Description

Maytenus is a genus of evergreen shrubs and small trees that belong to the Celastraceae family.

Taxonomic Information

Appearance

Maytenus plants have a dense, bushy growth habit that makes them ideal for hedges and screens. The leaves are glossy, dark green, and oval-shaped, with toothed margins. The branches are covered in sharp spines that deter animals from browsing. The flowers are small and greenish-yellow, and the female plants produce small, round berries that turn red or black when ripe.

Care Guide

Maytenus plants are relatively easy to care for and can thrive in a range of growing conditions. Here are some tips:

• Water: Maytenus prefers well-draining soil that is kept moist but not waterlogged. Water deeply once a week during the growing season, and reduce watering in winter.
• Fertilization: Feed Maytenus with a balanced fertilizer in early spring and midsummer to encourage healthy growth.
• Soil: Maytenus prefers slightly acidic soil with a pH between 5.5 and 7.0. Amend heavy clay soil with organic matter to improve drainage.
