Is hilling really necessary? It's a lot of work, and I don't see any particular results.
Hilling is the most important agricultural technique that promotes the formation of additional roots in plants, the preservation of moisture, and does not allow the root system to overheat in extreme heat.
But, really, you will not see any positive result if you huddle with dry, hot soil.
This is done in the morning after watering, when the soil is no longer sticky, but has not yet dried out. Hilling is useful for potatoes, cucumbers, cabbage, tomatoes, peas, beans. It is especially important to huddle (and higher) garlic on greens, asparagus, leeks - those plants that value a long bleached leg.
