Ask anyone who has grown asparagus how it compares to the store bought variety and they will be happy to go on and on about the amazing difference in flavor. They'll shake their heads and tell you that if you've never tasted freshly harvested asparagus, then you haven't tasted asparagus. Which shouldn't surprise you. After all, this is the case for many (most) vegetables.

Asparagus (Asparagus officinalis) loses its flavor rapidly once it's been harvested, which is exactly why you need your own asparagus patch.  Feel free to ignore the rumors about asparagus being a fussy thing with particular tastes. I don't subscribe to that asparagus description. In fact, I don't find them any more demanding than any other vegetable.

It's more likely that the nay-sayers are referring to the amount of time that asparagus needs to fully mature. And that's a shame. I mean the time is going to pass anyway. Am I right?

Think of asparagus as a "long-term perennial." Yes, you're going to have to wait about three years to savor a decent harvest. But asparagus consoles you by producing the most lovely feathery foliage. Plus an asparagus patch will keep producing for fifteen to twenty years -- can your tomato plants say that?

 

Planting and Growing Asparagus

For mild winter climates, asparagus is planted in the fall or early winter. If you're in a cold winter area, wait until early spring to get them into the garden bed. Asparagus can be planted as one-year-old (sometimes two-year-old) crowns or from seed. Both are acceptable, however, crowns are the preferred way since the gardener will gain an entire year or more of time as far as harvest goes.

The soil should be on the sandy side, well-draining, and rich. This means you'll want to add plenty of organic matter and compost. Asparagus prefers the soil pH to be slightly on the high side (6.5-7.5), but a little lower isn't a deal breaker. You can always toss in a little lime to bring up the pH.

 

Planting Asparagus from Crowns

Dig a 12" - 18" trench and make a mound all the way down the center of the trench. Plant the crowns 12"-18" apart (they like their elbow room) by spreading their roots around the mound at the bottom of the trench.  Cover the crowns up with several inches of compost or composted manure along with some of the soil that you dug out.  Water them well.


Once the plants start growing, you'll add more of the compost/soil mix. Continue this until the trench is filled. The idea is not to cover the tips of the growing asparagus. Asparagus likes water so don't let the roots dry out.

 

Plant Asparagus from Seed

Asparagus plants can be started from seed by planting them indoors about eight weeks before the last frost date in your area or directly into the garden outdoors three weeks before the last frost date. If you plant the seed directly into the garden bed, be sure that soil temperatures are at 77 degrees or higher. Plant the seeds ¼"-1/2" deep into the soil and they'll germinate in 10-12 days.

Asparagus prefers full sun (but will tolerate a range from 4-8 hours) and rich, free-draining, organic soil. Don't get stingy with the water -- they are thirsty plants and you can't give them too much organic matter while the spears are actively growing. 

Keep the bed free of weeds as they tend to rob the asparagus of the nutrients you've added to the soil. Mulching the bed with straw or damp newspaper will help smother weeds seeds and regulate soil temperature.

 

How to Harvest Asparagus Spears

The general rule-of-thumb is that you start harvesting the spears the second spring after the crown are planted; the third spring is even better. And certainly not until the third spring if you've started with seeds.

That said, the first harvest should be a rather light one -- don't try to feed the neighborhood with it. Harvest the spears by cutting them off with a sharp knife just below the soil line. Alternately, you can bend each spear until it snaps off just above the soil line.

Harvest two to three spears per plant over a two week period. Look for stalks that are about pencil thick to take from the plant and let the really skinny ones grow into ferns in order to be ready for the following harvest.

Every spring thereafter, harvest the spears that measure about 3/8" in diameter and 6"-8" tall. The harvests following that first one (the second spring) usually last for four to eight weeks. Stop harvesting when most of the spears that are left are small and have their tips open.
