The Trick is in the Trench Add fertilizer or an inch of compost, then an inch of soil. Lay the roots flat on either side of the crown and cover all with two inches of soil. Keep an eye on your new plants; as they grow, add more soil so the asparagus is always under two inches of soil.
How do you start an asparagus bed?
Soak the crowns briefly in lukewarm water before planting. Make a 2-inch-high ridge of soil along the center of the trench and place the asparagus crowns on top of the mound, spreading their roots out evenly. Within the trench, space asparagus crowns 12 to 18 inches apart (measured from root tip to root tip).
What does an asparagus bed need?
So keep your asparagus bed well-mulched from the start, using shredded leaves or straw. For the first couple years, weed often and carefully — asparagus roots are near the surface and can be damaged by weeding tools. Don’t interplant other vegetables in the same bed. Asparagus hates competition of any kind.
How do you make a raised bed for asparagus?
Most of today’s asparagus crowns need to be planted six-inches deep. To plant them in a raised bed, just fill the bed with six inches of soil (half way, if your bed is a foot deep). Then, lay the crowns a foot apart, and spread the roots out around them, like you see here.
How long does it take to establish an asparagus bed?
The seedlings themselves require several weeks to reach two inches in height, the size right for transplanting into a growing bed. It takes three to four years for a young plant to develop the maturity needed to support annual harvests that last four to six weeks.
Are coffee grounds good for asparagus?
Asparagus prefers a soil pH between 6.5 and 7, which is mildly acidic. Coffee grounds can run 5 or less on the pH scale by themselves. The grounds also add some nitrogen, which is a regular nutrition need of asparagus.
Can you grow asparagus in a raised bed?
By planting the asparagus crowns in a raised bed with a soil mix that includes loamy, organic matter, you can ensure good drainage. Another reason to plant asparagus in a raised bed is because it is a perennial crop and can remain productive for 10 to 12 years.
Where do you put an asparagus bed?
Asparagus plants have deep root systems. Avoid areas with shallow soils, or soils prone to water-saturation. If the asparagus bed is to be part of a larger vegetable garden, the best place is at the north end of the garden, so that the tall ferns do not shade the other crops.
How deep should asparagus crowns be?
Plant your crowns as soon as possible after delivery. Because asparagus enjoys really good drainage, it’s best planted in trenches of around 20cm (10″) deep by 30cm (12″) wide. Fill the bottom of each trench with 7cm (3″) of well-rotted manure or garden compost to help feed the plants in future years.
How deep should an asparagus bed be?
To plant asparagus crowns, dig trenches 12 inches wide and 6 inches deep (8 inches in sandy soil) down the center of the prepared bed. Soak the crowns in compost tea for 20 minutes before planting. Place the crowns in the trenches 1½ to 2 feet apart; top them with 2 to 3 inches of soil.
What can you not plant near 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?
If planted too close together, asparagus crowns will produce new stalks for only a few years. With enough space and good care, the crowns should last at least 20 years. Do stay ahead of the weeds; asparagus will give up instead of competing with them.
Should I soak my asparagus roots before planting?
Planting crowns will establish your asparagus bed faster so that you can harvest the asparagus sooner. Soak it in tepid water for two to three hours before you’re ready to plant. Asparagus planting instructions recommend that you plant the crowns 8 to 12 inches (20 to 30 cm.) apart.
What month do you plant asparagus?
Plant asparagus in spring or fall in a sunny spot with nutrient-rich, well-drained soil. 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.
How many asparagus plants should I plant?
But, if space is not an issue, 10-20 plants per person is a good start. Since asparagus is a perennial crop, site selection is going to be important. It’s not uncommon for asparagus plantings to last for 15+ years. It does best in well-drained soils that are in full sun.
What is the best natural fertilizer for asparagus?
Asparagus loves phosphorus. Composted manure, bone meal and rock phosphate are all good amendments to keep soil levels high in this nutrient.
When should I burn my asparagus?
As soon as the field is passable in early spring, mow or chop the old asparagus ferns with a brush hog mower or flail chopper if not chopped in the previous fall. Alternatively, they can be burned down with a controlled burn. Burning helps eliminate asparagus beetles that have overwintered in the old ferns.
