Drosera is a hugely diverse genus. It's species may be found all over the world, in Africa, N. America, S. America, Australia, even the tropics. Humidity is generally a requirement for all species.
Tuberous: Tuberous species generally require summer time temperatures between seventy five and ninety degrees. Strong light is also required. It is recommended to have a 13-14 hour photo period a day. Winter temperatures can range anywhere between 30 and 50 degrees. High humidity is required to grow these plants.
Temperate: Summer time temperatures between 70 and 90 degrees are necessary.
High humidity is also a must during the growing season as it decreases when it enters dormancy.
Tropical: Summer time temperatures should between 75 and 95 degrees with a high level of humidity. Wintertime temperatures should be between 60 degrees and 80. Intense light is required with more then a twelve hour photo period for winter and summer time.
Pygmy: In the summer time, temperatures between eighty and one hundred are required with drier conditions.
Dormancy: Dormancy is only required for a few groupings of Drosera and for varying amounts of time. See below for specific instructions for the groupings.
Tuberous: The tuberous plant goes dormant in the summer time so dry conditions are necessary. Keep temperatures high.
Temperate: Dormancy is required in the winter time for about 5 months. Humidity and moisture should be dramatically reduced during this time. Dormancy temperatures should be between 35 and 45 degrees.
Tropical: There is no dormancy requirements for tropical drosera.
Pygmy: It is characteristic of pygmy drosera to go dormant during the summer in hot temperatures but is not always necessary. This is simply a mechanism for surviving harsh conditions.
