Manchineel tree: complete guide

Overview

The manchineel tree (Hippomane mancinella) is an extremely toxic tropical tree native to Caribbean islands, northeastern coast of South America to Venezuela. The plant is widely known for its caustic sap that can cause severe skin conditions, nearly chemical burning. All plant parts are toxic: leaves, bark, fruits, sap. This tree is typically cultivated as a botanical curiosity and requires considerable safety precautions. Not suitable for families with children or pets.

Appearance and bloom

The manchineel tree grows up to 15 meters tall with a dense, compact canopy. The leaves are smooth, glossy and lance-shaped, 7-12 centimeters long. Flowers are inconspicuous, small and greenish, with male and female flowers separate. The fruits are extremely dangerous: they resemble small apples of 3-4 centimeters diameter, yellow to green when ripe. This closely resembles edible fruits which is particularly dangerous. Sap can cause harm even at distance.

Ideal location

Plant only in very warm, sheltered gardens or special greenhouses. Temperature must not drop below 15 degrees Celsius. Place in completely isolated location, out of reach of children, pets and unsuspecting visitors. Ensure complete protection against contact. Ensure good drainage and full sun to partial shade. No contact with other plants recommended.

Soil

Well-drained, sandy to loamy soil is ideal. pH between 6.0 and 7.5. Add extra sand and potting soil for optimal drainage. Avoid waterlogging absolutely.

Watering

Water carefully and regularly during growing season. Allow soil to partly dry between waterings. Avoid waterlogging absolutely. Do not use regular plant care workers without explicit warning.

Pruning

Minimal pruning without exception. ALWAYS wear protective gloves, eye protection and complete body coverage. Stop work at slightest sign of skin irritation. Wash thoroughly with copious water after contact. Do not delay in rinsing.
