Will female asparagus plants produce quality spears? Is it possible to distinguish femaie and male crowns?

Do asparagus do well if I was to start them as a seedling in a greenhouse?
26 Aug 13, Norm (Australia - temperate climate)
Yes Jessica, asparagus grow well from seedling even when not in a greenhouse. It does take much longer to produce edible spears this way . Using crowns, at least 3 years old, would be quicker but more expensive.

I am moving house and, having carefully nurtured my asparagus seedlings through to maturity, want to take my crowns with me. Any tips on digging up, transporting and replanting? Do I have to wait 2 years before harvesting again?

I planted several crowns last season and let them grow into ferns. It is now July, and many of the ferns have not died down yet, but more questionable is the fact that several of the plants have sprouted new spears. Is this normal? Is it a sign of a mild winter? Should I just be letting these spears grow into ferns - they are a healthy size, big enough to harvest...

I understand Rupert, my asparagus is the same. It hasn't realised it is winter. I ate a spear; it was crispy but lacked flavour.

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'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.....

Thank you Jen: your suggestions are most welcome and these suggestions are exactly what I did. I have a half dozen tiny spears popping through and, while not wishing my life away, I can barely wait the two years required. I also understand that a lightly wooded Chardonnay is the perfect wine match with asparagus. Thanks for sharing, Delia
