Climate plays a deciding role when determining the appropriate planting time. Newly planted trees do best when exposed to moderate temperature and rainfall and they need time to root and acclimatize before the onset of intense heat and dryness of summer or the freezing temperatures of winter. Spring and fall, therefore, are generally the best planting seasons.
In the southern United States, however, which do not experience an intense winter, planting can take place during the winter months. Palm trees are an exception: they are best planted in the warmer, summer months.

How to Prune a Tree
A tree may need pruning for a variety of reasons:
· to remove diseased or storm-damaged branches
· to thin the crown to permit new growth and better air circulation
· to reduce the height of a tree· to remove obstructing lower branches
· to shape a tree for design purposes
· to remove diseased or storm-damaged branches
· to thin the crown to permit new growth and better air circulation
· to reduce the height of a tree· to remove obstructing lower branches
· to shape a tree for design purposes
Once the decision has been made to prune, your next decision is whether or not to tackle the job yourself. In the case of a large tree where you want to remove big branches in the upper area of the crown, it may be best to hire experts. Large tree pruning, in particular, can require climbing and heavy saws or even cherry-pickers and chain saws. However, there are new tools available that can make this a manageable job.

Citrus Trees
Orange
Oranges arrived in North America from Europe but they originated in China. Orange trees generally range in height at maturity from 22 to 30 feet. Leaves are dark green, pointed with a round base and from 3 to 5 inches in length. Leaves can live for as long as three years. Flowers are white. The fruit itself is technically a berry (hesperidium) ranging from 2 to 4 inches in diameter at full size. The number of seeds in the fruit can vary according to a variety of factors with some 'cultivars' like navels being almost completely seedless.
For the home landscaper, depending on the region, there can be a wide range of orange tree varieties from which to choose.
Like all citrus trees, oranges are cold-sensitive.
If you live in northern Florida, the southern areas of the other gulf states or other regions where the occasional freeze is always a possibility during winter, think about choosing an early season cultivar like 'Hamlin', 'Parson Brown', Ambersweet or 'Washington' navel. Early season cultivars bear fruit before December unlike late season cultivars, some of which may not bear fruit until March. For advice on the best choice of orange tree for your region and climate, consult your local tree care specialist.

Old growth forest, also called primary forest, ancient forest, virgin forest, primeval forest, frontier forest or (in the UK) Ancient Woodland, is an area of forest that has attained great age and so exhibits unique biological features. Old growth forests typically contain large live trees, large dead trees (sometimes called "snags"), and large logs. Old growth forests usually have multiple vertical layers of vegetation representing a variety of tree species and age classes.
Forest regenerated after severe disruptions, such as clear-cut or fire is often called second-growth or regeneration until a long enough time passes that the effects of the disturbance are no longer evident. Depending on the forest, this may take anywhere from a century to several millennia. Hardwood forests of the eastern United States can develop old-growth characteristics in one or two generations of trees, or 150-500 years.
Old growth forests may be home to rare species which depend on this now-rare habitat, making them ecologically significant. Biodiversity may be higher or lower in old growth forests than in second-growth forests depending on specific circumstances. Logging in old growth forests is a contentious issue in many parts of the world.
