How do you grow mandarin trees from a seed?

To grow mandarin trees from seeds, start by removing seeds from a ripe mandarin and rinsing them to remove any pulp. Soak the seeds in water for 24 hours, then plant them in a pot filled with well-draining soil, about half an inch deep. Keep the soil moist and place the pot in a warm, sunny location. Germination can take several weeks; once seedlings grow a few inches tall, they can be transplanted into larger pots or outdoors in suitable climates.
