I have a problem with my busy lizzys. They have flowered and then the flowers have gone. They have gone all leggy, then they are wilting. What has happened please?

Too much fertilizer can cause leggy plants and reduced flowering. Pinch them back to 6 inches and they should regrow as bushier plants. Leggy plants are also fixed by trimming off the plant so that it looks more like a bush shape.
Wilting may be a sign of stress. This article may help pinpoint the problem: https://www.gardeningknowhow.com/ornamental/flowers/impatiens/impatiens-problems.htm
