Oklahoma Gardening host Kim Toscano shows us how to properly fertilize it.

In this way, how often should I fertilize asparagus?

A. Asparagus can be fertilized in early spring before the spears emerge. An application of 1 to 1.5 pounds of an all-purpose garden fertilizer, such as 10-10-10, per 100 square feet should be adequate. Asparagus can also be fertilized after the last harvest in June.

Also, how often do you water asparagus? Watering Asparagus Plants

  1. During the first 2 years after planting, asparagus plants need 1 to 2 inches per week. If you are not receiving adequate rainfall you will need to water.
  2. Mulch around the plant with compost or grass clippings to help soil moisture and reduce weed growth.
  3. After year 4 you can reduce irrigation to every 2-3 weeks.

In this manner, what fertilizer is good for asparagus?

An application of 2 pounds of fertilizer per 100 square feet of bed provides sufficient nutrition for the young plants. Use a balanced fertilizer containing equal amounts of nitrogen, phosphorus and potassium, such as a 10-10-10 or 15-15-15 blend.

How do you maintain asparagus?

To keep the soil rich and help feed the asparagus plants, top dress the soil annually with compost or mulch. You can do this in early spring before the shoots appear, or in the fall after the fronds have died back and been cut to the ground.

Are coffee grounds good for asparagus?

* Coffee grounds alone would be too acidic, but if you're mixing them in with other kitchen waste and especially yard waste like leaves, they're fine. Asparagus prefers a soil pH between 6.5 and 7, which is mildly acidic. The grounds also add some nitrogen, which is a regular nutrition need of asparagus.

How do you rejuvenate asparagus?

Lay a two to three inch layer of mulch, such as straw, over your asparagus bed to help keep the weed population down, conserve moisture and keep the soil cooler during the hot days of summer. Adding a layer of compost under the straw wouldn't hurt. Do not apply salt as a way to kill weeds.

When should you stop cutting asparagus?

Stop harvesting when the spears are about the size of a pencil -- usually in 4 to 6 weeks. Allow the spears to open and take on their fern-like growth, which can reach 4 to 6 feet tall. Cut the plants back in late fall or winter, only after they've turned brown.

Should you put salt on asparagus plants?

Because asparagus is salt resistant, gardeners have used salt to kill weeds around asparagus plants. Asparagus will have to expend resources to prevent salt damage and can have a lower yield in salty soil. Asparagus is not immune to salt; enough salt in the soil will kill asparagus plants as well.

Why is my asparagus skinny?

Thin asparagus spears appear for a number of reasons, but the root cause is ultimately the same: the asparagus crown lacks the rigor to create bigger shoots. The ferns that grow from the crown aren't simply waste material to cut down, they need to be allowed to grow so your asparagus can recharge its batteries.

How do you keep weeds out of an asparagus bed?

Proper weeding prevents competition without damaging the asparagus root crowns.
  1. Spread a 2- to 3-inch layer of mulch, such as shredded bark, over the bed immediately after planting in spring to help suppress weed growth.
  2. Inspect the bed at least once a week throughout the growing season for weed seedlings.

How do you prepare the soil for asparagus?

Asparagus does best in lighter soils that warm up quickly in spring and drain well; standing water will quickly rot the roots. Prepare a planting bed for your asparagus, like this simple raised bed, that's about 4 feet wide by removing all perennial weeds and roots and digging in plenty of aged manure or compost.

Does asparagus grow back after you cut it?

After harvest, allow the ferns to grow; this replenishes the nutrients for next year's spear production. Always leave one or two spears. Cut back asparagus AFTER the foliage has died back and turned brown or yellow. This is usually in the fall after frost.

Does asparagus multiply?

The plants need a few years to grow and spread. You can harvest a few spears after one year, about half the year after that, and then all of the asparagus every spring after that. The plants multiply like rabbits (but not in an invasive way) and an asparagus bed can last for years, possibly even decades.

Why is asparagus so expensive?

Asparagus is expensive because the part you eat is the green* shoot of a woody plant. The green shoots are only on the plant for a brief time. Traditionally, it was a vegetable that was only available in early spring for that reason, but now it is imported from other parts of the world.
