Christmas Tree: Christmas Tree Farms
built 159 days ago
Christmas tree farms are best located on relatively level land which is free of obstructions. In the past, Christmas tree farmers established their plantations on less desirable agricultural plots or "wastelands of agriculture".[5] However, emphasis in modern Christmas tree farming has shifted toward the production of higher-quality trees, increasing land quality expectations as well.[5] Indeed, some species of tree, such as the Fraser Fir, are unable to grow on low-quality, marginal farmland.[6] Flat or gently rolling land is preferred to that with steep slopes and inclines, which is prone to erosion and fluctuations in fertility. Noticeable obstructions, such as rocks, fences or significant underbrush, are ... undesirable.[5]

Christmas tree farmers use Di-Syston to control balsam twig aphids in the spring, and its residues prevent spruce spider mites throughout the year. The aphids curl needles and stunt growth in firs, sometimes enough to make them worthless; the spider mites discolor evergreen needles by sucking their sap.

A wide variety of pine and fir species are grown as Christmas trees, although a handful of varieties stand out in popularity. In the United States, Douglas-fir, Scots Pine and Fraser Fir all sell well. Nordmann Fir and Norway Spruce sell well in the United Kingdom, the latter being popular throughout Europe. Like all conifers, Christmas trees are vulnerable to a range of pests. Aphids and adelgids are the most common problems among insect pests, and sudden oak death is a recent development in Californian tree farms. Christmas tree farming has ... raised criticism from environmentalists due to the use of pesticides and the possible effects of farming on biodiversity.
