Germinate Plumeria From Seeds
Germinating plumeria from seed is fun and very rewarding. Seedlings that grow from seed have a stronger root system. And the most important thing—they will have a unique color no matter which parent tree they are from! There are many different ways to germinate the plumeria seed. Here is what I found to be very successful.
Step 1. Soak the seeds overnight with B1 solution or warm water.
Step 2. Prepare your growing medium in a container. You can use potting soil or mix your own soil by combining coir and perlite 50/50. Peat moss can be used to substitute coco coir. Put them in your growing container /pot.
Step 3. Lay the seeds flat, space about 1 inch apart.
Step 4. Cover the seeds with a thin layer of soil.
Step 5. Water them with B1 Solution and you are done! Only moisten them when the top soil looks dry. Within 3 months they are ready to be transfer into a bigger pot.
They love warm temperature and high humidity. Cold and wet is what kills them. Using the geminating station kit from Hydrofarm would be an ideal. They will germinate faster within a week over a heat mat with a moisture dome.
