Ponderosa Pine
Pinus ponderosa
Also called: Western Yellow Pine, Blackjack Pine, Bull Pine, Rock Pine, PP/LP (when mixed with lodgepole pine)
About the name “Ponderosa Pine”
Ponderosa pine is often sold as western yellow pine. It is a different tree from the southern yellow pines of the Southeast, which are much harder and more resinous, so check which one you are buying.
What Ponderosa Pine looks like
The wide sapwood is pale yellow to nearly white, and the heartwood is a light reddish brown. Knotty boards show plenty of dark, round knots, which is the classic knotty-pine paneling look.
Grain and texture
Straight grain with a medium, even texture. Growth rings are softer and less contrasting than in the southern hard pines.
Working Ponderosa Pine: planing, cutting and gluing
Soft and light, so it cuts, planes and sands with almost no effort. Knots can chip out or loosen, and resin can gum up blades and sandpaper, so keep tools clean. It holds nails and screws well and glues without trouble.
Finishing Ponderosa Pine: oil, film finishes and epoxy
Stain blotches easily, so use a conditioner, gel stain or a dye. Seal knots and resin pockets with dewaxed shellac before a film finish, or the pitch can bleed through. For epoxy, wipe resin pockets with mineral spirits, seal coat the whole piece, and expect the pale wood to yellow over time.
Durability, stability and Florida humidity
Low decay resistance, and termites go after it, so keep it indoors or pressure treated outside. It is fairly stable once dry. In Florida it is an indoor wood; acclimate boards in your house for a week or two before building.
Shop notes from our Fort Myers shop
Ponderosa is the knotty pine of cabins, wall paneling, doors and window frames, and it makes friendly, inexpensive furniture and shelving. It dents easily, so plan on a durable finish for tabletops. It is soft enough for beginners to learn on. We don't stock it, but ask us and we can often source it.
