Every kitchen produces a steady supply of empty food tins — baked beans, tomatoes, coconut milk — and most of them go straight into recycling without a second thought. With a coat of paint, a few drainage holes, and some potting soil, those same tins become charming planters that look right at home on a windowsill, a patio table, or a kitchen herb shelf. This guide covers everything from safe preparation to planting and displaying your finished tin can garden.

What You Will Need
- Empty food tins in assorted sizes — rinsed and label-free
- A hammer and a large nail (for drainage holes)
- Chalk paint, spray paint, or acrylic paint suitable for metal
- Primer spray (metal-specific, optional but recommended for longevity)
- Clear outdoor varnish or Mod Podge for sealing
- Potting compost appropriate to what you are planting
- Small stones or gravel for drainage layer
- Herb seedlings, succulents, or annual flower plugs
- Washi tape or stencils for decorative patterns
Project Info
- Difficulty: Very Easy — great for children too
- Time: 30–45 minutes per tin (plus drying time)
- Cost: Near zero — tins are free and paint is the only real expense
Step 1: Prepare the Tins
Remove any labels by soaking in hot, soapy water and peeling or scrubbing off. Sand the outside of each tin lightly with fine-grit sandpaper — this gives the paint something to grip. Wipe clean with a damp cloth, then dry thoroughly. Check the rim carefully for any sharp edges left by the tin opener; if present, use pliers to press them flat or file them smooth. Safety first — especially if children will be handling the finished planters.
Step 2: Add Drainage Holes
Place the tin upside down on a scrap of wood. Using a hammer and a large nail, punch three to five holes through the base of each tin. Space them evenly. Drainage holes are essential for plants — without them, roots sit in waterlogged soil and quickly rot. For purely decorative use (with artificial plants or as desk organisers), you can skip this step.
Step 3: Paint and Decorate
Apply a coat of metal primer spray if you have it, and allow to dry for 20 minutes. Then paint with chalk paint or spray paint in your chosen colour. Two thin coats give better coverage than one thick coat, and chalk paint in particular dries quickly between coats — usually 15–20 minutes. Once the base colour is dry, add decorative details: use washi tape strips as a stripe pattern, cut simple shapes from masking tape as a stencil, or paint freehand dots, stripes, or botanical motifs with a small brush. A collection of tins painted in coordinating colours — terracotta, sage green, cream, and warm white — looks especially striking grouped together. For help planning a themed set across different sizes, use the Craft Project Planner to note your colour combinations.
Step 4: Seal the Paint
Once decoration is complete and fully dry, seal the outside of each tin with a coat of clear outdoor varnish or Mod Podge. This protects the paint from moisture, condensation, and the inevitable drips that come with watering plants. For tins that will live outdoors, choose a specifically weather-resistant clear coat and apply two coats for maximum protection.
Step 5: Plant Up Your Tins
Add a 1–2 cm layer of small pebbles or gravel at the base of each tin to aid drainage above the nail holes. Fill to about two-thirds with potting compost appropriate to your chosen plants — a herb-specific compost for basil, mint, parsley, and chives; a succulent and cactus mix for low-maintenance succulents; standard multi-purpose compost for annual flowers. Plant your seedlings, press the soil firmly around the roots, and water gently until water drains from the holes.
Best Plants for Tin Can Planters
Herbs are the most popular choice: basil, mint, thyme, rosemary, chives, and parsley all thrive in small containers on a sunny windowsill. Succulents and cacti are ideal for forgetful waterers — they need minimal attention and look wonderful in groups of mismatched painted tins. For outdoor pots, trailing lobelia, compact marigolds, and violas add seasonal colour and are readily available as plug plants. Avoid large-rooted plants like tomatoes or courgettes — the tin volume is simply too small for their root systems.
Display Ideas
Line three or four painted herb tins along a kitchen windowsill for a functional, decorative herb garden within arm’s reach of the hob. For a vertical display, attach tins to a painted wooden pallet or a piece of driftwood using strong wire looped through two nail holes on the back — this creates a hanging planter wall perfect for a balcony or fence. Mix tin sizes: a large catering tin (from a restaurant-size chopped tomato can) makes a dramatic statement planter, while small sardine or paste tins are charming for individual succulent offsets. For more ideas on decorating with plants and crafts, see our Decoupage Flower Pots guide — the techniques complement each other beautifully.
Caring for Your Tin Planters
Metal tins will eventually rust if exposed to constant moisture, especially outdoors. The varnish seal slows this process significantly, but for long-term outdoor use, consider lining the inside of the tin with a piece of plastic bag (with drainage holes punched through to match the tin holes) before adding compost — this keeps moisture from the metal walls. Check for rust each season and touch up the paint and varnish as needed. Indoors, place tins on a saucer to catch drainage water and wipe dry after watering.
Tin can planters are one of the most accessible recycled crafts there is — free materials, minimal tools, and a result that is both beautiful and functional. Explore more upcycling and zero-waste craft ideas throughout our Recycled Crafts category.
