Monster morning glories

I was going through my old videos and found this one of the first house I bought. It had a pool with some overgrown planter below it, so I tore out the old vegetation and put in a retaining wall. I heard that morning glories were vines that had good looking flowers that new blooms every day. Went to the Bentonville compost facility and picked up a truckload of compost for about $6 and a pack of seeds from Walmart.  At the end of spring only a few plants had sprouted, so I left the planter mostly compost. As the summer went on, the combination of compost and splash water exploded the few plants that were there into a 10'x30' heap of vegetation.
