I recently acquired a Philodendron Selloum from a friends garden. They were moving and I was given permission to take a section from her own, which there were several of them covering about a 15 foot radius. I used a very sharp knife and cut diagonally on the roots (the ones that laid on top of the soil and as well as into the dirt where the heart shaped palm-looking trunk was. The palm-looking trunk I took home was about 8 inches long and four inches wide and there were 3 large stems/leaves to the section I took. Immediately after cutting the roots, I gently wrapped the roots/trunk in a damp rag and immediately planted it in a gallon size pot with soil mixture made for palm plants when I got home. I put it near a window that gets indirect light from the morning sun which lasts only about 3-4 hours at its brightest. I watered the plant with a miracle grow plant food (about 1/4 tsp with a gallon of water). This is all that has been done since removing it from my friend's yard and I am afraid I shocked the plant beyond repair because one of the leaves is predominately yellow now and very wilted, stem pretty thick and sturdy though. A second leaf is still green, but looks yellowish (perhaps in the beginning stages of whatever happened to the first one I just mentioned). The third leaf is as is when I took the plant home. I am hoping someone can shed some light on what went wrong and how I can save this beautiful plant! Photo before and now attached. Someone, please help!!
