There's a balcony in the Plateau — you've probably walked past it without even realizing. Colander stuffed with basil. Cherry tomatoes climbing a weathered wooden ladder. An old enamel pot overflowing with nasturtiums catching the morning light. No garden centre receipt in sight.
Urban sustainable gardening doesn't require a budget, a backyard, or a trip to a big-box store. It requires curiosity, a little patience, and the right trouvaille. Montreal's balconies, rooftops, back courtyards, and fire escape landings are built for this. And the objects that make the most interesting gardens? They're already out there, waiting for a second act.
This guide walks you through exactly how to build a thriving container garden using pre-loved vintage objects — from what to look for, to how to prep each piece, to what to plant where. Better for the planet, easier on your wallet, and infinitely more interesting than a row of identical plastic pots.
Step 1: Start With a Vision (and a Sketch)
Before you set foot in a thrift store, spend fifteen minutes with your space. Seriously — this one step saves you from hauling home a beautiful ceramic crock that gets zero sun and a tomato plant that quietly gives up by mid-June.
Walk your balcony, rooftop, or courtyard and ask a few simple questions. Which direction does it face? A south-facing Plateau balcony gets six-plus hours of direct sun and can grow tomatoes, peppers, and herbs with abandon. A north-facing Mile End landing might average two or three hours — perfect for lettuces, mint, and ferns, less ideal for anything that loves heat.
Next, think about what you actually want from your garden. Herbs for cooking? A pollinator patch for bees? Cherry tomatoes for summer salads? Flowers to brighten the space? You don't have to choose just one — but knowing your goals shapes what containers you're hunting for and what plants you'll eventually bring home.
Sketch a loose layout. Nothing fancy — just a rough map of your space showing where tall things can go (back corners, against walls), where trailing plants will cascade beautifully (railing edges, elevated spots), and where compact herbs can cluster on a table or step. If you're on a balcony, make a note of weight: soil is heavy, and multiple large containers add up. Lightweight potting mix and smaller containers toward the outer edges keep things structurally sound.
Step 2: Know What to Hunt For at the Thrift Store
This is where the real fun begins. Once you know your space and your goals, you can walk into any thrift store with purpose — and a completely different eye for what's sitting on those shelves.
Containers That Work
Enamel pots and colanders are the ultimate vintage garden containers. The colander's holes handle drainage for you. The enamel pot's depth is perfect for herbs or a single tomato plant. Both are nearly indestructible outdoors and look spectacular with a little rust patina.
Wooden crates and drawers are endlessly versatile — line them with burlap or coco coir and you have a raised bed on a balcony. Wine crates, vegetable crates, old dresser drawers: they all work. The rougher, the better.
Ceramic crocks and terracotta retain moisture beautifully, making them ideal for plants that like consistent watering. Old crocks, mismatched mugs, chipped casserole dishes — if it holds soil and has a drainage hole (or can have one added), it belongs in a garden.
Galvanized watering cans and vintage tins add immediate charm and handle outdoor conditions well. Look for ones with interesting shapes or faded labels — they become statement pieces even before you plant anything in them.
Wicker baskets work surprisingly well when lined with coco coir, which keeps soil in while letting moisture breathe. They're especially beautiful for trailing strawberries or herbs.
Garden Structures
Don't stop at containers. Vintage objects make extraordinary garden structures too.
An old wooden ladder leaned against a wall becomes an instant vertical garden — perfect for climbing beans, peas, or small cucumbers. Wrought iron chairs and stools make beautiful planter bases when you remove the seat and drop in a planted basket. Vintage shutters mounted horizontally can serve as a trellis. Even an old picture frame filled with wire mesh and small pots becomes a vertical herb wall.
What to Inspect Before You Buy
Metal pieces: Surface rust is completely fine — it's aesthetic, not structural. Deep pitting that compromises the integrity of the base is worth skipping. A quick pass with a wire brush handles the rest.
Wooden pieces: Press gently on corners and joins to check for soft spots that indicate rot. Light weathering is fine and adds character; structural softness means the wood won't last a season outdoors.
Painted pieces: Very old painted items (pre-1970s) can contain lead paint. If you're planning to grow edible plants and you're not sure of the piece's age, pick up a lead paint test kit at any hardware store — they're inexpensive and take two minutes.
What to Skip
Anything with chemical residue labels (old pesticide containers, herbicide sprayers) stays on the shelf. Foam or soft plastic degrades quickly outdoors, breaks down in UV light, and isn't worth the effort.
Montreal tip: EcoDepot's Lachine and Plateau locations rotate enamel cookware, wooden crates, vintage tins, ceramic crocks, and garden furniture regularly — and the hunt is always fresh.
Step 3: Prep Your Vintage Containers
Found your pieces? Great. A little prep work now means a thriving garden all season — and containers that last for years, not just one summer.
Metal Pieces (Enamel Pots, Tins, Colanders, Watering Cans)
Start with a thorough wash — soap, water, a good scrub, rinse well. Let dry completely before planting.
If your piece doesn't have drainage holes, create them: a hammer and a large nail punched through the bottom three to five times does the job in under a minute. Drainage is non-negotiable. Waterlogged roots kill plants faster than drought.
Light surface rust on galvanized pieces is fine to leave. A quick pass with a wire brush knocks off anything loose. Avoid using pieces with peeling enamel on the interior surface in contact with edible plants — chipped exterior enamel on the outside is fine; interior peeling near soil and roots is where you want caution.
Wooden Pieces (Crates, Drawers, Old Chairs)
Sand any rough or splintering edges. Then seal the wood with linseed oil or a natural beeswax finish — this extends outdoor life significantly and slows moisture damage without adding chemicals.
Line the interior with burlap or coco coir liner before adding soil. This keeps soil in, lets drainage happen, and slows the wood's contact with wet soil (which accelerates rot). Elevate the piece off the floor or ground surface using small feet or bricks — even a centimetre of airflow underneath makes a meaningful difference to longevity.
Ceramic and Terracotta
Check for deep cracks — hairline cracks are purely cosmetic and fine for planting. A crack that runs through the full thickness is a water damage risk and will likely split further over a Montreal winter.
Soak new terracotta in water for thirty minutes before planting. Terracotta is porous and will wick moisture from soil and roots if it goes in dry — a good soak saturates the clay first, so your plants get the water instead.
Safety note: If a piece has chipped or flaking paint and was made before the 1970s, test for lead paint before using it for edible plants. Test kits are available at Canadian Tire, Rona, and most hardware stores.
Step 4: Choose the Right Soil and Drainage Setup
Good soil is the single biggest factor in container garden success. It's also where most beginners make their first mistake — and it's an easy one to avoid.
Never use garden soil in containers. Garden soil compacts in pots, cutting off the air and drainage roots need. Use a quality potting mix instead — it's lighter, airier, and formulated to stay loose in a container environment.
If you're on a balcony, weight matters. Lightweight potting mixes (look for ones with perlite or coir listed in the ingredients) reduce structural load. Spread larger containers along the inner wall rather than the outer railing edge.
For most containers, add 10–20% perlite to your potting mix. Perlite is the tiny white granules you'll find at any garden centre — it dramatically improves drainage in deep containers and prevents the heavy, waterlogged conditions that rot roots.
Layer your containers from bottom to top:
-
A layer of gravel, broken pottery shards, or coarse sand (2–3 cm) at the base for drainage
-
Potting mix to about 3 cm below the rim
-
Your plants
-
A thin top layer of mulch or compost to retain moisture and slow weeds
Step 5: Match Plants to Containers (and to Montreal's Season)
This is where your garden actually comes to life. The good news: there's almost no combination of vintage container and plant that doesn't work, as long as you match depth and sun correctly.
Small Containers — Tins, Mugs, Colanders
These are perfect for herbs: basil, thyme, chives, parsley, and cilantro all thrive in small containers with good drainage and at least four hours of sun. Mint works brilliantly in a contained pot — in fact, a pot is the ideal home for mint, which spreads aggressively if given ground. Succulents and sedums are nearly indestructible choices for hot, south-facing spots with irregular watering.
Medium Containers — Enamel Pots, Wooden Crates, Ceramic Crocks
Here's where vegetables come in. Cherry tomatoes, peppers, lettuces, spinach, and arugula all do beautifully in medium-depth containers. Look for "patio" or "container" on seed packets — these are varieties specifically bred to stay compact and productive in smaller spaces.
Nasturtiums are the secret weapon of the container garden: they grow fast, bloom in orange and gold all summer, require virtually zero attention, and the flowers are edible. They look extraordinary cascading over the edge of a wooden crate.
Large and Structural Pieces — Old Drawers, Chairs, Galvanized Tubs
Go ambitious here. Strawberries trail beautifully over the edges of large containers. Bush beans, kale, zucchini (choose a compact variety), and even dwarf pumpkins can all work in a generous-sized piece.
This is also where pollinator mixes shine. Echinacea, lavender, black-eyed Susans, and cosmos fill a large vintage drawer or galvanized tub with colour all season — and Montreal's urban bees and butterflies will find you within days.
Vertical Structures — Ladders, Shutters, Frames
Climbing beans and peas are made for ladders and trellises. Small cucumbers too, with a bit of guiding at the start. For a softer look, trailing herbs like creeping thyme and oregano are beautiful cascading down from elevated spots.
Montreal Timing
Montreal's last frost date sits around mid-May — typically the long weekend is the traditional signal for Montrealers to start planting outdoors. Hardy lettuces, spinach, chives, and pansies can go out earlier, in late April, under a light row cover or fleece. Start seeds indoors in late March if you want a head start; pick up seedlings from any marché or garden centre from late May onward.
Step 6: Maintain Your Vintage Garden Through the Season
A container garden in a Montreal summer is lively, productive — and thirsty. Here's how to keep it thriving from May to the first frost in October.
Watering is the most important daily habit. Containers dry out significantly faster than in-ground beds, especially terracotta and wood, which lose moisture through their walls. In July and August heat, check containers daily — sometimes twice daily for small terracotta pots in full sun. A simple finger test works perfectly: stick your finger 2 cm into the soil; if it's dry at that depth, water thoroughly until it flows from the drainage holes.
Feeding matters in containers because nutrients wash out with every watering. A liquid seaweed or fish emulsion fertilizer every two to three weeks keeps container plants productive through the whole season. Organic options are available at most garden centres and are safe for edible plants.
Deadheading — removing spent flowers — encourages continuous blooming in flowering plants. Five minutes once a week keeps nasturtiums, echinacea, and cosmos producing all summer.
End of season: Wooden and wicker containers should come inside or move to a sheltered spot before the first hard frost — Montreal winters are not gentle, and the freeze-thaw cycle cracks wood quickly. Metal and ceramic containers can often stay outside, though emptying and inverting them prevents water from pooling and freezing inside. Your soil can be composted or refreshed with new compost for next spring.
Bonus: 5 Vintage-to-Garden Ideas to Try This Weekend
Not sure where to start? These five projects each take under an hour from thrift find to planted garden.
1. The Colander Herb Patch Drainage is built right in. Fill with potting mix, plant three or four herbs, hang from a balcony railing hook — done. Basil, thyme, and chives make a beautiful combination.
2. The Ladder Trellis Lean a vintage wooden ladder against a wall or fence. Plant climbing beans or peas at the base, guide the first tendrils onto the rungs, and let them do the rest. By midsummer you'll have a vertical wall of green.
3. The Enamel Pot Tomato Tower A deep enamel pot, one cherry tomato plant (Tumbling Tom or Balcony varieties are ideal for Montreal), and a single bamboo stake. Water daily, feed every two weeks, and you'll be picking tomatoes by late July.
4. The Crate Salad Garden Line a wooden wine crate with burlap, fill with potting mix, and plant a mix of lettuces, arugula, and spinach. Direct-sow seeds or use seedlings — either works. Cut leaves as you need them, and the plants keep producing.
5. The Chair Planter Find a vintage wooden or wrought iron chair. Remove the seat or drop a planted basket into the frame. Add trailing strawberries or a mix of herbs and nasturtiums. Instant garden focal point, zero construction required.
Your Next Garden Starts With a Find
Urban sustainable gardening isn't about having the right setup — it's about seeing the right potential. That enamel colander on the shelf isn't kitchenware. It's a herb garden waiting to happen. That wooden crate in the corner? A balcony salad bed. That wrought iron chair? One basket and a handful of strawberry runners away from being the best thing on your patio.
Every vintage find has a second act. Your urban garden might be its best one yet.
