How to Grow Orchids From Seeds Orchids, perennial members of the Orchidaceae family and genus Orchis that grow in USDA cold hardiness zones 6 through 11, are typically cultivated as indoor plants. Orchid propagation, like other plants, can be done through division, cuttings or from seed. Growing orchids from seed, which results in unpredictable hybrid plants, is typically done in a laboratory, but can be done at home with careful attention to sterilization. Of the two types of seed growth, open air propagation and asymbiotic in-vitro propagation, the second is simpler, as it avoids the need for mycorrhizal fungal exposure. Prepare Agar Medium 1 Collect unripe seed capsules from an orchid plant that have not split yet, but still have thick walls. 2 Mix equal parts orchid gelling medium with distilled water in a cooking pot. Stir the mixture and heat it over the stove to boiling. Keep stirring for two minutes. 3 Pour the mixture into the lidded glass containers, filling them to 20 percent. This is called flasking. Add the lids and cover them with aluminum foil. 4 Heat the containers, along with another lidded glass container, in the oven for 20 to 30 minutes to sterilize them. Let them stand for several days. Sterilize Seed Capsules 1 Fill a cooking pot with water and boil it to steaming. Place a small grill section on top of the pot, and use it as a work surface to keep equipment sterilized. 2 Put on a pair of rubber gloves and sterilize the grill surface and forceps with 70 percent ethanol. 3 Fill the empty lidded glass container with bleach. Add seed capsules to sterilize them for 15 minutes. 4 Transfer each seed capsule to the grill with the forceps, then sterilize them in the ethanol again. If the grill mesh is too large to hold the seeds, first lay down a piece of ethanol-soaked paper towel. 5 Sterilize the scalpel or sharp knife and open the seed capsules. Sterilize equipment between each capsule. Scrape out the seeds. 6 Open the orchid medium containers over the steam and transfer the seeds into the containers with the forceps. Replace the cap and aluminum foil, and place the containers in a window that receives indirect sunlight. Transplant Orchid Seedlings 1 Thin out the crowded seedlings between 30 and 60 days by transflasking. Remove each seedling from the original containers and put them into new ones, also filled with the agar medium. Once the seedlings outgrow the containers, transplant them into a planting pot. 2 Prepare a 5 inch planting pot by filling it with coarse fir bark, stopping 2 inches from the top. Fill the rest of the pot with a moist orchid compost mixture that includes seedling grade fir bark, redwood shavings, dolomitic limestone and hoof and horn meal. 3 Fill a cooking pot with water and heat it to 96 degrees Fahrenheit. Submerge the seedling containers in the water to soften the agar, and wait for 45 minutes. Bend a piece of wire into a loop and carefully pull the seedlings out of the containers with the loop. 4 Wash the seedlings in lukewarm water to remove any remaining agar, then plant them in the pot, 2 inches apart. Keep the pot in a warm, sunny spot and after the first week, mist the seedlings with water several times each day. 5 Transplant the orchids to separate pots once they outgrow the original pot.
