But once the plants have got established, you can harvest it sustainably as asparagus beds can be productive for 15, 20, sometimes up to 30 years!

You also don’t have to worry about the produce. Asparagus plants are fairly fast producers, sending up new spears every few days for a few weeks in the spring. The plant produces ½ pound of spears per foot of row in spring and early summer, so you can harvest often!

If it’s your first time growing asparagus, you can start with 5 to 10 asparagus plants (15 to 30 feet of row). To learn how to grow asparagus, make sure you start at the right time. Start seeds indoors mid-February to May under bright lights. Soil temperature for germination: 21–30ºC (70–85ºF). Planting asparagus is like a long-time investment, so you’ll want to plant the best variety available for your area.

Start by soaking the asparagus seeds for 2 hours. Plant 1 seed per 5cm (2″) pot, 1cm (½”) deep, keeping in a warm place. They can take 2-8 weeks to sprout depending on soil temperature, so you can start transplanting when the seedlings are 10-12 weeks old and danger of frost has passed. 

Space 45cm (18″) apart in rows 1-2m (3-6′) apart, then place each plant in a hole 10cm (4:) deep and gradually cover the crown with soil as it grows. For thicker spears, space 30-35cm (12-14″) apart and set buds 15-20cm (6-8″) in the hole. For thinner spears, space 20-25cm (8-10″) with the buds 10cm (4″) deep.

Fertilize after harvest and again in the spring with 1-2 cups of complete organic fertilizer per 3m (10′) of row, worked in lightly. Asparagus needs 2cm (1″) of water per week. In late fall, trim ferns down to 5cm (2″) and dispose of cuttings to avoid future disease and insect problems.

Once the plants have become established and strong, at the third year you can start harvest over a 2 week period. Cut the fattest spears off at ground level when they are 15-20cm (6-10″) long. When thinner spears begin to emerge let them to grow into big fronds to nourish the roots. You can then harvest for three weeks the next year, and four to six weeks after that.

You can also learn how to grow asparagus from cuttings. When production of spears slows down over several years, it is time to cut the root into pieces. 

First, dig up the root in late fall after the last ferns have died back. Cut it into several pieces, each with plenty of healthy root attached. Replant them then or wait until spring after the last frost. If you chose the latter, make sure to store the roots in a mesh or paper bag filled with sawdust. Roots from asparagus crown division will need another year to establish and produce spears.

Before planting a new asparagus bed, make sure to get rid of all the weeds and grasses from the planting area—even if this requires a full year of advance preparation. Asparagus plants will not tolerate weed competition, so you need to especially pay attention to this right from the start.

Also, remember to not be greedy when it comes to harvesting the crop. Pick too much, and your plants will not be able to develop the strong root system and energy reserves they'll need to produce an abundant crop of spears the following season.
