Mini Balcony Herb Garden

Three small pots of culinary herbs, with drainage and a tray, for a balcony that gets some sun. The layout uses pots about 14 cm across and 5 cm gaps, so the row is 52 cm. Measure your pots and change the row if they differ. Mint stays in its own pot because it spreads through a shared box.

Materials

  • Qty: 3

    Purpose: One plant each. The layout math uses 14 cm pots.

  • Qty: enough to fill the pots, stopping 2 cm below the rim

    Purpose: The growing medium. Not garden soil.

  • Qty: 3

    Purpose: The plants. Mint does not share a pot.

  • Qty: at least 52 Γ— 16 cm for 14 cm pots

    Purpose: Catches drainage. You empty it.

  • Qty: 3

    Purpose: So the mint pot stays identified

Tools

  • A nail or a drill, only if a pot has no drainage hole
  • A scoop or a cup
  • Watering container
  • Measuring tape

Steps

  1. Steps 1: Check the sun and the railing

    Stand where the pots will live. You want some direct sun, not a corner that stays dark all day. The pots go on the balcony floor or on a shelf inside the railing. They do not go on the rail. A 52 cm row needs a clear run of that length, plus room to water.

  2. Steps 2: Give every pot a way to drain

    Use 3 containers about 12–15 cm across. The layout below assumes 14 cm. If a pot has no hole, pierce 3 holes about 5 mm wide: one in the middle and one to each side. Do this over a bin. Skip any pot you cannot put a hole in.

  3. Steps 3: Fill with potting mix

    Cover each hole with a scrap of paper or a shard so mix does not pour out. Do not plug the hole with clay. Fill to about 2 cm below the rim. One pot is for mint alone. The other two can be basil, parsley, or another soft herb you cook with.

  4. Steps 4: Plant at the same depth

    Tip the seedling out, loosen a circling root with a finger, and set it so the stem sits at the depth it had in the nursery pot. Fill around it and firm gently. Keep the 2 cm gap at the rim so water has a moment to soak. Label the mint. Mint in the basil pot will take the basil over.

  5. Steps 5: Space the row and set the tray

    Leave 5 cm of air between rims. 3 pots of 14 cm and two gaps of 5 cm need 52 cm (14 + 5 + 14 + 5 + 14). The tray is at least 52 Γ— 16 cm. If your pots are wider, add the extra to 52 cm before you pick a shelf.

  6. Steps 6: Water, then empty the tray

    Water each pot until a little runs from the holes. Wait about 10 minutes and pour the tray out. The tray is a catch, not a reservoir. After that, water when the top of the mix is dry to your first knuckle, and stop when it drips.

  7. Steps 7: The first week

    Keep new seedlings out of a wind tunnel if the balcony has one. Pinch a leggy basil tip above a pair of leaves. Do not take more than a sprig in the first week. Keep the 5 cm gap so leaves are not pressed wet against glass or a wall.

Final result

3 drained pots in a 52 cm row with 5 cm gaps, mint on its own, in a tray you empty after watering. The mix stops about 2 cm below the rim. The row is inside the balcony, not on the rail.

Safety

  • Keep pots inside the railing. A pot on the rail can fall onto someone below.
  • Pierce holes downward into a bin, not toward your hand.
  • Wash your hands after handling mix and seedlings.
  • Rinse what you harvest. If you do not know what was sprayed on a seedling before you bought it, do not eat that plant.
  • This is a small container garden, not a structural planter. Do not load a weak shelf with wet pots.

Tips and common mistakes

  • Recalculate the row if your pots are not 14 cm. Keep the 5 cm gap.
  • Mint gets its own pot even when you only have two other herbs.
  • Common mistake: a sealed pot with gravel in the bottom. Gravel does not replace a hole.
  • Common mistake: leaving the tray full. Empty it after about 10 minutes.
  • A balcony with no direct sun will disappoint basil. Parsley takes less sun than basil, but a dark well is not a herb garden.
