Occasionally you will find plants in a tray without individual cells. If this is the case, separate the plants gently by hand or with a knife. Do this just prior to planting so the roots don't dry out. For plants in individual peat pots, be sure the top of the pot is below soil level after planting. The edge of the peat pot can be torn off but DO NOT remove the entire peat pot or roots can be damaged.
All roots penetrate and grow through the peat pot.
