as possible. Within minutes (ideally seconds), apply a concentrated herbicide solution to the entire cut surface of the stump. The herbicide is absorbed into the root system, killing the plant.
• Best For: Larger vines (greater than ½ inch in diameter), areas where you want to avoid spraying foliage, and situations where you need to prevent re-sprouting.
• Herbicide Choice: Glyphosate (e.g., Roundup, Rodeo – for aquatic environments) or Triclopyr (e.g., Garlon, Brush-B-Gon). Triclopyr is generally more effective on woody plants like bittersweet.
• Equipment Needed: Chainsaw or pruning shears, herbicide sprayer (a small hand-held sprayer is sufficient), personal protective equipment (PPE) – gloves, eye protection, long sleeves, long pants.

Cost Breakdown (per infested tree/area):

• Herbicide: I typically use a concentrated Triclopyr ester product, such as Garlon 4 Ultra, for cut-stump treatments. A quart (32 oz) of Garlon 4 Ultra typically costs between $50 and $75, depending on the supplier and location. For a cut-stump application, I mix it at a rate of 25% to 50% with a suitable carrier (e.g., water or diesel fuel – check the label for specific recommendations). Let’s assume a 50% mix. A quart of herbicide mixture will treat approximately 20-30 cut stumps, depending on the size of the vines. Therefore, the herbicide cost per tree/area is approximately $2.50 – $3.75.
• Chainsaw/Pruning Shears: If you already own a chainsaw or pruning shears, there’s no additional cost. However, factor in the cost of fuel and oil for the chainsaw. A gallon of pre-mixed fuel typically costs around $20. A chainsaw will consume roughly 0.25 gallons of fuel per hour of use. If you spend 15 minutes (0.25 hours) cutting vines around a single tree, the fuel cost is approximately $5.00. Pruning shears have minimal cost.
• PPE: A good pair of chemical-resistant gloves costs around $10, and eye protection costs around $5. These are reusable, so the cost per tree is minimal, but factor in the initial purchase. Let’s allocate $0.50 per tree for PPE.
• Labor: If you’re doing the work yourself, the cost is your time. If you’re hiring someone, labor costs can vary widely depending on location and experience. Expect to pay between $30 and $75 per hour for skilled labor. If it takes 15 minutes (0.25 hours) to cut and treat the vines around a single tree, the labor cost would be $7.50 – $18.75.

Total Cost per Tree/Area (Cut-Stump Method):

• DIY: $2.50 (herbicide) + $5.00 (fuel) + $0.50 (PPE) = $8.00 – $9.25
• Hired Labor: $2.50 (herbicide) + $5.00 (fuel) + $0.50 (PPE) + $7.50 – $18.75 (labor) = $15.50 – $26.75

Important Note: These costs are estimates and can vary. Always get quotes from local suppliers and contractors.

Tactic 2: Basal Bark Herbicide Application

This tactic involves applying herbicide directly to the bark of the bittersweet vine, near the base. The herbicide is absorbed through the bark and into the plant’s system.

• How it Works: Mix a herbicide specifically labeled for basal bark application with a penetrating oil (check the herbicide label for recommended mixing ratios). Apply the mixture to the lower 12-18 inches of the vine’s bark, thoroughly wetting the bark.
• Best For: Vines up to 6 inches in diameter, areas where you want to avoid cutting vines, and situations where you want to treat multiple vines quickly.
• Herbicide Choice: Triclopyr ester (e.g., Garlon 4 Ultra) mixed with a penetrating oil.
• Equipment Needed: Herbicide sprayer (a backpack sprayer is ideal for larger areas), personal protective equipment (PPE) – gloves, eye protection, long sleeves, long pants.

Cost Breakdown (per infested tree/area):

• Herbicide: As mentioned before, a quart of Garlon 4 Ultra costs between $50 and $75. For basal bark application, I typically mix it at a rate of 15% to 20% with a penetrating oil, such as bark oil or diesel fuel (check the label for specific recommendations and regulations). Let’s assume a 20% mix. A quart of herbicide mixture will treat approximately 10-15 trees, depending on the size and number of vines. Therefore, the herbicide cost per tree/area is approximately $3.33 – $7.50.
• Penetrating Oil: A gallon of penetrating oil (e.g., bark oil) typically costs between $30 and $50. Since you’re mixing it with the herbicide, a gallon will go a long way. The oil cost per tree/area is approximately $1.00 – $2.50.
• Sprayer: A good quality backpack sprayer costs between $100 and $200. These are reusable, so the cost per tree is minimal, but factor in the initial purchase. Let’s allocate $0.25 per tree for sprayer depreciation.
• PPE: As before, let’s allocate $0.50 per tree for PPE.
• Labor: If it takes 10 minutes (0.17 hours) to apply the herbicide to the base of the vines around a single tree, the labor cost would be $5.00 – $12.75.

Total Cost per Tree/Area (Basal Bark Method):

• DIY: $3.33 (herbicide) + $1.00 (oil) + $0.25 (sprayer) + $0.50 (PPE) = $5.08 – $9.75
• Hired Labor: $3.33 (herbicide) + $1.00 (oil) + $0.25 (sprayer) + $0.50 (PPE) + $5.00 – $12.75 (labor) = $10.08 – $22.75

Important Considerations: Basal bark application is most effective during the dormant season (late fall to early spring) when the plant is not actively growing. Also, make sure to check the herbicide label for specific instructions and restrictions.

Tactic 3: Foliar Herbicide Application

This tactic involves spraying the leaves of the bittersweet vine with herbicide. It’s most effective for smaller vines and seedlings.

• How it Works: Mix a herbicide specifically labeled for foliar application with water (check the herbicide label for recommended mixing ratios). Apply the mixture to the leaves of the bittersweet vine, thoroughly wetting the foliage. Avoid spraying non-target plants.
• Best For: Smaller vines, seedlings, and areas where you can easily reach the foliage without damaging desirable plants.
• Herbicide Choice: Glyphosate or Triclopyr. Glyphosate is generally less selective and can harm non-target plants, so use it with caution.
• Equipment Needed: Herbicide sprayer (a backpack sprayer is ideal for larger areas), personal protective equipment (PPE) – gloves, eye protection, long sleeves, long pants.

Cost Breakdown (per infested tree/area):

• Herbicide: Glyphosate is typically cheaper than Triclopyr. A gallon of glyphosate concentrate costs between $30 and $50. For foliar application, I typically mix it at a rate of 1% to 2% with water. Let’s assume a 1.5% mix. A gallon of herbicide mixture will cover a significant area, potentially treating dozens of trees, depending on the size and density of the vines. Therefore, the herbicide cost per tree/area is approximately $0.50 – $2.00.
• Sprayer: As before, let’s allocate $0.25 per tree for sprayer depreciation.
• PPE: As before, let’s allocate $0.50 per tree for PPE.
• Labor: If it takes 5 minutes (0.08 hours) to spray the foliage of the vines around a single tree, the labor cost would be $2.50 – $6.25.

Total Cost per Tree/Area (Foliar Method):

• DIY: $0.50 (herbicide) + $0.25 (sprayer) + $0.50 (PPE) = $1.25 – $2.75
• Hired Labor: $0.50 (herbicide) + $0.25 (sprayer) + $0.50 (PPE) + $2.50 – $6.25 (labor) = $3.75 – $9.50

Important Considerations: Foliar application is most effective when the plants are actively growing and have a full canopy of leaves. Avoid spraying on windy days to prevent herbicide drift. Be extremely careful to avoid spraying non-target plants.

Tactic 4: Cut-and-Treat Aerial Vines

This tactic is a variation of the cut-stump method, but it focuses on the aerial vines that are climbing up trees. It’s particularly useful for protecting mature trees from being strangled by bittersweet.

• How it Works: Cut the bittersweet vines at a convenient height (e.g., chest height) to sever the connection between the aerial vines and the root system. Then, treat the cut stump of the aerial vine with herbicide, as described in Tactic 1. The aerial vines will eventually die and decompose.
• Best For: Protecting mature trees from being strangled by bittersweet, situations where you can’t reach the base of the vines, and areas where you want to avoid spraying foliage.
• Herbicide Choice: Glyphosate or Triclopyr.
• Equipment Needed: Chainsaw or pruning shears, herbicide sprayer, personal protective equipment (PPE).

Cost Breakdown (per infested tree):

The cost breakdown is similar to the cut-stump method (Tactic 1), but with a few key differences:

• Herbicide: The herbicide cost per tree is approximately $2.50 – $3.75.
• Chainsaw/Pruning Shears: The fuel cost for the chainsaw may be slightly higher, as you may need to reach higher to cut the vines. Let’s estimate $7.50 for fuel.
• PPE: Let’s allocate $0.50 per tree for PPE.
• Labor: If it takes 20 minutes (0.33 hours) to cut and treat the aerial vines on a single tree, the labor cost would be $10.00 – $24.75.

Total Cost per Tree (Cut-and-Treat Aerial Vines):

• DIY: $2.50 (herbicide) + $7.50 (fuel) + $0.50 (PPE) = $10.50 – $11.75
• Hired Labor: $2.50 (herbicide) + $7.50 (fuel) + $0.50 (PPE) + $10.00 – $24.75 (labor) = $20.50 – $35.25

Important Note: This tactic is most effective when combined with other control methods, such as treating the root system at the base of the vines.

Tactic 5: Integrated Approach – Combining Methods

In many cases, the most effective approach to bittersweet control is to combine multiple tactics. This is what I often refer to as an “integrated pest management” (IPM) strategy.

• How it Works: Assess the infestation and determine the best combination of tactics for your specific situation. For example, you might use the cut-stump method to treat large vines at the base of trees, the basal bark method to treat smaller vines, and the foliar application method to treat seedlings.
• Best For: Complex infestations with vines of varying sizes and densities.
• Herbicide Choice: A combination of Glyphosate and Triclopyr may be used, depending on the specific application.
• Equipment Needed: Chainsaw or pruning shears, herbicide sprayer (backpack and hand-held), personal protective equipment (PPE).

Cost Breakdown (per infested area):

The cost breakdown for an integrated approach will depend on the specific combination of tactics used. However, it’s generally more cost-effective in the long run, as it targets the infestation more effectively and reduces the need for repeated treatments.

Let’s assume you’re using a combination of cut-stump and foliar application. You’re treating 5 large vines with the cut-stump method and spraying the foliage of smaller vines and seedlings in a 100 sq ft area.

• Cut-Stump (5 vines): $2.50 (herbicide) * 5 = $12.50 + $5.00 (fuel) + $0.50 (PPE) = $18.00
• Foliar Application (100 sq ft): $1.00 (herbicide) + $0.25 (sprayer) + $0.50 (PPE) = $1.75
• Labor (Combined): Let’s assume it takes 45 minutes (0.75 hours) to complete both tasks. Labor cost = $22.50 – $56.25

Total Cost per 100 sq ft Area (Integrated Approach):

• DIY: $18.00 (cut-stump) + $1.75 (foliar) = $19.75
• Hired Labor: $19.75 + $22.50 – $56.25 (labor) = $42.25 – $76.00

Important Considerations: An integrated approach requires careful planning and execution. It’s essential to understand the strengths and weaknesses of each tactic and to choose the right combination for your specific situation.

General Tips for Cost Optimization and Budget Management

Here are some general tips to help you optimize costs and manage your budget effectively:

• Accurate Assessment: Before you start, take the time to accurately assess the extent of the bittersweet infestation. This will help you estimate the amount of herbicide you’ll need and the amount of labor required.
• Shop Around: Compare prices from different suppliers for herbicides, equipment, and labor.
• Buy in Bulk: If you have a large area to treat, consider buying herbicide in bulk to save money.
• Rent Equipment: If you don’t own the necessary equipment, consider renting it instead of buying it.
• DIY vs. Hire: Carefully weigh the costs and benefits of doing the work yourself versus hiring a professional. Consider your time, skills, and the complexity of the project.
• Follow Label Instructions: Always follow the herbicide label instructions meticulously. Using too much herbicide is not only wasteful but can also be harmful to the environment.
• Prevent Re-Infestation: Implement measures to prevent re-infestation, such as removing seed sources and monitoring the area regularly.
• Prioritize: If you have a limited budget, prioritize the areas that are most critical to protect, such as valuable trees or sensitive habitats.
• Document Everything: Keep track of your expenses and the time you spend on the project. This will help you refine your budget for future projects.
• Apply at the Right Time: Ensure you are applying herbicide at the right time of year for maximum effectiveness. This will reduce the need for repeat applications.
• Calibrate Your Sprayer: Properly calibrate your sprayer to ensure you’re applying the correct amount of herbicide. This will save you money and reduce the risk of over-application.

Industry Benchmarks and Statistical Data

While specific data on bittersweet removal costs is limited, here are some relevant industry benchmarks and statistical data points that can help you contextualize your project costs:

• Average Cost of Herbicide Application: According to the National Association of Landscape Professionals, the average cost of herbicide application for weed control ranges from $75 to $200 per acre. However, this is a broad estimate and doesn’t specifically address bittersweet removal.
• Average Hourly Rate for Landscaping Labor: The average hourly rate for landscaping labor in the United States ranges from $25 to $50, depending on location and experience.
• Timber Prices: Understanding timber prices in your region can help you assess the potential economic impact of bittersweet infestations on your timber resources. You can find timber price data from state forestry agencies and industry associations. I’ve seen first-hand how bittersweet can significantly devalue timber by causing tree mortality and reducing growth rates.
• Firewood Prices: If you’re harvesting firewood from trees killed by bittersweet, understanding local firewood prices can help you determine the potential value of the wood. The average price per cord of firewood in the United States ranges from $150 to $400, depending on the wood species, location, and demand.

Source: These numbers are compiled from various sources, including the National Association of Landscape Professionals, the U.S. Bureau of Labor Statistics, state forestry agencies, and firewood market reports. Always verify with local sources for the most up-to-date and accurate information.

Calculating Volume of Logs and Estimating Drying Time

Understanding how to calculate the volume of logs and estimate drying time is essential if you’re harvesting timber or firewood from trees affected by bittersweet.

• Calculating Log Volume (Board Feet): The most common method for calculating the volume of logs in board feet is the Doyle Log Scale. The formula is:

  Board Feet = (D – 4)² * L / 16

  Where:

  • D = Diameter of the log in inches (measured at the small end)
  • L = Length of the log in feet

  For example, a log that is 12 inches in diameter and 10 feet long would have a volume of:

  Board Feet = (12 – 4)² * 10 / 16 = 40 board feet

• Calculating Firewood Volume (Cords): A cord of firewood is a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long, for a total volume of 128 cubic feet. To estimate the number of cords in a pile of firewood, measure the height, width, and length of the pile in feet and divide by 128.

• Estimating Drying Time: The drying time for firewood depends on several factors, including the wood species, the size of the pieces, the climate, and how the wood is stacked. As a general rule, firewood should be dried for at least six months, and preferably a year, before burning. You can use a moisture meter to check the moisture content of the wood. Firewood is typically considered dry when the moisture content is below 20%. The initial moisture content varies drastically by species; some species of pine and poplar can have initial moisture content of 150% or higher.

  A rough estimate for drying time can be calculated using the following formula:

  Drying Time (months) = K * (Initial Moisture Content – Target Moisture Content)

  Where:

  • K = A constant that depends on the climate and stacking method (typically ranges from 0.05 to 0.1)
  • Initial Moisture Content = The moisture content of the wood when it is freshly cut
  • Target Moisture Content = The desired moisture content for burning (typically 20%)

  For example, if you’re drying oak firewood in a relatively dry climate and using a well-ventilated stacking method, you might use a K value of 0.05. If the initial moisture content of the oak is 60%, the estimated drying time would be:

  Drying Time (months) = 0.05 * (60 – 20) = 2 months (This is a very rough estimate, and actual drying time may vary significantly).

Case Studies: Budgeting for Bittersweet Removal

To illustrate the practical application of these cost and budgeting principles, let’s consider two case studies:

Case Study 1: Small-Scale Homeowner Project

• Scenario: A homeowner has a small infestation of bittersweet on a few trees in their backyard. The infestation covers approximately 500 square feet. They want to remove the bittersweet themselves using the cut-stump method.
• Budget:
  • Herbicide: $15
  • Fuel: $10
  • PPE: $5
  • Total: $30
• Timeline: The homeowner estimates that it will take them one weekend to complete the project.
• Challenges: The homeowner has limited experience with herbicide application and needs to be careful to avoid harming desirable plants.

Case Study 2: Large-Scale Land Management Project

• Scenario: A land manager needs to control a large infestation of bittersweet on a 50-acre property. The infestation is severe, covering a significant portion of the property and threatening valuable timber resources. They plan to use an integrated approach, combining cut-stump, basal bark, and foliar application methods.
• Budget:
  • Herbicide: $5,000
  • Penetrating Oil: $1,000
  • Equipment Rental: $500
  • Labor: $10,000
  • Total: $16,500
• Timeline: The land manager estimates that it will take a crew of four people two weeks to complete the initial treatment. Follow-up treatments will be required for several years.
• Challenges: The land manager needs to manage a large crew, coordinate the application of multiple herbicides, and minimize the impact on non-target plants. They also need to develop a long-term management plan to prevent re-infestation.
