Answer: Morning glories will usually close in mid afternoon and in cloudy weather. Is it possible you are looking at the wrong time of day? All three of these vines take a good while to come into bloom; they love hot and sunny weather. Although the Black Eyed Suzie vine is a smaller one, the other two are potentially very large and need ample root run to do well and bloom their best. If the container they are in is small, or if they are crowded, they may be stressed for moisture and /or nutrients even though you are feeding every other week and watering every day. Try to make sure the soil is evenly moist (not soggy sopping wet and not allowed to dry out, on no account should the vines wilt) and try fertilizing according to the label directions at the highest suggested rate on the label. Next, you might try using compost as a top dressing and possibly a seaweed based water soluble fertilizer in case there are micronutrients missing from the spotting soil. I hope this helps.
