Tuberous Drosera are native to southernAustralia, Tasmania,andNew Zealand.A few species like the Drosera peltata-group and Drosera macrantha arewidespread but most are narrowly endemic to the state of Western Australia. Tuberous Drosera live inareas where winters are mild and rainy while summers are hot and dry. Thetubers sprout in early fall and begin vigorous growth with the first rains. Bylate spring the plants have bloomed and they die back to the undergroundtubers. The tubers over-summer in warm barely damp soil.
球根茅膏菜的原生地大多分布在南澳、塔斯马尼亚和新西兰。一些品种如光萼茅膏菜、大花茅膏菜分布地就十分广泛，当然大多数都只是狭窄地分布在西澳。球根茅膏菜分布在冬天温和多雨、夏天炎热干燥的地区。球茎在早秋发芽并在第一场雨后迅速生长。到了晚春它们就会开花，之后地上部分死亡，转化为球茎形态。
Most tuberous Drosera are quite challengingto grow unless you can provide their exact requirements. The Droserapeltata-group species and D. stolonifera are the most forgiving of adverseconditions and recommended for beginners. As long as the plants are kept cooland get lots of light, they are very tough and easy to grow. Most can takelight frost. But temperatures above 25°C ( 78°F ) can cause them to die backand will kill seedlings. If the plants have not built up enough nutrients inthe tuber to recover from the warm temperatures, the plants are history.
大多数的球根茅膏菜是很难种植的，除非你提供他们需要的额外设备。而光萼茅膏菜一类的球根茅膏菜和匍匐茅膏菜需求的环境不高，适合新手种植。大多数球根茅膏菜能够扛住轻霜。但是温度一旦高于25度它们地上部分又会死亡，而且小苗的生存也会受到威胁。如果植物没有在球茎里储存足够多的养分来从休眠中复苏，那么你将再也见不到它们长出来。
Most tuberous Drosera do NOT make goodterrarium plants. If your house is cool enough during the winter, you couldrotate them into a large terrarium or grow them in a very sunny window or underbright lights. However, you usually either need to have a cold greenhouse ifyou live in cold winter climate or if you live in a so called Mediterranean climateyou should grow tuberous Drosera outside all year.
大多数的球根茅膏菜并不适合养在缸子里。如果你的房子在冬天足够凉爽，你也可以把它们种在很大的缸里面，并放在有充足阳光的窗台。当然，你要是住在冬天凉爽的地区那么最好有一个降温温室，而如果你住在地中海气候地区（原生地气候）那么可以把它全年种在室外。
The tuberous Drosera seed must be plantedin summer or early fall since these species are winter growing. The seed ofmost species will not germinate unless they have experienced a period of warmor hot stratification as would be experienced in summer. In the northernhemisphere this means you must plant the seeds by the first week of August(down under that would be February). The soil surface needs to be kept dampduring stratification. Drosera hookeri, D. auriculata, and D. macrantha willgerminate if planted by the first week of September (March in the southernhemisphere). Cold stratification such as is used for Sarracenia and temperateDrosera is NOT effective with tuberous Drosera. The seeds appear to requirecycling temperatures, temperature transitions, and/or light cues to germinate.Expect the seeds to start germinating in October and November (April and May inthe southern hemisphere). Seeds planted late may germinate in the spring.Depending on your growing conditions this will likely end in tears as thetemperatures could get too warm and the seedlings not live long enough to maketubers.
因为球根茅膏菜在冬天生长，所以它们的种子一定得在夏天或者早秋播种。它们的种子如果没有经历一定时间的高温期就不会发芽。如果在北半球那么你必须在八月的第一个星期里播种（相当于南半球的二月份）。土壤表面在发芽期间土壤表面必须保持湿润。盾叶茅膏菜的一些变种和亚种要在九月的第一周种植就会发芽（南半球的三月份）。像对于瓶子草和温带茅膏菜的低温处理对于球根茅膏菜没有什么作用。种子发芽需要转周期性的温度变化或者光照变化来发芽。如果种子不在十月和十一月发芽，推迟种植的种子会在春天发芽。根据你的种植环境，因为温度之后会过于温暖、小苗来不及结出球茎就死亡了，这样子会给你带来不愉快的后果。
Some tuberous Drosera species with hardseeds germinate better if they are scarified before planting. These speciesinclude D. stolonifera ssp. stolonifera and D. gigantea. Please see the page onDrosera seed scarification for more information.
一些比较坚硬的球根茅膏菜种子要划伤后才会有比较高的发芽率。这些品种有匍匐茅膏菜和巨大茅膏菜。请移步茅膏菜播种页面获取更多信息。
Tuberous Drosera require very deep pots andcan not be transplanted when growing because their roots are very long and veryfragile. Use 16 cm deep nursery #1 ("gallon") pots to start seeds. A1:2 mix of peat and sand with some sphagnum moss in the bottom blocking thedrainage holes works well. Let the pots sit in about 2 cm of water. In mildwinter areas you may leave the pots outside and let nature takes its course. Inother areas you may start the seeds in a greenhouse that allows the temperatureto get down to a few degrees above freezing at night. The perfect location isin the trays with your Sarracenia plants although it is probably best toprotect the pots from rain and top watering as the rain could wash out theseeds and encourage moss, liverworts, and other weeds.
球根茅膏菜需要很深的盆子而且最好不要移植，因为它们的根系十分的长而又十分脆弱。用16厘米深的盆子来从种子开始。1:2泥炭和砂的混合介质再在底部加上一些水苔挡住排水口。把盆子放在1到2厘米深的腰水中。在冬季气候温和的区域你可以把盆子扔到室外令其在自然条件下生长。其他区域你可以把种子苗放到温室内种植以保持不要冻结。
If the seeds don't germinate the firstwinter, don't throw out the pot! Let it dry out during the summer and try againthe next winter. These plants require some patience.
如果种子没有发芽不要马上把他们扔掉！在夏天的时候让盆土自然干燥之后在冬天继续尝试，种植植物需要耐心！
After the seeds germinate, the challenge isto give them enough light at cool temperatures to produce tubers sufficientlylarge to get the plants going again the next winter. Most species appreciate afoliar feeding of half strength Miracid every two to three weeks. Only mist theleaves; don't fertilize the soil. Do not force the plants to go dormant. Thisis especially important for seedlings. If there is a heat spell in the spring,put them in a cool location to delay dormancy.
种子发芽以后，最大的挑战就是在冬天给予他们足够的阳光来促使长出足够大的球茎，以此坚持到下一个冬天。大多数种类的球根茅膏菜喜欢每两到三周进行叶面追肥。只是对叶面喷雾，不要弄到土壤中。不要强迫植物进行休眠，特别是对于小苗。如果春天过于炎热，那么就把它们放到降温设备中种植来推迟休眠。
When the plants do die back, let the potsdry out. For most species you can let the pots get completely dry if they arestored in a humid location out of the sun. Drosera gigantea and D. sulphureashould never be allowed to dry out completely. A technique for storing the potswith tubers over the summer is to allow the soil to become just damp and thenput the pots in plastic bags or in a terrarium in a shady location or under agreenhouse bench. A terrarium with gravel and some water in the bottom worksbest as it is easy to keep an eye on the pots and to check for new growth inthe fall.
当地上部分死亡后，让盆土保持干燥。对于大多数品种你可以令土壤干透并把盆子放在阴凉湿润的角落。例外的是，巨大茅膏菜和硫磺茅膏菜绝对不能干透。技巧就是用袋子把盆子封起来放在阴凉处保存。在容器底部放一些沙子并加少许水就可以很好地做到这一点，而且这样可以随时查看是否有新的芽从土壤表面冒出来。
The only time you can transplant tuberousDrosera is when they are dormant. If you are getting too many plants in a pot,carefully dig up some of the tubers a month after they die back and put them innew pots at the same depth they were originally at in the old pots. They areusually 5 to 10 cm deep. Don't throw out the soil in the top 10 cm of the potunless you also want to throw away small tubers. Don't wait until the fall todo the transplanting as many species try to get a jump on winter by sending upa sprout to just below the soil surface in late summer. Do enjoy thesewonderful ephemeral plants!
你唯一能够移植球根茅膏菜的时间就是当它们休眠的时候。如果你在盆子里种了太多的球根茅膏菜，那么你就要在地上部分死亡后一个月把球茎小心地挖出来，然后分开种植到新的盆子里，深度和挖出来之前保持一致。不要把盆子上半部分十厘米的土壤扔掉除非你也想把那些小的球茎一起扔掉
Tubers may be stored in plastic zip-lockbags in a dark location. Plant them with the "eye" up. You may findit easier to maintain mature plants if the top 3 cm of the soil is pure sand.
球茎可以装在塑料自封带放在黑暗环境下储存。种植的时候把芽眼朝上种植。你可以发现如果上部三厘米都使用纯砂，你会发现成熟植株很容易保存。
