Will Asparagus grow at your Arizona property?

Light

Sun exposure

Full winter sun; give leafy crops afternoon protection during warm fall and spring weather.

Water

Irrigation

Keep the vegetable root zone evenly moist with regular irrigation; adjust to rain, soil, and temperature rather than using a fixed summer schedule.

Planting & stewardship

How to help Asparagus thrive

  1. 1

    Prepare a fertile, well-drained bed and keep seed or transplants evenly moist through establishment.

  2. 2

    Thin to the final spacing; crowding reduces harvest quality.

  3. 3

    Watch for aphids and caterpillars and protect sensitive growth from a hard freeze.

  4. 4

    Harvest before sustained spring heat causes bolting or poor quality.
