"data exception: string data, right truncation" on INSERT with prepared statement

When attempting to execute a preparedStatement with parameters in this code

public void Insert(String TreeType, String LastWatered, String PlantDate) {
    try {
        String G = "INSERT INTO Trees (TreeType, LastWatered, PlantDate) VALUES 
(?, ?, ?)";
        PreparedStatement preparedStatement = conn.prepareStatement(G);
        preparedStatement.setString(1, TreeType);
        preparedStatement.setString(2, LastWatered);
        preparedStatement.setString(3, PlantDate);
        preparedStatement.executeUpdate();
    } catch (SQLException ex) {
        Logger.getLogger(TreeArr.class.getName()).log(Level.SEVERE, null, ex);
    }

}

I get this error

preparedStatement.setString(1, "Hello World");

How can this be done be acheved?

data exception: string data, right truncation; table: TREES column: TREETYPE

The error message is telling you that the string value in the Java variable TreeType is longer than the maximum allowable length of a string in the column TreeType as defined in the Trees table. You'll either have to make the column wider or make your string shorter.
