Propagation Methods:
Sow seed in situ in spring after all danger of frost is over and soil has warmed up.

I successfully start morning glory plants early in the greenhouse. In late April I soak the seeds in warm water for 24 hours and then plant seed in seed starting medium and place the seed flat on the heat mat in the greenhouse. Just after seeds germinate, the small seedlings are transplanted into deep pots with a soil based potting medium. They continue to grow in the greenhouse on cold days and brought outside on warmer days until late May. The plants are then brought outside to harden off. Around early June when the soil has warmed, they are carefully transplanted outdoors with as little disturbance to the roots as possible. A handful of complete organic fertilizer is mixed into each planting hole at the time of planting.

If you don't have a greenhouse start your seeds indoors about 2 weeks before last frost. Place in a bright window but take them outside for the day during warm spells. Gradually acclimate seedlings to outdoor living and when soil temperatures warm up transplant seedlings in the ground.

Pests and Diseases:
Slugs, snails, spider mites, white blister, rust, fungal leaf spots, stem rot, and thread blight may be a problem.

 

Rainy Side Notes

I don't see much difference between 'Star of Yelta' and 'Grandpa Ott'; however, I haven't grown them side-by-side for comparison. Both are beautiful deep purple with a rose star. 'Grandpa Ott’ has a rosy throat where 'Star of Yelta' has a more pronounced white throat. Both are great to grow. Some images show 'Star of Yelta' to be bluer than the flowers from my vines.

This morning glory is supposed to be an improved cultivar, the star is darker than 'Grandpa Ott' according to some sources. Mine had some variation from the same packet of 'Star of Yelta'. I will look for other seed sources to see if I can grow one that has a darker star. You be the judge.
