Outdoor wall-mounted planter boxes can add flowers, herbs, or greenery without taking up floor space. The right choice depends on where you plan to hang it, how much room your plants need, and whether you want a coco liner or a simple metal container. These four options range from compact sets to long, multi-box arrangements, with different mounting hardware and setup needs.

LaLaGreen 24-Inch Planters: A Simple Matching Pair
This two-pack gives you a pair of long, rectangular planters for a wall, fence, or window area. Each planter is 24 inches long and made from black carbon steel. The clean, dark finish can suit a modern outdoor space or provide a simple backdrop for colorful flowers and green foliage.
Screws and anchors are included for wall installation, which makes this a more straightforward choice than planters that require you to source your own mounting hardware. The listing also describes use on rails, railings, and fences, but check the mounting method and the fit of your intended surface before installing.
The pair format is useful when you want a balanced arrangement, such as one planter on either side of a doorway or two side by side along a wall. The listing highlights flowers, herbs, succulents, and artificial plants. Since the description does not specify a drainage design, consider how excess water will be managed before planting directly in the containers.
Compared with the coco-lined options here, these have a more defined rectangular shape and do not list a liner as included. They are a good fit if you want two matching metal planters and included wall fasteners, rather than a large set or a natural-fiber planting surface.
Pros:
- Two matching 24-inch planters in one set
- Screws and anchors are included for wall installation
- Black carbon steel design suits a range of planting styles
- Can be used for flowers, herbs, succulents, or artificial plants
Cons:
- The listing does not specify a drainage system or include a coco liner
- Check your wall or railing setup, since mounting needs can vary by surface
Verdict: Choose this pair if you want two matching, long metal planters and included wall hardware; consider a coco-lined model if that planting medium is important to you.
KIDYBELL 24-Inch Planter: Flexible Railing or Wall Setup
The KIDYBELL is a 24-inch metal planter with a coco liner, designed for a railing, balcony, deck, or wall. Its adjustable brackets are listed for railings from 3 to 6 inches wide. Zip ties are included for other railings and fences, and the planter can also be screwed directly to a wall or window sill.
The frame is described as hand-welded steel bars with a protective coating. The coco liner gives the planter a more natural look and is described as breathable, with water-holding and drainage benefits. As with any lined planter, keep in mind that the growing medium and the plants you choose will affect how often it needs watering.
This model stands out for its range of mounting options. It may suit you if you are deciding between hanging a planter from a railing and attaching one to a wall. Before ordering, measure the railing and check that the included bracket setup matches its shape and width. The product description does not list a pair or multi-pack, so it is a single-planter option.
Pros:
- Adjustable brackets are listed for railings 3 to 6 inches wide
- Zip ties are included for other railing and fence setups
- Can also be screwed to a wall or window sill
- Coco liner adds a natural-looking planting surface
Cons:
- Confirm the railing width and shape before choosing this mounting style
- Sold as one 24-inch planter rather than a matching multi-pack
Verdict: This is a practical choice if you want one coco-lined planter and value having several possible mounting methods.
Karlliu 14-Inch Planters: A Compact Four-Box Set
Karlliu’s set includes four 14-inch half-round planters with coco coir liners. Their smaller size can make it easier to create a repeated pattern across a wall, fence, or railing without using one long planter. The listing describes a carbon steel frame with a rust-resistant powder coating.
The coco liners are described as holding water while allowing drainage and airflow around plant roots. Wall anchors, screws, and zip ties are included, giving you options for flat surfaces as well as railings or fences. Check the surface and plan the spacing before mounting all four, especially if you want a neat, even display.
These are the most compact option in this comparison, so they may suit smaller plants or a decorative arrangement better than a wide, continuous planting bed. The listing does not specify the capacity of each planter, so consider the root space your chosen plants need. Compared with the larger LaLaGreen sets, this option prioritizes several smaller containers over long troughs.
Pros:
- Four planters make it easy to create a coordinated display
- Compact 14-inch half-round shape suits smaller spaces
- Coco coir liners are included
- Wall anchors, screws, and zip ties are included
Cons:
- Smaller planters may not offer enough room for larger plants
- Four separate boxes require careful spacing and mounting
Verdict: Choose the Karlliu set for a compact, multi-point display with coco liners and several mounting accessories.
LaLaGreen 36-Inch Planters: Long Boxes for Larger Displays
This four-pack includes 36-inch rectangular planters with coco coir liners. Their longer profile can help create a continuous-looking row of flowers, herbs, or other plants along a fence, porch, or wall. The listing describes a lightweight metal construction with a powder-coated finish and says the planters can be used indoors or outdoors.
These boxes do not include brackets. The listing suggests using household accessories such as screws, S-hooks, or zip ties, depending on the installation. That flexibility can be helpful, but it also means you need to plan the mounting method and obtain suitable hardware for your surface. Do not assume the supplied set is ready to attach to every wall or railing.
The coco liners are described as helping hold water while supporting drainage and airflow. The long format offers more room for an arrangement than the compact Karlliu boxes, but the product description does not provide capacity or weight limits. Plan for the weight of the planter, growing medium, and water when choosing where and how to mount it.
The supplied listing data marks this product unavailable, so confirm its current availability before planning a project around the set. If available, it is the most extensive option here by overall planter length, but it requires more thought about hardware than the LaLaGreen 24-inch pair or the KIDYBELL model.
Pros:
- Four long 36-inch planters suit broad planting displays
- Coco coir liners are included
- Listing describes use on walls, fences, railings, and porches
- Powder-coated metal frame is described for indoor and outdoor use
Cons:
- Brackets are not included, so mounting hardware must be planned separately
- The supplied listing data marks the product unavailable
Verdict: Consider this set for a long, coordinated planting run if it is available and you are prepared to choose and supply suitable mounting hardware.
How to Choose an Outdoor Wall-Mounted Planter Box
Measure the mounting area first
Measure the available wall, fence, or railing space before selecting a planter. Check both the length of the planter and how far it may extend from the mounting surface. For railing models, measure the railing width and compare it with the listed bracket range. A planter that fits the available space is easier to arrange and less likely to interfere with doors, windows, or walkways.
Match the mounting method to your surface
Planters may use screws and anchors, adjustable brackets, zip ties, or separate hooks. These methods are not interchangeable for every surface. Check what is included, what your mounting surface can support, and whether you need to buy additional hardware. For example, the KIDYBELL includes adjustable railing brackets, while the LaLaGreen 36-inch set does not include brackets.
Choose a size that fits your plants
Longer boxes can create a broad display, while smaller planters can be arranged in a pattern or used where space is limited. Consider the mature size and root needs of the plants you want to grow. The product descriptions do not provide full planting capacity for every model, so check the listing details and avoid choosing by length alone.
Decide whether you want a liner
A coco liner gives a planter a natural-looking interior and is included with the KIDYBELL, Karlliu, and LaLaGreen 36-inch sets. The LaLaGreen 24-inch pair does not list a liner as included. Liner material, growing medium, and watering habits all affect plant care, so think about how you plan to fill and maintain the boxes.
Consider water management and plant care
Outdoor planters are exposed to rain as well as routine watering. Check the product details for drainage information, and consider where water may run off after installation. The supplied descriptions do not confirm a drainage system for every model. Select plants suited to the location’s light and conditions, and make sure you can reach the planters for watering and upkeep.
Plan for the weight once planted
A planter’s load changes after you add growing medium and water. The product details do not provide weight limits for these options, so do not assume every wall or railing can safely support a filled box. Use a mounting method suited to your surface, follow the product instructions, and consider the total load before installation.
Think about the look and number of boxes
A pair of matching long planters can create a balanced arrangement, while a four-pack of smaller boxes gives you more flexibility in spacing. Multiple long boxes can cover a broader area but need enough mounting points and suitable support. Decide whether you want one continuous row, separate accents, or a coordinated set across several surfaces.
Frequently Asked Questions
Can these planter boxes be mounted on a wall and a railing?
Some can be used in more than one way, but the included hardware differs. The KIDYBELL includes adjustable brackets for specified railing widths, zip ties, and the option to screw it to a wall or sill. The LaLaGreen 24-inch set includes screws and anchors for wall installation and is also described for railings and fences. Check each product’s instructions and your surface before mounting.
Which option comes with coco liners?
The KIDYBELL 24-inch planter, Karlliu 14-inch set, and LaLaGreen 36-inch set list coco liners as included. The LaLaGreen 24-inch pair does not list a liner as part of the set.
Which planter set is best for a small space?
The Karlliu planters are 14 inches long and come in a set of four, so they may be easier to place in smaller sections than the 24- or 36-inch options. Measure your available space and consider whether four separate mounting points will work for your layout.
Do all of these planters include mounting hardware?
No. The LaLaGreen 24-inch pair lists screws and anchors, the KIDYBELL includes adjustable brackets and zip ties, and the Karlliu set includes wall anchors, screws, and zip ties. The LaLaGreen 36-inch set does not include brackets and may require separate mounting accessories.
Are the planters suitable for herbs?
The product descriptions mention herbs for the LaLaGreen 24-inch and 36-inch planters. Before planting, check that the planter’s size, light exposure, and water management suit the herbs you choose.
Do these planters have drainage holes?
The supplied product details do not confirm drainage holes for every model. Check the listing and product instructions before planting, and consider how water will drain or collect in your chosen setup.
Is the LaLaGreen 36-inch set available?
The supplied listing data marks it unavailable. Availability can change, so check the product page before deciding on this option.
Final Recommendation
For most shoppers who want a straightforward pair of wall planters, the LaLaGreen 24-inch set is a practical starting point because it includes screws and anchors. Choose the KIDYBELL if railing compatibility and a coco liner are priorities, or the Karlliu set if you prefer four smaller boxes for a compact display. The LaLaGreen 36-inch set offers the longest planting format, but it requires separate mounting hardware and is marked unavailable in the supplied listing data. Measure your space, verify the mounting setup, and choose the planter that best matches your plants and installation surface.
