Potting-up & Cotyledons
Hi guys! A real newbie here with a real newbie kinda question: awhile back I "potted-up" to the point just below where the first true leaves were showing inside the cotyledons (had read various places where that was the thing to do). Now, some three weeks later, the cotyledons are a half inch above the soil line and the true leaves are branching out an inch above that (other branches have developed also). The cotyledons are still quite green. Question: Will the cotyledons ever wither and go away? If not, is there a certain point at which it's okay to cover them up with mix, or is it best just to leave them alone?

Sounds like a very healthy seedling that doesn't need any "help", congratulations. They will wither away when they outlive their usefulness.

And the cotyledons outlive their usefulness after true leaves are formed since now the plant can make it's own energy via photosynthesis.
The cotyledons provide energy to the plant only for a very short period of time and actually it's almost completely associated with initial germination.

Eventually the cotyledons will dry up by themselves, but I usually find that they haven't gone yet by transplanting time. It's OK to cover them with mix or even remove them first if you want to plant the seedlings deeper.
