I've Developed a real bad Allergy to Cedar and have projects I make ans sell on Etsy

Are there any other Long lasting types of wood that I can use instead of Cedar?

Tupelo.

I sided a house with cypress not to long ago and was impressed with it. Resisted cracking well. It did have tons of energy in it though and would go wild in the table saw.

What about Cherry?

Catalpa and locust last well for outside projects. Catalpa is very lite.

Locust, Cypress and Osage Orange all last well.

I do quite a bit of wood carving, and have used a number of types of wood depending on the project. I do use a lot of cherry, ash, elm, hackberry, even black walnut. As you probably know, green (fresh) wood carves easier, but depending on the project, it may split or crack as it dries. Sometimes when the project is almost done, I will put it into a microwave for a minute or two (even up to 6 minutes on some things). Usually the microwave dries from the inside first and is so rapid that the wood does not have time to crack. So far this year I have carved 318 spoons and 27 bowls, as well as other individual projects. I tell people that I spend a lot of time spooning. It usually gets a laugh.

I make and sell Suet feeders out of
2 x 8 cedar.... but now with how bad I react to cedar I will have to Quit making them.

Redwood holds up to being out in the weather well. Teak would also hold up.

aspen will work good for that

or basswood

Those are both good woods. Teak is very expensive.

Any wood that is used in boat construction should work. American white cedar (often called juniper in Eastern NC) is very light, strong, and rot resistant. It is not at all aromatic like red cedar. In the 1800s and early 1900s it was harvested for wooden shingles. Many coastal homes are still sided with it. Makes great outdoor furniture too.

Tamarac would be my recommendation ! Native species probably available at a local sawmill.

Long lasting, oak, Tamarack.
Easy to work with, basswood,Aspen.

There’s been some really good suggestions, right now I’d look at ash as it’s quite plentiful now in a year or two it won’t be.
