I planted morning glory in my balcony garden. Of course, it’s for eating.

I don’t know how many ways to plant it, but I use the easy one; buying morning glory from the market, choosing those that have roots, cutting them about one finger length from the roots, and then putting them into soil.

Some grow in three days, some take about five days, and some take longer. 

According to this, I conclude that morning glory takes between seven to ten days to give the sprout.
