The best time to plant Jessica gladiolus bulbs depends on your climate and growing conditions. In general, gladiolus bulbs should be planted in spring after the threat of frost has passed and the soil has warmed up. In colder climates, this may be in late April or early May. In warmer climates, you may be able to plant earlier in the spring or even in the fall.
Jessica gladiolus bulbs should be planted about 4 inches deep, with the pointed end facing up. They prefer well-draining soil and full sun, but can tolerate partial shade. Regular watering and fertilizing can help ensure healthy growth and vibrant blooms.
Overall, the best time to plant Jessica gladiolus is in the spring, after the danger of frost has passed, when soil temperatures have warmed up, and when there is enough time for the plants to grow and bloom before the end of the growing season.
