Hackberry

Overview

Hackberry is a plain, coarse-textured eastern hardwood that looks like ash and is built like an elm. Wood Database calls it among the very best steam-bending woods of the United States and Canada. It is a utility timber, inexpensive within its range, and worth a look for bent parts, rustic furniture and turnings.

Pros

• Superb steam bending, according to Wood Database, which rates it reputed to be among the very best native hardwoods for bending.
• Generally good working characteristics with hand and machine tools; glues, turns, stains and finishes well.
• Inexpensive: sold as utility lumber at a modest price within its natural range.
• Looks similar to ash and is sometimes used in its place.

Cons

• Non-durable to perishable, and susceptible to fungal discoloration and insect attack.
• Susceptible to blue-gray fungal staining if not processed promptly, so ask how the stock was dried.
• Moderate hardness only (880 lbf) and a very coarse, uneven texture.
• Not widely available outside its natural range; small pieces with knots and interlocked-grain sections can be hard to machine.

Variants and subspecies

• Hackberry (Celtis occidentalis) and sugarberry (Celtis laevigata): Wood Database says the two are sold interchangeably.
• Spalted or stained hackberry is sometimes sold at an increased price.
• Heartwood vs sapwood: light brown to gray heartwood with a wide, light yellow sapwood.
• For elm-like species with a similar wavy pore arrangement see American elm.

Working and finishing

Wood Database reports good results with hand and machine tools, though smaller pieces with knots, or sections with interlocked grain, can cause trouble. It glues, turns and stains well and bends superbly. Process and dry it promptly to avoid blue-gray staining; keep sticker spacing even while drying.

Staining and finishing colour

It stains and finishes well. The very coarse texture and large earlywood pores show strongly in stain. The wide yellow sapwood contrasts with the gray-brown heartwood, so many people let the contrast show with a clear finish; stain narrows it. Fungal staining shows up as blue-gray and is hard to remove.

Sustainability and handling

Wood Database states hackberry is not listed in the CITES Appendices or on the IUCN Red List, and Wikipedia's taxobox shows Least Concern for Celtis occidentalis (checked 2026-09-30). Wood Database reports hackberry has been reported to cause skin irritation. The US National Cancer Institute reports strong and consistent associations between wood-dust exposure and cancers of the nasal cavity and paranasal sinuses, so extract dust and wear a respirator. US-grown timber falls under the Lacey Act.

Popular projects

Wood Database lists furniture, boxes and crates, veneer, turned objects and bent parts. Steam-bent chair parts, rustic tables and shop furniture are all natural uses.

Buying notes

Mostly found in the Midwest and Southeast at local sawmills. A national retailer, CR Muterspaw, lists 4/4 hackberry at $3.80-4.10 a board foot. Ask how recently the lumber was sawn and dried to avoid blue-gray stain. Wood Database says spalted or stained boards cost more. Treat it as an inexpensive substitute for ash or elm in non-structural indoor work.
