i bought a bleeding heart offline little bigger than a seedling...when it arrived the stem had been broken in 2 places i sellotaped it at the bottom snap (i couldnt think of any other way) and proped the top snap upright and sellotaped it too. the top eventually died off and i didnt cut it or cover the wound and now the stem is completely brown. another stem has snapped at the bottom and going brown to i no they are fragile plants either the stem has snapped because it was to heavy or its snapped because the bottom is browning i havent a clue...is it dieing ?? or can i save it??.
