Since asparagus is a perennial vegetable, and can produce for up to 30-50 years, it is very important to prepare the soil properly (read: Introduction to Soil). The best soil is sandy, well drained loam, heavily enriched with well-rotted manure and compost (read: Getting Started - Introduction to Composting). Ground prepared in this way dries out quickly in early spring, to spur the early growth of the spears. The pH should be about 7.5. Average garden soil, however, will support a good asparagus crop, provided it drains well. How to Grow Organic Asparagus from Seed »
