Growing mint in bottles also prevents it from overtaking other plants in your garden, as mint tends to be invasive when planted directly in the soil. With this method, you can place your mint anywhere — on a balcony, windowsill, porch, or even hanging vertically on a wall.
What You Need
To grow mint in plastic bottles, you’ll need just a few simple materials:
A large plastic bottle (1.5 to 2-liter size is ideal)
A sharp knife or scissors
Mint cuttings or seedlings
Good-quality potting mix
Water
Optional: charcoal or small pebbles for drainage
Step 1: Prepare the Plastic Bottle
Start by selecting a clean, empty plastic bottle. Cut the bottle in half or cut out a rectangular section along the side (leaving the rest of the bottle intact). The goal is to create an opening large enough for planting while retaining the rest of the bottle to hold soil and water.
Next, poke a few drainage holes in the bottom of the bottle to prevent waterlogging. If you’re placing the bottle indoors or on a shelf, you may want to add a shallow dish or tray underneath to catch excess water.
For a self-watering design, you can create a wicking system. Cut the bottle in two-thirds (top and bottom). Invert the top part (like a funnel) into the bottom. Thread a cotton rope or strip of cloth through the bottle cap hole to wick water from the bottom reservoir into the soil above.
