manipulating life cycle in nobile type dends.
I now have several nobile type dends. I know the basics for maintaining
them, but I am a little concerned about one of them. It has just dropped the last of its flowers, but it does not appear to have any new growth other than two keikis. Is there anything I can do to stimulate the production of new pseudobulbs? Although two others are presently in bloom, all of the others have new growth. Also, with these dends, what are the limits on how often they can be induced to bloom. For example, living in Ontario, I can arrange for two periods of quite cool temperatures, at which time I can easily arrange for them to be dry too. Obviously these periods would be six months apart: spring and autumn. Would they be able to complete a cycle of new peudobulbs produce and flowering in six months, or do they really really require the better part of a year to grow followed by a resting period of several months of cool dry conditions? In other words, just how short can these two phases be? I understand the origin of the annual cycle, but in cultivation just how adaptable can they be? Cheers, Ted |

Cheers, Ted Although you may be able to manipulate the cool temperatures, you are unable to manipulate the warm temperatures and sunshine in Canada. Nobiles flower on mature growth, and in nature this is after the end of the second year, with the first year being interrupted by cool weather, which initiates flower production on the previous years growth which has now matured. The only one I know of that manipulates flower production in nobiles is Yamamoto, in HI. If you will note new flowering plants from his nursery, you will see that flowers are on this years growth; and there is usually new growth which in your growing area will not flower until two years from now. He does this by growing this years growth to maturity, at sea level (warm) in HI, and then taking them to his other nursery in the mountains where they receive cool temperatures which initite flower formation. |

Hi, and thanks,
Although you may be able to manipulate the cool temperatures, you are unable to manipulate the warm temperatures and sunshine in Canada. Want a bet? While I can't affect the weather outside, I can arrange for the plants to get lots of heat and light indoors. You see, my sister keeps the thermostat cranked up high during the winter to I find it almost as hot inside during the winter as it is during most of the summer. Needless to say, the heating bills this year were brutal. Nobiles flower on mature growth, and in nature this is after the end of the second year, with the first year being interrupted by cool weather, which initiates flower production on the previous years growth which has now matured. The only one I know of that manipulates flower production in nobiles is Yamamoto, in HI. If you will note new flowering plants from his nursery, you will see that flowers are on this years growth; and there is usually new growth which in your growing area will not flower until two years from now. He does this by growing this years growth to maturity, at sea level (warm) in HI, and then taking them to his other nursery in the mountains where they receive cool temperatures which initite flower formation. This suggests that my nobiles may respond. And if they don't, I can live with an annual cycle. But it would be fun to try to see what happens. Cheers, Ted |
