Stuff in my new yard is running low on life span...?
What do I do to replace things? One spice tree has 0% life span. Do I have to kill it with wine form the Hell Bar and replace? I'm sure that there is a place to find this info, but I'm not talented (or patient) enough to find it.
For patches, you have to poison the tree before you can restore the patch. Everything else will have a project available to restore it once it reaches 0%.
You shouldn't need to poison it. It should die once you've harvested everything from it after it reaches 0% (at least that's how it always works for me). Then chop the stump and you can either renew or remove the broken patch.
