How to Grow Jubilee

Jubilee sweet corn is a popular warm-season hybrid that delivers tender ears in just over two months. Gardeners prize this variety for its reliable yield, disease resistance against common blights, and ability to thrive in full sun across most growing zones.
📷 Wikimedia CommonsStarting Jubilee: indoors or direct sow?
🌾 Sow directly in the garden — Jubilee is not usually started indoors.
Do not start indoors; sow seeds directly into the garden once soil temperatures are warm enough following the last frost date.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 6.8. As a warm-season crop, plant seeds directly outdoors only after the last frost when the ground has warmed up. Sow seeds about one inch deep; they typically sprout within seven to ten days provided temperatures remain consistently high.
Space plants eight to twelve inches apart in rows spaced three feet apart. This tall variety does not require trellising but benefits from consistent moisture, especially during pollination. Apply mulch around the base to retain water and feed regularly with a balanced fertilizer every few weeks to support heavy ear development.
Watch for corn earworms, borers, and rootworms; use row covers early or apply organic sprays if infestations appear. Prevent leaf spots and rust by ensuring good air circulation and avoiding overhead watering. Harvest ears when the kernels are milky, typically 85 to 90 days after planting.
