How Long Does it Take Asparagus to Sprout?

Asparagus was among the earliest cultivated vegetables with a history dating back to ancient Greek and Roman times. The vegetable is native to Asia Minor and is a member of the lily family. The major asparagus-producing areas in the United States include Michigan, California and Washington. For the most vigorous asparagus plants, it's best to start them from seed.
  1. Soil

    • Asparagus grows best in very sandy and well-drained soil as the vegetable is highly prone to crown rot. Do not plant in areas that remain soggy for over eight hours following heavy rainfall. Preferred soil pH is anywhere between 6.2 and 6.8. Add lime to improve pH in acidic soil six months prior to planting. Amend soil every year to maintain pH levels.

    Germination Time

    • Soak the seeds in water for four days before planting for improved germination. Plant the seeds directly in the garden for best results. Recommended seeding depth is 3/4 to 1 inch. The seeds start to sprout in 10 to 14 days at the optimal soil temperature of 75 degrees Fahrenheit. Once sprouted, growth is best during daytime temperatures of 85 degrees with nighttime temperatures of 65 degrees.

    Water

    • Water the plants regularly and thoroughly as asparagus is highly prone to drought stress. This is especially important during the first two to three seasons of growth. Neglect during a spring drought lowers plant yields for the following year. Poorly watered plants are also less able to handle the stress of diseases, pest infestations and weeds.

    Weeds

    • Asparagus does not compete well with weeds. Hand-pull weeds as needed. Do not use rototillers or other equipment that can easily damage the delicate crowns when removing weeds. Apply a 4- to 6-inch thick layer of an organic mulch to discourage weeds and help conserve soil moisture. Recommended materials include wood chips, grass clippings, hay or compost.
