Weed control in ornamental begins with:

• A. Planting plants in weed-free soil cleaned by crop rotation, cultivation and/or sterilization
• B. Immediate postemergence spraying
• C. Mulching only
• D. Ignoring weed control during establishment

Answer: (A)

The starting point for weed control in ornamentals is preparing the planting site with weed-free soil. This means cleaning and conditioning the bed before planting so weeds don’t get a foothold. Using crop rotation helps reduce the weed seed bank that can recur in the bed, cultivation or tillage disrupts and removes emerging weeds, and sterilization (when practical) eliminates weed seeds and pests present in the soil. Establishing clean soil sets up healthy, uniform establishment of the ornamentals and lowers future competition and herbicide needs. Postemergence spraying is a reactive step taken after weeds have already appeared, which means plants must contend with competition during critical establishment. Mulching is beneficial for suppressing weeds and conserving moisture, but it doesn’t replace the need for clean soil at planting. Ignoring weed control during establishment guarantees faster weed takeover and poorer plant performance, so it’s not a viable approach.
