Yes, this is credited to the efforts of Yavanna and Nienna, and leads directly to the creation of the Sun and the Moon (late in Season 3).
So, while that might not happen yet, there should definitely be a major effort to save the fading, dying Trees - they're not...dead...yet... until the end of the Episode. We don't necessarily have to see the last bloom/fruit, but we could see the Triage. Nienna is likely 'just weeping' and not doing anything. Yavanna is doing stuff (singing, coaxing it back to life, breathing on it?). Fëanor is...?
