hugelkultur bed with pinus radiata

Hi, I'm from the Canary Islands, the dry side (south). Avocado small-scale cultivation and I would like to save some water.I took some time thinking about a hugelkultur bed.
pinus radiata have much available to do it, but I read that pine is not ideal for this purpose. the wood is about 9 years ago so this pretty broken, you think I should? or better look for another type of wood.
excuse my language

Wood that old should be fine. Half the point of hugels is to create fertility from your land without many outside inputs, and if that is what you have available, I say go for it. If you can get hold of some newer stuff and some different varieties of organic matter to mix that would be great too. Somethings always better than nothing in a situation like this so don't over think it....just do it!
