Growing an orchid from seed is a delicate and rewarding process that allows you to propagate new orchid plants. Orchid seeds are extremely tiny, with over 500,000 seeds fitting on an aspirin tablet. This makes sourcing and handling the seeds a challenging first step. However, with proper sterile technique, nutrient agar medium, and adequate sunlight, you can successfully germinate orchid seeds at home.
Getting Started with Orchid Seed Germination
Here are the basic supplies you’ll need to get started growing an orchid from seed:
-
Orchid seed pods – Harvest unripe pods from a blooming orchid plant or purchase pods from a reputable supplier.
-
Sterile containers – Small jars, flasks, and vials to store seeds.
-
Distilled water – For rinsing and preparing nutrient agar medium
-
Bleach, alcohol, peroxide – For sterilizing all equipment.
-
Nutrient agar medium – Provides nutrients for seed germination. Can be purchased or homemade.
-
Tweezers, scalpel, gloves – For sterile seed handling.
-
Plastic bags – To create a humid environment for germination.
-
Bright, filtered light – Orchid seeds need 12+ hours of brightness to germinate.
Step-by-Step Guide to Germinating Orchid Seeds
Follow these steps for the best chances of successfully growing an orchid from seed:
-
Harvest and sterilize seeds – Carefully open seed pods and collect seeds using sterilized tools. Soak seeds in diluted bleach to kill bacteria. Rinse thoroughly.
-
Prepare nutrient agar – Mix agar powder with hot distilled water per instructions. Pour into sterilized flasks. Let cool and harden.
-
Create sterile workspace – Select an indoor area to work. Sterilize all work surfaces with diluted bleach.
-
Sow seeds – Use sterilized tweezers to place seeds onto the nutrient agar surface. Gently push seeds into agar.
-
Seal and label containers – Cap flasks or jars tightly. Label with orchid species and date.
-
Allow germination – Place containers in bright, indirect light and stable room temperature. Germination takes days to months depending on species.
-
Allow seedlings to grow – Once germinated, orchid seedlings need to grow large enough for transplantation. This takes 4-8 weeks typically.
-
Transplant seedlings – Carefully transplant each seedling into an individual container with fresh nutrient agar.
-
Pot young plants – When roots fill the container, transplant into orchid potting mix in small pots. Acclimate to lower humidity.
-
Grow to maturity – It may take several years for an orchid grown from seed to mature and produce flowers. Be patient!
Tips for Successful Germination
Here are some key tips to help your orchid seeds successfully sprout and grow:
-
Maintain sterility at all stages – Use sterilized tools and bleach solutions when handling seeds and making agar.
-
Give adequate air circulation – Orchid seeds need airflow to prevent mold and bacteria growth.
-
Provide very bright, indirect light – 12-14 hours of daily illumination from a sunny window is ideal.
-
Keep stable warm temperatures – 22-27°C (72-80°F) is optimal. Avoid cold shocks.
-
Use purified water – Distilled or rain water is best. Tap water may prevent germination.
-
Practice excellent hygiene – Working in a dust-free space with clean hands and tools is critical.
-
Check seeds often – Monitor for contamination and transfer sprouts to fresh agar as needed.
-
Be extremely patient – Orchid seeds can take weeks or months to germinate. Don’t give up too soon!
Caring for Young Orchid Plants
Once your orchid seeds have sprouted, you’ll need to continue providing careful care as the seedlings grow:
-
Keep ambient humidity high – Seedlings need 65%+ humidity. Lower gradually as plants mature.
-
Water minimally – Use a spray bottle to provide moisture. Avoid oversaturating growing medium.
-
Give diluted fertilizer – Apply 1/4 strength orchid fertilizer once seedlings are established.
-
Repot as needed – Transfer seedlings to larger containers as they become rootbound.
-
Watch for pests and disease – Isolate any infected plants immediately to prevent spreading.
-
Acclimate before transplanting – Gradually adjust seedlings to lower humidity and more air flow.
-
Be ready to wait – It can take 3+ years for an orchid grown from seed to bloom for the first time.
Troubleshooting Germination Issues
Here are some common problems you may encounter and how to address them:
-
Mold growth – Increase air circulation and sterilize containers with bleach. Discard affected seeds/seedlings.
-
Slow or no germination – Ensure seeds haven’t dried out. Try sowing fresh seeds. Verify temperatures and light levels are ideal.
-
Seeds rotting – Use purified water and sterilized tools and containers. Avoid overwatering.
-
Leaves yellowing or wilting – Usually indicates a bacterial or fungal infection. Isolate plants and treat with fungicides if condition spreads.
-
Root or stem rot – Caused by overwatering or unsuitable growing medium. Allow plants to dry out more between waterings. Repot in fresh mix.
-
Pest infestations – Isolate and discard any infected plants. Sterilize all growing areas and tools. Use horticultural oils or insecticidal soap sparingly.
Wrapping Up
Growing an orchid from tiny seed to mature blooming plant is a long yet gratifying process. Success requires careful sterile technique, lots of patience, and ideal growing conditions. But the chance to propagate your own unique orchid varieties makes it well worth the effort. With persistence and proper care, you can add to your orchid collection by raising these exotic beauties from seed.
Start Potting Your Orchid Plant
When your seedlings grow, you have to deflask and pot the plant. Start by watering the plant to make the roots wet and loosen the medium. This is a good process for deflating sympodial and monopodial orchids.
Find a clean pot with many holes at the bottom, and fill up the pot with coarse fir bark to about two inches (5.08cm) from the top. Add redwood shavings, horn meal, and dolomitic limestone.
In a cooking pot, heat some water to 96°F (35.6°C). Submerge the orchid containers to soften the agar for between 30 minutes to one hour. Gently pull out the seedling, taking special care not to damage the roots. Wash the orchids in tepid water to remove any remaining agar.
Plant your seedlings two inches (5.08cm) apart inside the pot. Find a small tray and put in some small pebbles. Pour some water inside the tray, then place your pot on top of the rocks. The water will evaporate slowly, adding some humidity to the plant’s immediate environment.
Place the tray with the pot in a warm sunny spot. Slightly spray the orchid with water several times a day. As your orchids grow, practice division and transplant your orchids to bigger pots as required.
Knowing the type of orchid you have and whether it’s monopodial or sympodial is important. Sympodial orchids grow horizontally, while monopodial orchids grow vertically. Division is an asexual method of propagating your orchids.
With division, instead of growing the orchid from the seed, you will be multiplying the mother plant. Division is the process of splitting the mother orchid into two or more actively growing plants. The baby plant is sometimes referred to as a Keiki and is an exact clone of the mother plant.
Division is often done when the orchid is ready for repotting. The orchid has probably outgrown its pot, or the plant’s center seems to be dying out.
To divide a sympodial orchid, use a sterile scalpel to slice through the rhizome. Ensure you’ve left at least a few leafy growths on each of the divided sections. At this point, you may also remove any disheveled pseudobulbs and damaged roots. Once you have separated the sections, pot them each in their pot.
The division of monopodial often involves cutting off the top of the plant. As monopodial becomes older, the bottom becomes leafless while the top loses some of its beauty. If you cut off the top, make your cut right below a node on the stem. Check that there’s a well-developed root system just above your cut. Then, plant the upper part in a new medium.
Another division method for monopodial is to cut the stem directly below the air layer. This method is used when the aerial roots seem to be rotting. Before you cut, you must first go through the process of strengthening your roots, as detailed above.
Always remember to keep detailed records of all propagations. Repot your orchid in a bigger size than its former pot. Time the division, so it happens just before the next growing season. Never use tools on your orchids unless you have first sterilized the tools and your gloves.
Deflask the Orchid Seedlings
Eventually, the young orchids will have to move to pots filled with coarse tree bark and other materials. Only move the orchids when the roots are visible, and the plant is big enough to handle. Wash off the agar, then swirl the roots in distilled water to remove any sugar residues. Organic residues can attract bacteria and molds.
To protect your precious orchids from drying up, follow these steps:
- Transfer them to a plastic box first.
- Add some sphagnum moss or paper to the box and spray some water on the sphagnum moss, paper, and orchid.
- Put the box in a shaded area, preferably outdoors.
