Before you plant

These conditions determine whether it will thrive.

Cold hardinessHardy here

Engelmann's prickly pear is hardy to about 10°F, so it never needs cover in Phoenix. The fruit ripens in summer, well after frost season.

Leaves and wood: damaged below 10°F
Heat toleranceTakes full sun and heat

Takes full and reflected west sun. Pads may yellow or wrinkle in long summer droughts, which a deep soak fixes.

Right plant, right place

Will Prickly pear grow at your Arizona property?

Use the whole site—not only the hardiness zone. Confirm mature width, reflected heat, seasonal shade, drainage, irrigation reach, and cold-air pockets before planting.

Planting & stewardship

How to help Prickly pear thrive

  1. 1

    Confirm the plant’s mature spread and underground conflicts before digging.

  2. 2

    Place the root flare at finished grade and keep mulch away from the trunk.

  3. 3

    Establish a wide, deep root zone instead of irrigating only at the trunk.

  4. 4

    Observe seasonal growth, heat stress, and wildlife use before making major pruning changes.
