How to Plant Asparagus
Asparagus is perennial . With right maintenance , a single plant can grow for ten years or more . Heirloom varieties also ego - seed which mean that it can ego - propagate in the same location even if the original plants eventually die of previous age .
With good care , you’re able to grow asparagus in the same location indefinitely . Once you get it spring up , it can also be impossible to remove without a whole lot of work . So choose your edible asparagus area cautiously .

Unless you have a job with fertile diggers like rabbits and voles , using irregular fencing or netting during the spear growing season ( springiness and sometimes devolve ) can be efficient to ensure good flora validation and eventually a salutary crop .

If you have challenge with garden diggers though , you ’ll also need to protect with fencing material that scat at least 2 feet cloak-and-dagger .
2. How Much Space?
Before you depart soil preparation , you need to picture out on the nose how much space to apportion to grow sufficient edible asparagus for your indigence .
Asparagus should be planted between 12 - 18 in apart with plenty of room for you to stand and harvest between your rows .
In dry orbit , you’re able to get aside with closer planting . However , in humid areas , wider spacing between plant helps to forbid fungal disorderliness .
3. How many plants do you need?
On average , ten salubrious asparagus flora will produce about 4 pounds of spears , set forth after the quaternary year of growing .
If you need 10 Ezra Pound of asparagus per year , you would take about 25 asparagus plants . With 12 inch spacing , this would take about 25 feet in agarden bed . With 16 in spacing , this would take a little over 33 feet .
That ’s a mass of elbow room for asmall garden . That sort of space will also take a slew ofsoil preparation .

Most traditional growers will prod six - inch oceanic abyss , industrial plant asparagus pate , and backfill the oceanic abyss with two inches of compost mixed with the original soil . If you have good soil , to begin with , this can work well .
My personal proficiency is a scrap dissimilar . I fag a trench that is about 1 foot deep and the breadth of my shovel ( nigh to 1 animal foot ) .
I mix my aboriginal soil with about one-half as much compost . Since we have heavy Lucius Clay , I commonly have to break up some clay clumps as I go .
Then I backfill with 6 inches of the soil mix . This give the edible asparagus turn a loss , compost plenteous soil to start arise in .
Asparagus needs a territory pH of 6.5 to 7.5 . If you do n’t know your soil pH , consider a territory test to regulate whether lime or sulfur product need to be applied to adjust your pH.

When the asparagus tips start poking through , backfill your trench with more grunge ( and more hay or stubble if you have it ) .
take over this process until you have backfilled all your soil to level .
Water deeply at time of planting and keep the soil moist until the soil is back up to grade .
7. Test-Drive Your Asparagus Growing Skills
If you want to try growing asparagus before you totally commit , grease one’s palms a bag of crowns and engraft them in craters near your already landscape areas that have similar pH planting requirement ( e.g. near deciduous flowering trees ) . I do this under my yield trees ( outside the subtlety pipeline ) .
get the picture a one - foot diameter hollow with a deep volcanic crater . Backfill the entire hole with compost instead of dirt . take up by filling it with 6 inch of compost , set your crown , and cover with two more inch . score it with a stake until the plant parts are visible .
As spears emerge , backfill with more compost until you are back up to grade . Cover with mulch and maintain as you would your other landscaped region ( for example veritable lacrimation , feeding , and weeding ) .

If you have no winter die back , then tailor out your older fern - like character as shortly as they show signs of aging ( for instance browning tips , fond dieback ) to make room for fresh emergence .
Weeding is essential for good plant establishment . Once your industrial plant have a lot of mass above primer coat , conceive bestow a few inch of mulch to cut down your work load and keep the territory moist .

There are two primary forms of Fusarium ( a fungous disorder ) , that can waste an asparagus patch . These are commonly called crownwork rot or root putrefaction .
These upset can reduce production , cause wilting , and browning of the industrial plant parts , and limit the plant ’s uptake of nutrients .
There is no literal discourse for these fungal infections . However , damaged asparagus plants are more susceptible to fungous infection . Humid conditions also make fungal contagion more likely .
