In cooler climates asparagus normally yellows and dies back in the winter as you say. in the spring if the spears are left they will grow on to form the big ferny tops that we are familiar with. The plant uses these tops along with manure or compost to regenerate the roots in readiness for next springs crop. You could try bending these over so they are bruised and nearly broken off to force the plant into dormancy. If you cut them off the plant may just send up some more spindly spears.

Can I grow asparagus down in the cape, near Hermanus. Also where down in that area can I purchase crowns. many thanks

Asparagus is a very hardy plant and you should have no difficulty growing it. Try googling 'Asparagus crowns in South Africa" and you will find a number of suppliers. Asparagus crowns are often available from nurseries, garden centres, hardware stores and online during the winter.

Keep the seeds in a cool dry place. I kept watering my asparagus all the way into July last year - spears kept coming up. When I did cut them in August, new spears appeared in week or so. I gave my 3 plants a big hair cut a week ago. I have 4 x 6' posts at the corners of the garden bed and cord running around the post to support the ferns. The ferns grow to 6-8' high. I only cut spears for 1 month last year (2 yr old plant). In hindsight I could have cut them for another 4-6 weeks. The crowns are now about 15" in diameter (2.5 yrs old now). The little seedlings I planted out in Sept are still growing - the shade cloth cover did the trick. The last 2.5 mths have seen the temp in the 32-34 degree area (3 d above average). Have grown quite well in this rather hot weather. Looking forward to August - November to having a great feed off them.

All my asparagus grew really well in April especially the new little plants (6) from seed planted Sept last year. Although I keep trimming the older plants back they just keep growing - the warm weather - 26 C here today and nights 14-16 C. Looks like another warm winter coming.

Can I gather the berries now in Autumn and keep them to sow in Spring? Should I keep the seeds cool?

There's no reason not too. Mother Nature does it! Plant them in a row about 75 mm (3") sapart and separate them the following winter for planting in their permanent position. All the best.

Where can I purchase a Ming fern plant in Melbourne
18 Feb 17, John (Australia - temperate climate)
Ming Fern (asparagus) seed is listed on ebay. It is fairly easy to grow from seed. If you search for it on the internet you will find nurseries that have it in Melbourne. It is listed as an environmental weed in NSW and can't be purchased in that state. Trust this helps

I have just bought a house in southeastern SA and it has a large raised asparagus bed. The ferns are over a metre tall and mostly still green, do I cut them back to ground level when they yellow or just leave them till they fall naturally, also, should I water them or not? I believe the asparagus is about 5 years old.
