Building a rain gutter vertical garden is a great way to add some greenery to your outdoor space while also collecting and utilizing rainwater. You'll need to start by selecting a suitable location for your gutter garden, taking into account the amount of sunlight it will receive and the proximity to a water source.

To determine the right gutter size, consider the number of plants you want to include and the amount of water they'll need. A standard 6-inch gutter is a good starting point, but you may need to adjust based on your specific needs.

Choose a trellis or other support system to provide a structure for your plants to climb. This will help keep your gutter garden stable and make it easier to maintain.

Materials and Tools

For a rain gutter vertical garden, you'll need the right materials and tools. You can use pressure-treated lumber, like 2-inch x 4-inch x 8-foot boards, which is a good option for outdoor projects.

Lumber can be either pressure-treated or untreated, but if it's not treated, you'll need to treat it or paint it to protect it from the weather. Vinyl gutters, on the other hand, are usually sold in 10-foot lengths, so you'll need to buy the right number to match your project's needs.

Here are some of the materials you'll need:

  • Pressure-treated lumber (2-inch x 4-inch x 8-foot boards)
  • Vinyl gutters (10-foot lengths)
  • Gutter caps
  • Exterior screws
  • Wood dowel pins
  • L-shaped steel corner braces
  • Landscape fabric
  • Raised bed garden soil

As for tools, you'll need a saw, a drill/driver, and some basic hardware like wire staples or wire cutters.

Tools Used

To build a strong foundation, you'll need the right tools for the job. A tape measure is essential for taking precise measurements of materials and spaces.

A level is crucial for ensuring surfaces are perfectly horizontal or vertical. This prevents costly mistakes down the line.

A hammer is a versatile tool that's used for tapping pieces into place and breaking apart objects. Its versatility makes it a must-have in any workshop or construction site.

A drill is necessary for making precise holes in various materials. This is especially important when working with drywall or wood.

A saw is used for cutting through materials like wood or metal. The type of saw you choose will depend on the material you're working with.

A square is used to ensure corners are square and angles are accurate. This is critical when building anything from a simple bookshelf to a complex piece of furniture.

Supplies

If you're planning to build a vertical planter or a gutter garden, you'll need the right supplies.

Pressure-treated lumber is a popular choice for outdoor projects, and it's often left unpainted to withstand the weather. You'll need 2x4s or 2x6s for the frame, depending on your design.

For gutters, vinyl gutters are usually sold in 10-foot lengths. You'll need at least 4 lengths to cut 7 solid 4-foot lengths. Make sure to check the gutter profile for the correct end caps.

Here's a list of common gutter supplies:

  • Vinyl gutters (10-foot lengths)
  • Gutter caps (ensure they match your gutter profile)
  • End caps
  • Gutter attachment brackets
  • Flap hinges
  • Construction screws
  • Wire staples

Don't forget to choose the right screws for attaching the gutter to the fence. Some projects may require additional materials like glue, painter's tape, or shallow root plants.

If you're using a PVC rain gutter, you'll need 3-4 10-foot lengths, depending on your design. Always check the length of the gutter you need before making a purchase.

Preparation

Before you start building your rain gutter vertical garden, it's essential to prepare your gutters properly. Determine how long to cut your gutters, leaving 1 inch shorter than the 1"x4" boards you cut.

To ensure a clean and even finish, clean your gutters if they're dirty, washing them down with a hose and letting the water dry before painting. Prepare your space for spray painting by laying down a tarp to protect the area from overspray.

Cut your gutters 1½-inches shorter than the distance between the hypotenuse/cleats to leave room for the gutter caps. Place a gutter cap on the end of one gutter and use a rubber mallet to ensure it's well-seated.

Building the Planter

We're going to use a combination of rain gutter and wooden planks to create a sturdy planter for our vertical garden. This will provide a solid base for our plants to thrive.

The rain gutter will be cut to the desired length, taking into account the width of the wooden planks and the space needed for drainage. We'll also make sure to leave enough space for the plants' roots to grow.

The wooden planks will be attached to the rain gutter using screws, ensuring a secure and level surface for our plants.

Cut to Length

Cutting your gutter to the right length is crucial for a smooth installation process. Each gutter length should be 1-inch shorter than the 1"x4" boards you cut earlier.

The length of your gutter will depend on the space between the hypotenuse and cleats, leaving room for the gutter caps. You can use a rubber mallet to ensure the gutter cap is well-seated.

Cutting the gutter to size can be done at a home improvement store, like Home Depot, which may have a moulding cutting station. A fine-tooth hack saw might give a cleaner cut than a regular saw.

If you plan to cut your gutter at home, be sure to carefully measure and mark the center point to avoid uneven segments.

Attach Planters to Rails

Attach planters to rails is a crucial step in building your vertical garden planter. You'll need 7 pre-cut 1x4 rails and 7 rain gutter planters for this step.

Mark three or four drainage holes, spaced evenly along the inside center of the rain gutter, at least 9-inches from each end. This will ensure proper drainage for your plants.

To attach the planters to the rails, use ¾-inch exterior screws. You'll need about 5 screws per board. Make sure the planters fit easily over the dowel posts before proceeding.

Once the planters are attached, use a ½-inch drill bit to drill drainage holes through the gutter and board at the same time. This will create a smooth flow for water to drain out.

Here's a quick rundown of the materials you'll need for this step:

  • 7 - Pre-cut 1x4 rails
  • 7 - Rain gutter planters
  • ¾-inch Exterior Screws

Remember to check the mounted planters on the frame to ensure they fit easily over the dowel posts.

Finishing Touches

You can finish your rain gutter garden project over a weekend, as I did. This vertical garden project is a great way to make use of small spaces.

The gutters themselves are horizontal, but the overall garden is supported to grow on a vertical surface, making them also called vertical gardens.

Paint Segments, Ends, and Hangers

Painting your gutter segments, end caps, and hangers can be a straightforward process if you follow some simple guidelines.

First, always paint outdoors or in a well-ventilated area to avoid inhaling paint vapors. Wear a respirator appropriate for painting to ensure your safety.

To prepare your gutters, you may want to test your spray paint to make sure it adheres correctly to the plastic material. If needed, lightly sand the plastic with a fine grit sandpaper, such as 220 grit.

Shake the spray can vigorously for 1 to 2 minutes before use, as indicated on the can. Hold the can 10-16 inches away from the gutter surface and apply a thin coat of paint using an even side-to-side motion.

Applying 3 coats of paint to the gutters, end caps, and hangers is a good rule of thumb. This allows for maximum paint adhesion and durability on plastic, which is achieved in 5-7 days.

Improved View

A much improved view can make all the difference in a room. I can attest to this, as I transformed my home office window view from a plain fence to a vibrant garden.

Planting a gutter garden was a game-changer for me, as it utilized the vertical space and turned my boring fence into a work of art. The gutters themselves are horizontal, but the garden is supported to grow on a vertical surface.

This type of garden is perfect for small spaces, as it makes the most of the available area. I was able to finish my vertical garden project over a weekend, which made it a great DIY option.

A gutter garden can be a great way to add some greenery to a room, and it's surprisingly easy to maintain. The end result is a beautiful and uplifting view that can brighten up even the most mundane space.

Adding Plants and Drainage

Adding plants to your rain gutter vertical garden can be a fun and rewarding experience. Succulents are a great choice because they're low maintenance and can thrive in shallow containers.

Select plants with shallow roots that prefer shallow containers, such as succulents or herbs. I personally chose succulents of various shapes and colors from Home Depot, Lowe's, and a local nursery.

A good planting mix can make all the difference. My local nursery recommended a Palm, Cactus & Citrus Planting Mix that also worked well with succulents.

Add Drainage Holes

Adding drainage holes to your planters is a crucial step to prevent waterlogged soil and root rot. To create drainage holes, you'll need to drill large holes in the bottom of the planter.

I recommend spacing these holes about every 8 inches down the length of the planter for optimal drainage. Using a larger drill bit will help make the process easier.

Remember to wear your safety glasses when drilling to protect your eyes from debris. This is a simple step that can make a big difference in the health of your plants.
