Asparagus is a perennial plant with an erect growing pattern. The stems of the plant are edible and, in fact, are one of the more pricey vegetables on the market. Growing asparagus in the home garden is not difficult. Growing asparagus in containers, however, is quite challenging. Because of the very large root system you will need an extra-large container. To give yourself a head start, plant crowns, and not seeds. Growing asparagus from seeds will tack on an additional year until harvest. Even with crowns, you won’t be able to eat your asparagus until two years after planting.
Choose the container in which to grow your asparagus. To accommodate the horizontal growth pattern of the asparagus plant’s roots, called the crown, you will need a container that is at least 12 square feet, and a minimum of 5 feet deep.
Mix together equal parts of potting soil, compost, sharp sand and aged manure. Pour the mixture into the container.
Dig a 6-inch deep, 10-inch wide hole in the soil. Drop the crown into the hole and cover it with soil. If you are planting more than one crown, space them 12 inches apart.
Water the container well and allow the excess water to drain from the bottom of the container. Keep the soil moist at all times.
Things You Will Need
- Potting soil
- Aged manure
- Sharp sand
- Do not harvest the first spears that appear, as cutting them may damage the crown. Allow them to remain in the soil and mature into ferns over the winter. Cut them down to 2 inches in the fall.
