Growing Morning Glories:
How to Grow Morning Glory Flowers Organically

Growing morning glories in containers or flowerbeds adds height and color to your summer garden. These quick growing annuals can fill a trellis or scramble up a tree trunk in a matter of weeks. They have heart-shaped leaves and funnel-shaped flowers that open in the morning and last a day. The Ipomea alba or Moonflower gives you flowers that open in the evening lasting until the next morning’s sun.

Morning glories are harmful if eaten.

Help germination by making a small cut in your seeds or soaking them for twenty-four hours before planting. Morning Glory seeds are planted at a depth of 4 inches (10cm) which is deeper than many other annuals.

If your area suffers from frosts in early to mid spring, start plants indoors. Harden plants off when the last threat of frost has passed.

If you live in a warm climate, sow directly into the soil adding a fine mulch of compost with an organic fish, blood and/or bone fertilizer added.

Standard flower watering guidelines apply.

As climbers, morning glories need flower supports to grow. These can be arches and pergolas as well as shrubs and trees, so before planting, figure out where your garden will benefit from additional height and color.

Pinch off dead leaves and flowers over the season to keep the plant’s appearance in good shape.
