P = Plant in the garden.

August: frost tender

  • Easy to grow. Plant as crowns. Best planted at soil temperatures between 16°C and 30°C. (Show °F/in)
  • Space plants: 20 - 40 cm apart
  • Harvest in 2-3 years. Plant 'crowns' to harvest earlier .
  • Compatible with (can grow in same bed): Parsley, Basil, Nasturtiums, Lettuce
  • Avoid growing in same bed: Garlic, Onions, and root vegetables
  • Seedlings (approx 6cm/3in)
    Seedlings (approx 6cm/3in)

Plant crowns (roots) 20-40cm 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 1-2cm/half-inch in diameter. Leave the rest to grow into the leafy ferns (1.5m/5-6ft 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.

Which is correct, that male asparagus spears are fatter than female ones or the other way about? Thank you.

Hi Ruth, If you are still looking at asparagus crowns, The Diggers Club in Dromana has them. We were there last weekend and they had 3 varieties of crowns- Fat Bastard, Purple and Mary Washington. They do post also. Carly

I was given some asparagus ferns by our neighbour some months ago and want to plant them in the garden. They are about 8 inches tall. Can i plant them now? What are the soil requirements?

Plant August - Oct. Probably later in the cooler climates. For soil I used 1/3 good loam/ red soil - 1/3 composted grass clippings and 1/3 horse manure. A couple of good handfuls of general garden fertilizer every 6 weeks until Feb. I have three plants in a box 5' x 2'. My crowns grew from 1 1/2" to approx. 10" in the first year. They started shooting new stalks a week ago. Weather has been quite warm 23-25c.

Bought a punnet of Asparagus ferns a year ago and transplanted them in the ground but did not space them enough. They are still a few inches tall. When is the best time time to dig them out to re-plant? Any advice would be greatly appreciated. Thanks in advance.

Live in Sydney, like you bought a punnet and transfered to a larger pot for few months. Transfered them in mid autumn with lots of manure. They have been madly throwing ferns, once ferns die down, will re=manure and top dress with cow poo dressing as well. Hope this helps.
