Growing asparagus in Australia requires patience, but the reward of fresh asparagus spears for many years makes it worthwhile. The best time to plant asparagus crowns is between August and November, allowing them to establish themselves before the growing season in spring. Asparagus grown from seeds can be sown in spring, but it will take at least three years to reach harvest. Asparagus thrives in a sunny, well-drained spot with soil enriched with compost and manure. It is a long-lived crop, producing delicious spears for up to 20 years, so it's important to allocate a dedicated space in your garden.

Best time to plant asparagus crowns: late winter to spring
Asparagus is a long-lived crop, so it's important to prepare the soil well before planting. In Australia, the best time to plant asparagus crowns is between late winter and the end of spring, from August to November. This allows the crowns to establish themselves before the growing season begins in spring.
To prepare the soil, add a soil improver and plant fertiliser. Dig a trench that's about 20 cm deep and 30–40 cm wide, with a mounded ridge at the bottom. Space the crowns 30–50 cm apart along the trench base, placing each one on its own mound of soil so the roots can spread out. Cover the crowns with 5–8 cm of soil and water well. As the trench fills in with soil as the shoots grow, mulch with a thick layer of organic matter, such as compost mixed with dried grass clippings.
Asparagus crowns are typically sold bare-rooted in winter, ready for planting. As the crowns are already a few years old, they establish quickly and will be ready to harvest after two years. It's important to leave the asparagus spears on the plant for the first couple of years to allow the crown to establish in the soil.
Asparagus loves well-drained soil and plenty of sun, so choose a sunny, well-drained spot in your garden. Make sure the planting site gets at least seven hours of direct sunlight daily and is protected from strong winds.

Preparing the soil: well-drained, enriched with compost and manure
When it comes to growing asparagus in Australia, preparing the soil is a crucial step that significantly impacts the health and productivity of your asparagus crop. The ideal soil for asparagus should be well-drained and enriched with compost and manure, providing the necessary nutrients and ensuring optimal drainage for healthy plant growth. Here's a detailed guide to help you prepare your soil effectively:
Creating Well-Drained Soil:
Asparagus performs best in well-drained soil that doesn't allow water to pool around the roots. If your garden tends to have heavy, clay-like soil that drains slowly, consider building raised beds or You may want to see also In Australia, the best time to plant asparagus crowns is between August and November, during late winter through to the end of spring. This gives the crowns time to establish themselves before the growing season begins in spring. To begin planting your asparagus crowns, start by digging a trench. The trench should be about 20-30cm deep and 30-40cm wide, with a mounded ridge at the bottom. Space the crowns along the base of the trench, leaving about 30-50cm of space between them. Before planting, soak the crowns in water for 15-30 minutes to moisten the roots. You can also use a manure tea for added nutrients. Next, cover the crowns with 5-8cm of soil. It is important that the crowns do not dry out during this process, so water them immediately after planting. As the shoots grow, continue to backfill the trench with soil. When the trench is full, add a thick layer of organic matter, such as compost mixed with dried grass clippings, to mulch the bed. Water and feed your asparagus regularly with a liquid plant food. Your asparagus plants will need consistent soil moisture to stay healthy, so make sure they receive at least one inch of water every week. If they have not received an inch of rain in a week, be sure to soak the soil with water. You may want to see also Growing asparagus from seeds is a long-term commitment, but the reward of fresh asparagus spears for many years can make it worthwhile. In Australia, the best time to sow asparagus seeds is in spring, and you can expect to harvest your asparagus after 3-4 years. Asparagus seeds can take between 2 to 8 weeks to develop into seedlings. Once the seedlings are about 10-15 cm tall and the danger of frost has passed, they can be transplanted outdoors. This is usually done in late spring or early summer in Australia. Before transplanting, prepare your soil by ensuring it is moist, and add well-composted manure to boost asparagus growth. Dig trenches in your garden bed about 20 cm deep and 30-40 cm apart. Place the seedlings at the bottom of the trench, spacing them about 40-50 cm apart. Cover your asparagus seedlings with 5-8 cm of soil and water well. Asparagus grown from seeds will not be ready to harvest for at least 3-4 years. This allows the plants to develop a strong root system. During this time, it is important to leave the asparagus spears on the plant to allow time for the plant to establish itself in the soil. Once your asparagus has been established for 2 years, you should begin the yearly task of cutting back the fronds each winter. After the edible asparagus spears finish in summer, allow the tall green fronds to grow and brown off throughout autumn. Cut these fronds off at ground level in winter, and fertilise the area. Asparagus is a perennial plant that is easy to grow and, once established, will continue to produce for 15-20 years. It is important to allocate a separate bed for your asparagus, where it will not be disturbed by short-lived annual crops. Asparagus does best in a sunny position, preferably free from strong winds, in rich, well-drained soil that has lots of organic matter added to it. You may want to see also Asparagus is a perennial flowering plant that can produce delicious crops for 15 to 20 years or more, so it's worth investing your time in this vegetable. It is quite easy to grow and, when established, is fairly low maintenance. However, it requires patience and a little extra care to get started. Cut Back in Late Autumn As part of the life cycle of the asparagus plant, foliage begins to die back, turning yellow or brown as crowns go dormant. At this time, cut them back for winter. First, allowing plants to complete their seasonal life cycle will produce healthier roots. Second, roots that form to support the growth of new foliage are stronger and deeper. Healthy roots produce healthier plants and a more bountiful crop in the next growing season. Once you have cut the asparagus back, add several inches (about 10 cm) of mulch to your asparagus bed. This will help to smother the weeds in the bed and will help fertilise the bed for next year. Compost or well-rotted manure makes excellent mulch for asparagus in autumn. Fertilise in Late Winter/Spring Asparagus plants naturally die down in winter, but they will reappear in spring. Remove and compost the dead ferns in autumn and feed in late winter or early spring with a soil improver and plant fertiliser. Planting The best time to plant asparagus crowns in Australia is between August and November, late winter through the end of spring. This allows the crowns to establish themselves before the growing season begins in spring. Meanwhile, spring is the best time for asparagus seeds or until frost has passed.

Asparagus grown from seeds can take between 2 to 8 weeks to develop into seedlings, which then take about 3 to 4 years to reach harvest. Asparagus grown from crowns or cuttings can take 2 years to mature. Asparagus is easy to grow but requires patience. It is typically grown from bare-rooted crowns in winter. Prepare the soil by adding compost and decomposed manure. Dig trenches in your garden bed about 20 cm deep and 30-40 cm apart. Place the seedlings at the bottom of the trench, spacing them about 40-50 cm apart. Cover your asparagus seedlings with 5-8 cm of soil and water well.E-Cigarettes: Australia's Ban Debate
