How to grow bird of paradise plants from Bean Pods

Germinating the seeds for this Mexican Bird of Paradise will be easy! Simply soak the seeds from the bean pods in water for 48 hours or like many people use a damp paper towel.  If you are using the paper towel method to germinate your seeds-when a white shoot appears-plant it with the white shoot facing DOWN.

To plant and grow your bird of paradise — plant the seed in peat pots.  Cover the seeds lightly with damp vermiculite or your choice of a good soil.

Bird of Paradise seeds need at least 8 hours of sun, but not direct sun it will be too hot! You can start to give them a little more direct sun after the first leaves appear.

Peat Pots are great and make growing and transplanting your Mexican, Yellow or Red Bird of Paradise seedlings much easier. Start your seeds indoors and when you are ready to plant your Bird of Paradise just put the entire pot in the ground. Roots will penetrate the peat pot and the pot disintegrates enriching the soil.

I pruned mine a few weeks ago with a sharp pair of garden sheers. Many people cut these plants almost to the ground. I don’t, I prune my Red Bird of Paradise bushes about 18 inches from ground level.
