Why so many people are planting in pots, windows, and rooftops
Imagine harvesting fresh basil from your window to season your lunch pasta without going to the market, without plastic packaging, without that wilted herb that lasted two days in the fridge drawer. For many people, this still seems like something only people with farms do. But the reality is different: urban farming has been growing in apartments, townhouses, terraces, and even schools throughout Brazil.
The term may sound technical, but the practice is simple. Cultivating food inside or around where you live, at any scale, is already urban farming. Whether it’s a five-pot herb garden on a window sill, a community garden in your neighborhood square, or a vertical garden in your hallway, it all counts. And the gains go beyond the food itself: savings at the market, reduced organic waste, better air quality inside your home, and a different relationship with what you eat.
By the end of reading this article, you’ll understand what urban farming really is, why it makes sense for the Brazilian context, and you’ll have a clear path to set up your first garden, even without space, soil, or experience.
What is urban farming and how it appears in Brazil
Urban farming is the production of food, medicinal plants, or seasonings in areas within or around cities. The Food and Agriculture Organization of the United Nations (FAO) recognizes the practice as a strategy for food security and urban sustainability, especially relevant in developing countries.
In Brazil, urban farming is not new. “Backyard gardens” have always been part of popular culture, especially in the North and Northeast regions. What has changed in recent years is the scale and profile of who practices it: young people in apartments in large cities, residential condominiums with collective gardens, restaurants growing their own ingredients on rooftops. Embrapa, which has been monitoring the topic for decades, has already identified urban farming as a relevant component for both food and well-being of Brazilian urban populations.
Municipal programs in cities like São Paulo, Belo Horizonte, and Curitiba include community gardens in parks and schools. Belo Horizonte, for example, has a long tradition in the field, having incorporated urban farming into food security policies since the 1990s. This shows that growing food in the city is not a fad: it’s a concrete response to real challenges.
Why farming in the city makes a difference beyond the plate
Growing cherry tomatoes in a pot won’t save the planet alone. But when the practice multiplies, the effects add up in concrete ways.
From an environmental perspective, urban farming reduces the so-called “food footprint”: food travels less distance from producer to you, which decreases transportation emissions and the amount of packaging discarded. The FAO points out that food waste and transportation account for a significant portion of global food system emissions. Each local market or home garden is a step against this.
From a household perspective, the garden is one of the smartest ways to deal with organic waste. If you’ve ever tried composting at home, you know it goes hand in hand with gardening: compost feeds the soil, and soil produces food. This logic closes a cycle that reduces what goes to the trash. In Brazil, according to Abrelpe data, organic matter represents more than half of household waste sent to landfills. Composting and planting, even on a small scale, is a direct response to this problem.
There is also the mental health benefit, which more and more studies investigate. Having contact with plants, caring for something alive, observing growth, are experiences with proven effects in stress reduction. And financially: fresh herbs like basil, cilantro, chives, and mint have disproportionately high prices in the market, given the quantities that come in packaging. Growing at home is, literally, money saved.
How to set up your first urban garden: step by step
You don’t need soil, a garden, or special skills to start. What you need is a window with a few hours of sun per day and the willingness to try.
Basic materials:
- Pots or containers with drainage holes (can be cut PET bottles, wooden boxes, or ceramic pots)
- Substrate specific for vegetables (sold in any gardening store, between R$ 15 and R$ 30 per bag)
- Seeds or seedlings (seedlings are easier for beginners)
- A spray bottle or small watering can
Time to start: one afternoon. Planting itself takes about 30 minutes.
Step by step:
- Choose a location with at least four hours of direct sun per day. Windows facing north or east are best in Brazil.
- Select easy plants to begin with: chives, basil, mint, lettuce, or cilantro. They grow fast and don’t require much space.
- Prepare the pots: place a layer of small stones or ceramic shards at the bottom to help with drainage, then fill with substrate.
- Plant the seedlings or seeds according to package instructions. Don’t bury too deep; most herbs need little depth.
- Water with moderation: the most common mistake for beginners is watering too much. The substrate should be moist, never waterlogged.
- Observe daily. Plants give clear signals: yellow leaves may indicate too much water; very dry soil and wilted leaves ask for more watering.
- Harvest regularly. In herbs, harvesting encourages growth. Don’t wait for the plant to get huge to use it.
Common mistakes for beginners and how to avoid them
The biggest enemy of a beginner’s garden is not lack of space or insufficient sun. It’s too much enthusiasm at first and abandonment after the first difficulty.
Overwatering is mistake number one. Most herbs and vegetables die more from too much water than too little. Before watering, stick your finger in the substrate: if it’s still moist, wait another day.
Another frequent slip is choosing the wrong plants for your environment. Cilantro, beloved in the Northeast, doesn’t like intense heat and will wilt under the strong sun on a São Paulo balcony in summer. Chives, on the other hand, handle much more temperature variation. Research before planting.
Many people also underestimate the importance of substrate. Using regular garden soil in a pot is a recipe for trouble: it compacts, drains poorly, and can bring pests. The specific substrate for vegetables, available in gardening stores and even some markets, makes a real difference.
Finally, forget the idea that you need to solve everything at once. Start with two or three pots, learn the rhythm of the plants, and expand when you feel comfortable.
Options for those living in apartments without a balcony
Lack of outdoor space is not an excuse to not have a garden. There are smart solutions for small spaces.
- Vertical herb garden on interior wall: kits of modular pots fixed on the wall near the window work well for herbs and lettuce.
- Countertop garden: a tray with four or five small pots on the kitchen window sill already produces enough herbs for daily use.
- PET bottle garden: two-liter bottles cut in half, with drainage holes in the cap, are functional and free containers.
- Community gardens in your neighborhood: many municipalities maintain public growing spaces. It’s worth researching at your subprefecture or neighborhood association.
- Condominium beds: proposing a collective garden in your condominium is easier than it seems. A corner of common area with a few large pots and a simple agreement on sharing care duties is enough.

Real results: what to expect in the first few months
Chives start to grow noticeably one to two weeks after planting. Basil, under good sun conditions, is ready for partial harvesting in about three to four weeks. Lettuce, in mild climates, can be harvested in six to eight weeks.
Financially, the initial investment in pots, substrate, and seedlings rarely exceeds R$ 80 to R$ 100. Considering that a bunch of cilantro or a pot of fresh basil at the supermarket costs between R$ 3 and R$ 8, depending on the city, the account closes within a few months. And the quality of fresh produce, harvested on the spot, is incomparable to what comes in plastic from another city.
From the waste perspective, if you incorporate composting along with the garden, the amount of organic material going into the trash bag drops noticeably. And this, in turn, helps reduce pressure on Brazilian landfills, which, according to Abrelpe, already operate under great stress in much of the country.
Frequently asked questions about urban farming
Do I need soil to set up an urban garden?
No. Commercial substrate for vegetables replaces garden soil with advantages: it drains better, has less risk of pests, and is lighter. You don’t need a yard or soil bed to get started.
Can I grow vegetables beyond herbs in an apartment?
Yes, with adjustments. Cherry tomatoes, peppers, bell peppers, and even cucumbers grow in larger pots as long as there’s enough sun. For this, use pots of at least 10 to 15 liters and substrate enriched with compost or organic fertilizer.
How much time per day do I need to dedicate to the garden?
On average, five to ten minutes a day are enough to water and observe the plants. The most intensive work happens in the initial planting and occasional fertilizing, every three or four weeks. It’s much less labor-intensive than it seems.
Does the garden attract insects and pests indoors?
Pests can appear, but in indoor gardens they’re rare if the substrate is adequate and ventilation is good. The most common insects are aphids and fungus gnats, easily controlled with natural solutions like garlic spray or simply reducing watering. The risk is low and manageable.
Take the first step today, even if it’s just one pot
You don’t need an elaborate project, specialized courses, or generous space to start. A pot with chives on your kitchen window is already the beginning of something different in your relationship with food and the environment.
Get a container you would have thrown away, buy a bag of substrate the next time you pass a plant store, and plant a seedling of chives. Observe for two weeks. It’s likely that when you harvest your first fresh sprouts, you’ll want to expand.
Urban farming is one of the few sustainable practices that returns something immediate and concrete: food, savings, satisfaction. That’s what keeps it growing, window by window, pot by pot, throughout Brazil.
