a bit hard to stop watering in Perth at this time I might knock it down at the end of summer and try to pick a few late spears then

Cut back the watering from end of May. If you keep watering and have a warmish winter it keeps growing. The idea is for the plant to put a lot of energy etc back into the crown (from the ferns) mid summer to Autumn. That is what allows the plant to send up spears during Spring. This time of the year you should have the ferns cut off, put 100-150 (?) of compost on top and applied some fertiliser and be watering heaps. At the moment I'm picking 12-15 spears each third day from 4 crowns.

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.

It might be slugs or snails, try using something to kill or deter them.

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.

I purchased some purple asparagus seedlings 1 year ago (Aug 19) Perth WA Planted them out Dec 19. 1 large female bush is still growing spears up to 15mm thick in July 20 and shows no signs of weakening. I have resisted the temptation to eat the spears, but with spring approaching I am wondering if I should prune it or just leave it to the ravages of climate change. Needless to say I am collecting the berries. Michael

A suggestion, stop watering asparagus at the end of May, let the ferns die off. Then around now to early September, cut all the ferns off at ground level. Scatter some fertiliser on the top of the soil and put 150mm of compost/manures etc on top of that. Start water again.

We live on the Edge of the Great Swamp, near Koo Wee Rup in Victoria, where most of Australia's asparagus is grown. The plants are in full sun constantly, and in peaty soil which is constantly wet. You should be fine.
