Mangifera indica

Matt's 9b field note

“'Has my wife's name in it... best tasting mango I've ever tried.' Planted May 2024.”

Background

An 'Edward' seedling from the breeding program of Gary Zill in Boynton Beach, Florida. It was named after the wife of Craig Campbell. Fairchild Tropical Botanic Garden notes the original tree was reportedly a light producer. Documented in Fairchild's mango cultivar materials. The UA arboretum traces mango cultivation to India, referenced in Hindu writings going back thousands of years; it is now grown in more than 87 countries.

Distinguishing traits

Large ovoid fruit that turns yellow when ripe; medium-firm, fiberless flesh with a rich-sweet, balanced classic flavor very similar to Edward, arguably sweeter. Moderately vigorous tree with dense canopy. Early to mid-season (May-July in Florida). The UA arboretum describes mango as a tall tree with new leaves flushing tan-brown before maturing dark green, and showy late-winter to early-spring flower panicles.

Desert care — zone 9b

Chill hours
Not a limiting factor; cool dry period triggers bloom.
Cold hardiness
Frost sensitive. Top Tropicals rates it for USDA zones 10-11, so Queen Creek 9b is marginal; protect young trees from any freeze. The UA arboretum flags mango as frost sensitive and notes it does not grow outdoors in the Sonoran Desert except in controlled environments.
Heat tolerance
Handles tropical heat with adequate water; young trees appreciate afternoon shade in extreme desert heat until established.
Water
Moderate watering; consistent moisture during fruit development, never waterlogged. The UA arboretum rates water use as high.
Soil
Well-draining soil with excellent drainage; slightly acidic to neutral pH. Avoid heavy clay and caliche zones.
Sun exposure
Full sun for optimal growth; protect young transplants from harsh afternoon desert sun.
