I'm really pleased with my hanging baskets this year. I grow the flowers from seed in my greenhouse and plant up the baskets when the seedlings are big enough. Then the baskets are hung in the greenhouse for a further 2-3 weeks until the plants are almost ready to bloom. As usual, the day after I hang them outside the Nor'Wester comes and batters them to within an inch of their lives, but the one that is in the most sheltered spot always looks the best all year round:
The trick to getting a nice full looking basket is to simply over plant the basket, (I used 6 of the lobelia plants and 3 petunias), water twice a day and feed every week. Pick off dead flowers every few days. After about 6 weeks of blooming, the flowers will start to look straggly and past their best - chop the whole lot back so the plants are just a couple of inches high (you have to be ruthless), then continue the feeding and watering regime and the baskets will soon give another flush of flowers.
