A Budding Forest of Words

Spring is coming to our area. I can see small red buds developing on some of the trees.I also found some trees hiding in these words and now that's all I can see! Can you help me with the missing letters that will finish off these puzzling words? A couple of the clues have more than one answer possible. None of the answers are plural. None of the words are vulgar either.
