  • Baby Asparagus Seedlings (approx 6cm/3in) ((c) Liz Hutchinson)

Plant crowns (roots) 20 - 40 cm apart and a few cm (1 inch) deep in well manured soil. The asparagus shoots grow in spring. Harvest the shoots which are bigger than 1 - 2 cm/half-inch in diameter. Leave the rest to grow into the leafy ferns (1.5 m/5 - 6 ft tall) which will feed the crowns to give a crop next year. In autumn the ferns will be covered in bright red poisonous berries.

Leave the ferns to die down in autumn, then trim off the dead stalks and pile on plenty of rotted manure/compost to give the roots plenty of food to produce new stems in spring.

Harvest by cutting off the stalk, close to the ground. From the third year you can get an additional crop by letting the first lot of ferns grow, then bending down the stalks to break them. A second crop of shoots will grow and can be harvested. Leave subsequent shoots to grow on to ferns. Asparagus does not like continuously wet and warm soil. It grows better where there is a cool or frosty season.

Culinary hints - cooking and eating Asparagus

Steaming is traditional, then coating with melted butter or hollandaise sauce.
Alternatively break in short lengths, and cook quickly in hot oil in a wok and sprinkle with soy sauce or balsamic vinegar.

NOTE: The asparagus berries are poisonous. Only the young shoots are edible.

Planted Mary Washington 6yrs ago (from Bunnings). Is a female plant. Producing thin stalks. Where in Australia can I buy a male asparagus plant. As far as I know, males are used for commercial crops. So far, even nurserymen can't help. Anyone?

Bunnings sell asparagus this time of the year. I'm no expert but I don't think you can tell until the have grown for a year or so.

Try Bunnings - they usually sell this time of the year. Buy 3-6 crowns. One plant won't supply enough spears.

What is the best variety to grow in Katherine, NT? I have never grown asparagus before.

Whatever you can buy - green or purple.

Have been away and have come home and asparagus is already up, do I cut if and start again or just harvest what comes up?

You can cut all the shoots/fern off. Any that are just spears you can eat. Cut them off each day or two. Enjoy!!!!!

I planted a few asparagus plants in a small raised bed. The bed now looks very full. What do I do for over crowding?

Thin out weaker plants and provide adequate spacing between the remaining ones. You can also transplant or divide the crowns.
