Orchids are basically so-called “short-day bloomers”. This means that most orchids bloom in fall, winter and early spring.
However, it is also noticeable that the shoot growth of many orchid genera also increases at the end of summer and the beginning of fall. Paphiopedilum or Odontoglossum, for example, produce young shoots, but root growth is also increased.
During this time, vegetative growth can be stimulated with the appropriate fertilizer, slightly higher temperatures and, if possible, additional light.
Most orchids that show increased shoot growth in the fall will flower in late spring. On the other hand, the species that have their strongest shoot growth in summer can be expected to flower on time in fall / winter. Environmental influences and changes in the outdoor climate often affect the flowering time from year to year, so that flowering can be delayed by several weeks.
All in all, it can be said that abundant flowering results from good and healthy shoot and root growth. In the genera section you will find tips and basic information on the most common orchid genera.
