Do they need to be propped up?
My elephant ears seem to be wanting to lean over. Is this normal? They are starting to grow and are about 2 feet tall.
From this image they look healthy and strong.
Could you be describing leaning over as wilting?
They may appear to wilt or lean if they are needing a drink of water.
You can add a slow release fertilizer to the soil.
