Growing Morning Glory in Zone 9A

Morning glories are fast-growing vines that cover a trellis in weeks, bearing trumpet-shaped flowers that open each morning and close by afternoon.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Nick or soak seeds in water for 24 hours before planting for faster germination
• Direct sow after last frost — does not transplant well
• Blooms best in poor to average soil — rich soil promotes leaves over flowers
• Self-seeds aggressively and can be invasive in warm climates
• Flowers close in afternoon and don’t open on cloudy days

Companion Planting

Good companions: pole beans, squash, corn (use on same trellis structure)

Avoid planting near: Rich, heavily-amended soil

Harvest Timeline

Ornamental; collect seeds before pods split for replanting
