Don't really know what you mean by "come in" but if you have plants they should be fine -- even planted in late October. Make sure they are firmly planted and watered in well, and it would not hurt to cover with a winter mulch-leaves or straw.

Thanks,

Referring to seed that was directly sown last November and just recently germinated between this late August and September. Could the roots be grown deep enough? Our ground hasn't frozen yet but won't be before too long.
