help! has she grown too long?

hi friends! i have a beautiful plant that’s been in my window for almost 3 years… shes grown incredibly, but now im noticing some of her leaves are starting to wither (see photos). it’s only 2 or 3 leaves, but ive never pruned her or done any kind of trimming, i just add soil as needed and keep her well watered. she’s been thriving, but im concerned she needs some kind of care that i don’t know about as a relatively new plant mom! im wondering if it’s time to do some trimming? perhaps you have some suggestions for what to do about these leaves? perhaps nothing, it’s normal? any best care practices? do the roots look okay? thank you all so much!!! really appreciate your guidance!!
