Calibrachoa Can Can Black Cherry produces rich black blooms with a small yellow eye from early spring to early autumn. This mini Petunia works well in 4.5 to 6-in. (11 to 15-cm) pots up to large baskets thanks to its trailing habit. This starter plant grows to a height of 20cm & can spread to as big as 75cm. Place in full sun for best results. How to grow: On delivery of your starter plants it is best to pot them on into a larger container using compost such as John Innes No.2. Keep them protected until all risk of frost has passed. Gradually acclimatise Calibrachoa plants to outdoor conditions by hardening them off over a period of 7 to 10 days. Plant them out in moist well drained soil in a sheltered position. For best results: Feed & water regularly throughout the growing season. Deadhead faded Calibrachoa flowers to encourage more blooms to be produced.
