Loquat Tree Care: Growing Japanese Medlar for Fruit & Ornamental Value

The loquat (Eriobotrya japonica), or Japanese medlar, originated in southeastern China and spread to Japan, Hawaii, and beyond. Today Japan and Brazil lead commercial production. This small evergreen tree (10–30 feet) with a rounded crown and lanceolate leaves (5–12 inches long, glossy green above, rusty-hairy below) doubles as an ornamental and fruit bearer.

Climate Requirements

Thrives in mild-temperate to subtropical zones. Tolerates 12°F but suffers below that; buds die at 19°F. Summer heat with dry winds causes leaf scorch.

Flowering & Fruit

Sweetly fragrant white flowers appear in late fall/early winter with a rusty-woolly texture before opening. Pollinated flowers form 1–2 inch pear-shaped to round fruits in clusters, orange-yellow to red-blushed. Thinning flower clusters improves fruit size; bagging clusters protects from birds and sunburn for premium quality.

Common Diseases

Fire Blight (Bacterial)

Wilts foliage, browns branches, gives a scorched appearance. Control by pruning infected parts with sterile shears and applying copper sprays at bloom.

Phytophthora Root Rot (Soil-borne)

Prevalent in wet, poorly drained soils. Symptoms: yellowing foliage, wilting, loss of vigor. Manage with improved drainage, careful watering, and fungicides.

Verticillium Wilt (Fungal, Soil-borne)

Causes leaf scorch, yellowing, stunted growth, stem weakening. Fungicides ineffective; replace with resistant varieties.

Planting & Establishment

• Select a healthy 4-foot sapling, pest/disease-free.
• Choose a sunny site with fertile, loamy, well-drained, neutral-to-acidic soil.
• Clear grass/weeds, dig a wide, deep hole, spread roots, backfill, firm gently.
• Water every other day for 2 weeks, then twice weekly for a month (skip if rain).
• After 4 years, water only during dry spells or fruit ripening.
