Can I plant my crowns in Early May or do I need to wait until the fall

If you take care to water and watch for pests like fire ants etc... You could actually put crowns in anytime in months that have workable soil in your proposed asparagus beds... they take a long time to harvest when you first put them in so I suggest getting them in ASAP if you have some waiting. They do quite well here in part shade (Pitt County, NC) and they are VERY forgiving and productive. We have the purple asparagus and it puts out shoots ongoing from early spring and sporadically though hot summer... mostly goes to fern mode in hot weather but still will make occasional shoots out of the norm. As long as you fan out the roots as much as possible and plant them properly they should be fine.

The start of spring.

I have a few asperagus plants in my garden, do I have to cut down the branches above the soil and when, for them to produce more.

Cut them down in late winter and then eat the new shoots in the spring time.

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.

Seeing as asparagus takes so long to be ready to harvest, can any one give a guide as to how much room to devote to them? We need enough for two. Any ideas?
