I bought 2 GORGEOUS calibrachoa with vinca vine hanging baskets at Lowes about 6 weeks ago. They are hanging by my front door which faces west. Initially, they were doing very well, but now are looking leggy and not very pretty, with few blooms. However, the vinca vine is thriving! My questions are what can I do to perk up the million bells, how often should I water and fertilize with Miracle Grow and is it getting enough sun? I've killed several other baskets of it already I assume due to too much water, so I'm being very cautious about overwatering. However, it's getting very hot here in Charleston and I don't want it to suffer from lack of water. Any suggestions would be greatly appreciated.
