Fir spruce

Fir and spruce forests are greatly affected by slight fluctuations in climate. Temperature is the primary determinate for spatial patterns of fir and spruce. The two dominant trees in this type of forest are Picea engelmannii (Engelmann spruce ) and Abies lasiocarpa (subalpine fir ). If the twig carries its needles singly, it’s a good bet you’ve got a fir or a spruce. Pull off a needle, and roll it between your fingers.


If it feels flat and doesn’t roll easily, it’s a fir. If the needle has four sides an thus, rolls easily between your fingers, it’s a spruce. Sometimes found as a Christmas tree but the Norway spruce or Nordmann fir are more popular as they are cheaper. Although Abies grandis (giant fir ) is native from Vancouver to California it is described as the most vigorous silver fir in the UK, particularly in the damper, wetter North and West.


It has citrus-grapefruit smelling leaves. First, the spruce has a 4-angled needle, meaning you can roll it between your thumb and forefinger. A fir needle is 2-angled and therefore flat, so you can’t roll it. Or touch the tip of the needle. A spruce needle will be stiff, sharp and prickly while a fir needle is usually rounded or notched at the end.


Spruce is useful as a building woo commonly referred to by several different names including North American timber, SPF ( spruce , pine, fir ) and whitewood (the collective name for spruce wood).

Branches tend to be upturne but are fewer in quantity than on a spruce or a fir. Tend to grow from a single, circular area on the trunk of the tree. Cones often begin developing with a green color, then turn reddish-brown or black. Fully developed cones are stiff and woody, and certainly inflexible. While developing, cones hang towards the ground.


As I sai both of these trees are evergreen conifers. That means that they both reproduce by making cones, not flowers. On true firs the cones stand up. The exception to this is a Douglas Fir. Collectively, they are called conifers because of their cone production.


Conifers are commonly found growing in Ohio landscapes and several species are used as Christmas trees. If you see images of cones growing on conifers, firs trees are the ones where cones grow erect, not hang down. The easiest way to tell a fir apart from a spruce is to feel the needles. Pine, fir , and spruce are strongly antimicrobial, and anti-fungal.

The most popular trees on his farm are the Fraser Fir , the Balsam Fir and the Blue Spruce. The Blue Spruce is a tree that, as Leyden puts it, has a really great shape.


Fir spruce

Spruce Pine Fir is a classification of lumber which actually consists of four different wood types. There are two different spruces, which are White Spruce (Picea Glauca) and Engelmann Spruce (Picea Engelmanni). There is also Lodgepole Pine (Pinus Contorta) and Alpine Fir (Abies Lasiocarpa). Firs are distinguished from other pines by needle-like leaves that attach singly to the branches. This is in contrast to spruce trees, which have paired needles with a hinge-like base, and pine needles, which are bunched in clusters.


Fir trees are also distinguished by cones that stand upright on the branches like candles. Spruce vs pine, pine vs fir – they can all be a bit confusing at times. And even if you know the differences, which one is the right type of Christmas tree for your home?
