Upon receiving your plants, pot them out and grow them on in a warmer, frost free area, in order to transplant later. To stimulate branching & growth into a bushier plant, pinch out the growing tip of each stem. This will also help the plant produce more flowers. Once the risk of frost has passed, progressively allow the plants to become accustom to the outdoors. This should occur over a 7-10-day period before moving them to containers, flower beds & borders and hanging baskets.
If you are planting in decorative patio pots or hanging baskets, plant these straight into the pot or hanging basket to be moved outside once the last frost passes.
Mix a light application of a balanced organic fertiliser into the soil prior to planting. In summer, drench plants every two weeks with a liquid fertiliser.
