Dig up the root in late fall after the last ferns have died back. Cut it into several pieces, each with plenty of healthy root attached. Replant them then or wait until spring after the last frost. Store the roots in a mesh or paper bag filled with sawdust if you chose the latter.
How do I get my asparagus to spread?
Asparagus needs space, so plant the crowns 12 to 18 inches apart. They won’t spread out much in the first couple of years, but once established, they will quickly fill in. Heirloom varieties need extra space, as there are both male and female plants, meaning they will produce seeds and will self-sow.

When should asparagus be divided?
To make more plants, you can divide well-established crowns in late winter or early spring. Do this no more than every three years, as asparagus plants can be slow to settle back in afterwards. Dig up the crown, handling it carefully.
Does asparagus spread once planted?
Yes, asparagus will spread as it grows. Asparagus roots can spread out up to 6 feet (1.8 meters) underground. Asparagus ferns (mature spears with foliage) can spread out 3 feet (90 centimeters) above ground. An older, more mature asparagus plant will send up more spears from its larger crown and energy reserves.
How can you tell a male asparagus from a female?
Asparagus Sex Determination
Asparagus is dioecious, which means there are both male and female plants. Female asparagus produces seeds that look like little red berries. Male plants produce thicker, larger spears than females. The flowers on male plants are also larger and longer than those on females.
How many spears of asparagus do you get from one plant?
20 spears
A mature stand of asparagus plants produces spears over several weeks, up to eight weeks. During this time, a healthy plant should yield around 20 spears.
How many years will asparagus come back?
15 to 30 years
Quick Guide to Growing Asparagus
Asparagus takes a few seasons to mature but will reap a harvest for 15 to 30 years, so choose a planting location that will go undisturbed for a long time.
Why do you have to wait 3 years to harvest asparagus?
In no year should you be considering asparagus harvesting for more than 8 weeks from the first cutting or you will weaken your crop for the following year. Whichever year you are in you need to cut your asparagus when it reaches about 4-6inches (10-15cm)in length.
Should asparagus be cut or snapped?
The thicker the spear, the more pronounced the difference when snapped. THE BOTTOM LINE: You’ll throw away more asparagus if you snap off the ends, and the spears won’t look as long and elegant. For many reasons, we think trimming and peeling is worth the effort.
Do you cut back asparagus in the fall?
At this point in the season, gardeners growing asparagus may be wondering when to cut down those tall, skinny stalks that have grown from their asparagus plants. Wait until the ferns are fully brown and dormant to maximize the next year’s harvest.
Do you cut off the bottom of asparagus?
It is not necessary to trim asparagus. On some spears, especially fresh, pencil-thin stalks, the woody ends may not tenderize once cooked. But on larger stalks, the ends of the asparagus are often woody and dense—Which makes them difficult to chew, no matter how soft the asparagus is after cooking.
How much of the asparagus bottom Do you cut off?
The woody part may be white, pale green, and/or purple, while the rest of the spear is bright green. However, that’s not always the case. As a result, it’s usually best to snap or slice off at least ½-inch from the bottom of all spears to cover your bases.
What should not be planted next to asparagus?
There are two main crops to avoid growing alongside asparagus:
- Alliums. Alliums like leeks, garlic, and onion sharing the soil with asparagus are said to stunt its growth.
- Potatoes. Asparagus, on the other hand, stunts the growth of potatoes when they share the same space.
What happens if you plant asparagus too close together?
Most asparagus planting instructions are for planting rows, but they indicate that spacing too-close can decrease yields and increase the risk of fungal disease.
Should you let asparagus flower?
Ferning out in asparagus is actually a good thing, as it indicates that photosynthesis is being promoted, therefore, nutrition production and absorption increases. During the ferning process, the majority of the energy produced is stored in the roots to facilitate new growth the next year.
Why should female asparagus be removed?
The female asparagus stalk will become fern-like and develop berries (but don’t eat them because they are toxic to humans). Over time these female plants should be removed.
How do you winterize asparagus?
How to Winterize Asparagus Plants
- Cut back the stalks and foliage to ground level in fall, after the leaves begin to yellow and die back naturally.
- Stop watering the asparagus after you cut back the stems.
- Spread 2 inches of mulch over the bed after you cut back the old stalks.
How tall should asparagus be before you pick it?
six to 10 inches tall
Spears should be harvested at six to 10 inches tall. Harvesting ends in late June or early July or when growth has slowed considerably. Fertilization, weed management and irrigation are important to maintain after harvest.
What month do you plant asparagus?
Plant transplants outside from November – February 15. Prepare the asparagus bed by adding compost and composted manure to create rich soil. If planting from seed, start seeds in small containers with potting soil or directly in the beds.
How much asparagus should I plant for a family of 4?
Growing white asparagus is a matter of layering soil over the spears so they don’t produce chlorophyll; you can do this with any variety. Ten crowns will fit in a 4-by-8-foot bed and are generally enough to supply a family of four.
