Asparagus asparagus Asparagus is a long-lived perennial vegetable valued for its early spring harvest. Once established, a well-maintained bed can remain productive for 15–25 years or longer. Plants grow from underground crowns that send up edible spears in spring and tall fern-like foliage in summer, which replenishes the root system for future harvests. Growing conditions LightFull sun is essential for strong spear production and healthy fern growth. Asparagus tolerates light shade but yields decrease significantly without at least 6–8 hours of direct sunlight. Soil typeDeep, well-drained loam or sandy loam with high organic matter. Asparagus is very sensitive to waterlogging and compacted soils; raised beds or ridges are recommended on heavy soils. Water requirementMedium. Consistent moisture is especially important during spear emergence in spring and during fern growth in early summer. Drought stress reduces future yields. Nutrient requirementMedium to high. Asparagus benefits from steady nutrient availability over many years rather than heavy feeding at once. Back to plant list
