Have them come up yet? I remember mine were slow the second season. They're on year six or so now and I've been harvesting for a month now.

Hi. Just wondering if my asparagus from last year shouldn't be up (visible) by now... It grew successfully last year from seed, (had 2 foot ferns) and even one or two edible stalks..(First year) Expected them to be great this season, but...I'm worried as there is no sign of them... Hope they didn't die... How can I check? I'm in zone 5. Nova Scotia. Its been a cold spring up until this week. Do you think they are dead?

My asparagus came up a few weeks ago. I was told that you shouldn’t eat asparagus until the 3rd season. Then only cut off the ones that are thicker and cut it close to the ground.

I actually live in Costa Rica, but it's not on your list. I'm at 1000 meters, distinct dry season Jan thru May, no rain at all with temps around 28-30 degrees. I need to move my 3-4 yr old crowns - can I do it anytime or would it be best to let them dry out a little to aid dormancy then move them once the rains start end of May. THANKS FOR THE HELP!

I have quite a high content of clay in my soil, even though I add a bit of Lime,and drainage 150mm under the clay and compost mixed, Will the asparagus enjoy this type of Soil? Also how can one determine the ph of ones soil?

I'm still confused about planting out: I've dug the trenches and planted the seedlings ( each having a feathery top and miniature spears) but do I now mound the well composted soil over the top of same or do I wait until they have grown some? If the latter, for how long? I'm not trying for the blanched (or white asparagus) .. just the green. Many thanks!

Hi Delia, I am a first time grower of A, have bought crowns this year, and seedling last year. And also planted seeds this year too. I guess you would treat it like any seedling, cover the roots up towhere the green freathery top starts, and leave any mini spears out in the air too. I read that one should not harvest any spears for at least a year from crowns or 2 years from seeds, so let any spars that you may have go and change into the fern this year. I believe it has something to do with strength going into the crown for next year, then you can cut some but not all..... good luck, I think A is something of a future investment, for patient people.....
