Could we grow bonsai with normal seeds and techniques to grow it? Which bonsai is best for indoor and acts as an air purifier? Instead of buying it, I want to grow my own bonsai. Please suggest some tips.
Bonsai are normal plants or trees, that we find in large in nature. The art of bonsai is to recreate the real tree in a miniature form in a pot. So any (real) tree can be used for bonsai. However, trees with large leaves are more difficult to downsize in good proportion, so starting with a tree species that has small leaves is a smart choice.
Growing bonsai indoors, is tricky. You can use tropical species for this, like Ficus. I like the Bonsai Empire website where they guide you for proper maintenance.
