Mint is one of those herbs you just can’t have too much of—whether it’s for your tea, sauces, mojitos, or freshening up your kitchen. But what if we told you that you could grow all the mint you need in nothing more than an old plastic bottle? Yep, it’s not only possible—it’s surprisingly easy! Let’s dive into this budget-friendly, space-saving gardening trick that turns trash into treasure.
Why Grow Mint in a Plastic Bottle?
Growing mint in a plastic bottle isn’t just a fun DIY project—it’s practical. Here’s why it works so well:
-
✅ Space-saver – Perfect for balconies, windowsills, and small patios
-
✅ Eco-friendly – Repurposes plastic bottles you’d otherwise toss
-
✅ Water-efficient – Bottles retain moisture longer
-
✅ Control freak’s dream – Keeps aggressive mint roots contained
So if you’ve struggled with mint taking over your garden beds or don’t have space for traditional pots, this method is for you.
What You’ll Need
Before we get started, gather these simple supplies:
-
1 empty 2-liter plastic bottle (clear is best)
-
A sharp knife or scissors
-
Potting mix (well-draining)
-
A few mint cuttings or a small mint plant
-
A nail or screwdriver for making holes
-
Optional: string or wire for hanging, a funnel for easy filling
Step-by-Step: How to Grow Mint in a Plastic Bottle
1. Cut the Bottle
Start by slicing the bottle in half—just below the label. You’ll use the bottom half as the planter and the top half as a mini greenhouse, or you can use the top half upside-down as a funnel if you prefer.
💡 Tip: Don’t throw away the top part—you’ll use it later!
2. Add Drainage Holes
Using a nail or screwdriver, poke 4–6 small holes in the bottom for drainage. Mint loves moist soil, but soggy roots? Not so much.
3. Fill with Soil
Fill the bottom half of the bottle with well-draining potting mix. Leave about an inch at the top so water doesn’t spill over.
🌿 Want a bonus boost? Mix in a bit of compost or slow-release fertilizer.
4. Plant the Mint
If you’ve got a mint cutting, just poke a finger-deep hole and place the stem in. If using a starter plant, gently tuck it in and firm the soil around the base.
Mint roots quickly—within a week or two, it’ll be well on its way.
5. Water and Cover
Give it a good drink of water. Now, place the top half of the bottle (cap off) over the plant to act as a humidity dome. This helps young cuttings root faster.
Once your mint is established (after about 2 weeks), you can remove the dome or keep it on during chilly nights.
6. Place in a Sunny Spot
Mint thrives in bright, indirect light. A windowsill, balcony railing, or sunny corner works great. Avoid scorching afternoon sun if you’re in a hot climate—it might dry out too fast.
Care Tips for Bottle-Grown Mint
-
💧 Water regularly – When the top inch of soil feels dry, give it a drink. Don’t let it dry out completely.
-
✂️ Harvest often – Snipping leaves encourages bushier growth. Pick from the top, and it’ll keep growing sideways.
-
🪴 Repot if needed – If roots start to circle the bottle, it may be time to upgrade to a bigger container.
Bonus: Vertical Mint Garden Wall
Want to go all-in? Stack multiple bottles horizontally with holes cut along the sides and grow several mint plants in one vertical setup. Hang it on a wall or balcony railing—instant herb wall!
Final Thoughts
Who knew something as simple as a plastic bottle could grow something as useful as fresh mint? With just a few cuts, some soil, and a bit of sunlight, you’ll have a thriving mint plant without spending a dime on fancy pots or garden beds.
So next time you finish a soda or bottle of water—don’t toss it. Grow something delicious instead!
