I second the use of chopsticks as an aid in transplanting seedlings to minimize root damage. I also try to gently remove any large amounts of excess soil that has clumped to root but I do like to leave some...especially if the seedling's roots are well developed.
I also echo the Santa Rita comment. I've got a couple of these that got me good on initial planting...but once established they have really taken off and I've forgiven them
