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.

I bought asparagus seeds, F2 UC172 I sowed the seeds in spring and have a lot of very fine feathery plants, they starting to make shoots that looks like spears, what do I do now? Will they mature, or do I have to cut the and spears and re plant them? I live on a farm in Grahamstown

Leave the plants to grow & mature for another 2-3 years. You can trim back the ferns (to 5cm) either in the fall after they turn brown or at the beginning of spring.

Try the internet, ask around at nurseries or Bunnings.

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

When do you cut off the ferns and how low do you cut them?

Late winter and at ground level or just below. Then cover them with about 4-6 cm mulch.
