This is grown by using mounds of soil or mulch to deprive the spears of light.
Are You following correct planting methods for asparagus?

When to fertilize asparagus?
After the asparagus patch is established, fertilizer, compost, or composted manure can be added either in early spring before spear emergence, or after harvest in late June or early July.

Site Selection
Soil Preparation
- Before planting, make sure that the soil is free of trash, soil insects, and perennial weeds such as johnsongrass or bermudagrass. Avoid sites where yellow nutsedge grows, as this indicates poor drainage, which is unsuitable for asparagus production. In late fall, spread a 3-inch layer of organic matter such as manure, rotted sawdust, or compost over the beds. Till or spade them to …
Varieties
- The hybrid asparagus cultivars ‘Martha Washington’, ‘UC 157’, ‘Jersey Giant’, and ‘Mary Washington’ produce better than the standard cultivars. Male asparagus cultivars such as Jersey types (‘Jersey Giant’, ‘Jersey Knight’, and ‘Jersey Supreme’) are more productive and resist disease better than the female cultivars (‘Washington’ types). Also, female cultivars are less vigorous an…
Planting
- Asparagus is grown from 1- or 2-yearold crowns planted in January or February, or as soon as the ground can be worked. Crowns can also be grown from seeds planted in flats or peat cups. It takes at least a year to grow a good crown. To shorten the period from planting to harvest, buy and plant healthy, vigorous, 1- or 2-year-old crowns from a nurse...
Fertilizing
- Before planting a new asparagus bed, broadcast and spade in or incorporate ¼ pound of nitrogen, phosphate, and potassium per 20 feet of row or as directed by a soil test report. For established beds, scatter 2 pounds of 10-20-10 fertilizer (or its equivalent) per 20 feet of row before growth begins in the spring, late January, or early February in most areas of Texas. After the last harvest…
Watering
- Asparagus plants need frequent, deep watering. Water the beds thoroughly, and allow the top 1 inch of soil to dry before watering again. The time varies from 3 to 5 days, depending on soil type and temperature. In sandy soils, asparagus roots can reach 10 feet deep if adequate soil moisture is available.
Care During The Season
- Asparagus competes poorly with weeds. For asparagus to grow vigorously, weeds must be controlled in the first 1 to 2 years of its establishment. To suppress weeds, spread a 4- to 6-inch-thick layer of organic mulch, such as hay, stray, compost, wood chips, or grass clippings. Asparagus beds require little care after the first 2 years of establishment. Keep weeds pulled or …
Harvesting
- Harvest asparagus spears from established beds for about 8 weeks, depending on the area. Do not harvest during the first 2 years after planting. This waiting period enables the underground crown to grow and store enough reserves for a strong harvest for many years to come. Harvest the spears when they are 4 to 10 inches long. To prevent the spears from becoming fibrous, har…
Insects
- The most significant pest of asparagus is the asparagus beetle. Left unchecked, this beetle can greatly damage asparagus in a short period. The beetle overwinters (spends the winter) in crop residue or trash in the garden or in the border. If you see beetles feeding on asparagus, remove them by hand or spray them with Surround (organic insecticide) or Sevin.
Diseases
- If you select a good site with proper drainage and pH, you can reduce if not prevent the establishment of many asparagus diseases. Common diseases that attack asparagus are crown rot and rusts; they can be controlled with organic chemicals such as sulfur or potassium phosphite.
