Did you know that the leaves of sweet potatoes are edible? It's in the morning glory family, not related to potatoes. I tried to grow them one year and ate a couple of the leaves. Bleah. Tough and fuzzy is how I'd describe them. Maybe they'd be ok cooked, but I didn't try it. Didn't get any sweet potatoes, either, so that was a one time experiment.The sweet potatoes are doing well! I’m sure they were a bit miffed by the cold (48F) temps early this morning, but otherwise all are sprouting new leaves. Many of them (10 varieties) have kept their leaves that were present upon delivery. But, some of them have lost all their original leaves and are producing all new ones. Oh yeah, I’m going to be in trouble in a few weeks with all the vines…along with the melon vines…
I do the same, I let the plants totally die before I did the potatoes. I mark where the plant was with a stake so I know where to dig. I usually leave them in the ground until they start talking about frost. I have enough to do at that time of year, so mother nature can store the taters for me for a couple weeks.Potatoes are starting to turn yellow. I could dig them now, but I remember Papa's potatoes were always nearly dead when he dug them. I'll wait another week.
But, your climate is totally different, so this might be no help at all...
