    A:

    According to plant and seed company Burpee, sunflower seedlings should be pruned in order to create a sturdier and more wind-resistant adult plant. Seeds must initially be planted in groups of 2 to 3 seeds. When the seedlings reach a height of 3 to 4 inches, all but one strong seedling is snipped off. Extra garden soil is then carefully filled in around the one remaining seedling.
