「再生」薯仔 Grow Potatoes From Sprouts

FB-Get-Involved-001

我們都知道薯仔發芽後會有毒素,不能食用。覺得扔掉太浪費的話,不妨用來自種薯仔。薯仔粗生粗養,不需細心的照料,三個月後便能種一得十,挺過癮的!

種植重點
• 薯仔是茄科作物,種植薯仔後的泥土不適宜立刻種植其他茄科作物。
• 適宜在秋天至春天種植。
• 土壤:選擇砂質土,即排水良好的土壤,否則水分過多,薯仔容易腐爛;而且盆子要有一定的深度。
• 薯仔品種可依個人喜好選擇,來自外國的紅皮、黑皮薯仔、日本的男爵薯,只要能夠發芽都適宜種植。個人經驗分享,試過在某日式超市購買了「男爵薯」和「五月皇后」,但苦等了三、四星期都毫無發芽跡象,估計是運用了防發芽的高科技品種,所以若等了兩星期薯仔都沒有發芽,最好購買其他種類再作嘗試。

種植過程
1. 將發芽後的薯仔切成一半,或將發芽部位連一撮果肉切下,不要馬上種植,否則切口容易腐爛。
2. 切口上灑上熟石灰或爐灰,放在通爽位置風乾一至兩天,可減低腐爛機會。
3. 種薯時,切口朝下,然後覆土5cm,即使蓋過芽的位置,憑著旺盛的生命力,它都可以自行鑽出泥土表面,快高長大。
4. 薯仔種植數周至一個月,芽就會從土裡冒出來;為了能收成結實的馬鈴薯塊莖,只留下兩棵最強壯的芽,其餘拔去。
5. 種植期間若有薯仔露出,需要蓋泥培土。
6. 種植前,不需要施基肥,摘芽後每星期施半湯匙熟石灰或雞蛋殼。
7. 約三個月收成,底部的葉開始枯黃就可輕撥泥土查看薯仔是否碩大。收成要選一個天氣晴朗的日子,若打後數天也是晴天,可減低薯仔霉壞的機會。

The lovely potatoes will become poisoned when there are new sprouts, which are not safe to eat. But throwing them away seems to be a waste, so what to do with the sprouting potatoes?

They are definitely not safe to eat, but we can use them to grow the new potatoes!

Steps

•  Before planting potatoes, place the spuds you want to plant in a warm, sunny spot. The warmth will encourage sprouting, and exposure to sunlight makes the skins turn green and bitter. This makes them less appetizing to critters.
•  cut the sprouting potatoes into half, or into pieces that have at least three puckered “eyes” on each piece.
•  After you cut the potatoes let them sit overnight to dry out the cut so they will not rot.
•  Place the potatoes in a box, plant them cut side down and sprouts on top, then cover the potatoes with 2 inches of soil. ( no worries if the soil covered the entire sprouts, it won’t harm)
•  You will see the sprouts come out in a few weeks time. You may pull them off and just leave the strongest two behind for better quality of new potatoes.
•  Check the potatoes every week and add more hay as needed. The hay will help keep the soil cool.
•  Adding 1/2 tablespoon of lime powder or egg shells every week.
•  Harvest the potatoes when the vines are dead; this will take around 3 months. Be careful not to poke or squeeze the potatoes when you harvest them. Try to harvest the potatoes in good weather. Allow the potatoes to dry in a cool place. Keeping the potatoes dry and cool is important for preventing rot.
