Value Plug Plants - These larger cell grown plants will develop very quickly once planted in 7 to 9cm pots. Ease them from their tray using the dibber stick provided, pushing through the base hole of each cell, then plant into the centre of the pot ensuring all the roots are covered but that the stem and leaves remain exposed. Alternatively, plant into trays of compost. Begonias and impatiens should ideally be grown on at a minimum temperature of 18°C (65°F). For other plants 16°C (60°F) would be suitable.
