1. Not Planting Deeply Sufficient
Asparagus crowns choose to be buried a number of inches into the earth. They need to be planted in rows about eight inches deep, so the shoots are going through up.
Cowl crowns with three to 5 inches of soil, including extra because the shoots emerge till the ditch is stuffed in.
For those who discover the crowns should not fairly deep sufficient, don’t fret, simply add a few inches of soil till they’re appropriately lined.

2. Lack of Water
These vegetation are reasonably drought tolerant and can survive with out a variety of water, however dry circumstances will trigger them to develop extra slowly and produce thinner, weaker stalks.
In the course of the first couple of rising seasons, vegetation ought to obtain one to 2 inches of water per week. Older vegetation want about one inch per week.
Water a few times every week, or each time the highest inch of soil feels dry.
For the reason that crowns could also be buried a number of inches beneath the soil, it is very important water deeply sufficient for the moisture to achieve the roots.
3. Nutrient Deficiency
These heavy feeders must be planted in nutrient-rich soil amended closely with compost.
Personally, I’m not a fan of artificial fertilizers and don’t use them in my backyard. I’ve discovered that aspect dressing the backyard mattress with about an inch of compost every season appears to do the trick.
As soon as the spears start to emerge, I additionally like to use a thick mulch to construct vitamins over time whereas additionally serving to to retain moisture within the soil.
I personally use grass clippings, that are excessive in nitrogen and break down rapidly. However straw, hay, bark, or shredded leaves will all work too.
For those who select to fertilize, achieve this in fall or early spring earlier than shoots emerge, utilizing an all-purpose natural fertilizer.
It’s helpful so as to add amendments excessive in phosphorus comparable to bone meal, aged manure, or rock phosphate to help wholesome root progress. These could be added into the ditch when planting, or sprinkled across the mattress every spring.

4. Overharvesting
Even when your vegetation are producing the thickest potential spears, after about eight weeks, they may naturally cut back in thickness to in regards to the measurement of a pencil and begin to fern out.
It is a signal that it’s time to cease harvesting.
And whereas it could be tempting to chop again the lengthy, fern-like foliage that grows after harvest season ends, resist the urge to take action till the autumn, when the leaves yellow and start to die again.
The foliage is vital for photosynthesis, offering the crowns the vitamins they should keep sturdy for the next season.
5. Age
Do not forget that it takes a number of years for asparagus vegetation to be prepared for harvest. These perennials want a number of years to develop sturdy roots earlier than they’re prepared to supply a full, thick crop.
Spears can be very skinny throughout the first couple of seasons of progress. Harvesting is just not suggested for not less than two years after planting, and must be carried out sparingly if in any respect within the third yr.
