P = Plant crowns

  • 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 beside): Parsley, Basil, Nasturtiums, Lettuce
  • Avoid growing close to: Garlic, Onions, and root vegetables
  • Asparagus growing
  • Baby Asparagus Seedlings (approx 6cm/3in) ((c) Liz Hutchinson)

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.

You can buy seeds and crowns (depending on the season) from Livingseeds in Midvaal. They have a online website with plenty of organic heirloom seeds.

I do not have access to crowns but do for seeds. How best to prepare the soil and what pH is recommended?

Bunnings sell crowns this time of year. Google seed selling companies on the net - like Eden seeds or similar. Crowns will have you 12 mths ahead of seeds. Just good friable soil ph 6-7 will grow most things or google it.

Google how to grow it. Late winter you need to cut it off at ground level. Put compost 4-6 cm.

I will be digging up crowns from an elderly friend's garden. They have been growing, as in, multiplying, over the years and now too many in the bed. I'm guessing to lift them in late winter (subtropics), however, I am not sure. The lifted crowns will then be shared by other people, so, are there any good instructions for re planting the crowns, when etc, please? Thank you very much and also thank you for your monthly email for planting, I have told so many people about your list. Wendy Strathearn Gympie Permaculture

Do it late August. Have your soil well prepared with compost and manures. Plant the crowns and water each week. A really good watering the first time or before you plant them.

Dig up late winter - mid August, break into required pieces and plant into soil with plenty of compost in the soil, Mix in some Rooster Booster from Bunnings or something similar and water regularly - 2-3 times a week. You may not have a big harvest the first year or so, depends on the size of the crown you plant.

Check around your area what varieties are grown - internet, nurseries, stores that sell seeds and bulbs.
