The seedlings are now big enough to transplant into 4″ pots.
Notice that the roots are growing out the bottom of the peat pellets. This is a clear sign that the seedlings are ready to be planted in pots.
As shown in the pictures, I place the peat pellet and plant all the way in the bottom of the pot and fill the pot with potting soil.
The pictures above are actually a couple of weeks old.
