hi! before christmas i left my Dieffenbachia seguine looking relatively happy but when i returned, all of her leaves dropped and then hasn’t improved over the past month. i got this plant on my first date with my partner so it’s very special to me and i can’t bring myself to even think about her being gone forever! is there any thing i can do? should i wait to see if it revives itself as it’s stems are still green? i’ve had her die and revive herself over and over again so i thought she was just having yet another tantrum! please help!
