What to Do With Cosmos in Autumn

As the weather begins to cool and the days grow shorter, many gardeners begin to think about what they should do with their cosmos in autumn. Here are a few ideas: 1. Cut Them Back

If you want your cosmos to bloom again next year, you’ll need to cut them back in the fall. Cut them back by about half their height, and remove any dead or dying leaves or flowers. This will help encourage new growth next spring.

2. Leave Them Be If you’re not worried about getting cosmos blooms next year, then you can simply leave them be. They’ll eventually die back on their own and add some winter interest to your garden.

Just make sure to clean up any dead leaves or flowers so they don’t attract pests or diseases over winter.
