Is it better to split freshly cut logs or wait until they've dried?

I just had a tree cut down (cottonwood if it matters) and the largest logs are around 24" diameter. I plan to use a power log splitter to split the wood but I'm wondering if I should split now or wait until next year?

now ,the propose for spliting is to let the wood dry out faster, exposes more surface area, plus it will be harder to split once it drys out,

The wood needs to be seasoned one year before burning....But you need to split it while it is green..cottonwood is not a very good fire[place wood..but if it is free as you have cut it down..I would burn it..I just wouldn't buy cottonwood to burn...

Always easier to split when fresh cut.

some split better green and some dry
cotten wood I am betting dry because cotten wood holds a lot of water like a beech or willow.

My experience is that it is easier to split dry logs but it is better to split them freshly cut for drying purposes. Try hand splitting a green log as opposed to a dry log and you will see what i mean.

Split now, they will dry better after splitting.

split now and they will really be dry and ready to use sooner.

For some reason logs split better in cold, freezing weather, but then again I split by hand with a maul. If you have a power splitter, split it green so it'll dry out faster.
