Transplanting seedlings without shock

A well-grown, properly hardened-off seedling can still stall badly from a rough transplant. Getting the move itself right is a separate skill from growing the seedling.
Timing it right
Transplant on a cloudy, calm day, or in the evening — never in full sun during the hottest part of the afternoon. Roots have not re-established their connection to the soil yet, so any extra stress in that window compounds.
Prepping the seedling
Water the seedling well an hour or so before transplanting. A moist root ball holds together as one piece when it comes out of the pot; a dry one crumbles and tears fine roots in the process.
Handling roots gently
Lift and hold seedlings by a leaf or the root ball itself, never by the stem — a bruised leaf grows back, a crushed stem kills the plant outright.
Settling it in
Dig a hole a little deeper than the root ball. Tomatoes are the exception worth knowing: bury the stem deeper than it was growing, since it roots readily along any buried stem section for a stronger plant. Backfill, firm gently, and water in immediately to close air gaps around the roots.
