    • Q:


      I planted an Ageratina altissima a few months ago and it has taken really well - doubling in size over the Summer.

      However, it's now falling over - the main stems don't seem to be strong enough to support its own weight. Is this normal? Should I be supporting it with canes or has it grown too quickly?

      I have one on the other side of my garden which has grown much more slowly and is still upright.

        These plants are happiest in partial shade, however if the shade is too dense, the plant will become 'stretched' as it reaches for more sun. This rapid, soft growth could be caused by too much fertiliser, so if it is at all possible you should address these issues.. If all else fails however, you could use some discretely placed bamboo canes to prop it up.
