Yes, apartment dwellers lasagna gardening works great in pots and planters. You use the same layering system on your balcony or patio. The results are just as good once you get the setup right.
I tested this on my own third-floor balcony using a 30-gallon fabric grow bag. I layered in torn cardboard, dried leaves from the park, kitchen scraps, and coffee grounds from the cafe downstairs. Within four months that bag turned into rich soil that grew the best cherry tomatoes I have ever tasted.
A coworker of mine tried the same thing in two large plastic bins on her fire escape. She drilled holes in the bottom for drainage and filled them with layers just like a ground bed. Her herbs and lettuce grew fast and she saved a ton compared to buying potting soil.
The layering idea stays the same in containers, but the smaller volume changes a few things. Your layers break down faster because the container heats up more in the sun. You also need to check moisture more often since pots dry out much quicker than ground beds. Plan on watering your container lasagna bed every 2 to 3 days in warm weather.
The Brooklyn Botanic Garden uses a 4 by 8 foot (1.2 by 2.4 meter) raised bed as their standard model. You can scale that concept down for your balcony lasagna garden. A single 2 by 4 foot planter box gives you enough room for tomatoes, herbs, and salad greens. Even a large pot works if you keep it at least 18 inches (46 cm) deep so your layers have room to break down.
Weight matters a lot when you garden above ground level. A cubic foot of wet soil weighs about 80 pounds. Check your balcony's weight limit before you fill up large containers. Fabric grow bags weigh less than ceramic or wood planters. Spread your containers around the balcony instead of grouping them in one corner to spread the load.
Container lasagna gardening small space setups need materials you can find in the city. Save your kitchen scraps in a countertop bin. Grab cardboard boxes from local stores. Collect fallen leaves from parks or street trees in autumn. Coffee shops often give away used grounds for free if you ask. You can build a full container bed without buying a single thing.
If your balcony is too small or your building does not allow planters, look into community garden plots near you. Many city plots welcome the lasagna method since it builds soil without digging. Either way, your apartment address does not stop you from growing great food with this system.
