Dried bud and sugar leaves q

Hey, i have a load of super dried crispy sugar leaves and buds, so crispy they sort of flake into dust when you hold them. (they were left out for a few weeks)
Can i still decarb these or will they just burn? Should i add some moisture in with lettuce leaves first?
Thanks!

Decarb them dry but cover in foil to avoid scorching.

i dont think you add moisture, you just need to decarb themand as has allready been said by anexgrower cover them and decarb at say 154 degrees c 310 f for 7 mins will decarb it acording to my book on growing autos

That's ok the drier the better for extraction. They are viable for any extraction you are looking to do: Bubble, Dry Sift. BHO, Cannabutter, etc.
