With six citrus seeds your odds should be almost 100 percent that at least 4 of the seeds will germinate, if they are fresh seeds. Never let citrus seed dry out. The ideal temperature for germinating citrus seed is 86F (30C). I plant all my citrus seed in a mixture of 50 percent peat moss and 50 percent perlite. Maintain a moist germinating medium, and a temperature of 86F (30C) and your seed should germinate in 21 to 30 days. Actually, citrus are VERY EASY to germinate. With six seeds, almost any thing you plant them in should at least give you 50 percent success. - Millet
