I bought an unknown flowerless orchid 2 months ago. It has 2 'old' bulbs and 1 current bulb with 2 new growths. Each bulb is a ridged, narrow, flat oval; they're of increasing height, with the new growth being tallest. My problem, aside from not knowing its identity, is that it seems weak. The leaves are a nice dark green but seem limp and lifeless. New roots are growing from the 2 new growths and they seem healthy. I don't know what to do, if anything. Any advice would be much appreciated. Thanks!
