Seedbed growth :
With proper spacing between seedlings ( > 1 cm), leave seedlings to grow to 10 cm high.
If spacing is too small, separate seedlings once they reach 3 to 4 cm high and grow in individual pots.
Small plants can be transplanted once they reach a hand’s length ( (10 to 15 cm high).
Plants are hardy once about 10 leaves have formed and they can survive in a small space before being planted out.
