Cultivation
- Its possible to grow asparagus by seed, but most farmers and gardeners leave this part to a professional nursery because the seed is so finicky to germinate. Instead, buying asparagus crowns a technical term for the dormant roots is recommended. They look like a strange sea creature with roots for tentacles and a head in the middle where the spears sprout. Asparagus li…
Availability
- The dormant crowns are available at local garden centers for a brief window in early spring, after the ground thaws, but before the crowns start sprouting. If you miss that window, its still possible to order them online from nurseries farther north. Some growers keep asparagus crowns in their walk-in cooler to prolong dormancy so southern gardeners running late on the garden season h…
Varieties
- Heirloom varieties like Martha Washington are still quite popular, though they produce male and female plants. Female asparagus plants produce pretty red berries in fall, but they make far fewer spears. To get a larger harvest, many growers opt for all-male hybrid varieties like Jersey Giant or UC 157, which are highly productive and usually more disease-resistant than the heirloom types…
Preparation
- Ten crowns will fit in a 4-by-8-foot bed and are generally enough to supply a family of four. Try to time your purchase so the asparagus crowns can go in the ground without delay. If you have to store the crowns for more than a day or two, place them in a bucket of moist sand in a basement or other cool environment until you are ready to plant.

- *Your local cooperative extension service office can test your soil pH and tell you exactly how much lime to add to bring it up to 7.
Design
- Unharvested spears will unfurl into a lacy canopy of foliage about 3 or 4 feet tall by early summer. Allowing the stalks to grow each year is necessary for maintaining a strong root system making it possible for the asparagus to come back year after year with bigger and bigger spears.
