flower bed is often the focal point of the landscape requiring high
labor input for weed control. Minimal design changes (i.e. grouping
plant species) can be incorporated which reduce maintenance dramatically.
Weeds can be controlled by hand pulling, hoeing, or herbicides.
When a large variety of flowers, or relatively uncommon flowers
are used, weed management with herbicides can be limited. This details
the herbicides that are most widely available for managing weeds
in existing flower beds.
can be used for weed control in existing flower beds. The following
table lists some of the most widely adapted herbicides used on established
flowers for weed control. Selecting flowers for the bed based on
available herbicides can reduce maintenance costs.

With the above
listed products, grasses can be readily controlled and some annual
broadleaves can selectively be controlled in flowers. Check current
specialty product label for timing of applications on each product.
Several other herbicides are available for use on a limited number
of flowers. In addition, glyphosate containing products are readily
available for use around landscape situations.
