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.

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.

If you live near a bigger town/city see if the company Nutrien Ag Solutions has a depot near you or call the Bundaberg depot. Ring them up and discuss it with them. Ask to talk to their agronomist. If you live near them take the leaves in to them. They are very helpful.

Hi all! I have just received my asparagus crowns. I’m concerned now that the bed I’ve chosen won’t be right for them. It gets full afternoon sun in summer and can get quite hot with no shade? Advice would be greatly appreciated :)

My plants are in full sun most of the day 6am to 6pm in summer, Bundaberg Qld. We had a lot of hot weather the last summer, had no problems. Give them a good watering each week if no rain in summer.

I am currently growing white asparagus and the plants are in their 3rd year. It is winter and the asparagus is giving me some large spears that I have harvested and eaten. I am leaving the smaller spears. Now that the smaller spears are growing into ferns, should I continue to cut the larger spears or should I leave them all to grow? Also I always thought asparagus was a spring crop, why am I getting such a crop?

Why a crop this time of year, probably because you have kept watering them. I did that establishing my asparagus the first two years. I'm sub-tropical and I stop watering mine the end of April, just the odd watering, not heavy, we have had very little rain since mid March. I actually cut my ferns yesterday, will not fertilise, compost and water until the end of August. I only eat my asparagus for about 5 weeks last year in the spring. But I cut my ferns off in Jan and had about 3-4 weeks of spears before letting them fern again. If the crown is biggish 9-12
