Asparagus Seeds FAQs

Take a look at some of the frequently asked questions we receive from those looking to buy Asparagus Seeds in the UK. You can contact our Customer Service Team or browse our general FAQs for further advice.

When to Plant Asparagus Seeds

Asparagus seeds should be sown indoors in early spring, typically between February and April. This gives the seedlings ample time to develop before being transplanted outdoors later in the year. For those in warmer climates, direct sowing outdoors can be done in April or May once the soil has warmed up and all risk of frost has passed.

How to Grow Asparagus from Seed

To grow asparagus from seed, begin by filling seed trays or pots with a high-quality seed compost. Sow the seeds about 1cm deep, spacing them evenly, and cover lightly with compost. Place the trays in a warm, bright location with a temperature of around 20°C, and keep the compost moist but not waterlogged. Germination can take 2 to 4 weeks. Once the seedlings have developed a few true leaves and are large enough to handle, transplant them into individual pots or directly into a prepared garden bed, spacing them 30cm apart. Asparagus requires well-drained, fertile soil and full sun to thrive. The seedlings can be transplanted into their final position in the garden the following spring.

How Long Does It Take to Harvest Asparagus?

Growing asparagus from seed is a long-term investment, as it typically takes about three years before you can start harvesting a significant crop. In the first two years, the plants will be focused on establishing strong root systems. By the third year, you can begin to harvest a small amount of spears, and by the fourth year, the plants should be fully established, allowing for a more substantial harvest each spring. Once established, an asparagus bed can produce for up to 15 years or more, offering a reliable source of fresh asparagus spears each season.

Why Grow Asparagus from Seed?

Growing asparagus from seed has several benefits. It allows you to select from a broader range of varieties, including heirlooms and other types that may not be available as crowns. Starting from seed is also more cost-effective, particularly if you want to establish a large asparagus bed. Additionally, growing from seed allows the plants to adapt to your specific garden conditions from the start, often resulting in healthier, more vigorous plants that are better suited to your soil and climate. Although it requires patience, the long-term rewards of a thriving asparagus bed make the effort worthwhile.

Where Can You Grow Asparagus?

Asparagus is best grown in a dedicated bed with full sun and well-drained, fertile soil. The bed should be prepared in advance with plenty of organic matter, such as compost or well-rotted manure, to ensure the soil is rich and loose. Asparagus can also be grown in raised beds or large containers, provided they have sufficient depth to accommodate the plants' extensive root systems. A sunny location is essential for the best growth and productivity, and asparagus plants prefer a spot where they won’t be disturbed, as they can remain productive for many years.
