How Far Apart Do You Plant Asparagus

Plant seed in spring, about one inch deep, spaced two to three inches apart, within rows that are a foot apart. Seeds can take three weeks to germinate. Keep the nursery bed free from weeds, as the asparagus seedlings will not be able to compete with strong weed growth.

How much space do asparagus plants need?

Rows of asparagus should be at least 2 feet apart, allowing two rows to fit in a 4-foot wide bed. For every 8 feet of row space, you will need about a wheelbarrow filled two-thirds of the way with equal parts of the excavated soil and compost.

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.

Can you plant asparagus 12 inches apart?

Dig the planting area at least 6- to 12-inches deep and about 12-inches wide. Space individual asparagus plants 12- to 18-inches apart for room to grow. After digging, but before planting, combine any soil additives needed (like compost, aged manure, fertilizer, etc.) with some of the top soil.

What month is best to 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 close can I plant asparagus in a raised bed?

In a raised bed, you don’t have to space the “rows” so far apart! Because you can walk around your bed easily, there is no need for large rows to access your plants. You can simply space the asparagus crowns 18 inches apart from every other plant.

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 is the closest you can plant asparagus?

One is the close spacing. Conventional planting instructions, like those given by the University of New Hampshire’s extension service, suggest planting asparagus 18 inches apart in rows 5 feet apart. Biointensive gardeners tighten this spacing considerably.

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 plant asparagus in a square foot garden?

How Many Asparagus Can Be Planted Per Square Foot? Traditional row spacing for asparagus crowns is 9 to 12 inches apart in a 12- to 18-inch-wide trench. In a square foot garden, each 12-inch square can hold two asparagus crowns.

Where should I plant asparagus in my garden?

The best planting spot is sunny but sheltered (picture a garden patch protected by mature trees). Plants crowns so they leaves are clear of the soil. You can plant as soon as you can work the soil, but stay vigilant with the blankets in case of freak spring cold snaps. Make sure the soil drains well.

Does asparagus multiply?

When asparagus plants are growing in a sunny site with good drainage, proper irrigation, and adequate nutrients, the plants multiply and become crowded over time. The ability of asparagus plants to multiply means that sharing the bounty is part of the fun of growing this perennial vegetable.

Should I let my asparagus go to seed?

Comments for Asparagus Plants Have Gone to Seed Don’t cut them back until autumn if you miss the cutting season, just let them grow.

How do you increase yield on asparagus?

A key factor contributing to yield in asparagus is the amount of carbohydrates stored in the crown (root system) at the time the crop goes dormant – sometimes referred to as the “energy of the crown.” During the harvest period, these carbohydrates stored in the crown are depleted to sustain continuous spear production.

How deep should asparagus bed be?

Asparagus crowns are usually available just once a year in early spring. So plan accordingly. Once the bed is weed-free, dig a trench about 12″ deep and a foot wide. The crowns should be planted at 18″ intervals in the bed, so put a shovel of compost and a cup of all-purpose, organic fertilizer in the trench every 18″.

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.
