Answer: Some trees and shrubs require acidic soil pH (below 7.0) or they will develop iron chlorosis. Examples include river birch, blueberries, azaleas and rhododendrons. While it is easier to work with plants adapted to your current soil pH, there are amendments you can use to make your soil more acidic.
Under the leadership of British statesman Edward G. Wakefield, the first British colonists to New Zealand arrive at Port Nicholson on Auckland Island. In 1642, Dutch navigator Abel Tasman became the first European to discover the South Pacific island group that later became known as New Zealand.
Before 1840, there were about 2000 Pakeha (Europeans) in New Zealand, most living in the Bay of Islands. At this time, intertribal Maori warfare was frequent, and the arrival of guns, which Maori traded from Pakeha, made it deadly.ith growing numbers of British migrants, and a dwindling and largely landless Maori population, British culture dominated New Zealand life throughout the 19 th and first half of the 20 th centuries. However, since World War II, New Zealand has moved towards its own unique national identity and place in the world.
