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.
The original migrants came from a region in East Polynesia which MÄori later called Hawaiki. Bringing dogs and rats, taro and kÅ«mara (sweet potato) to New Zealand, they found plenty of wildlife, including birds now extinct: the moa, a species of swan, and the giant Haastâs eagle.he Pacific was the first ocean to be explored. But New Zealandâs isolated islands, in the cold south-western waters of this ocean, were the last to be settled. Migration eastwards across the vast expanse of water occurred over thousands of years.
