i will be the second or third person to tell you it NOT A WATER issue... but continue to ignore such if it makes you happy ... you arent doing harm with your idea.. but it isnt going to solve the problem .... my bet is .... and i see you are rooting more plants in the same pot.. that you have significantly OLD MEDIA.. that is used up.. and not allowing proper MOVEMENT OF WATER THRU THE WHOLE ... its still a water issue.. but not the one you are fixated on ... get those babes their own pots.. and repot the big one ... and if it dies.. you still have it.. because those cutting are the same plant.. exactly ... and move them closer to a window.. as there may not be sufficient light in what looks like the middle of the room ... there is a houseplant forum if you wish to delve further into the proper culture of houseplants ... all this is that your mom would have done if she was any kind of houseplant gardener .... the best idea.. would be to pot up the little ones fist.. and in a month or so.. when they are all fat and happy.. and your have your failsafe.. you can give it a go on the big one ... and what they said on the lowest leaves falling off... they do that annually.. no plant holds it oldest leaves forever ... and just to be sure.. potting media is NOT dirt from the yard ... good luck ken

Where is this located ? Could be Puya.

The yellow flowers and small hairy fruits suggest Cucumis melo ssp. melo. Cucumis melo ssp. agrestis is similar, but its fruits are smooth.

Top looks like a mulberry branch with a Fabaceae vine growing on it. Could even be a bean. Can you show us a picture of the vine's own leaves? Is it growing in a garden or in the wild?
