Materials / Tools Needed
Here’s everything you’ll need to grow coriander in plastic bottles at home:
- Plastic bottles (1L or 2L) – Any used water or soda bottle will work.
- Coriander seeds (dhaniya dana) – Choose organic, unpolished seeds for better germination.
- Potting soil or garden soil mix – Light, well-draining, and rich in organic matter.
- Water spray bottle – To gently water without disturbing seeds.
- Sunny spot – Balcony or window with 4–5 hours of sunlight daily.
- Small tools – A knife or scissors for cutting bottles, a small trowel for mixing soil.
- Organic compost or vermicompost – To give your coriander a nutrient boost.
💡 Pro Tip: Mix 70% soil + 30% compost for the perfect coriander-growing blend.
Step-by-Step Instructions
Step 1: Prepare the Plastic Bottle
- Take a used 1L or 2L plastic bottle and cut it horizontally in half.
- Keep the bottom part for planting. You can also use the upper part by turning it upside down and adding a drainage hole.
- Make 3–4 small holes at the base for water drainage.
Tip: Without proper drainage, coriander roots rot easily. Always ensure that extra water can escape.
Step 2: Prepare the Soil Mix
- Combine your potting soil and compost in a 70:30 ratio.
- Mix in a handful of cocopeat (optional) to help retain moisture.
- Fill the bottle about 3/4 full with this mix, leaving a small gap at the top for watering.

Bonus Tip: Add a teaspoon of neem powder to prevent soil fungus and pests naturally.
Step 3: Prepare and Sow the Coriander Seeds
- Gently crush the coriander seeds between your palms or with a rolling pin. This helps them split and germinate faster.
- Sprinkle the seeds evenly on top of the soil.
- Cover lightly with a thin layer of soil (about 0.5 cm). Don’t bury them too deep — they need some light to sprout.
Tip: Use fresh seeds! Old coriander seeds often have low germination rates.
Step 4: Water Gently and Cover
- Use a spray bottle to mist the soil surface until evenly moist.
- Cover the bottle with a thin plastic sheet or a newspaper for 2–3 days to trap humidity.
- Once tiny green shoots appear, remove the cover and keep the bottle in a bright spot.

Avoid Overwatering: Coriander loves moist soil, not soggy mud. Water only when the topsoil feels dry.
Step 5: Sunlight & Care Routine
- Place your bottles in a sunny area like a balcony railing, windowsill, or terrace.
- Coriander needs 4–5 hours of sunlight daily for healthy growth.
- Rotate the bottle every few days so all sides get sunlight evenly.
Pro Tip: During very hot afternoons, shift bottles to partial shade to prevent leaf burn.
Step 6: Watering & Feeding
- Mist daily in the morning, or whenever the soil starts to dry.
- Every 10–12 days, feed with diluted organic liquid fertiliser or compost tea.
- Keep an eye on yellow leaves — it often means a lack of nutrients or too much water.
Quick Fix: Mix 1 spoon of compost in water, let it sit for 24 hours, and use it as a natural growth booster.
Step 7: Harvesting Your Fresh Coriander
- Within 20–25 days, you’ll see lush green leaves ready for harvest.
- Use scissors to snip the outer leaves, allowing the inner shoots to continue growing.
- Avoid pulling the entire plant if you want multiple harvests.
Tip: For continuous supply, sow a new batch every 10–15 days in another bottle.
Experts’ Tips & Tricks

Tip 3: Natural Pest Control
- Sprinkle neem powder or spray neem oil weekly to keep aphids and mites away.
