Do you have to stabilize before healing?
If healing is unavailable, the creature can at least be stabilized so that it isn’t killed by a failed death saving throw. To put it slightly differently, you don’t have to stabilize someone before you can heal them; it’s a backup option if you haven’t got any healing handy.
How do I get rid of petrified condition 5e?
Petrified is a condition, there are currently two spells that remove it. Greater Restoration as mentioned here, and Wish, the 9th level spell.

How long does it take for petrified wood to decompose?
Mineral-rich water that’s flowing through the sediments deposits minerals in the tree’s cells. As the tree’s lignin and cellulose start to decay, a stone mold also begins to form!
