Sowing Sow thinly into pots or trays in a good compost under glass at 21-24°C. Cover the fine seeds very thinly. Planting When the seedlings are large enough to handle, prick off into groups of 4 or 5, 5cm (2”) apart. Grow on and gradually harden off before planting in the flowering site 15cm (6”) apart. Other Instructions In hanging baskets it helps to give more depth to the display to add a few upright plants in addition to the trailing varieties.
