If you are using plantable peat pots, tear them to allow the roots to easily break through the sides. Also, tear off the top rim of the peat pot. This prevents the peat from being exposed to the air where it will act as a wick and draw moisture away from the soil ball, drying out the plant. Set the plants at the recommended spacing and cover them with soil to the depth of their container. Firm the soil around the roots and water immediately.
Most plants respond well to pinching at planting time.
Pinching, or removing the early flowers, allows the plant's energy to be used to establish the plant rather than support flowers. Pinching also induces branching which will, eventually, increase the number of flowering stems. Be sure the water penetrates to the root zone. Generally, hand watering is not adequate to supply sufficient and uniform amounts of water. Soaker hoses or sprinklers are more satisfactory watering methods.
