Description of aspen wood Vs. alder wood
Aspen wood is a knot-free type of wood known for its woody and robust tree species. The color of the untreated aspen wood is often compared to the color of white chocolate. The drawings of the wood also provide a graceful and luxurious appearance.
Aspen trees are the most visible hardwoods in western North America, providing under-layer biodiversity, wildlife habitat, livestock fodder, specialty forest products, and highly sought-after scenery. The tree usually lives about 100 years.
Interestingly, Utah and Colorado are home to most of the world’s natural acreage aspen.
The aspen wood is very similar to the quivering poplar in terms of color, structure, texture, and mechanical properties. Aspen wood is difficult to dry and is not weatherproof.
Aspen is a real Poplar with similar characteristics and properties to cottonwood and European poplar. Medium shock resistance and deficient bending strength and bending classification
Alder wood is a relatively soft type of wood. The density of Alder wood is high, so the wood can feel a bit warmer. An advantage of a higher density is that the wood will absorb less dirt.
Freshly sawn Alder, the sapwood, which has the same color as the heartwood, has a striking orange-red color, especially on the ends, and is white on the longitudinal surface.
After being exposed to light and air for some time, it eventually turns pale yellow with a reddish to slightly reddish-brown tinge.
Red Alder is usually a bit darker than European Alder. The wood has no gloss and has dark lines caused by the wide beams. The Alder is hardy and water-repellent and does not overheat when used for the sauna.
Red Alder from North America, with almost the same properties as Alder, is used in Western Europe as a substitute for cherries in the furniture industry. Red Alder is usually a bit darker than European Alder.

Aspen Vs. Alder wood stem
The crown is thin and widely branched. The bark is gray-brown, or silvery gray, more or less smooth, but in older trees.
A straight trunk with a black-brown bark, later with deep grooves, Often there are several tribes.
Aspen wood bark Vs. alder wood bark
The bark is dark gray, rough, and in older trees, it is roughly grooved horizontally. In upright trees, more than half of the trunk is often without side branches. Young twigs are yellow-brown, shiny, and slightly drooping.
The bark is black-brown and strongly grooved. Young twigs are slightly triangular, and they bear resin glands which can make them a little sticky.
Aspen Vs. alder wood branches
Young branches are almost bare or thinly haired.
Young branches and buds are sticky (with White Alder, they are not sticky) and bare. The petiolate buds are purplish.
Aspen Vs. alder wood leaves
The leaf buds are pointed and almost bare, and the bud scales are somewhat sticky. The long petioles are laterally compressed (flat).
The first leaves on the long shots and the leaves of saplings often look slightly different. These are ovate to triangular, pointed, and have a serrated edge.
Aspen gets its name from the rattling sound its leaves make. This is because the petiole is flattened laterally transverse to the plane of the leaf itself. This causes the leaves to vibrate with a bit of wind and make a rattling sound.
The “adult” leaves are almost round to broadly ovate, nearly glabrous, have a truncated to slightly heart-shaped base, are dark green above and light gray-green below. The leaf margin is coarsely serrated and not translucent.
Young leaves are very sticky.
The spreading, slightly sticky, up to 11 cm long leaves are almost round to obovate, with the greatest width above the middle.
They are unequally serrated or serrated and usually have a wedge-shaped base and a rounded obtuse or slightly incised apex.
There are five to eight pairs of lateral veins. On the underside, they are only hairy in the vein axils (hair tufts). The leaves are green underneath.
Aspen Vs. alder wood Fruits
A capsule. The fruiting catkins with woolly hairs are 5-12 cm long. The seeds are very short-lived (less than one year). Dicotyledonous.
A single-seeded achene or nut, The fruit catkins are 1.1-1.7 cm.
The alder plugs are petiolate, conical, and lignified. The seeds are not or hardly winged. The seeds are short-lived (one to five years). Dicotyledonous.
Aspen Vs. Alder wood flowers
Unisexual. Dioecious. The spherical, pendulous catkins are 5-8 cm long. They appear before the leaves open.
The flowers have two bipartite stigmas. The male flowers contain five to twelve (rarely to seventeen) stamens. The black-brown catkin scales (bracts) are deeply incised and have long gray woolly lashes.
unisexual. Monoecious. Male catkins are elongated and yellow.
They can grow up to 12 cm long with a 1-3 cm stem. They flower before the tree comes into the leaf.
The lateral, oval, clearly stalked female flowers are reddish-brown which is Male and female flowers grow on the same branches.
Aspen Vs. Alder wood spread
In temperate and cold regions in Asia (Japan), Europe, Northwest Africa, and North & South America, Aspen trees grow singly and in multi-stem clones across the broadest distribution of any native tree species in North America.
The range of aspen trees extends from Newfoundland and Labrador west across Canada along the northern boundary of trees to northwestern Alaska and southeast through Yukon and British Columbia.
It is mainly found in the mountains from Washington to California, southern Arizona, Trans-Pecos Texas, and northern Nebraska throughout the western United States.
It extends east to West Virginia, western Virginia, Pennsylvania, and New Jersey from Iowa and eastern Missouri.
Alder wood was also found elsewhere in almost all of Europe, Northwest Africa, Asia Minor, and Western Siberia.
Aspen Vs. alder wood soil
Aspen is a pioneer species of forests on moderately dry, relatively moist, somewhat airy, sandy to loamy soils. They are found more on more acidic soil than on neutral or calcareous soil in terms of acidity.
Sunny to lightly shaded places on moderately dry to fairly wet, moderately nutrient-poor to usually relatively nutrient-rich, weakly acidic to a mostly calcareous soil.
Aspen Vs. alder wood habitat
Forest edges, scrub, thickets, hedgerows, pioneers on forests (clearings), sea dunes, roadsides, and railways.
Waterfronts, streams and riverbanks, swamp forests, and tree are mainly found on moist and not too nutrient-poor soil.
Aspen wood Vs. Alder Wood Durability
aspen wood is not resistant to decay but resistant to preservative treatment.
Both the core and sapwood are not durable (natural durability class V) and susceptible to damage by Anobium. Alder in contact with wet cement or concrete will prevent it from curling.
When used underwater, Alder lasts a very long time. That’s why it’s also best for boats or any product that is related to moisture.
Red Alder is of lower quality than that Black Alder. White Alder is often planted as a windbreak.
