Background info:
I bought this Ficus bonsai (pictured) back in Early 2022 and the main trunk was severed, with a smaller branch growing from the side which can be seen at the front. Unfortunately, due to a change in environment, this branch died, however, I have managed to revive the plant with smaller thin branches growing out of the side of the trunk.
My question:
Is there a way to get the main trunk to grow back e.g., by applying bonsai cut paste or is it too late?
Thank you in advance.
