The construction of raised gardening beds using railroad ties has gained popularity among gardeners because these materials are both visually appealing and durable. Railroad ties, or railway ties as they are commonly known, have been used for a long time in the construction of railway tracks. However, their robust and rustic look has made them a desired choice for building raised garden beds. This article goes through the process of building, maintaining, and deriving the most benefits from a railroad tie-raised bed. It addresses the common questions concerning the construction process while providing helpful insights that can be incorporated into your gardening.
What is a Railroad Tie Raised Bed?
Gardening using railroad ties for elevation is called a Railroad Tie Raised Bed. These engineering timber beams, which were previously used in laying down railways, are stacked horizontally and vertically to form a box-like structure, which is then filled with garden soil. A primary benefit of utilizing these raised beds is improvement in soil drainage, prevention of soil compaction, and easier control over the growing environment. Their robust structure ensures they can withstand weathering and soil, making them useful in raised bed construction.
Key Features of Railroad Tie-Raised Beds
- Height: Raised beds have an elevation of approximately 6-12 inches. However, these beds can be higher or lower depending on the area and the plants growing within them.
- Durability: The wood used in railroad ties is treated with chemicals to enhance durability. As a result, they last longer outdoors; however, the leaching of chemicals into the soil is a concern.
- Dimensions: To customize the size of the raised bed, the number of railroad ties required to reach the desired height and length can be adjusted. Standard ties have a length of 8 feet, a width of 9 inches, and a thickness of 7 inches.
Advantages of a Railroad Tie Raised Bed
Longevity and Durability
Using railroad ties in the construction of raised beds has numerous advantages, one of the most important being durability. Railroad ties are made with pressure-treated wood, so they are designed to endure rough weather when coupled with a heavyweight. When well kept, railroad ties can last 20 or more years, which is a substantial amount of time for raised beds.
Enhanced Visual Characteristics
Railroad ties provide a rustic classic look that fits seamlessly into a variety of garden styles. The weathered rustic appeal of railroad ties helps add character and formality to parts of the garden, regardless of whether you are creating a formal vegetable garden or a casual flower bed. The natural color of the wood allows it to blend well with different plants, which makes it a more desirable material.
Soil Temperature Moderation
In areas with fluctuating temperatures, railroad ties can be helpful for controlling the temperature within the soil of raised beds. The wood’s high density makes it possible to retain heat during the colder months and warm the soil earlier in spring, thus allowing for lengthened growing seasons. This is especially helpful when growing a wide variety of plants with higher temperature demand like tomatoes and peppers.
Drainage Capabilities
Raised beds can be a great improvement in drainage since they now enable water to flow through the soil more freely. This is important in places where water stagnates, or the soil becomes too dense. As mentioned before, planting boxes made from railroad ties do not allow water to pool at the bottom, helping prevent root rot and enabling healthy plant growth.
Less Work Intensive
Mobility-challenged or people who have difficulty leaning over will find working with plants on the ground easier with raised beds. A bed made out of railroad ties will facilitate gardening by positioning the soil at an ergonomic height, thereby reducing the amount of kneeling and bending required.
How to Construct a Tie-Raised Bed: A Comprehensive Guide
Constructing a railroad tie-raised bed is easy when you have the appropriate tools and materials in hand. This guide provides detailed step-by-step instructions for making a raised bed with railroad ties.
Required Supplies
- Railroad Ties: 8-foot-long railroad ties are best for raised beds.
- Screws or Nails: Galvanized screws or nails are best as they are non-rusting and durable.
- Shovel: For leveling and digging ground.
- Level: To check if the bed is leveled evenly.
- Measuring Tape: To record the size of the raised bed.
- (Optional) Wood Sealant: To enhance the longevity of the railroad tie.
Procedures for Construction
- Pick the desired location: Choose areas that are flat and exposed to sunlight for about 6 hours daily.
- Ground preparation: Grab a shovel and begin to clear the designated site. Make sure that all grass, stems, and other forms of waste material within that zone are removed so that the bottom of the raised bed sits directly on the soil.
- Track Tie Arrangement: The initial layer of track ties can be set horizontally to act as the frame for the bed. Additional track ties can be placed vertically to give the bed additional height, but make sure the poles are positioned correctly.
- Affix the Poles: Each layer of the track tie can be held together with galvanized screws or drywall screws. Listed screws can be used but must be affixed after making a pilot hole, or else the wood will crack. To make the bed more stable, the ties must be placed at a right angle to the edges of the bed.
- Soil Mixture: After the frame is set, the rest of the bed can be filled with good-quality soil, farmyard compost, and other decaying materials. Additionally, the soil at the bottom layer must be able to drain properly.
- Irrigate and Fertilize: Before setting the crops, the bed should be watered thoroughly. This action encourages the soil to settle and permits better establishment for the future plants set.
Possible Disadvantages of Railroad
Tie Raised Beds Even though there are various reasons that favor setting raised beds with railroad ties, it is imperative to take a few of them into consideration before using them.
Issues in Chemistry
Wooden ties on the railroad are usually treated with oil of creosote or other chemicals to protect them from rotting or insects. Eventually, soil might become contaminated with chemicals, including some toxic substances like creosote, which makes it quite dangerous for plants and soil alike.
- Solution: Covering the inside of the planter with plastic material as a border is one of the most effective ways to solve the problem. Other alternatives include the use of newer, untreated creosote ties, untreated timber, or concrete blocks.
Comparison in Finances
In relation to other bed materials, wooden railroad ties should be classified as very costly materials, especially when a large number is needed for bigger garden beds. In some regions, railroad ties are sold for anywhere from $15 to $30 per tie, and prices change according to the vendor and area.
Environmental Impacts
The treatment of the ties entails some chemicals, which pose an environmental risk. In addition, railroad ties are not renewable, and their extraction and use may result in environmental damage over time. If sustainability is a core concern of your garden, look into alternatives such as recycled materials instead of ties.
Maintenance and Care for the Raised Bed with Railroad Ties
Like any structure, the raised bed with railroad ties requires care in order to sustain its form and health for many years. In order to do this, you will need to complete some maintenance tasks regularly. Follow these simple guidelines to maintain the bed:
Seal the Wood
Consider using a wood sealant or preservative to protect the railroad ties from weathering. It can be exposed to the rain or the sun, as well as rot, and still allow the ties to remain strong over the years.
Check for Sturdy Construction
Always look at your raised bed from time to time to ensure that the railroad ties have not come loose and that the bed is still level. As time goes by, the ties may settle, and the structure of the bed will change. Increase the tightness on screws and re-stabilize the bed as needed.
Removing Ties
Failure to take action on a railroad tie that has rotted or is under structural stress is a bad practice that can prove to be detrimental to the integrity of the bed.
Other Factors To Consider When Constructing Railroad Tie-Raised Beds
There are noticeable benefits to constructing a railroad-tie raised bed garden. Still, other important factors should be considered in order to sustain success over the long term and avoid undesirable outcomes. These factors include examining the quality of the soil, where the bed will be placed, the sources of material for the bed, and how these factors will affect your garden objectives.
Soil Quality and Fertilization Methods
Using a raised bed garden comes with many advantages, one of which is the control you get over the quality of the soil. It is important to understand that even when the soil within the raised bed is good, it still must be managed in terms of fertility. Use the following recommendations to make sure your soil is in an optimal state for plant growth:
- Compost: Organic matter, compost in this instance, can be added to a raised bed as a means to improve aesthetics, moisture retention, nutrient availability, as well as soil structure. Aside from actively improving the soil’s ability to retain nutrients, compost also supplies beneficial microorganisms that enhance the health of the plants.
- Soil Testing: Have regular soil tests conducted so you remain updated on the pH, nutrients, and drainage levels of your bed soil. This way, you can make necessary changes to enhance growth.
- Fertilization: Use organic, slow-release fertilizers to refortify the nutrients in your raised bed over time. This will ensure that the plants receive the required nutrients without inflicting any damage to the surrounding ecosystem.
Placement and Spacing
The placement of your railroad tie raised bed is one of the most important aspects of promoting plant growth. Here are a few things to keep in mind when selecting an optimal site.
- Sunlight: Always make sure the chosen site has enough sunlight. Most vegetables and flowering plants require at least 6 hours of sunlight each day to thrive. If you plan on growing multiple crops, consider factoring in the different amounts of sunlight individual plants need.
- Accessibility: Consider how you will be able to reach the raised bed. Make sure there is ample space surrounding the bed to allow for movement, watering, and harvesting. Create pathways that allow movement to and from the bed, especially when using large ties or building multiple raised beds.
- Wind exposure: Don’t put raised beds in locations that are too windy. This can dry out the soil and kill the plants. If your region is particularly windy, constructing windbreaks around the garden may be beneficial.
Watering and Irrigation
The improvement in drainage that comes with the elevation of the garden beds made from railroad ties can, however, lead to elevated rates of desiccation relative to ground gardens. For this reason, frequent watering may be necessary. Here are some tips for efficient watering:
- Drip Irrigation: With the help of drip irrigation, water can be delivered directly to the foundation of individual plants, thereby decreasing water quantity and mitigating wet foliage on leaves, which can result in fungal infections.
- Mulching: The application of organic mulch, including straw, grass clippings, and wood chips, can lead to increased retention of soil moisture along with stable temperatures, particularly in hotter summer months.
- Watering Schedule: During the warmer months, make sure to keep track of the water provided to the raised bed. Make sure to water deeply and consistently while avoiding overwatering in order to prevent root rot.
Pest Control
Insect infestation presents another problem for gardening, which is also the case for gardening with railroad-tie raised beds. Fortunately, these beds can be designed in a way that will reduce some of the more severe pest issues. Still, there are a number of ways to manage pests that you can apply:
- Physical Barriers: To protect plants from flying pests such as aphids, moths, and beetles, row covers or netting can be very effective. Row covers, in particular, are great for protecting seedlings during the first part of their growth cycle.
- Natural Predators: Plant flowers such as marigolds, sunflowers, and lavender to attract useful insects that will eat harmful ones like ladybugs, predatory beetles, and lacewings.
- Insecticidal Soap: For some more stubborn pests, consider using organic insecticidal soap that will work against aphids, spider mites, and most other garden insects in a more environmentally friendly way.
Environmental Impact of Railroad Ties
Garden buildings made out of railroad ties can look great, but you still can’t forget about their environmental impact, especially with the chemicals that were used to treat and dispose of them.
Leaching of Chemicals and its Impact on Soil
Most normal railroad ties were soaked in preservatives (creosote), which renders them dangerous for human and plant use. When ties are subjected to moisture, creosote can leach into the soil. These chemicals, pollutants from a bygone epoch, pose a threat to surrounding plants and to the groundwater resource.
If you’re worried about the chemicals in railroad ties, here are some other tips:
- Plastic Cover: Similar to what was discussed previously, installing a raised bed cover made of plastic can prevent the leaching of creosote or any other chemicals.
- Use of Untreated Ties: Some gardeners have been using untreated railroad ties, which do not stand up as long as pressure-treated wood. Make sure you keep in mind that untreated wood does not have a long life expectancy like pressure-treated wood, so you should be ready to do some work.
Disposal Considerations for Old Railroad Ties
Currently, unused railroad ties present disposal issues because their disposal is complicated. Because of chemical treatment, creosote-treated ties are often considered hazardous waste, meaning they cannot be disposed of easily in a standard landfill. If you’re replacing an old railroad tie, make sure you do not simply discard them. Some local municipalities provide hazardous waste dumpsters or check with your waste management provider.
