I’m in the planning process of a morris or mission style chair build that i want to keep on my deck outside. I am thinking about using cypress because it is abundant here in south Louisiana and its weather resistant. From what i understand cypress tends to expand and contract quite a bit and is also a fairly soft wood. Would these characteristics of cypress cause issues in mortise and tenon joinery? If so, should i look at another wood or should i abandon the idea of mortise and tenon joinery?

I just finished a project with cypress and M&T joints. I havent had any problems so far, and the mortises were much easier to hog out than in a hardwood. I also used acetone to clean the tenons prior to glue up to get rid of any oils that had built up. I have noticed a bit of expansion in high humidity lately but it hasnt moved too much.
