Thanks! I have a follow-up question: What about leaves that look dead, either on the ground or still attached to the tree? When a leaf is dead has been discussed before but maybe this needs some guidance. Some examples of leaves observed before new growth resumes:
Oak leaves that have persisted on the ground through winter observed in March:
Are these “colored” or “no live leaves”?
Or this beech tree observed in March:
Is that still “colored” or “no live leaves”?
