  • Easy to grow. Plant as crowns between August to November. Best planted at soil temperatures between 16°C and 30°C.
  • 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

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.

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

Asparagus..you mention to plant crowns. Best to plant seeds as commercial growers tend to get rid of all their female thin asparagus crowns and just keep the fat males. Female asparagus are good for salads. Females have the red berries.
