Since many lime seeds are obtained from purchased fruit, they’re most likely hybrids. Therefore, planting lime seeds from these fruits often will not produce identical limes. Polyembryonic seeds, or true seeds, will generally produce identical plants, however. These can normally be purchased from reputable nurseries specializing in citrus trees.
First you need to know:
Likewise, you can put seeds in a plastic baggie along with some moist soil. Regardless of the method you choose, keep the seeds moist (not soggy) and place them in a warm, sunny location. Germination usually occurs within a couple of weeks. Once seedlings have reached about 6 inches tall, they can be gently lifted and placed in individual pots.
Sterilize the soil. Fill a disposable aluminum pan with the potting soil and cover with foil. Place it in a preheated oven at 180 degrees F. Insert a meat thermometer through the foil and into the soil. When it reaches 180 degrees F, begin timing and remove after 30 minutes. Do not leave it in the oven for a longer period. Heat enough soil to fill the number of 3-inch pots you will be using.
Plant the seeds in the peat pot filled with sterilized and cooled soil. Simply push the seeds into the soil until they are covered.
Keep the peat pots in a dimly lit room.
Water the soil so that it is continually moist, but not wet.
Move the growing lime trees to a room with plenty of sunshine or good fluorescent lighting, after the first leaves appear.
Keep the seedling in the peat pot when transplanting to a larger pot or planting outside. Plant outside the following spring, or keep as a houseplant.
