How to Grow Morning Glory and other Ipomoea Plants in the Garden

It is best to grow morning glory in their final location outdoors. Sow the seeds at a depth of 6 mm in a sunny area of the garden a couple of weeks after the last frost of spring. Ideally the soil that morning glory grows in will be moist and of pH 6 to 7.5; not to high in nitrogen or this will lead to straggly plants. Ipomoea Plant Germination takes from one to three weeks, and can be enhanced by first chipping the seeds and imbibing in hot water for a day prior to sowing.

Caring for Morning Glory (Ipomoea Plants)

Once the young morning glory seedlings have emerged they should be thinned to be about 30 to 45 cm apart, and given a trellis to climb upon. Once morning glory starts to climb on the trellis, pinch back the growing tips to encourage branching growth.
