Meiwa Kumquat ★

Fortunella crassifolia

Matt's 9b field note

“Sweet enough to eat off the tree, peel and all. The kids strip it bare every season.”

Background

'Meiwa' (also called ninpo or neiha kinkan in Japan) is a round-fruited kumquat of uncertain origin, long grown in Zhejiang province, China, and Fukuoka, Japan; some authorities consider it a possible hybrid between Fortunella species. Introduced to the US via early-20th-century Asian citrus collections. It is the standard 'sweet kumquat' in the American nursery trade and is widely regarded as the best fresh-eating kumquat.

Distinguishing traits

Compact, nearly spherical evergreen tree, 6-15 ft (often kept 6-10 ft), thornless-ish, glossy dark green leaves. Fruit small, round to slightly oblong, bright to deep orange, 10-16 g, with a sweet, thick, spicy rind and mildly sweet-tart pulp; eaten whole, peel and all. Fragrant white flowers, cyclical blooming, fruit ripens November-May.

Desert care — zone 9b

Chill hours
Very low; kumquats are among the least chill-dependent citrus.
Cold hardiness
One of the hardiest citrus; established trees tolerate ~18-20°F (zone 8a).
Heat tolerance
Takes full desert heat well once established; young trees appreciate afternoon shade the first summer.
Water
Moderate; deep watering 1x/week in summer, less in winter; avoid waterlogging.
Soil
Well-drained, slightly acidic to neutral; tolerant of varied soils. Watch for zinc deficiency (small leaves, short internodes) in alkaline desert soil.
Sun exposure
Full sun to partial shade; excellent in containers.
