Grain/Texture: Straight grained with a fine to medium texture.

Endgrain: Large resin canals, numerous and evenly distributed, mostly solitary ; earlywood to latewood transition abrupt, color contrast high; tracheid diameter medium-large.

Rot Resistance: The heartwood is rated as moderate to low in decay resistance.

Workability: Overall, Loblolly Pine works fairly well with most tools, and it glues and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Working with pine has been reported to cause allergic skin reactions and/or asthma-like symptoms in some people. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

    I had 6 acres of Loblolly pine trees in Bastrop that burned in the fire of 2011. My land should have been harvested long before the fire to allow new growth. The Feds wouldn’t allow us to clear any land “in case an extinct Houston toad was there”. They never found one Houston toad in 30 years anywhere around this area. The four year drought had killed 20% of my tall pines that turned into fires reaching 1800 degrees. We had no fire breaks either including none on both sides of the electrical power cables (this is what caused the fire when dead trees fell against the power lines showering the ground with sparks during high winds.

    The Loblolly Pine wood is heavier than what you buy at the big box stores. It is strong but still will come under attack from insects.

    There seems to be some idea that this particular species hardens to some miracle hardness like steel although I tend to think it’s not a huge difference between it and other yellow pine species. Is this mostly myth or fact?

      It is quite durable wood, however it isn’t that much different from any other type of yellow Pine. It’s reputation for hardness, strength, and durability probably came from people comparing it to the white pine commonly used as building material.

      I work with reclaimed Southern Yellow Pine and this stuff is STRONG and hard. Big difference in my opinion
