I'd say about 2-3 weeks after germination.
I planted 5 youkon Goldern plants about a month ago. they are growing so fast. Two weeks ago, I made box to hill them. Its about 8 inches tall. I hilled them with some fertilzed top soil. In two weeks they have grown over 10 inches more.papadekaitlyn said:You can container grow sweet potatos, but you will need a large container. Also as the plant vine grows I would add more soil around it to provide more area for new roots (and taters) to grow as the plant grows.
I have grown red potatos in tire stacks quite well many times. I start with one tire and when the plant reaches about 2 feet tall I add another tire around it and fill it with soil as well as more slow release fertilizer.
I keep doing this until the vine dies and then just rip the tires off the stack one at a time and dump the potatos out.
