Calla lilies are prized for their showy blossoms but over time if they are grown in an area where the temperatures don’t go below freezing, they will become mildly invasive until they take over the planting beds. You can kill off the calla lilies with herbicide and manually cutting them down. After a period of time, the plants will be gone from your yard.



things you’ll need:
  • Broadleaf herbicide
  • Lawn mower
  • Pruning shears
  • Weed whacker
    1. Spray the area with a broadleaf herbicide until you moisten the leaves, following the manufacturer’s directions. Wait for a couple of days so the plant has time to absorb the chemicals into its stem and roots.
    2. Cut down the calla lily plants with a pair of pruning shears, a lawn mower for wide swaths of plants or a weed whacker.
    3. Respray any new plants that sprout after a few weeks with the herbicide, but being careful not to let the spray get on any plants you want to keep.
