1
挑选一个红薯。幼苗是从红薯的芽点中长出来的嫩芽。你可以从网上或花卉市场订购红薯苗，也可以自己在家培育。从商店或朋友的院子里找一个成熟的，无病害的红薯。

确保天气适合种植红薯。红薯是一种热带作物，所以适合在天气较热的南方地区种植。如果要自己种植，可以在三、四月的时候培育红薯藤。然后等到五、六月份再移栽到地里。

准备好你的红薯。 当你已经有了1-2个健康的红薯，把它们放入水槽中洗干净。然后一切两半。如果红薯特别大，就切成三块或四块。

找个敞口瓶装满水。育苗工程由此开始。用一个敞口的瓶子或杯子，装满水，要能让红薯半截浸入水中半截露出水面。瓶口或杯口要大得放得下红薯，整个瓶要灌满水。

将您的红薯浸入水中。 在红薯外侧等距插入4-5根牙签，把红薯切口朝下置于装满水的瓶子口上，靠那4-5根牙签让红薯悬在瓶口，半截浸入水中。
切开的每一块红薯都这样分别放在不同的水瓶中。

把红薯苗放入水中。在碗中放入一些水，约3厘米或更少，取决于红薯苗数量。把红薯苗放入碗中，让其基部浸入水中。直至几天后，根从底部长出。
每天加一次清水，让幼苗健康生长。
把没有长出根或枯萎了的苗扔掉。

移栽。2-3天后，红薯应长出根。倒掉碗里的水，把你的红薯苗取出拿去种。最好是把它们直接种在院子里，保持根系完好，不要再分别种在盆里。[2]

在院子选一块地。 红薯主要生长在地下，不需要太多地上空间。然而，他们喜欢温暖的环境，所以尽量选择一个阳光充足（特别是如果你生活在北方）排水良好的地点。

松土。 红薯是块茎植物，在土里生长。要让它们长得好，必须深耕土地约30厘米，并把土壤弄松散，如有必要，加入园艺土壤。

3
处理土壤。 要想有好的收成，肥沃的土壤很重要。在表层覆盖一层营养土，把大块的石头捡走。测一下土壤的Ph值。通过添加泥炭土或草木灰，调节酸度或碱度，达到中性的pH值。这叫做土壤改良。
你可以在园艺中心或商店买到pH测试套装。

确定种植时间。 因为红薯喜热，它们需要有温暖的土壤，才能蓬勃生长。所以最早要到春天，最后一次霜冻后一个月，才能种植幼苗。

种植。 把红薯苗逐棵放置在事先挖好的洞，在茎上覆盖约1.5厘米土壤。红薯的叶子部分会向外长出藤蔓，而根部会在土壤15-30厘米深处长出块茎。

收获红薯。在种植后120天左右，红薯应该已经达到完全成熟。如果可能的话，尽可能推迟收获红薯的时间（在下霜之前），因为这样会长出更大更好吃的块茎。

红薯收获后的处理。红薯收获后，一定要进行后处理。这一步很重要。这能让红薯更香（刚被挖出时，它们没有香味），表皮更韧。把甘薯放置在温度摄氏29-35度，湿度80-90％的地方5-10天。之后，它们就可以煮来吃了！[5]

可以在大衣橱内或小房间里放置一个加温器和加湿器来对收获的红薯进行后处理。

存储你的红薯。这些可爱的块茎的好处的之一是，如果储存得当，它们可以保持新鲜好多个月，而且仍然很好吃。把它们储存在一个开放的，干燥的，气温在摄氏21度左右（这意味着不要冷藏！）的地方。决不要在一个塑料袋或密封的容器内储存红薯。[6]
