Soaking Time: Place the plumeria seeds into the bowl of hot water and allow them to soak. The ideal soaking time is between 8 to 12 hours, or overnight, but should not exceed 18 hours. Over-soaking can potentially drown the seeds and negatively affect germination.

Overwinter your Plumeria indoors if you're gardening in zone 9 or colder, as these exotic growers will not tolerate a hard freeze. Move the plant indoors when temperatures drop below 45℉. Move your overwintered Plumeria into indirect light in the spring and resume watering.

Dip the cut (broken) end in a rooting hormone (some prefer one with a fungicide), then plant in a well-draining potting mix. Water, then allow the potting medium to nearly dry before watering again. Keep in a sunny place; rooting may occur within six weeks.

Seeds generally sprout in 3 to 14 days. On an average, you can expect a seedling to reach 6 inches in height in about 8 weeks. A one year old seedling will stand about 1 foot tall. After 2 years' growth, 2-3 feet tall, and 3-5 feet after 3 years' growth.
