Asparagus is an early-harvested plant in the lily family. It is grown from crowns that are typically planted in sandy soil. Asparagus is a fast-growing plant that can grow up to 10 inches in one day. Such a fast-growing plant is an excellent companion for planting near shrubbery and hedges. Once the harvesting season has ended, keep your crowns in the ground as they will produce small ferns with red berries, which can be replanted the next year.
Measure the desired beds, spacing the asparagus at least 5 feet away from the hedges in every direction. If you are planting more than one crown, then also measure out 18 inches between crowns. Mark the acceptable locations with marking chalk.
Test the soil in the area of the yard where the asparagus will be planted. Asparagus thrives in pH-neutral soil (7.0). If the soil is more or less than 7, consult your local county extension office about acceptable soil additives to change the overall pH.
Mix some compost into the soil to a depth of 8 inches to provide the crowns with adequate nutrients for growth.
Dig a hole roughly 4 to 6 inches deep and place the crowns inside. The roots should face downward.
Fertilize the asparagus monthly during their growing season and once more at the end of the season before the plants go dormant.
