When selecting trees to have planted on your property, you must determine what the purpose will be, and if the area you would like to plant has the correct soil type. Examine the intended planting space for good soil drainage, adequate sunlight and sufficient space to accommodate the desired evergreen tree at its mature size. Allow for clear access to driveways, sidewalks and entryways. Determine whether the tree's growth will affect any overhead utility lines.
The trees that you are selecting may be used as screening trees in order to provide privacy from your nosey neighbors or peeping Toms.Evergreens retain their leaves all year round as opposed to deciduous plants which lose all their foliage for a proportion of the year leaving them bare. Old leaves shed soon after the new leaves appear. Leaf persistence lasts for one to five years in some cases with the Great Basin Bristlecone Pine lasting up to forty-five years.
Evergreens provide wonderful year round interest whether in the countryside national parks of Sierra Nevada where magnificent Giant Sequoia grow or the humble dwarf conifers in your own garden. For the gardener, they also provide essential structure or 'bones' of garden design. Choosing the right evergreens will give you long-term enjoyment with the satisfaction of easy care. Choose the wrong evergreen and you will have a constant battle controlling its growth!
In regions with cold or dry seasons there are good survival reasons for a plant being deciduous. The existence of evergreen plants usually indicates an adaptation to low nutrient levels. Deciduous trees, for example, lose their nutrients whenever they drop their leaves. It is essential for the tree to replenish these lost nutrients from the soil so as to build new leaves and promote growth.In difficult times when hardly any nutrients are available, evergreen plants have a distinct survival advantage. Though their leaves and needles must be capable of withstanding cold including severe drought, they are less efficient at photosynthesis (The process used by green plants to turn the energy of sunlight into chemical reactions that convert carbon dioxide into oxygen and also produces sugars that feed the plant).
In warmer climates with both poor soil and ground conditions, some evergreens such as pines and cypresses species grow very well.
