Asparagus, Jersey Giant

Short Description

Best for high yield, fine flavor and the largest succulent spears.

Full Description

Asparagus-lovers, and we are many, prize Jersey Giant’s delectable flavor, extra-large spears and high yields—up to twice the yield of standard varieties. Jersey Giant adapts widely and resists fusarium wilt, crown rot and rust. As asparagus is a perennial, you plant it just once, and you will enjoy tasty spears for years. Bare roots can be planted as soon as they arrive in spring. Rooted plants are great for fall and should be planted 4-6 weeks before first fall frost. In 2 years, you'll have a light crop and a regular crop thereafter. Growing instructions included. Full or partial sun.

How to Sow and Plant

Asparagus may be grown from seed sown early indoors and transplanted outside after frost, from seed sown directly in the garden, from transplanted seedlings in fall or from year-old bare roots in spring.

Sowing Seed Indoors:

  • Start asparagus seeds indoors 8-12 weeks before outdoor planting date in spring in peat pots, plastic pots or trays. At least 2 x 2 inch cells works best.
  • Sow seeds ½ inch deep in seed-starting formula.
  • Keep soil moist at 70-75 degrees F
  • Seedlings will emerge in 10-14 days
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow. Incandescent bulbs do not work because they get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • Seedlings should be 6-10 inches tall with 4-6 stems with several buds coming from the crown when they are ready to transplant outside.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens cell structure and reduces transplant shock and sun burn.
  • When selecting a site, keep in mind that asparagus is a perennial vegetable and the planting bed should not be disturbed. Early soil preparation is essential in order to establish a healthy asparagus bed. Asparagus prefers full sun and a good organic well drained soil.
  • Space transplants 12 inches apart in a single or double row. Double rows should be 12-14 inches apart. Transplant before temperatures are 90 degrees F.

Sowing Directly in the Garden:

  • Direct sow seeds in spring when the soil is at least 60 degrees F.
  • When selecting a site, keep in mind that asparagus is a perennial vegetable and the planting bed should not be disturbed. Early soil preparation is essential in order to establish a healthy asparagus bed. Asparagus prefers full sun and a good organic well drained soil.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth.
  • Sow seeds evenly and thinly 2 inches apart, ¾ -1 inch deep
  • Firm soil lightly with your hand, water and keep evenly moist.
  • Seedlings will emerge in 10-14 days at 75 degrees F, a little longer if the soil is cooler.
  • Thin seedlings to about 12 inches apart when seedlings have at least two sets of leaves.

Planting Bare Roots in the Garden:

  • When selecting a site, keep in mind that asparagus is a perennial vegetable and the planting bed should not be disturbed. Early soil preparation is essential in order to establish a healthy asparagus bed. Asparagus prefers full sun and a good organic well drained soil.
  • Dig trenches 6-8 inches deep and 12-15 inches wide. Space rows 2 ½ - 4 feet apart.
  • Set roots in the bottom of the trench, spacing crowns (centers) 18 inches apart in the row. Spread roots out as far as possible for best root establishment.
  • Cover roots with 2 inches of fine soil and water well.
  • Plants may take 6-8 weeks to emerge.
  • Continue adding soil as the tops grow up, about every three weeks, until the trench is full, which should be about midsummer when planted in early spring.

Planting Seedling Plants in the Garden:

  • When selecting a site, keep in mind that asparagus is a perennial vegetable and the planting bed should not be disturbed. Early soil preparation is essential in order to establish a healthy asparagus bed. Asparagus prefers full sun and a good organic well drained soil.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Set plants in the bottom, spacing centers 18 inches apart in the row. Space rows 2 ½ - 4 feet apart.
  • Place the top of the root ball approximately ½ inch below the level of the surrounding soil.
  • Fill with soil to the top of the root ball.
  • Press soil down firmly and water.

How to Grow

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Mulches also help retain soil moisture and maintain even soil temperatures. Put down a layer of newspaper 5-10 sheets thick between the rows (soak the papers in water first, so they won't blow away) and then cover the newspaper with dry grass clippings, aged bark mulch, weed-free straw, etc.  Always keep mulches off of plants’ stems to prevent possible rot.
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • Do NOT cut plants back after harvest, allow them to fern and grow as long as they can before frost. They will become quite large. They need the green foliage to make food for themselves to make strong plants next year.
  • Have your soil tested for fertilizer recommendations. Fertilize after harvest and in late summer.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • In late fall cut tops to ground level when they have turned brown. In cooler climates mulch the ground with evergreen branches or straw after the ground freezes for extra protection. Remove this winter mulch in early spring.

Harvest and Preserving Tips

  • Do NOT harvest asparagus the first year. Allow the plants to grow and make food to store in the roots for stronger plants the following year. When plants are two years old you can harvest them for a short period. In the third year you can harvest for four weeks.
  • Harvest when new spears emerge in spring. Harvest when spears are about ½ inch wide. On average spears should be 6-8 inches tall.
  • Using a sharp, clean knife, cut young spears at ground level and set in water with the cut side down until you are ready to store the spears. Some gardeners prefer to snap the stems, but this can cause damaged tissue which can result in disease issues.
  • Harvest frequently before spears start to leaf out.
  • Do not harvest spears less than ¼ inch in diameter.
  • Prepare as soon as possible as fresh asparagus is best.
  • Asparagus also freezes well for later use. Sort the spears by thickness and “blanch” smaller ones 1 ½ minutes, medium for 2 minutes and thickest for 3 minutes. To do this, drop the spears into boiling water for the recommended time, then plunge into cold water to stop the cooking, drain and store in freezer bags or vacuum bags.

Rated 5 out of 5 by from Good and healthy All 6 plants arrived nice and healthy and still doing great after transplanting to asparagus bed.

Rated 5 out of 5 by from Lots of Asparagus We started a second bed of asparagus this past spring because the first bed we plants was so tasty and sweet. We look forward to it every spring and wanted to be able to put asparagus up for the winter. Looking forward to a great harvest in the spring.

Rated 5 out of 5 by from These asparagus are fairly easy top grow. I followed the planting instructions and my asparagus started emerging within a week. The other nice thing is that you can harvest them the year after planting which is really nice because some asparagus require 2-3 years before you can harvest. I recommend these to anyone trying to grow asparagus!
