The sweet potatoes in the moist dirt are supposed to be starting to grow slips. This takes quite a while to get going and all the time I can't tell if it is working or not. BUT it all worked last year, so I'm hoping it will work this year! Eventually there will be green leaves just tumbling out of that plastic bucket. The potatoes are also "chitting" (I think it is the word). I'm trying to grow out some eyes before I plant them. By letting the eyes grow a bit (supposedly) you get a jump on the season.
