Commercial Asparagus Production Date: October 15, Asparagus is a high-value, early season perennial vegetable crop. Locally produced asparagus is available in the northern United States from late April — June.

After mowing, this also can be time for fertilizer and herbicide application. Fertilization rates should be based on needs outlined in periodic soil tests.

Growers have two application options. Some growers perform one application in early spring after mowing ferns. A second option is splitting the application between early spring and directly after last harvest. For weed control, we suggest applying pre-emergent material prior to spear emergence and burn off any post emergent weeds directly before harvest. Many growers have found no-till as a cultural practice, for weed control very beneficial as it can eliminate potential damage to the crown through cultivation.

Research shows you can harvest asparagus the year after establishment for 7—14 days and for 3—4 weeks on year 2 depending on spear diameter. In the third year, you can harvest for the full season, typically 6—8 weeks. Information used to write portions of this article can be found in Asparagus Production - From A to Z.

Female plants produce berries; males plants do not expend energy on berries so they can be up to three times more productive than female plants. For this reason, growing male asparagus plants is often preferred. White asparagus is not a variety, but simply asparagus grown in the absence of sunlight to prevent chlorophyll from developing. White asparagus is slightly sweeter, but has less fiber than green asparagus.

Purple asparagus is bred to be purple in color, but turns green when it is cooked. Purple varieties tend to have thicker spears, but fewer of them. Watch our video on how to properly clean and trim asparagus. A simple and easy favorite when it comes to asparagus is fresh roasted asparagus. Or try this simple, delicious asparagus soup. I have a small garden patch of asparagus started from seed coming up to two years from planting Spring I am in Ontario, Canada.

Well yesterday we had our first snowfall of the season Nov. Would it be good to cut it down now in preparation of the 3rd year of growth in the spring, or wait just a bit longer to see if the current stems and frawns turn color?

Hi Wayne, You have some strong plants! You are correct to wait- it is best to cut back the asparagus plants once all of the foliage and stalks have turned yellow or brown. This will give you a better harvest next year. Be patient! We hope this helps. Although they are 2nd year crowns, they will still need time to settle in and grow out their roots after planting.

We would still recommend waiting years before harvesting any significant number of shoots, just so that your plants have a good chance to get established first! So, we want to start an asparagus bed and all the things we've been finding say you have to plant in early spring or fall. Can we get a bed ready and plant in June to just get the root systems started, or will that just be a waste of seeds?

We live in zone 6b St. Louis, MO. If you know of any resources to address this question, I would be so appreciative. I'm on year 2 of growing my asparagus and I have shoots coming up. I'm not going to harvest but do I just let them grow and die off, then trim back in the Fall? Just want to be sure:. Yes, precisely! Their job is to absorb as much energy as possible during the warm part of the year.

The snow melted and some of my crowns have been exposed including the roots. There are roots deeper down in the dirt I suppose but the top little cluster is exposed. If I place more soil on it, do you think it will continue to grow? I looked closely and there are tiny finger like parts close to the center but surrounding the center of the crown that looks pretty fresh. Thank you. Asparagus roots can reach as deep as six feet, so the plants have a strong foothold.

A few inches of compost should be fine. I planted an asparagus bed about 30 years ago. It is still producing spears but not enough. I want to plant 2 year old crowns this year.

Would it be OK to plant them in the same location as the original plants? One source suggests that an old asparagus bed should not be replanted for three years. Before you try something else you might try to rejuvenate your existing plants. Asparagus is a heavy feeder; it likes and needs rich compost and aged manure, as well as proper pH 6,0 to 8.

I am so pleased I planted a new raised asparagus bed with about 15 crowns about 7 years ago north of Denver, CO so I could resemble the bed my grandparents had in upstate NY. As a result, I have plenty of composted manure on hand for winter top dressing after the dead stalks and ferns are cut back and before the new shoots appear.

I always look forward to those first harbingers of spring and indulge in fresh asparagus for dinner. I have been able to successfully freeze asparagus to use year round in a variety of egg recipes. Quiche makes a terrific meal and is a great way to use up eggs and clean out the freezer to be ready for the new harvest. My chickens adore hiding between the stalks in the summer and help cultivate between the plants when the new top layer is added. The added benefit is they scratch up the ground thereby eliminating weeds, cutworms, and leave their droppings which only aids in fertilizing the ground and has contributed to the bed becoming crowded it is 5' by 15'.

My question is, should asparagus be divided or should I harvest more? To your question, no; do not try to divide it. Roots could be 6 feet or morel long. The plants might be closer in your bed, but if they are producing, enjoy it. I live in Henderson Nevada. At the end of December I trimmed the brown ferns leaving the stocks approximately two inches above ground and covered them with mulch.

To my amazement I have spears that are now growing well beyond the mulch they were covered with. One spear shot up to approximately inches the others are inches tall. Is this normal for the spears to continue to grow and can you eat them? I thought cutting them back and mulching for winter causes them to go into dormancy. Your advise is appreciated. Suburban gardener, I planted 11 feet of Mary Washington, and same of Purple Passion boring color when cooked about 17 years ago.

It makes me VERY happy!!! Just me to feed, so occasionally my neighbors get some. I was just wondering how long I must wait until I fold down the ferns, but you've given me the answer: I can CUT is short I don;t know why my habit has been simply to fold it down and use it for mulch after I put down the compost I have planned for it.

Thank you for THAT tidbit! Problem with straw is that it never rots Many thanks. Your outline and suggestions above are better presented and clearer. I am so sorry for the multiple submissions. I didn't think my question was being "saved. I'm wondering if these ferny growths currently around inches high are new future asparagus plants and if I should allow them to continue growing. As the young shoots continue to grow during the first summer, gradually fill in the hole with soil.

The tops of the crowns should be about 6 inches below the soil surface when the trenches are completely filled. This allows for cultivation by hoe or rototiller and also provides a sufficient depth of soil for new buds to develop on top of the crown. An alternative to using one-year-old crowns is to start asparagus transplants from seeds as you would start other vegetable transplants. About 6 to 8 weeks before planting, sow the seeds directly into pots.

Thin to one plant per pot and, after all danger of frost has passed, plant the young seedlings as described above for crowns. Do not cover the young shoots ferns with soil. Weeds are the most common problem in asparagus plantings, because they compete with the crop and reduce productivity. Do not plant asparagus or any vegetable in an area heavily infested with quackgrass or other weeds that spread by rhizomes.

If necessary, begin a year in advance to clean out the quackgrass, either by hand or mechanical cultivation or by spraying with an approved herbicide when the grass is 6 to 8 inches tall. If using herbicides, follow label directions precisely for safety and good weed control.

In addition to planting in an area free of weeds, it can be helpful to maintain a tilled border around the asparagus planting, to prevent weeds from outside the patch from migrating into the planting. To manage annual weeds, mulch with straw, grass clippings, chopped leaves, or pine needles after the trenches have been filled in.

Hand-hoeing while weeds are small is also effective. The asparagus beetle is the most serious insect pest that affects asparagus. The larvae are dark and slug-like and are found on the ferns. There are two types of asparagus beetle; the common asparagus beetle Crioceris asparigi and the spotted asparagus beetle C.

The adult spotted asparagus beetle is red with black spots, and the adult common asparagus beetle is metallic-colored with yellow spots. At the end of fall, remove all of the dead ferns and crop debris that would otherwise shelter the adult beetles.

If these practices do not control the pest, several insecticides are labeled for management of asparagus beetle. Asparagus rust and Fusarium crown and root rot are common diseases. Both diseases can weaken asparagus plants, so that the planting becomes less productive over time. Most varieties are fairly resistant to rust.

Removing old ferns provides additional protection. Fusarium is more difficult to control. Use vigorous varieties listed as tolerant and do not plant new asparagus in areas that were previously planted to asparagus. Do not harvest asparagus until the third year after planting. The plants need at least two full seasons of growth before they build up ample food reserves to sustain harvests.

In the third year, harvest only 2 to 3 weeks. In years thereafter, harvest no longer than 6 to 8 weeks until about July 1 in southern New Hampshire.
