How to Grow Asparagus in a Container Garden

Asparagus is a slow-growing vegetable popular with gardeners and chefs around the world. The plant produces thin edible stems with bulbous tops. These are sometimes called asparagus spears. The best time to plant asparagus is around early to mid- spring, depending on your location. Asparagus can be grown in home gardens and will produce spears in containers or large plant pots.

Instructions

1

Select a large plant pot or container for your asparagus. Choose pots at least 20 inches wide, with a depth of 20 inches, according to Container Growing Tips. Ideal containers are up to 6 feet by 6 feet. Decide how much space you have in your garden before choosing a container. Ensure your container has several drainage holes in the base.

2

Fill the container or pot with compost or potting soil. Use soil with a pH of between 6.5 and 7.5, according to Ohio State University. Mix in some farmyard manure, as well as a sprinkling of pellet slow-release fertilizer, or chicken manure.

3

Buy asparagus crowns from a plant nursery, or take some from a friend's garden, with permission. Crowns develop into edible plants much quicker than seeds, which can take up to three years to reach harvest.

4

Dig a hole in the soil up to 6 inches deep and 10 inches wide. If you have a long container, dig a trench down the middle. Add a small mound of compost to the center of the hole or along the middle of the trench. Place the asparagus crown onto the mound and spread out the roots.

5

Place the container in a bright outdoor location, ideally slightly raised from the ground on rocks or wooden feet. This will allow for more water drainage. Water the pot regularly. Soil should be kept moist, but do not allow it to get too wet.

6

Harvest asparagus by breaking off ripe, green spears that are over 7 inches long. Do not harvest in the first year. Allow the plant to grow, then take spears for cooking and eating in year two.
