My 2 plants grow very tall. They become topheavy and then fall all over the place. Looks very sloppy.

How can I avoid this?

These can benefit from some light pruning and deadheading, to control their shape and size. It could also be that they are lacking light if they are in a shaded area, or if an area seems to get too dry.
