The Carnivorous Plant FAQ: Sarracenia cultivation

A: Sarracenia is really not hard at all to cultivate, as long as you follow The Rules. If you deviate from The Rules, Sarracenia are either hard or impossible to grow. The most common causes for death are inadequate lighting, incorrect soil or water, or inadequate winter treatment by growers in tropical climates. Sarracenia are pretty straightforward plants - if they are unhappy with their growing methods, they die. There is very little lingering involved.

Between 16/18 ° C and avoid that relative humidity is superior, since with cold temperatures the plants require less humidity. With all this I maintain a humidity around 60/75% day and 70/80% at night.

Lighting: Sarracenia, especially the erect trumpet species, requires extremely high sun. This means that they are not suited for terrarium culture. Simply put, do not try to grow erect Sarracenia in terraria, indoors, or in partial to full shade as they will never get enough light. Symptoms of insufficient lighting of your erect trumpet pitcher plants are pitchers that are floppy or poorly colored. The pitchers should be able to support their own weight, although you can expect some floppy pitchers to be late in the season for S. alata and S. rubra-complex plants.

The prostrate species - Sarracenia purpurea, S Psittacina, and S. rosea - can survive and even thrive in lower lighting conditions such as you might expect in a terrarium or windowsill. It is pretty obvious these shorter plants are adapted to the decreased sunlight they experience in the wild because of competing, taller vegetation. If you want to try to grow Sarracenia in a terrarium, start with these species or hybrids involving them. By the way, the seedlings of most species of the well in terraria, until the seedlings are a few years old.

Soil: Sarracenia are not too picky, as long as it is zero-nutrient, acid medium. I recommend 50:50 sand: peat or Sphagnum, but something similar should be fine.

Temperatures: Use something like to learn about the seasonal variations your plant will expect. Use "Mobile, Alabama" to learn about Gulf Coast plants, and "Wilmington, North Carolina" to learn about Green Swamp plants. If you have a Sarracenia purpurea from some northern area, I suspect you already know what to do. The same goes for the rare Sarracenia species.

Winter treatment: Sarracenia expect spring, summer, fall, and winter seasons. During the spring, they flower. During the summer, they produce their first pitchers early in the season. During the fall, they just sit there; Some species make modified, nontrapping leaves during this season. During the winter, the remains of the summer leaves slowly die back. I think winter rest is signalled by cooler temperatures and / or decreased photoperiod / intensities, but I do not really know. You can take advantage of this slow season by trimming the leaves back as they die. Only trim off the dead stuff. Sarracenia oreophila, S. jonesii, and S. purpurea subsp. Purpurea expect cold weather and even frosts during the winter. If you keep your plants on a seasonal schedule, they will usually flower for you each spring. This means they are happy!

Feedings and fertilizers: Every now and then I will throw a dead cricket into one or two pitchers, but only for the plants I grow in terraria. I never feed bugs to my outdoor plants because they capture plenty of their own bugs. I have even heard from people who have to stuff cotton plugs in their pitcher plants because they catch so many bugs the plants suffer!

Contrary to conventional wisdom, some research indicates that sarracenia do respond well to slow Release soil fertilizers, although I encourage you to read the original study by Brittnacher (2009) to see how it was done. I do not use fertilizers, nor do I recommend them to beginning growers. My plants do great with the bugs they capture. If you kill your plants because of fertilizer toxicity, complain to whoever told you to fertilize. Do not whine to me because I will show you no mercy.

Vegetative propagation: If your plants are growing large they are splitting open the pot, you can divide them. This should happen only every three years or so. Of course, you can divide more frequently if you want to send a plant out to a trading partner. Gently rip the plant into pieces, making sure that each one has a few roots and a growing tip. Actually, it does not even need roots or a growing tip - a chunk of rhizome, potted and treated like a mature plant, can make both roots and a new growing point, if you are a skillful grower. Different growers have differing views on the best season for making divisions. I prefer to do it in the spring, just when the first pitchers or flower buds reach a few cm tall. Expect that a plant that has been divided might make distorted pitchers for the first year after suffering the abuse of propagation.
