I was planning on planting asparagus between my grape vines which are new and will be I’m hoping on wires 4 ft above ground. Would the ferns be too high to grow without shading out the grapes?

I would suggest you don't. Asparagus need their own area to grow in "full sunlight". They will be there for 20+ years and they spread a bit as the crown grows. You pick the new asparagus shoots (they need full sun then) for about 10-12 weeks and then let the ferns grow (they reach about 4').

I live in Midland, 50 miles north of our largest harvesting area Allison. Asparagus is my favourite vegetable but Ontario seems to have a season of only a month or so. How does asparagus from Mexico or Peru be available year round? If asparagus was planted in northern Ontario—such as in the agricultural belt near New Liskeard—would our harvesting time be correspondingly extended?

Can I still plant crowns in March? What varieties are suggested for my area? Florida zoom 10. Can I plant them in the ground or would a grow bag be better?

I planted crowns last year in a raised bed. As of today, March 2nd, I have a lot of spears and ferns that are 3-4 feet high. Do I continue to let them grow or cut it all down at the soil level? Can’t seem to find the right answer.

You must be south of me. I'm in Bastrop. My "ferns" (not sure what to call those) are over 5 feet tall now! I'm going to let them grow now until they die out when it freezes. I got one spear the first year!

Zone 8b, Central Georgia. Since we have pretty hot, scorching summers, would it be better to plant asparagus where it doesn't get full afternoon sun? Just afraid it couldn't take the heat.
