One of my favorite trees here in SoCal is Erythrina Americana aka Colorin, Frijol Rojo, Cuchillitos or Naked Coral. Native to Mexico, they are so named because they flower while the tree is bare, before sending out leaves. These are quite easy to propagate large branches.
First it needs a period of dormancy and to heal the cut site. 4-6 weeks in a cool, dry, dark place. For me, the closet worked fine. After this period, simply score the bark vertically along the base, apply rooting hormone and stick it in soil. Allow the soil to fully dry out between watering. Spring time is best, while it is bare, but before budding has started. Soon you will have a flower and then lots of leaves.
Here is the parent tree:
And here you can see it in flower back in March/April
This was one of my earliest trees a couple of years ago when I first got serious with Bonsai. It was October and strong winds had felled a huge part of the tree in the park. This branch looked like a little tree already so I did some research to find the propagation method. Since then I have found that Springtime is a much better time to go for it - my first one sat from Oct. to March with no growth. Since then I’ve propagated branches w just 2 weeks dark/dormancy.
I am still learning about how to care for this tree, but one question I have - the first one I collected, this spring I put it in this large training pot. I used a premix akadama/lava/pumice. The leaves it produced are smaller (great!) and a touch pale/yellow compared to the parent and my other propagated branches.The others have been growing in cactus mix. I wonder what type of soil would be ideal for this species?
Anyone else have experience with Naked Coral?
