Yes I too think 3/4" a bit much.

Most importantly this will affect the direction you place the root, up or down. After first emerging the root does a 180, so at a venerable 3/4 of an inch it has already done the turn and needs to be planted face down, where as a brand new sprout needs to be planted with the root pointing up.

Of course as a "weed" it will likely recover from any injustice visited upon it during this process and therefore "It is all good"
