偶行偶素隨筆
清風，流雲，閑散，飄逸。
一直都很喜歡吃紅薯尖，可是本地的東方店不賣這東西，想吃就得自己種啦。有一年的春天在農貿市場買到過紅薯秧苗，種在地裏，隔三差五地剪些紅薯葉尖回來清炒，味道比空心菜還好！那一年吃了很多紅薯尖，秋天還挖出二十多磅紅薯，真是省事兒又高產的蔬菜。可惜後來再沒有買到過紅薯秧苗。
試過把紅薯埋在地裏，期望能長出苗來，沒成功！也試過自己育秧。照網上搜來的方法：把紅薯豎著切成兩半，切麵朝下接觸潮濕的育秧土，放到窗台上去。勤澆水，保持土的濕度。後來倒是發出不少芽苞。怪自己心太急！本想趁著太陽天搬到陽台上曬曬，不想被太陽灼傷，又被寒流凍過一次，那一年就沒吃上紅薯尖。
去年夏天回國去了，就沒顧上這檔事兒。
今年我再試紅薯育秧。在網上找到個新方法。這是我用此法育成的秧苗。
這種方法就是太慢。很考耐心的說。
另外，見到園藝用東方店買來的紅薯葉的梗子育秧的做法，也想試試。於是趁老公出差的機會，打發他專門從外地的東方店帶回來兩包紅薯葉，把六七十截紅薯藤插到地裏去，成活的隻有十來棵，就這樣我已經是無限歡喜了。
如法炮製，把一些空心菜的杆子插到地裏去，也成活了。旁邊是從園藝那裏要來的馬蘭頭，長勢喜人哪，哈哈。。。

Grow a Sweet Potato Vine
Sweet potatoes in the U.S. are grown mostly in the South. They are planted in the spring by "slips." These are the small rooted pieces of the vine that grow from the "eyes" or buds of the potato.
The sweet potato produces vine-like stems that resemble the philodendron plant. Place the sweet potato in a container of water. Keep the top 1/3 of the potato exposed by placing toothpicks into the sides. The pointed end should be down in the water. In a few weeks a vine with several stems will begin to sprout. The stems are weak; tie the stems to a stake.
Sweet potatoes like a bright, sunny location and require care like house plants such as ivy.
Fertilize about once a month.
If the sweet potato vine gets too long, cut it back a few inches to force the vine to get bushier. The tip of the vine that was pinched off can be rooted in water or moist soil.
Your sweet potato vines can be planted outside in late May to produce sweet potatoes that can be dug and eaten in the fall.
