for some context, this plant has been hanging here and living for over 15 years in this one spot. i dont recall my gma ever using fertilizer of any sort, she claimed she “would check and see if the soil felt dry from time to time and give it a bit of water” which doesnt give me a very good metric lol. i dont know what kind of plant it is, i am pretty sure it is the same kind as the plant pictured in the last photo (this more-lively one hangs in front of a north facing window that doesnt have blinds). the dying one hangs in a west-facing window and always gets direct sun each evening, i have tried to give it a bit of water when i feel its dry one-knuckle deep into the soil, but it has been withering more and more in the last several months. any plant-id’s or advice on how to save it is appreciated.
