Make sure you foster a culture of asking dumb questions. It should be clear to all of your developers that they should ASK whenever they are stuck, or don't know something, or when they need a rubber duck. We have a "stupid questions" chat channel at work, and juniors and seniors alike are expected to use it when they need advice. If new developers see everyone putting their egos aside and asking for help, they are likely to follow suit.
