Is it heavy? Is it light?
How does it hold up?

The Good About Catalpa Wood

Rot Resistance

Catalpa heartwood has natural resistance to decay.

Fence posts made from catalpa are known to last a long time in the ground — sometimes decades.

Lightweight and Easy to Work

The wood is soft and relatively light, making it easy to cut, carve, or shape.

Tools don’t dull quickly, and hand carving is pleasant.

Distinct Appearance

Catalpa has a coarse, straight grain and a light to medium brown color.

Some woodworkers find it visually interesting, with a rustic look.

Low Shrinkage

It seasons (dries) without much warping or cracking compared to some other woods.

?? The Bad About Catalpa Wood

Softness / Weakness

It’s relatively soft and not very strong structurally.

Not suitable for load-bearing uses, fine cabinetry, or flooring.

Limited Commercial Use

Because it’s not widely harvested or standardized, you won’t find it at lumberyards.

That also means it’s not well-documented for large-scale applications.

Coarse Grain and Porous Texture

The grain can be uneven, with open pores, making it harder to get a smooth, polished finish.

It can look “rustic” but not refined if you want a sleek furniture surface.

Variable Quality

Catalpa trees grow fast and often irregularly, so boards can be knotty and inconsistent.

That's pretty tough. You never see a woodpecker buying chapstick.

If these are the trees with the worms, I’ve never thought they would look like they would make good lumber for building, etc.

The trees are usually scraggly looking. Surprised you could get any good cuts, or volume out of one tree

That's because most in the south are topped to keep a lower canopy for harvesting worms for fishing.

You need to do something about that huge blackhead on your face.
I just saw a catalpa telecaster body that looked really cool.

The catalpa groupies are something else. I have to keep a low profile.

Admittedly though, I never heard about their lumber or the quality thereof. I'm only into them for the worms.

I know catalpa worms are laid by moths then when the leaves are ripe, then they eat every leaf, crap all over the place then turn into moths.

You freeze them in corn meal in ziplocks? That's the way my dad always did them.

I guess you can put them on anything. They have very tough skin.

I do. This isn't my pic, but how it's done.



I've noticed some guys are vacuum sealing them these days with success. They get crazy and "pickle" them for lack of a better word and even dye them pink or extra chartreuse.
