- Young spears (shoots). Harvest time: collect asparagus spears in the early spring, while very young. Only collect spears from areas you know have NOT been treated with pesticides. Safe handling procedures: wash spears thoroughly with warm water to remove dirt and debris. Do not use dish detergent or any type of sanitizer. These products can leave a residue. Peel off the outer skin to within an inch of the top of the spear. Tie spears into bundles (about eight to a bundle) and place lengthwise into boiling salted water. Boil for about 10 minutes until tender, but not soggy. Serve hot with melted butter, or cold with oil and vinegar and seasonings.
