i have a beautiful orchid that flowers quite a few times a year. i did think at one point that i was getting more leaves or stems but it now seems that these stalks are growing ourtwards and look like roots? they can be bright green on the tip. when tony blair was being interviewed on tv recently there was an orchid in the background and it had the exact same 'roots' growing outwards on it. so, what should i do, cut them off , repot it though already in a huge pot? also now that the flowers have dropped off in the last week there are 2 more stalks a bit like antlers growing off the main one and looks like more flowers are due. can i get anymore stalks branching off by making a V cut into the stem?
