Why erosion control around trees matters in Hawaii Hawaii’s steep slopes, intense tropical storms, variable soils, and frequent development pressure make erosion control around trees a practical and ecological priority. Trees by themselves help stabilize soils, but bare soil under and around tree canopies is vulnerable to sheet flow, gullying, and the loss of root-protecting […]
Overview: salt spray and the Hawaiian environment Salt spray is the aerosolized seawater and salt crystals carried on wind from the ocean to the land. In Hawaii, where coastlines are ubiquitous and trade winds frequently bring ocean air inland, salt spray is a common environmental factor for trees and other vegetation. Salt spray differs from […]
Introduction Trees are among the most powerful tools a gardener has to shape microclimates — the small-scale patterns of temperature, wind, humidity, and soil moisture that determine how well plants grow. In Hawaii, where conditions vary dramatically over short distances from wet windward slopes to dry leeward plains and from coastal salt spray zones to […]
Fruit production is an outcome of a sequence of biological events: adequate flower development, effective pollination, fertilization, and successful retention and maturation of fruit. In Hawaii, where unique climates, soils, flora, and pests intersect, trees that otherwise appear healthy may still fail to set fruit. This article examines the major causes — environmental, biological, physiological, […]
Trees are a cornerstone of Hawaii’s landscapes, providing shade, cooling, erosion control, habitat, and cultural value. At the same time, water is a precious resource across the islands.
