Neighbor just cut down a huge branch that had split in the fall on their apple tree. I got the twigs which I use as kindling. (5-7mm diameter twigs) I assumed they would be totally dry by now since the branch had been 'dangling' for 4-5 months.... When I broke a piece there was still a hint of green right beneath the bark. Is that going to make a huge difference in how well they burn when used as kindling or should I let em 'season' some more?
