Eliminating a Crowded Canna Patch for Gardenia Planting

Removing Established Cannas Without Excessive Digging

Cannas aren't deeply tenacious, but fall is too late for effective herbicide translocation. The practical approach:

1. Now: Cut brown foliage to ground. Spray cut stumps with glyphosate.
2. Winter: Till the bed to expose rhizomes to freezing.
3. Spring: Spot-spray emerging shoots with glyphosate.
4. Then: Plant gardenias among remaining/returning cannas.

Persistence over one season clears the bed with minimal labor.
