Baby's Breath and Snapdragons

Yesterday, I worked each tray of Baby's Breath, watering, replacing any plants that died an untimely death, finding then a new home in the greenhouse, in community with their own kind.  The same with Snapdragons.  Baby's Breath needs little more than water and sun from now until they are planted in their final resting place.  Snapdragons, on the other hand, need to be pinched back when they are the right size.  What is the right size?  Well, some commentators say when they have 4 to 6 leaves.  Some say when they have 4 or 5 pairs of leaves.  Hmmmm????  Mine have two or three pairs of leaves, but are too small to pinch back.  There is not enough space between the leaves to pinch anything.  And when I transplanted them, I set them in the dirt up to just under the sets of leaves.  So.....I am going to go with the second set of instructions, and let them grow a bit.  By the way, I had lots of Snapdragon seed that I collected from last year, so I planted lots.  I think every seed came up.  Thicker than hair on a dogs back!  I have transplanted them until I am running out of containers and places to put them.  Marlys, a neighbor who is a Master Gardener, says you must become a plant murderer.  OK.  Look out Snapdragons - here I come!
