| Nobile-type dendrobiums grow adn bloom on a yearly cycle. It takes several months for the canes to grow and mature. Fertilizing them and doing other things might make them bigger and stronger but you can't really speed up their growing cycles.
It is normal for nobile-type dens to not bloom on this year's canes but to bloom on last year's canes. The canes that grew in the spring/summer of and matured in the autumn of 2007 will probably not bloom in the winter of 07-08. They'll probably bloom in the winter of 08-09.
