Asparagus prefers soils that are slightly acidic with a pH of 6.0-6.5. Sandy soils are best, as they allow for better drainage. It is also important to choose a location that is free from weeds, as these can compete with asparagus for nutrients and water. The area should also be free from pests and diseases.
Step 2. Choose The Right Variety
Choosing the right variety is an important step in growing asparagus. The quality of the seed chosen will impact the quantity of yield during harvest. That is why you need to carefully choose the right variety.
Asparagus is a perennial vegetable, so you need to choose a variety that is suitable for the climate in South Africa. The most popular varieties grown in South Africa are Jersey Giant, Mary Washington, and Purple Passion.

It is important to amend the soil with plenty of organic matter, such as compost or aged manure, to improve its fertility and drainage. Create a 3-4-inch-deep furrow in the soil.
Step 4: Plant Asparagus Crown
After the soil has been prepared, you should Plant the crowns (the root structure of the asparagus plants) in the furrow, spacing them 18-24 inches apart. Water the plant immediately after planting.
Step 5. Water
Asparagus needs plenty of water, especially during the growing season. Make sure fir the first two weeks after planting, water the plant regularly. Once established, asparagus does not require frequent watering. Water deeply and regularly, especially during dry periods.
Step 6. Fertilize
Asparagus requires regular fertilization to stay healthy and productive. Use a balanced fertilizer and apply it twice per year: once in spring and once in fall.
Step 7. Mulch

How To Grow Asparagus From Seedlings
Asparagus is a perennial vegetable that can be grown from seedlings or from seed and can be harvested for up to 20 years. Growing asparagus from seedlings is easier than growing it from seed, and it will produce a harvest sooner.
- Start the seedlings in a pot indoors in late winter, about 8-10 weeks before the last frost. Plant the seedlings in a pot that is at least 8 inches deep and filled with high-quality, well-draining potting soil.
- Place the pot in a location that gets plenty of sunlight, such as a sunny windowsill.
- Once the seedlings are about 6 inches tall, begin to harden them off. This means exposing them to sunlight and wind for a few hours a day for a week, increasing the time over the course of the week.
- Plant the seedlings in the garden in late spring, after all danger of frost has passed. Dig a 4-inch deep trench, and place the seedlings 12 inches apart in the trench. Cover them with soil and water them in.
- Provide the asparagus plants with 1-2 inches of water per week. As the plants grow, cover the spears with soil to blanch them.
- Begin harvesting the spears in the spring of the second year, when they are at least 8 inches tall. Cut the spears at the soil line and discard any that are less than 1/4 inch thick. Continue to harvest for up to 8 weeks.
Fully Grown Asparagus Plant
Fully-grown asparagus plants are perennial vegetables that produce spears for up to 20 years. Fully grown asparagus require rich, well-drained soil and full sun. Asparagus can be harvested in the spring and fall, and should be cut near the soil line when the spears are thick and firm.
How To Grow Asparagus From Seed In South Africa
To grow asparagus from seed in South Africa, choose a sunny location with well-drained soil and lots of organic matter. Sow seeds directly in the garden in late summer to early autumn. Make sure the soil is at least 20°C and keep moist until germination.
Thinly spread the seeds, cover lightly with soil and keep moist until the seedlings emerge. Transplant the seedlings to their permanent position when they are 15 cm tall. Keep the soil moist and weed-free.
Harvest spears in spring for the first two years, then leave the spears to fern out for the following years.
