Hooray! I'm doing the same thing for the first time. My corn just came up last week -- I had started zucchini & black beans indoors and transplanted, then planted the corn.

Oh wow, we are doing the same thing; I did the corn first but the beans just grew faster/

Here's mine. You can see the corn is really small, but really it grew about 6 in in a week! The beans are growing fine, and the zucchini look like such happy healthy plants they do my heart good. There are eggshells all over. I crushed them this morning - tried to roast them last night but burnt them, and the smell was too bad to keep inside with the worm bin.
