Grandpa Ott Morning Glory Seeds

Direct sow Grandpa Ott Morning Glory seeds after your last frost date, as they hate being transplanted. Before sowing, soak the seeds in warm water for 12-24 hours, or nick the seed coat lightly with some sandpaper. This step will cut the time to germinate noticeably. Sow purple Morning Glory seeds 1/2 inch deep in the warm soil. Soil temperature should be at least 60°F, otherwise the seeds will just sit there. Under good conditions, Grandpa Ott Morning Glory seeds germinate in 5-21 days.

Purple Morning Glory flower require full sun for heavy blooming. In partial shade, forget  about the blooms, they’ll get foliage instead. Soil type is not as important as drainage, and Ipomoea Purpurea does better in poor, average soil than rich, bedded soil. Too much nitrogen, and they’ll just get leaves. Water them well until they’re established, then cut back, as they have good drought tolerance once the roots are established.

The plant is low-maintenance and will take care of itself once it gets started. Still, it's best to put in a support system before the Morning Glory vines need it, as the tendrils of the plant grab fast, and redirecting established growth is a losing battle. Deadheading is not necessary if you want non-stop blooming, but if you want to harvest seeds at the end of the season, allow a few pods to mature and dry on the vines. A note of caution: all parts of the plant are toxic if ingested, so if you have children or pets, this may not be the best choice to grow in the garden.
