Most Fuchsia baskets for sale right now have been grown on through the winter so that they are nice and full and ready to bloom if they're not already.
All you have to do for the rest of the growing season, is deadhead, water when needed (if your plant is hanging up, lift up slightly, if it feels heavy, don't water). I sometimes stick my finger down the inside of the basket to check for moisture if not sure. Over watering is a sure way to kill your Fuchsia. These baskets have also been fertilized quite heavily so probably won't need any more for about 2 or 3 weeks. If or when your Fuchsia looks long and scraggly you could cut it back some to encourage it to produce new shoots that will flower in 6 or 8 weeks.
