There are two varieties of Ashok tree. One with dropping branches and doesn't grow into a big tree, and the other which grows into a huge shady tree. The one that grows into a huge shady tree is known as Sita Ashok.
Get a piece of Sita Ashok tree root and keep it at the pooja sthan (Place of worship) at your home. That's it.
I hope the readers will get benefited.
