Enter the first five digits of the ZIP code below: The Plant Hardiness Zones divide the United States and Canada into 11 areas based on a 10 degree Fahrenheit difference in the average annual minimum temperature.
(The United States falls within Zones 2 through 10). For example, the lowest average temperature in Zone 2 is -50 to -40 degrees Fahrenheit, while the minimum average temperature in zone 10 is +30 to +40 degrees Fahrenheit. Suggested hardiness zones have been indicated for all trees and perennials available online from the Foundation. Keep in mind that local variations such as moisture, soil, winds, and other conditions might affect the viability of individual plants. You may want to ask a local professional arborist or nursery about which trees to plant in your community. Webmasters: Tree Planting - How to Plant a Tree. While planting each of these different types of trees differs in the details, all trees eventually end up in a hole. But not any old hole will do. The most common mistake when planting a tree is a digging hole, which is both too deep and too narrow. Too deep and the roots don’t have access to sufficient oxygen to ensure proper growth.
Too narrow and the root structure can’t expand sufficiently to nourish and properly anchor the tree. As a general rule, trees should be transplanted no deeper than the soil in which they were originally grown. When digging in poorly drained clay soil, it is important to avoid ‘glazing’. Planting Balled and Burlapped Trees. Balled and burlapped (B & B) trees, although best planted as soon as possible, can be stored for some time after purchase as long as the ball is kept moist and the tree stored in a shady area. Top Planting Container Trees. Once carefully removed from the container, check the roots. Planting Bare-Rooted Trees. Peacekeepers plant trees in Côte d’Ivoire to fight climate change. 30 November 2009 – United Nations peacekeepers planted nearly 600 trees in a botanical garden in Côte d’Ivoire over the weekend, a small but symbolic step in a project to combat climate change that has already surpassed its target of 7 billion trees – one for every person in the world.
The planting in the town of Bingerville follows a similar ceremony in neighbouring Liberia where UN blue helmets planted 1,000 trees earlier this year as part of the initiative launched by UN Environment Programme (UNEP) to plant 7 billion trees by the end of 2009, a goal it reached in September. With the destruction of natural forests emitting more greenhouse gases every year than the transport sector, planting trees – which absorb carbon dioxide and store nearly 300 gigatons of carbon in their biomass – provides a crucial defence in the fight against global warming.
