Asparagus planting requirements

Soil

Asparagus is a perennial crop and will grow in the same spot for at least 15 years. Before planting, choose a location that you will not disturb or need in the coming years.

Asparagus grows best in alkaline soil, which is not an issue in most central Texas regions. Prepare the soil by adding good compost or well-rotted manure. Make sure there is no weed competition around it, such as Bermuda grass. You can grow your asparagus in raised beds if the location drains poorly, as it does not stand wet feet.

Sunlight

Asparagus grows best in full sunlight, but it can take part shade.

Planting

Asparagus crowns are a bundle of roots that connect in the center, somewhat similar to a spider. At planting, slightly mound the soil, then lay the crown draping the roots on the sides. The top of the crown should be 5-6 inches below the soil.

Watering

Asparagus does not like dry soil. You should water as soon as you notice the first top inch of soil is dry. Watering frequency will vary depending on soil quality and the season.

Fertilizing

Add an initial application of organic fertilizer at planting time. Then you can apply another dose mid-winter once established. After the last harvest, fertilize with a high nitrogen fertilizer to promote fern growth, which will feed the roots.

Harvest

The crowns are two to three years old at purchase time, so in the first growing season, the spears come out very thin and should be left to grow into ferns. They grow up to four feet tall during the summer, then die back with the first hard frost.

Allowing the ferns to grow feeds the crowns encouraging better spear quality the following year. After two years of growth, the spears have a better thickness and are ready for harvest. Avoid harvesting any spears that are less than a pencil-size thick. Always leave a few spears to grow into the foliage to strengthen the roots.

How to care for asparagus?

Asparagus does not appreciate weed competition, especially during the first two years of growth. Make sure to remove any undesirable growth as soon as it appears. To help suppress the weeds, spread two to three inches of mulch.

At the first hard frost, cut back the yellow foliage to the ground and add some compost to the bed. Sometimes a few spears appear in the winter if it is not cold enough, and they are edible.

Pests

Asparagus beetle is the main pest that could destroy your asparagus. The insect overwinters in the plant debris, which you must discard immediately after cutting it back. If you encounter a beetle feeding on your asparagus, just hand puck it or use an organic insecticide in case of an infestation.

    1. After planting, you should give it two years before starting to harvest anything. The spears will turn into ferns during the summer. The foliage will feed the roots for the following season. In the third year, you can start harvesting spears that are one in thick and five to six inches long.
