Garden Soil

Soil Type

Water: Tropical ash thrives in humid, tropical conditions and has a balanced water requirement. Watering every 1-2 weeks maintains its health. As an evergreen, it retains leaves year-round and needs consistent moisture even during dormancy.

Fertilize: For optimal care of tropical ash, use balanced fertilizers, emphasizing high nitrogen types during growth. Apply quarterly in the growing season, reducing in cooler months. Proper measurement and thorough watering post-application prevent root damage. Wear gloves and follow label directions for safe feeding.

Pruning: Tropical ash grows rapidly and develops a dense canopy. Pruning should focus on removing dead branches, thinning crowded areas, and shaping for structural integrity, ideally in early spring. Regular pruning helps control size, strengthens branching, reduces storm damage risk, and promotes healthy growth.

Propagation: Tropical ash, from the Oleaceae family, is a fast-growing species ideal for warm climates. Propagate using healthy, semi-hardwood stem cuttings with rooting hormone. Place in well-draining soil under high humidity and indirect light, then gradually transition to their permanent location for optimal growth.
