Answer

I'm not quite sure what you are trying to say, but:

"The smaller trees are more likely to be taken in on rainy days."

or

"The younger trees are more likely to be kept in on rainy days."

Answer

I think what you mean is the little trees are more likely to survive during the rainy season. If you plant trees during the dry season, they might not live, but if you plant them during the rainy season, they're more likely to live/survive.

Answer

It's still not clear whether you mean:

"The trees are more likely to stay ALIVE if it rains"

or

"Little trees will suffer if they get too much rain."

Please can you clarify what you mean in the question.
