During the growing season, it’s essential to keep your Gladiolus plants well-watered, especially during dry spells. Provide support for tall varieties to prevent them from bending or toppling over. Regularly deadhead blooms to encourage continuous flowering. Fertilize your Gladiolus every 2-4 weeks with a balanced fertilizer to promote robust growth and vibrant blooms. Mulching can help conserve moisture and control weeds around your Gladiolus bed.
