I am new to the board. I have several morning glory vines, all are blooming nicely except one that is climbing up a fence and a small tree. Tons of healthy foliage, no blooms at all. Plenty of sun exposure, healthy looking foliage, just no blooms. I read something on this site about Epson salt, would that help?

actually, epsom salts is well known to most seasoned gardeners, although some, like me, tend to forget sometimes

however, morning glories are one plant i would not use it on. they seem to better when left to their own, and feeding them can actually cause them to vine more than flower.

on a final note, i deleted the epsom salt link because while it has some good information, the information found there can also be found here.

that i can't answer, but i am sure some one can. i don't usually cut mine back, but rather just "let them have their head"
