I want to relocate 3 of mine. I have read they don't like it and you might miss a season's crop. Also if a few years old they may be quite large as in 450-700mm deep. Best time would be in mid winter probably.

Hi all, our asparagus ferns are still green.We're in Gisborne Vic.Should we wait till they turn completely brown or can we trim them off now.Will it make any difference to the crowns if cut them now while they're still green .Thanks Tony

I'm no expert - I have been growing them for 3 yrs. The new spears shoot in early Spring. So do not trim them now. I made the mistake of cutting them in late July last year and I had a very poor crop. My advise is to water them until the end of this month and then no watering. Let the plant die off. Then in late August cut the dead stalks off and put on the composted manure or just some good compost.

Try the internet, ask around at nurseries or Bunnings.

Crowns/plants don't usually become available until mid/late winter.

Just bought a property with what was told is asparagras. seems to be all fern its Febuary. From what i hv read in previous posts you let the fern dye down & fertilize but when does it come back to harvest ?

Cut it back late winter and put compost/manure on it. Spears will start coming out in Sept. Pick spears until Nov and then let it go to fern again to let the plant build up for the following season.

I have just raised asparagus (Fat Bastard) from seed . I have two plants per 4 inch pot planted in November 2017 & seedlings 4-6inches high. Should I plant these out to permanent garden beds now or continue to raise them in pots till next season? Locality is Berwick Victoria.. Graham

I live near Bundaberg Qld and it was a real struggle to grow from seed last year. Temp was 2-3 degree above normal. I had 6 survive out of about 30 in the garden so I would suggest you keep growing them in pots. Maybe put into bigger pots and push them along a bit with fert and water.
