How to Grow Asparagus

If there's one vegie worth investing your time in, Asparagus is it – literally! It can take up to 2 years for your crop to be productive, but the wait is well worth it. All you need to do is to prep the soil well, give it basic care and this will ensure it will produce delicious and crunchy spears for fifteen years or more! Asparagus can be grown from seed, but it is typically grown bare rooted crowns (aka bunch of fleshy roots) in winter.

Full sun or part shade

Regular watering

Well drained

Suitable for all climatic zones.

Harvest by gently cutting spears when they are around the width of a pencil.

How to grow asparagus in a garden

Step 1

Prepare the soil by adding in Yates Dynamic Lifter Soil Improver & Plant Fertiliser.

Step 2

Seedlings should be two years old before planting out in their permanent position.

Step 3

Asparagus has male and female plants – males grow bigger and produce better spears so female plants, which grow red berries, should be discarded.

Step 1

Prepare the soil by adding in Yates Dynamic Lifter Soil Improver & Plant Fertiliser.

Step 2

Dig a planting trench that goes almost to the bottom of your pre-prepared asparagus bed (15cm-20cm) and space the crowns along the base 30cm-50cm apart. Spread each clump over its own little mound of soil, and cover lightly.

Step 3

Backfill trench with soil as the shoots grow.

Step 4

When the trench is full, mulch with a thick layer of organic matter (e.g. compost mixed with dried grass clippings).

Step 5

Water and feed regularly with Yates Thrive Natural Vegie and Herb Liquid Plant Food.

Growing tips

As plants grow, they develop leafy fronds, which capture energy from the sun for the spears to grow. They will naturally die down in winter, but don't worry, they will unfailingly re-appear each spring. Remove and compost the dead ferns in autumn and feed in late winter or early spring with Yates Dynamic Lifter Soil Improver & Plant Fertiliser. Renew the layer of mulch each year.
Small spears will appear in the first year, but we recommend pruning them so the plant doesn't waste energy into producing them. Your first proper harvest will be the second growing season. Feed regularly during the warmer months with Yates Thrive Vegie and Herb Liquid Plant Food.
