Garden asparagus
Plant Care Instructions By Steve Brigham

Asparagus are easy to grow in Southern California. Although it\'s best to wait until the plants\' third spring to start harvesting, your plants will continue to produce heavily each spring for 10-15 years after that. Good soil preparation before planting is essential, but little maintenance is necessary. If you grow an \"all male\" variety such as \'UC 157\', \'Jersey Giant\', or \'Jersey Knight\', you\'ll avoid unwanted volunteer seedlings which may differ in quality from the original plants.

    • Buy

        Buy big, healthy bare-root plants as available.

    • Plant

        Plant fresh roots 12" apart in rich, well-drained soil in full sun or a little shade (good drainage is a must -- in poorly-drained soils, plant in raised beds). Dig trenches 12" wide and 8-10" deep, and mix in a generous amount of composted manure or other soil amendment plus some 5-10-10 fertilizer in the bottom of the trench. Plant roots so that the tops are 6-8" below the top of the trench, and cover with 2" of soil. As new plants grow, gradually fill in trench, but do not cover the new growing tips.

    • Water

        Water regularly and deeply during dry periods.

    • Propagate

        Propagate by division of established root clumps.

    • Sow Seeds

    • Water

        Water regularly and deeply during dry periods.

    • Mulch

        Maintain a good mulch around plants to keep roots cool and conserve water use.

    • Harvest

        Harvest new spears when they are 5" tall. For "white asparagus", cover new shoots with soil as they grow to protect them from the sun.
