(Best months for planting Asparagus in New Zealand - cool/mountain regions)
Seeds will take 2-3 years before maturing into crowns.Plant crowns (roots) 20-40cm apart and a few cm deep in well manured soil. Recommended soil pH 6.5 - 7.5 The asparagus shoots grow in spring. Harvest the shoots which are bigger than 1-2cm in diameter. Leave the rest to grow into the leafy ferns (1.5m 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 second or 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.
NOTE: The asparagus berries are poisonous.
Steaming is traditional, then coating with melted butter or hollandaise sauce.
Alternatively break in short lengths,
cook quickly in hot oil a wok and sprinkle with soy sauce or balsamic vinegar.
