We've done the recommended trenches, etc. Growth has been HUGE! We've added soil on top of soil on top of soil and the tops keep rising. Do we stop adding soil now or keep going?

In the photo, the soil is about even. But when we started the potatoes, the trenches were significantly lower than that to the left of the potatoes. Now it's had several applications of soil and is a few inches higher than that to the left. We have several inches left in the container to add soil, but wondering if it's a fruitless effort.

Thanks!
