Product Description

This all-male variety yields the best-quality spears of the Jersey hybrids. Each mature plant will produce 7-9 quality spears with slightly purple bracts. Spear diameter is between 1-2cm (3/8-3/4″). Jersey Knight has a high tolerance to fusarium wilt and crown rot as well as rust and cercospera. Planting asparagus from seeds is extremely economical, but it’s also very slow. We recommend starting seeds indoors and transplanting out into well prepared permanent beds in late spring. To develop strong plants, no asparagus is harvested for the first two years of growth. Rather, the plants are left to develop their tall, ferny foliage. This will allow them to establish thick, functioning roots for nutrient intake. In the third year, 40% of the spears can be harvested.

Ready to harvest in the third growing year. (Hybrid seeds)

How to Grow Asparagus

Planting asparagus seeds is an exercise in patience, but one of the most rewarding of all garden tasks. Asparagus Seeds germinate slowly, and the crowns take three seasons before they can handle being harvested. However the grower’s patience is generously rewarded by early season harvests of asparagus with a flavour you will not find on store shelves anywhere. You will wish you had planted a bigger asparagus bed!

Latin
Asparagus officinalis.
Family: Liliaceae

Difficulty
Moderately difficult. Requires patience!

We Recommend: Jersey Knight (AS107). It takes time to grow asparagus from seeds, but Jersey Knight is lovely! If you are in a hurry try Guelph Millennium Crowns this season.
For Urban Gardeners: Guelph Millennium Crowns (AS108). Planting crowns is simply the faster route to harvesting home grown asparagus. Try growing some in a half barrel or similar, quite large container.

Season & Zone
Season: Cool season.
Exposure: Full-sun.
Zone: Hardy from Zone 2 to 8.

Timing
Start seeds indoors mid-February to May under bright lights. You won’t start harvesting these long-lived perennials until 3 years after planting so be patient. Soil temperature for germination: 21–30ºC (70–85ºF).

Starting
Soak seeds for 2 hours. Plant 1 seed per 5cm (2″) pot, 1cm (½”) deep. Keep in a warm place. Be patient: they can take 2-8 weeks to sprout depending on soil temperature. Transplant when seedlings are 10-12 weeks old and danger of frost has passed. Space 45cm (18″) apart in rows 1-2m (3-6′) apart. Place each plant in a hole 10cm (4:) deep and gradually cover the crown with soil as it grows. For thicker spears, space 30-35cm (12-14″) apart and set buds 15-20cm (6-8″) in the hole. For thinner spears, space 20-25cm (8-10″) with the budes 10cm (4″) deep.

Growing
Fertilize after harvest and again in the spring with 1-2 cups of complete organic fertilizer per 3m (10′) of row, worked in lightly. Asparagus needs 2cm (1″) of water per week. In late fall, trim ferns down to 5cm (2″) and dispose of cuttings to avoid future disease and insect problems.

Harvest
It’s important to not harvest until the third year so that plants can become established and strong. Then harvest over a 2-3 week period. Cut the fattest spears off at ground level when they are 15-20cm (6-10″) long. When thinner spears begin to emerge let them to grow into big fronds to nourish the roots. With each successive year the harvest lengthens to a maximum of 6-8 weeks. Store in the refrigerator wrapped in a damp paper towel.

Seed Info
In optimum conditions at least 75% of seeds should germinate. Usual seed life: 2 years.

Diseases & Pests
Rust, fusarium wilt and fusarium stem and crown rot. Using seed started in sterile soil instead of purchased plants, and planting in soil that has no history of disease will keep your plants healthy.

Asparagus beetles can defoliate the ferns of the asparagus plant. They overwinter in the top growth, so thorough removal of the fronds in the fall (after they have died) is vital. In a small garden handpick the voracious insects.

Encouraging beneficials like ladybugs reduces aphids. Aphids are usually found together on growing tips (look for the sooty blotches they leave behind).

Companion Planting
Plant asparagus seeds or crowns with asters, basil, cilantro, dill, cilantro, marigolds, nasturtiums, oregano, parsley, peppers, sage, and thyme. Asparagus repels nematodes that attack tomatoes, and tomatoes repel asparagus beetles.

    :

    I started asparagus seeds in dec and they are growing quit well. I planted the first seeds and thought they died so I soaked five remaining seeds for two hours in water and SubCulture. The five I planted last sprouted very quickly and the ones I thought had died are now growing as well. I find with asparagus that time does fly as I have 4 four year old & 6 two year old plants started from roots. this will be my first plants from seed.
