So far, nothing. I am looking at purchasing 3 yr old male crowns. Can they be harvested in the first season? When is the best time to move them? And would I have to make them go dormant before planting them???

Notify of. Can I still add soil, as I did when they were first planted? Thank you. The soil in raised beds will settle over the course of the season and as plants draw nutrients from the soil. Add 2 to 4 inches of commercial organic planting mix or loamy aged compost to your raised beds twice a year. Lightly mix the new soil in with the old soil. The only time you will need to completely replace all of the soil in a raised bed is if or when you find a soil-borne disease that affects your plants.
I planted 2-year crowns into a raised bed last year, let them flower, then I trimmed them down for the winter. They have shooted this spring and begun to flower. Should I repeat and NOT harvest or harvest this year? Asparagus crowns should grow to full strength in 3 to 4 years. Since your plants are in their third-year harvest a few spears this year but let the other grow on; their ferny stops will help roots store more energy for a full harvest next year.
Asparagus plants can produce for 15 years or more so you have many full harvests ahead. Asparagus crowns may take several weeks to establish themselves below ground.
If the crowns roots were healthy and plump not dry when you planted them then it will be a matter of time before the roots become established and then can push new growth to the surface.
Keep your soil evenly moist, not wet and never dry. If the weather is hot where you are, you may want to place a floating row over the planting bed to protect the soil and crown from solar heat. I wish to divide my mature crowns to enlarge my bed by another row or two. I note that you suggest doing this in early Spring, It will be difficult to do this before new sprouts emerge as they do this very soon after the frost leaves the ground, Can the crowns be dug up and divided while the new shoots are emerging or must I try to get this done in the short period before the sprouts emerge?
Asparagus crown division can be done as soon as the soil can be worked in spring. If the soil does not freeze where you live, you can divide crowns in winter. You can also divide crowns in autumn after the top growth dies back. If you divide in autumn, be sure to add several inches of aged compost or mulch over the planting bed to protect the crowns from freezing temperatures in winter.
I live in Arizona and my asparagus never seem to turn brown or die back. My plants are about 4 to 5 feet tall. How do I know when to cut them back so I can add more soil in my raised bed? You can cut them back to the ground in mid-fall or early winter just as though they were experiencing the change of season from warm season to cold season.
Once cut back you can more soil or mulch over the top of the bed. My asparagus bed is around 20 years old. I am in Oklahoma. Every summer small annoying trees invade my asparagus plants. Once the ferns are getting tall, the trees get out of control. They are larger than the asparagus ferns. Would it hurt the asparagus if I would try burning the ferns and trees in late winter when they were dormant? The crowns of your asparagus plants are not far below the surface.
Burning the asparagus ferns and trees would likely damage the asparagus crowns and could destroy in full or part your future harvests. The trees you spot in your asparagus bed are probably suckers growing from the roots of a nearby tree. Can you identify a nearby tree with similar leaves? If so, dig down 18 to 24 inches on the side of the raised bed where the tree is growing; you will likely find roots growing from the tree to the moisture in your raised bed.
Slice these roots and insert a root guard of sheet plastic or sheet metal down into the soil as a barrier. Then carefully remove the tree suckers in the asparagus bed. If there are no trees nearby then the trees may be growing from seeds dropped by birds.
Dig down and remove as much of the tree roots as you can. Thank you so much for responding and for the information. Unfortunately, it us a large asparagus patch and numerous trees that digging up the roots would be almost impossible. I appreciate you taking the time for your advise.
Next time you are at the garden center ask for a sucker stopper; this is a spray that contains a systemic herbicide. Spray each sucker with this herbicide; to keep the herbicide from reaching the asparagus patch use newspaper, cardboard or a bottomless paper bag to surround the sucker then you spray it; this will keep the herbicide mist from drifting onto other plants. How much cold will the roots take in the winter.
I am in the Yukon. I can cover with lots of straw but the bed will still experience freezing temperatures. Asparagus roots can withstand temperatures as low as F. Protect the planting bed with a very thick layer of straw or aged compost and then straw on top. This March 21, I will have have had my first year of asparagus in my raised bed of 8 x15ft. Here in Georgia, the weather is crazy and can go from 28 degrees to 80 degrees in 24 hours. I grew from seeds and they grew thick and bushy.
So when I saw the first freeze coming, I cut them all to ground level, backfilled with manure, leaves and straw to keep warm. A couple of weeks later, they were , some of them were over two feet tall again. I have not been sure how to deal with this, except to cover with more straw and blankets on freezing nights and then take off during the day. Should I cut back down to the ground again or just leave them growing?
ALot of what I cut back is still cut and looks dried up and dead. I sure hope they are not dead. I am a bit confused with this whole process as this is only the end of the first year, and some om my stalks are thick as my pinky already.
Any suggestions would be appreciated, thank you, Greg. During the first two or three years of asparagus growing, the important growth is below ground as the roots grow large and strong. As a perennial vegetable, you pretty much plant it and give it minimal care like other perennial plants.
Planted in early spring, asparagus grows rapidly right away and returns every year. They were delicious! Since then, the crowns have produced large crops year after year. Besides the food they provide, these are really beautiful plants. Some years mine grow over 6-feet tall, forming a lovely privacy barrier in the back of the garden. Asparagus crowns the root system of a young asparagus plant used to start new plants can be ordered by mail in late winter.
Garden nurseries will ship them when the time is right to plant them in your area. You need to have a full-sun garden bed all ready. I started my asparagus at the same time as cold-loving spring crops like peas. I ordered ten Jersey Giant crowns by mail and planted them at the end of April into a new raised bed. This is around the time of our last frost each spring. This lists organic seed and plant mail-order companies in the United States and Canada. Once the spears again grow through the layer of soil, add an additional 2-inch layer of soil.
Repeat this process until the trench has been filled to ground level. Depending on how deep you dug your trench, you may need to add soil 1 to 2 more times throughout the season. Learn how to plant and grow an asparagus bed in our video:. Caring for Asparagus When the trench is filled, we would recommend adding a 4- to 6-inch layer of mulch.
The biggest issue with asparagus is managing weeds during the first two years. Weeds will become less of an issue as the plants fill in. Mulch around the plant with compost or grass clippings to help retain soil moisture and reduce weed growth. During the first 2 years after planting, asparagus plants need 1 to 2 inches of water per square foot per week.
If you are not receiving adequate rainfall, you will likely need to water. Use drip irrigation if possible. Asparagus thrive on a steady supply of plant food. Consider an organic fertilizer during the growing season. Follow instructions on the label of whatever product you use. Before Harvesting Do not harvest the spears in the first or second year the plant needs time to grow out its root system , but cut down dead foliage in late fall and side-dress with compost.
During the second year, side-dress with compost in spring and early fall and cut down dead ferns in late fall. Keep the bed thickly mulched. During the third year, the bed should be in full production, so you can start to harvest asparagus sparingly throughout the season. Transplanting Asparagus If you must move asparagus, transplant the crowns in early spring when they are dormant or in late fall before the first fall frost after foliage is cut back.
Dig and lift crowns with a garden fork, being very careful not to disturb the roots. Divide the clump into two or more pieces. Water transplants. Do not harvest heavily in the following year. Find more cutworm prevention tips here. Destroy infected plant matter; choose resistant varieties; ensure good air circulation; avoid planting new asparagus nearby Asparagus is considered a deer-resistant plant , though a hungry deer will eat almost anything.
How to Harvest Asparagus Do not harvest during the first couple seasons see information above. If you have young plants, the season may last 2 to 3 weeks.
However, established plants produce longer—up to 8 weeks. Check your plant every other day for harvest-ready spears. Spears grow quickly and may become too woody before you know it! Bear in mind that younger, thinner spears will be more tender, so harvest according to your own taste. To harvest asparagus, simply cut the spears with a sharp knife or scissors at ground level.
Stop harvesting spears when the diameter of the spears decreases to the size of a pencil. After harvest, fertilize your asparagus in early summer. You can top-dress with a balanced organic fertilizer, or scatter another inch of rich, weed-free compost over the decomposing mulch. Do NOT cut down the remaining ferns in summer or you will ruin your asparagus bed. Always leave at least two or three spears on the plant through the growing season.
This is usually in early winter after several hard freezes. Cut the ferns back to the ground. Fertilize the bed with a 1-inch layer of rich, weed-free compost or manure topped with 3 inches of straw, rotted sawdust or another weed-free mulch.
Clean spears will push up through the mulch in spring. Brush off any visible dirt or give the spears a light washing with cold water before storing. To store, bundle the spears together, wrap the stem ends of the spears in a moist paper towel, and place the bundle in a plastic bag.
Store in the crisper drawer of your refrigerator. If you have enough space in your fridge, you can also store asparagus by placing the spears in a cup of water. Keep about an inch of clean water in the cup. A pinch of baking soda in the cooking water keeps beans , spinach , and asparagus greener.
