Today is 6/30 and the temp is dropping to 40 degrees tonight. I have tomatoes on the vine and first year asparagus babies just coming out ot the ground - should I be concerned?
You didn't say what the low would be. If it's not going to freeze, your plants will be all right. Your asparagus has a hardy root system, so if you got some cold kill, other shoots will soon sprout. You can cover tomatoes with old sheets if light frost is predicted, otherwise leave them be.
My friend gave me about 8 seeds and I want to start a patch with them. I live in Wisconsin and it is August right now. What's my best plan for getting these to grow?
If you're starting them indoors, you would normally do this about 2-3 months before your last expected frost date. Then once they reach 6-12 inches, you can plant them outdoors, treating them like you would crowns.

This past spring I planted Asparagus in a big pot and it grew well. I now have garden space and wish to transplant it. Can I remove the pot and place the dirt into my garden, or do I wait until spring and move the crowns only?
You should have enough time to do it now, but you have to do it ASAP, so that it has time to establish before it gets cold. If it does not establish before it gets cold, it cannot survive the winter.
If you are not certain that it will establish before the cold comes, it may be best to wait until spring to plant it in the ground.
I am wondering if I should cut dill down to ground for winter or just to approximately 6 inches from ground?
I also have mixed info on asparagus. Should it be trimmed to ground level or left tall and ferny till spring-then trim back?
Unfortunately, dill weed is considered an annual, though the seeds will usually overwinter in the soil. Therefore, it doesn't make much difference whether you cut it back to the ground or not. I would be sure to keep some seeds for next season should none of them pop up in spring, however.

I have 3 asparagus plants in medium sized pots. They have been in those pots for about a month and a half. Can I plant them in the ground now or is it too late in the season? I live in the southeast portion of Missouri. I could try to keep them indoors and alive until next spring if it would be best that way.
They can be planted now. We would recommend adding a layer of leaves or mulch over them for this first winter to help protect them a little more but other than that, planting them now will be fine.
I have asparagus that is a year old and 18" tall. When is best time to transplant?

I received my asparagus crowns in early Nov. and planted them a week before Thanksgiving. I just noticed sprouts coming up and we are having frost every morning. Should I be covering these sprouts? I live in NC, so weather can still get warm during the day, but frost by morning.
We would recommend adding a layer of leaves or mulch over them for winter.
