If the bean vine is winding around a cob, just gently unwind the vine and move the vine around the main stem. The vine should start growing around the stem on it's own tomorrow.

Your corn stalks seem short, not sure what the issue is but you have to pick the corn while it is good. Not an expert at picking corn, but when the silk hair ends start to dry out, the corn is ready to eat. You also can feel the top of the cob. When the kernels are filled up it will be more rounded and less pointed, if the tip feels very pointed the end has not filled in yet.

In any event, you can always gently pull back some of the husk of the biggest cob and see how it looks for eating. You don't want to pull back on too many husks since that makes it easier for bugs to invade. Eat a couple, judge from that when you want to pick the others.

Did you side dress the corn with fert when it was knee high and again once the tassels peek out? If not then the corn plants and ears may end up rather smallish. The bean plants don't need side dressing with fert since they produce their own N source but that's not enough N to help the corn much. Side dressing with fert may be difficult to do when you have the 3 sisters method which grows overcrowded in time.

As Robert above said you can peel back some of the shuck to check out the corn kernels, but know that corn matures from the bottom of the ear upward to the top so the top will be the last area to plump up, and sometimes the tip is bare due to incomplete pollination. Judging the ripeness by silk color is not always reliable but generally when the silk is dark brown (not black - too late) is when it's usually ready to pick.

Concur: Early Sunglow is naturally a small plant, one of the best of early yellow.s. Your photos show it is about ready. It is better to o pick an ear too early, then have a whole row get hard. Drying silk is a good indicator, followed by feeling the ear, and opening the tip of the husk and taking a peek. Yor beans have not overwhelmed the corn. so you should be able to cut the ears and remove them carefully.

Thank you all! I did as suggested, very gingerly unwound the vines ( which was easier than I had feared) and managed to move them around the main stems. For the beans that have not latched on yet, and next year's crop I will watch out and do this sooner. I removed two of the biggest corns and opened them up. The kernels were all perfectly formed, but still small. We had harvested a bit too early, but it tasted very nice. Will give the other corns more time.

As farmerdill said, the Early Sunglow is an early small plant, I expected the cobs to also be smaller, but did not know how small...slowly getting the hang of it.
