please help me, i moved house 6 months ago, my orchids did well with the move but my new house is alot colder to my old one, i think my babies are dying. five of them have come into bud but thats it they go further. iv tried to move in into a warmer part of the house, but it hasnt done anything. what can i do thats not expensive, i only have 11 orchids and iv have them for about 8 years so im really worried for them.
