Living in a small apartment or urban home doesn’t mean you have to give up on growing your own herbs, vegetables, or flowers. If you’ve run out of ground space, it’s time to start growing up — literally. A DIY vertical planter is the perfect solution for small-space gardeners who want to maximize their growing area without sacrificing style or functionality.
In this article, you’ll learn how to build a vertical planter step-by-step, where to place it, what plants grow best, and how to maintain it — even if you’re working with just a balcony or a blank wall.
Why Go Vertical?
Vertical gardening isn’t just a trend — it’s a smart way to:
- Grow more in less space
- Keep plants organized and accessible
- Add beauty to walls, fences, and balconies
- Improve airflow and reduce pests
- Reduce back strain from bending over garden beds
Whether you’re a renter, apartment dweller, or homeowner with limited space, vertical planters let you transform any sunny wall into a productive green space.
What You Can Grow in a Vertical Planter
Many compact and shallow-rooted plants thrive in vertical systems. These include:
Herbs
- Basil
- Mint
- Parsley
- Thyme
- Chives
- Cilantro
Leafy Greens
- Lettuce
- Spinach
- Arugula
- Kale (baby varieties)
- Swiss chard
Compact Vegetables
- Cherry tomatoes (with support)
- Peppers
- Radishes
- Green onions
Flowers
- Petunias
- Marigolds
- Pansies
- Nasturtiums
The key is choosing plants with shallow roots and avoiding deep-rooted vegetables like carrots or corn.
Supplies for a Simple DIY Vertical Planter
You don’t need advanced tools or expensive materials. Here’s what you’ll need for a basic wall-mounted or freestanding planter.
Materials:
- Wooden pallet (or cedar planks, if building from scratch)
- Landscape fabric or breathable weed barrier
- Staple gun and staples
- Hammer and nails (or screws and drill)
- Potting mix
- Plants or seeds
Optional:
- Hanging pots
- Zip ties
- Hooks or brackets (for mounting)
- Waterproof liner (for indoor use)
Step-by-Step: How to Build a DIY Vertical Planter
Step 1: Choose the Right Location
Pick a wall, fence, or balcony area that receives at least 4–6 hours of sunlight daily. Make sure the wall can support the weight of moist soil and plants.
Step 2: Prepare the Frame
If using a wooden pallet:
- Sand any rough edges
- Clean the surface if reclaimed
- Reinforce the bottom slats to form planting pockets
If building from planks:
- Create stacked planter boxes or shelves with 6–8 inch depth
Step 3: Line the Planter
Staple landscape fabric inside each planting pocket or shelf to hold the soil. Make sure it’s breathable and drains well.
For wall-mounted options, ensure the bottom has small holes or breathable fabric for drainage.
Step 4: Add Soil
Fill each pocket or container with lightweight potting mix. Avoid using garden soil — it’s too dense for vertical setups.
You can also mix in coco coir or compost for improved water retention and nutrients.
Step 5: Plant Your Greens
Add your selected herbs, greens, or flowers. Start with smaller transplants or seeds, spacing them to avoid crowding as they grow.
Water thoroughly after planting.
Step 6: Secure and Mount (if needed)
If you haven’t already, attach your planter to the wall using brackets or sturdy hooks. For freestanding models, make sure they’re balanced and stable.
Watering and Maintenance Tips
Vertical planters dry out faster than ground beds due to gravity and exposure. Keep these tips in mind:
- Water daily in hot weather, especially for top rows
- Use a watering can with a narrow spout to reach upper pockets
- Install a drip irrigation line for larger vertical gardens
- Add mulch or moss to the top of each pocket to reduce moisture loss
- Check for pests regularly — vertical gardens can attract aphids or mites if airflow is poor
Rotate plants occasionally to ensure even sun exposure if you’re using a movable setup.
Creative Ideas for Vertical Planters
Vertical gardening doesn’t have to be boring. Try these aesthetic and functional twists:
1. Shoe Organizer Planter
Hang a canvas shoe organizer on a fence or balcony railing. Fill each pocket with soil and add herbs or lettuce.
2. Stacked Crate Garden
Stack wooden crates in a staircase pattern. Fill each level with different types of greens or flowers.
3. Hanging Bottle Planters
Cut plastic bottles horizontally, add drainage holes, and hang them in rows using twine or wire.
4. Wall Frame Garden
Build a picture frame with depth, line it with landscape fabric, and plant succulents or moss for an artistic, living wall.
Benefits of Vertical Gardening in Small Spaces
- Maximizes limited space in apartments or patios
- Reduces weed problems — no soil-level weeds to pull
- Improves air circulation around plants
- Adds visual height and greenery to dull walls
- Keeps plants within reach, making maintenance easy
- Great for renters — easy to disassemble and take with you
It’s also a fantastic option for seniors or anyone with limited mobility.
Common Mistakes to Avoid
- Overcrowding: Gives plants no room to spread and can lead to disease
- Poor drainage: Causes root rot — always use breathable fabric or drainage holes
- Inadequate sun: Most herbs and vegetables need at least 4 hours of sunlight
- Heavy soil: Makes the planter too heavy and can compact over time
Start small and test different setups before scaling up.
Frequently Asked Questions
Q: Can I use my vertical planter indoors?
A: Yes, as long as it’s near a sunny window or under a grow light. Use a waterproof liner or tray to catch excess water.
Q: How often should I fertilize vertical planters?
A: Every 3–4 weeks with a diluted liquid fertilizer or compost tea. Vertical setups leach nutrients faster.
Q: What’s the best material for long-lasting planters?
A: Cedar wood, metal frames, or plastic stackers are durable and weather-resistant. Avoid untreated softwoods in humid climates.
Q: Can I grow root vegetables vertically?
A: Shallow-rooted crops like radishes or green onions are possible, but deep-rooted crops like carrots aren’t suitable.
Q: What should I do in winter?
A: Either disassemble and store the setup or plant winter greens like kale or spinach in frost-tolerant zones.
