Anytime. Submerge the pot in a large bucket of water. The potting soil will fall away and you can separate them easily. Repot carefully. Or just cut off all but the tallest one, since these plants will get quite large and likely you won't have room for more than one?

when they are 5 inches tall. Plant the tree so that a 1/2 inch of root is showing so the tender green stem is high enough above the soil line to prevent damp off.

I also pull air through the roots.

Dave I will try to keep them all!! Hehehehe, just rearrange my kids! This is like my therapy! I have key lime, kumquat, Mandarin, blood Orange and lemon... Babying them all. Oh and these grapefruit. I started 7 seed and they all came up.

Congrats, Stacy!

Almost a week has passed! Growing nicely!
