How to Grow Basil from Cuttings in Hanging Plastic Bottles

A Complete Step-by-Step Guide for Fresh Herbs at Your Fingertips

Basil is one of the most beloved herbs in kitchens worldwide — and for good reason. Its sweet, slightly peppery, and aromatic leaves add freshness to pasta, salads, pizzas, pestos, and even desserts. The good news? You don’t need a big garden or fancy equipment to grow it. In fact, you can start your own basil plants from simple cuttings, using nothing more than recycled plastic bottles as hanging planters.

This method is perfect for small spaces, balconies, sunny kitchens, or anyone looking for a fun and sustainable gardening project.

In this guide, you’ll learn:

• Why growing basil from cuttings is faster than starting from seeds

• How to prepare basil cuttings for rooting

• How to set up hanging plastic bottle planters

• The best care practices to ensure healthy, bushy basil

• Tips for harvesting to keep your plants producing longer

1. Why Basil from Cuttings?

Most people start basil from seeds, but growing from cuttings has some big advantages:

1. Speed – Seeds can take weeks to germinate and grow large enough for harvesting. A cutting can be ready for planting in about a week.

2. Exact Replication – If you already have a basil plant you love (sweet basil, Thai basil, lemon basil, etc.), a cutting will produce an identical plant.

3. Year-Round Growing – You can take cuttings from store-bought basil or a friend’s plant, and grow them indoors even in winter.

4. Sustainable – Instead of throwing away stems when cooking, you can propagate them.

2. Choosing and Preparing Basil Cuttings

Step 1: Selecting Healthy Stems

• Look for green, vibrant stems without spots, damage, or signs of disease.

• Avoid woody stems (from older plants) — choose softer, young growth for faster rooting.

• Cut a stem that’s 10–15 cm (4–6 inches) long.

Step 2: Making the Cut

• Use a sharp, clean pair of scissors or garden shears.

• Cut the stem just below a leaf node (the point where leaves grow from the stem). Roots will sprout from here.

Step 3: Leaf Preparation

• Remove the bottom 2–3 sets of leaves so they won’t rot in water or soil.

• Keep the top leaves intact — they help with photosynthesis during rooting.

3. Rooting Basil in Water

You’ll first root the cuttings in water before moving them to hanging bottles.

Step 1: Place in a Jar

• Fill a glass jar with clean, room-temperature water.

• Insert the basil cuttings so the nodes are submerged but leaves are above water.

Step 2: Find the Right Spot

• Place the jar in a bright location but out of direct harsh sunlight, which can stress the cuttings.

• A windowsill with filtered light works best.

Step 3: Change the Water

• Change the water every 1–2 days to prevent bacteria growth.

Step 4: Wait for Roots

• In 5–10 days, you should see fine white roots forming.

• Wait until the roots are at least 5 cm (2 inches) long before planting.

4. Preparing Hanging Plastic Bottle Planters

Now comes the fun, eco-friendly part — turning used plastic bottles into hanging basil planters.

Materials Needed

• 1–2 liter plastic bottles

• A sharp knife or scissors

• A nail or skewer (for drainage holes)

• Potting mix (light, well-draining)

• Rope, twine, or strong string

• Optional: small stones or gravel for drainage

Step 1: Cutting the Bottle

• Lay the bottle on its side.

• Cut a rectangle window in the middle of the bottle (about 10 cm long), leaving enough plastic at the bottom to hold soil.

• Alternatively, cut off the top third of the bottle and use the bottom as a hanging cup.

Step 2: Making Drainage Holes

• Use a heated nail or skewer to poke 4–5 holes at the bottom for drainage.

• This prevents waterlogging and root rot.

Step 3: Adding Hanging Support

• Poke two holes near the top on opposite sides.

• Thread rope or twine through and knot securely to make a handle for hanging.

Step 4: Preparing the Soil

• Use a mix of 2 parts potting soil, 1 part compost, and 1 part perlite or sand for good drainage.

• Optional: Add a layer of small stones at the bottom for extra drainage.

5. Transplanting Basil Cuttings into Bottles

Step 1: Planting

• Gently place the rooted basil cutting into the prepared soil.

• Position it upright, and cover the roots completely.

• Press the soil lightly to secure the plant without compacting it too much.

Step 2: Watering

• Water thoroughly until it drains from the holes.

• Keep the soil moist but never soggy.

6. Hanging and Positioning Your Basil

Basil needs 6–8 hours of bright light daily.

• Hang your bottles near a sunny kitchen window, balcony railing, or outside wall.

• If indoors and light is limited, use a small grow light for 12–14 hours a day.

7. Caring for Basil in Hanging Bottles

Watering

• Check soil moisture daily. Plastic bottles dry out faster due to airflow.

• Water when the top 2 cm (about 1 inch) of soil feels dry.

Feeding

• Every 2–3 weeks, feed with a diluted liquid fertilizer (like a seaweed or compost tea) to keep leaves lush.

Pinching for Bushiness

• Regularly pinch off the top set of leaves once the plant is about 15 cm tall.

• This encourages side shoots and prevents tall, spindly growth.

Preventing Flowering

• If you see flower buds, pinch them off immediately. Flowering changes the flavor and slows leaf production.

8. Common Problems and Solutions

Problem	Likely Cause	Solution
Leaves turning yellow	Overwatering or nutrient deficiency	Check drainage, reduce watering, add balanced fertilizer
Leaves wilting	Underwatering or root damage	Water more consistently; ensure roots aren’t crowded
Aphids or pests	Insects attracted to tender leaves	Spray with neem oil or mild soapy water

---

9. Harvesting Your Basil

• Start harvesting once the plant has at least 6–8 leaves.

• Always pick from the top down to encourage bushiness.

• Never remove more than one-third of the plant at once.

---

10. Perpetual Basil Supply Tip

Once your plants mature, you can take new cuttings from them and repeat the cycle in more bottles. That way, you’ll have basil year-round without ever buying seeds again.

11. Advantages of the Hanging Bottle Method

• Space-saving — Ideal for balconies, windows, and small apartments.

• Recycled materials — Reduces plastic waste.

• Portable — Easily move your plants to follow the sun or bring them indoors in cold weather.

• Beautiful vertical garden effect — A line of green hanging basil can also be decorative.

Final Thoughts

Growing basil from cuttings in hanging plastic bottles is not only budget-friendly and eco-conscious but also a deeply satisfying project. In just a few weeks, you can go from having a single stem to enjoying fresh, fragrant leaves for pasta, salads, soups, and sauces — all from your very own hanging herb garden.
