ms plant expert...

i have a question.

i have a wax plant that is an off shoot from my grandmother's plant. she passed away before i was 1...so...over 40 years ago.

i have never gotten my plant to flower. hubby has "helped" and over watered it a few times. it's really not looking well. it's still pretty green, but it's not full like it used to be and only has one long shoot hanging down.

any tips?
