Orchids are among the most breathtaking houseplants, admired for their vibrant flowers and graceful structure. But what if you could grow an endless supply of orchids from just one plant—without spending another cent at the garden center?
That’s exactly what many home gardeners are doing using an unexpected helper: a humble potato.
In this guide, you’ll learn how to propagate orchids naturally using a potato and garlic. It’s a little-known trick passed down by experienced gardeners and gaining popularity for its simplicity, cost-effectiveness, and amazing results.

Let’s get started on multiplying your orchids—naturally and endlessly.
Step-by-Step Guide: How to Propagate Orchids Using a Potato
This process uses everyday ingredients and materials, and it’s beginner-friendly. Follow each step carefully to give your orchid cuttings the best chance of rooting.
- Choose a healthy orchid cutting
Select an orchid that has flowered at least once and has firm, green stems. Avoid using any part of the plant that appears dry, brown, or mushy. - Disinfect your tools
Use rubbing alcohol or hot water to disinfect pruning shears or scissors. This helps prevent introducing fungi or bacteria to your new cutting. - Cut the stem properly
Snip a piece of orchid stem that includes at least one node or bud. Make the cut perpendicular, not angled, to increase surface area and stability. - Prepare the potato-garlic nutrient soak
In a small bowl, combine:- One piece of potato with sprouts (peeled or unpeeled)
- One garlic clove, finely chopped
- 1/4 cup of water
- Let it macerate in darkness
Cover the bowl and store it in a cool, dark spot (like a cupboard) for 5–7 days. This will draw out the nutrients and create a root-promoting liquid. - Strain the mixture
After a week, strain the mixture using a fine sieve or cheesecloth. Discard the solids and keep the liquid—this is your orchid nutrient soak. - Sterilize the orchid cutting
Dip the cut end of the orchid stem in a diluted hydrogen peroxide solution or dab with alcohol. This step prevents infections. - Soak the cutting in the potato-garlic solution
Place the cut end into the liquid soak and let it sit for 20–30 minutes to absorb beneficial compounds. - Plant in well-draining substrate
Use orchid bark or a loose, airy mix. Avoid compacted soil. Insert the cutting so that the treated end is in contact with the growing medium. - Maintain optimal conditions
Place the pot in a warm, humid location with indirect light. A bathroom or kitchen corner works perfectly. - Mist daily and avoid overwatering
Spray the air around the plant with water once or twice a day, but don’t saturate the soil. Orchids hate soggy roots. - Be patient and observe growth
Roots can begin forming in 2–6 weeks depending on temperature, humidity, and orchid species.

Common Mistakes and How to Avoid Them
Using an unhealthy orchid cutting
Make sure the parent plant is well-maintained. Weak or stressed orchids don’t root well.
Not disinfecting tools or cuttings
Skipping this step invites bacteria and fungal infections that can kill your new plant before it roots.
Soaking the cutting too long
More is not better. Over-soaking can soften tissues and cause rot.
Planting in poor soil
Orchids need loose, breathable growing mediums like bark or sphagnum moss. Avoid dense soil that retains too much moisture.
Neglecting humidity
Orchids thrive in moist air. If your home is dry, use a humidity tray or group plants together to create a microclimate.
Placing in direct sunlight
Indirect light is best. Direct sun can scorch your delicate cutting.
Benefits of Propagating Orchids with a Potato
Eco-friendly and zero waste
This method uses leftover potato parts and a single garlic clove—no chemical rooting agents needed.
Inexpensive
Forget store-bought orchid propagation kits. Everything you need is likely already in your kitchen.
Natural rooting hormones
Potatoes contain natural sugars and enzymes that encourage root development. Garlic adds antimicrobial properties that reduce infection risk.
Beginner-friendly
Even first-time gardeners can follow this step-by-step technique and see results.
Repeatable process
Once you succeed, you can repeat the process every season with new cuttings.
Seasonal and Regional Tips
Tropical and humid regions
Propagation is faster. Still, ensure the area is well-ventilated to prevent mold growth.
Dry climates or winter seasons
Use humidity trays or place a damp cloth near the orchid to maintain moisture levels. Avoid placing near heaters.
Hot summer temperatures
Shorten the maceration period to 3–5 days, as fermentation accelerates in heat.
Cold environments
Keep the maceration bowl above 18°C and use a heating mat under the pot if necessary to stimulate rooting.
Frequently Asked Questions
How do you propagate orchids with a potato?
Cut a healthy stem from a flowering orchid. Soak the cut end in a potato-garlic liquid for 30 minutes, then plant it in well-draining substrate under humid conditions.
Why use garlic and potato?
Potatoes provide carbohydrates and nutrients that help root growth. Garlic has antibacterial properties that prevent rot and infection.
Does this method work on all orchids?
It’s most effective on orchids with pseudobulbs, like Dendrobium or Cattleya. Success may vary with Phalaenopsis and other species.
How long does it take for roots to grow?
Anywhere from 2 to 6 weeks, depending on the orchid type and environmental conditions.
Can I reuse the potato mixture?
No. The mixture loses potency after maceration and may harbor bacteria. Always prepare a fresh soak.
How often should I water the new cutting?
Mist regularly but only water when the medium is nearly dry. Too much moisture leads to rot.
What if my cutting doesn’t root?
Try adjusting humidity, light levels, or check for rot. Not every cutting takes root, so try with several stems for better chances.
