I bought a nice Lady Slipper in bloom last March. Got it home and the flower dropped, of course, but the plant still looked very healthy. By late summer of 2006, the lower leaf tips started to turn black. I cut them off, but they still kept turning black. I have repotted into a semi-hydro mix, thinking more humidity would help, but to no avail. I went to an orchid show and showed my picture to a grower who suggested using purified water to water the plant. I've done that, but it is too soon to tell if that will make a difference. I don't see any new buds forming, but the plant has grown new leaves. Any ideas about the black tips? Any help is greatly appreciated. Thank you in advance.
