Go to New Zealand subtropical asparagus and the info is there when to plant. Bunnings generally have them in August to plant. Or internet seed selling website.

my asparagus plant is on its 3rd season since being transplanted...this winter the ferns appear to have died. there's 3ferns left and I've supported them. What I'm asking is it looks dead...any advice??

Depends how much water you have put on over the last 2-3 months. The plant goes into dormancy in winter and the ferns die back later autumn/winter. Wait until late August and give it some fertiliser, put 100mm of compost on top and start watering it. It should start sending up spears after that. If not it might be dead. Google about growing asparagus.

The ferns do die, asparagus will send shoots up in warmer weather aka springtime, it's like strawberries, dies down over winter but roots are still alive and come back in springtime :-)

Heads are just coming up but are being eaten by something very small that is killing each head off or leaving scars. Put some chook manure on a couple of months ago and wonder if its bugs in that? Any help would be great.

Google it - bugs that eat asparagus. Probably have to go out at night to see them. Then look for a spray, organic or chemical. Maybe don't use chook manure, or compost it before putting it on. I don't put compost/manure on until mid-late August.

Can you grow asparagus in a bathtub and how many plants could you fit in? Many thanks.
