Tuberous Drosera (Section Ergaleium,Section Stolonifera and Section Erythrorhiza )
I use a mix of peat and sand ( 50:50 ) and a layer of squarts on the top of the pot.
They grow during the winterperiod, so they start growing at the end of the summer when the temperatures go down.Temperatures between 2 and 20°C are fine. ( 35-68 Fahrenheit )
Keep them wet during the growing season until they die at the end of spring. During the summer, keep the pots moist and put them in a shady place. Only watering when the pots are drying out.You can check the tubers when they are dormant , most of them make additional tubers during winter.
