ok my mom moved this following plant from one part of my living room to another. to my regret and all the blooms shriveled and fell off. so i unpotted my phal baldans kaleidoscope 'golden treasure' from spagh and it had a mass of rotting roots. i cut all of them off and was left with a few dying looking things. i dont have any fresh spagh or a pot so im putting it in a vase. the leaves feel a little limp but the whole plant looks healthy still. its plump and i see the beginnings of a new leaf in the center. its been in the vase for like 5 days now and idk of itl do good and i dont want to lose it. the roots are broken in several plaves where theres black mush but smaller segments of helthy root attached together by the center filament. are they still helping the plant even though they aren't attached to the plant with root just that cord thing in the center? the leaves have some small blister looking things. whats the cause? im afraid that the vase is getting too cold and might hurt the plant. when i touch the leaves theyre super cold. plus its alone in the living room without humidity or heat. is that bad? how do i cure the roots and get rid of the rotten sections so that i can maybe repot it(hydrogen peroxide, alcohol, mouthwash?) its wierd how the moss in the center of the root mass(i found like 5 layers of different mosses still condensed in the shape of the previous pots where im assuming the grower dropped on the plant)was fresher than the outside moss. oh yeah, i left the spikes on it beacause one of the nodes seemed promising but seeing as how its being stressed out right now, should i cut them off so the plant concentrates on growing? my three phals including the one above havent grown ANY new roots. they just have the same ones they came with. why is this? the other two(dtps. i-hsin sun beauty and dtps. shih hua gold) are in bark. the third (baldan)is the one i wrote about above.
