No answer to the Bermuda grass question.

Random other question. Do some cactuses grow really slowly? Last year I threw dragon fruit seeds in a pot and 8 sprouted. They are now about 1.5 inches tall. That’s it. Eventually, a dragon fruit tree should be perhaps 5 feet tall. At this rate of growth, I’ll be passing on this plant in my will before it ever grows up and has fruit.

I did mush the same as you several years ago and had my Pitaya plants in my greenhouse, but they didn't grow well. I replanted several of the longer sections in a mixture of manure and potting soil and I placed them under an oak tree. They have been growing very fast.
Dragon Fruit cactus are a plant from the dry tropics and like shady locations. I keep the basal roots and soil moist. The plants also like to climb brick walls.
