Answer: If your morninglories are not in full sun, then that will delay flowering -- especially if you have a cool, cloudy summer. Also, if you over-fertilized the morning glories with nitrogen, the plants spend all their time producing foliage. Try not using the 12-12-12 fertilizer this year and be sure the plants get enough sun. You can even stress them a bit by midsummer by withholding water to induce flowering..
