I bought a 2 foot variegated banana tree this spring. It's doubled in size since then. First I put it in full sun and it did great but the variegation went away, then I put it into what I consider deep shade and it never came back. I moved it in the house and I wanted to know will the low light make the variegation return or will it just etoliate? Am I not giving it some sort of micronutrients I should be?
